128 STARTING AND OPERATING

NOTE:

Transmission Limp Home Mode

Even if the transmission can be reset, we recommend that

you visit an authorized dealer at your earliest possible

convenience. An authorized dealer has diagnostic

equipment to assess the condition of your transmission.

If the transmission cannot be reset, an authorized dealer

service is required.

Transmission function is monitored electronically for

abnormal conditions. If a condition is detected that could

result in transmission damage, Transmission Limp Home

Mode is activated. In this mode, the transmission may

operate only in certain gears, or may not shift at all.

Vehicle performance may be severely degraded and the

engine maystall. In some situations, thetransmission may

not re-engage if the engine is turned off and restarted.

The Malfunction Indicator Light (MIL) may be illuminated.

A message in the instrument cluster will inform the driver

of the more serious conditions, and indicate what actions

may be necessary.

Electronic Range Select (ERS) Operation —

If Equipped

The ERS shift control allows the driver to limit the highest

available gear when the transmission is in DRIVE and ERS

mode is not active. For example, if you set the

transmission gear limit to FOURTH gear, the transmission

will hold that gear and not shift above FOURTH gear, but

will shift through the lower gears normally.

Electronic Range Select (ERS)

1 — Shift Up “+”

In the event of a momentary problem, the transmission

can be reset to regain all forward gears by performing the

following steps:

2 — Shift Down “–”

NOTE:

To exit ERS mode, simply push and hold the “+” button

until the gear limit display disappears from the instrument

cluster.

NOTE:

ERS will only upshift during a FIRST to SECOND gear shift

when in 4WD LOW. All other ranges will hold the gear.

In cases where the instrument cluster message indicates

the transmission may not re-engage after engine

shutdown, perform this procedure only in a desired

location (preferably, at an authorized dealer).

You can switch between DRIVE and ERS mode at any

vehicle speed. When the transmission gear selector is in

DRIVE, the transmission will operate automatically,

shifting between all available gears. Tapping the “-” button

(on the steering wheel) will activate ERS mode, display the

currentgear in the instrument cluster, and set that gear as

the top available gear. Once in ERS mode, tapping the “-”

or “+” button will change the top available gear.

WARNING!

Do not downshift for additional engine braking on a

slippery surface. The drive wheels could lose their grip

and the vehicle could skid, causing a collision or

personal injury.

1. Stop the vehicle.

2. Shift the transmission into PARK, if possible. If not,

shift the transmission to NEUTRAL.

3. Push and hold the ignition switch until the engine

turns off.

4. Wait approximately 30 seconds.

5. Restart the engine.

6. Shift into the desired gear range. If the problem is no

longer detected, the transmission will return to

normal operation.

STARTING AND OPERATING 129

Operation

 The system will ignore attempts to upshift at too low of

a vehicle speed.

AutoStick — If Equipped

In AutoStick mode, you can use the gear selector (in the

SPORT position), or the paddle shifters, to manually shift

the transmission. To activate AutoStick mode, move the

gear selector into the SPORT (S) position (beside the

DRIVE position), or tap one of the paddle shifters on the

steering wheel. Tapping the “-” shift paddle to enter

AutoStick mode will downshift the transmission to the next

lower gear, while tapping “+” to enter AutoStick mode will

retain the current gear. The current transmission gear will

be displayed in the instrument cluster.

AutoStick is a driver-interactive transmission feature

providing manual shift control, giving you more control of

the vehicle. AutoStick allows you to maximize engine

braking, eliminate undesirable upshifts and downshifts,

and improve overall vehicle performance. This feature can

also provide you with more control during passing, city

driving, cold slippery conditions, mountain driving, trailer

towing, and many other situations.

 Holding the “-” paddle pressed, or holding the gear

selector in the “-” position, will downshift the transmis-

sion to the lowest gear possible at the current speed.

 Transmission shifting will be more noticeable when

AutoStick is enabled.

 The system may revert to automatic shift mode if a

fault or overheat condition is detected.

NOTE:

When Selec-Speed or Hill Descent Control is enabled,

AutoStick is not active.

AutoStick mode has the following operational benefits:

 The transmission will automatically downshift as the

vehicle slows (to prevent engine lugging) and will

display the current gear.

To disengage AutoStick, return the gear selector to the

DRIVE position, or press and hold the “+” paddle shifter

(and the gear selector is already in DRIVE) until "D" is once

again indicated in the instrument cluster. You can shift in

or out of AutoStick at any time without taking your foot off

the accelerator pedal.

 The transmission will automatically downshift to FIRST

gear when coming to a stop. After a stop, the driver

should manually upshift “+” the transmission as the

vehicle is accelerated.

 You can start out, from a stop, in FIRST or SECOND gear

(or THIRD gear, in 4WD LOW). Tapping “+” (at a stop)

will allow starting in SECOND gear. Starting out in

SECOND or THIRD gear can be helpful in snowy or icy

conditions.

WARNING!

Paddle Shifters

Do not downshift for additional engine braking on a

slippery surface. The drive wheels could lose their grip

and the vehicle could skid, causing a collision or

personal injury.

1 — “-” Paddle

2 — “+” Paddle

 If a requested downshift would cause the engine to

overspeed, that shift will not occur.

130 STARTING AND OPERATING

When to Use TOW/HAUL Mode

WARNING!

Select TOW/HAUL mode when driving in conditions such

as: driving in hilly areas, towing a trailer, carrying a heavy

load, etc. This mode will improve performance and reduce

the potential for transmission overheating or failure due to

excessive shifting.

Do not use the TOW/HAUL feature when driving in icy or

slippery conditions. The increased engine braking can

cause the rear wheels to slide, and the vehicle to swing

around with the possible loss of vehicle control, which

may cause an accident possibly resulting in personal

injury or death.

FOUR-WHEEL DRIVE OPERATION —

IF EQUIPPED

FOUR-POSITION ELECTRONICALLY

SHIFTED TRANSFER CASE —

IF EQUIPPED

Four-Position/On-Demand Transfer Case

This electronically shifted transfer case provides four

positions:

 Two-Wheel Drive High Range (2WD) — This range is for

normal street and highway driving on dry hard surfaced

roads. Driving the vehicle in 2WD will have greater fuel

economy benefits as the front axle is not engaged in

2WD.

TOW/HAUL Switch

This is an electronic shift transfer case and is operated by

the 4WD Control Switch (Transfer Case Switch), located on

the instrument panel.

The TOW/HAUL Indicator Light will illuminate in the

instrument cluster to indicate that TOW/HAUL mode has

been activated. Pushing the switch a second time restores

normal operation. Normal operation is always the default

at engine start-up. If TOW/HAUL mode is desired, the

switch must be pushed each time the engine is started.

 Four-Wheel Drive High Range (4WD HIGH) — This range

provides torque to the front driveshaft (engages

four-wheel drive) which allows front and rear wheels to

spin at the same speed. This provides additional

traction for loose or slippery road surfaces only.

STARTING AND OPERATING 131

 Four-Wheel Drive Low Range (4WD LOW) — This range

provides low speed four-wheel drive. It maximizes

torque (increased torque over 4WD HIGH) to the front

driveshaft; allowing front and rear wheels to rotate at

the same speed. This range provides additional trac-

tion and maximum pulling power for loose or slippery

road surfaces only. Do not exceed 25 mph (40 km/h)

in this range.

If the transfer case does not shiftinto the desired position,

one or more of the following events may occur:

NOTE:

 The 4WD HIGH and 4WD LOW positions are designed

for loose, slippery road surfaces only. Driving in the

4WD HIGH and 4WD LOW positions on dry, hard

surfaced roads may cause increased tire wear and

damage to the driveline components.

1. The indicator light for the current position will

remain on.

2. The newly selected position indicator light will

continue to flash.

 The transfer case N (Neutral) button is located in the

center of the 4WD Control Switch and is pushed by

using a ballpoint pen or similar object. The transfer

case N (Neutral) position is to be used for recreational

towing only Ú page 187.

3. If the transfer case will not shift, a message will

appear on the cluster stating the 4WD shift has

canceled.

 N (Neutral) — This range disengages both the front and

rear driveshafts from the powertrain. To be used for flat

towing behind another vehicle Ú page 187.

NOTE:

Before retrying a selection, make certain that all the

necessary requirements for selecting a new transfer case

position have been met. To retry the selection, push the

current position, wait five seconds, and retry selection.

Transfer Case Position Indicator Lights

WARNING!

The Transfer Case Position Indicator Lights (4WD HIGH

and 4WD LOW) are located in the instrument cluster and

indicate the current and desired transfer case selection.

When you select a different transfer case position, the

indicator lights will do the following:

 You or others could be injured or killed if you leave

the vehicle unattended with the transfer case in the

N (Neutral) position without first fully engaging the

parking brake. The transfer case N (Neutral) position

disengages both the front and rear drive shaft from

the powertrain, and will allow the vehicle to roll, even

if the transmission is in PARK. The parking brake

should always be applied when thedriver is notin the

vehicle.

The SERV 4WD Warning Light monitors the electronic shift

four-wheel drive system. If this light remains on after

engine start-up or illuminates during driving, it means that

the four-wheel drivesystem is not functioning properly and

that service is required.

1. The current position indicator light will turn off.

2. The selected position indicator light will flash until the

transfer case completes the shift.

WARNING!

3. When the shift is complete, the indicator light for the

selected position will stop flashing and remain on.

 The transmission may not engage PARK if the vehicle

is moving. Always bring the vehicle to a complete

stop before shifting to PARK, and verify that the

transmission gear position indicator solidly indicates

PARK (P) without blinking. Ensure that the vehicle is

completely stopped, and the PARK position is prop-

erly indicated, before exiting the vehicle.

Always engage the parking brake when powering down

the vehicle if the SERV 4WD Warning Light is

illuminated. Not engaging the parking brake may allow

the vehicle to roll which may cause personal injury or

death.

132 STARTING AND OPERATING

This electronically shifted transfer case provides five

positions:

NOTE:

FIVE-POSITION ELECTRONICALLY

SHIFTED TRANSFER CASE —

IF EQUIPPED

This is an electronic shift transfer case and is operated by

the 4WD Control Switch (Transfer Case Switch), which is

located on the instrument panel.

Do not attempt to make a shift while only the front or rear

wheels are spinning. This could cause damage to driveline

components.

 Two-Wheel Drive High Range (2WD) — This range is for

normal street and highway driving on dry hard surfaced

roads. Driving the vehicle in 2WD will have greater fuel

economy benefits as the front axle is not engaged in

2WD.

When operating your vehicle in 4WD LOW, the engine

speed is approximately three times that of the 2WD or

4WD HIGH positions at a given road speed. Take care not

to overspeed the engine and do not exceed 25 mph

(40 km/h).

 Four-Wheel Drive Automatic High Range (4WD AUTO) —

This range sends power to the front wheels automati-

cally when the vehicle senses a loss of traction. This

range may be used during varying road conditions.

Proper operation of four-wheel drive vehicles depends on

tires of equal size, type and circumference on each wheel.

Any difference in tire size can cause damage to the

drivetrain.

 Four-Wheel Drive High Range (4WD HIGH) — This range

provides torque to the front driveshaft (engages

four-wheel drive) which allows front and rear wheels to

spin at the same speed. This provides additional trac-

tion for loose or slippery road surfaces only.

Because four-wheel drive provides improved traction,

there is a tendency to exceed safe turning and stopping

speeds. Do not go faster than road conditions permit.

 Four-Wheel Drive Low Range (4WD LOW) — This range

provides low speed four-wheel drive. It maximizes

torque (increased torque over 4WD HIGH) to the front

driveshaft; allowing front and rear wheels to rotate at

the same speed. This range provides additional trac-

tion and maximum pulling power for loose or slippery

road surfaces only. Do not exceed 25 mph (40 km/h)

in this range.

Shifting Procedure

 If any of the requirements to select a new transfer case

position have not been met, then the transfer case will

not shift. The position indicator light for the previous

position will remain on and the newly selected position

indicator light will continue to flash until all the require-

ments for the selected position have been met.

Five-Position/On-Demand Transfer Case

 If all the requirements to select a new transfer case

position have been met, then the current position indi-

cator light will turn off and the selected position indi-

cator light will flash until the transfer case completes

the shift. When the shift is complete, the position indi-

cator light for the selected position will stop flashing

and remain on.

 N (Neutral) — This range disengages both the front and

rear driveshafts from the powertrain. To be used for flat

towing behind another vehicle Ú page 187.

cally lowered to OR1. Off-Road 2 may not be available

due to vehicle payload, an instrument cluster message

is displayed when this occurs Ú page 98.

 Normal Ride Height (NRH) – This is the standard posi-

tion of the suspension and is meant for normal driving.

 Aero Height (Lowers the vehicle approximately0.6 inch

[15 mm]) – This position provides improved aerody-

namics by lowering the vehicle. The vehicle will auto-

matically enter Automatic Aero Mode when the vehicle

speed remains between 62 mph (100 km/h) and

66 mph (106 km/h) for greater than 20 seconds or if

the vehicle speed exceeds 66 mph (106 km/h).

STARTING AND OPERATING 135

The vehicle will return to NRH from Aero Mode if the

vehicle speed remains between 30 mph (48 km/h)

if the vehicle speed falls below 30 mph (48 km/h).

To return to Normal Height Mode, push the height

selector switch up once while in Entry/Exit or drive the

vehicle over 15 mph (24 km/h).

Default Ride Height:

 Select Aero Height or Normal Ride Heightas thedefault

for all vehicle speeds and operation. This is the

selected height that the suspension will level for speed

changes (e.g. raising from Entry/Exit Height at speed,

lowering from Off-Road Height at speed, etc.).

NOTE:

Entry/Exit Height may be achieved using the Remote

Lowering feature on your key fob for easier entry/loading

Ú page 16.

 Automatic Aero mode will be disabled if a trailer is

detected to prevent shifting loads.

 Default ride height can be changed by manually

adjusting the Air Suspension switch to Normal Ride

Height or Aero Ride Height and staying in the selected

height for 2.5 seconds. It will be stored as the default

ride height and the height will be maintained until a

new default ride height is selected.

 Speed thresholds for raising/lowering the vehicle

automatically at higher speeds only apply if

be closed. If a door is opened at any time while the vehicle

is lowering, the change will not be completed until the

open door(s) is closed.

NOTE:

Automatic Aero Mode may be disabled through vehicle

settings in the instrument cluster display Ú page 98 or

through your Uconnect Radio (if equipped) Ú page 191.

WARNING!

The air suspension system uses a high pressure

volume of air to operate the system. To avoid personal

injury or damage to the system, see an authorized

dealer for service.

This system uses a lifting and lowering pattern which

keeps the headlights from incorrectly shining into

oncoming traffic. When raising the vehicle, the rear of the

vehicle will move up first and then the front. When

lowering the vehicle, the front will move down first and

then the rear.

 Entry/Exit Height (Lowers the vehicle approximately

2 inches [51 mm]) – This position lowers the vehicle

for easier passenger entry and exit as well as lowering

the vehicle for easier loading and unloading of cargo.

To enter Entry/Exit Mode, push the height selector

switch down once from the NRH while the vehicle

speed is below 33 mph (53 km/h). Once the vehicle

speed goes below 15 mph (24 km/h) the vehicle
