electronically controlled when the brake

pedal is applied during normal operation.

The system performs routine tests and turns

off within a few minutes after the vehicle is

turned off. Noise may be heard during this

time. If the brake pedal is pressed during

the tests or when the electric brake boost

system is off, a noticeable change in pedal

force and travel may be felt. This is normal.

If there is a problem with ABS, this warning

light stays on. See Antilock Brake System

(ABS) Warning Light 0 120.

The actual 4x4 shift request is only made

after the button is released. The 4x4 graphic

will remain flashing until the shift request

has completed. A DIC message displays.

ABS does not change the time needed to

get a foot on the brake pedal and does not

always decrease stopping distance. If you

get too close to the vehicle ahead, there will

not be enough time to apply the brakes if

that vehicle suddenly slows or stops. Always

leave enough room ahead to stop, even

with ABS.

Once the 4x4 shift has completed, the DIC

message disappears, the 4x4 graphic stops

flashing, and the current setting is indicated.

Antilock Brake System (ABS)

The Antilock Brake System (ABS) helps

prevent a braking skid and maintain steering

while braking hard.

Using ABS

A DIC message displays. Once the 4x4 shift

has completed, the DIC message disappears,

the 4x4 graphic stops flashing, and the

current setting is indicated.

Do not pump the brakes. Just hold the brake

pedal down firmly. Hearing or feeling ABS

operate is normal.

ABS performs a system check when the

vehicle is first driven. A momentary motor

or clicking noise may be heard while this

test is going on, and the brake pedal may

move slightly. This is normal.

Braking in Emergencies

ABS allows steering and braking at the same

time. In many emergencies, steering can

help even more than braking.

Driving and Operating

Before leaving the vehicle, check the red

parking brake status light to ensure that the

parking brake is applied.

If the EPB is applied while the vehicle is

moving, the vehicle will decelerate as long

as the switch is pressed. If the switch is

pressed until the vehicle comes to a stop,

the EPB will remain applied.

Electric Parking Brake

EPB Apply

To apply the EPB:

The vehicle may automatically apply the EPB

in some situations when the vehicle is not

moving. This is normal, and is done to

periodically check the correct operation of

the EPB system, or at the request of other

safety functions that utilize the EPB.

1. Be sure the vehicle is at a complete stop.

2. Press the EPB switch momentarily.

The red parking brake status light will flash

and then stay on once the EPB is fully

applied. If the red parking brake status light

flashes continuously, then the EPB is only

partially applied or there is a problem with

the EPB. A DIC message will display. Release

the EPB and try to apply it again. If the

light does not come on, or keeps flashing,

have the vehicle serviced. Do not drive the

vehicle if the red parking brake status light

is flashing. See your dealer.

If the EPB fails to apply, block the rear

wheels to prevent vehicle movement.

EPB Release

The Electric Parking Brake (EPB) can always

be applied, even if the vehicle is off. In case

of insufficient electrical power, the EPB

cannot be applied or released. To prevent

draining the battery, avoid unnecessary

repeated cycles of the EPB.

To release the EPB:

1. Turn the ignition on or to

accessory mode.

2. Apply and hold the brake pedal.

3. Press the EPB switch momentarily.

If the amber service parking brake warning

light is on, press the EPB switch. Continue to

hold the switch until the red parking brake

status light remains on. If the amber service

parking brake warning light is on, see your

dealer.

The EPB is released when the red parking

brake status light is off.

The system has a red parking brake status

light and an amber service parking brake

warning light. See Electric Parking Brake

Light 0 119 and Service Electric Parking Brake

Light 0 120. There are also parking

brake-related Driver Information Center (DIC)

messages.

If the amber service parking brake warning

light is on, release the EPB by pressing and

holding the EPB switch. Continue to hold the

switch until the red parking brake status

light is off. If either light stays on after

release is attempted, see your dealer.

Driving and Operating

237

apply the brake pedal as the driving

situation dictates. Brake Assist disengages

when the brake pedal is released.

HSA is available when the vehicle is facing

uphill in a forward gear, or when facing

downhill in R (Reverse). The vehicle must

come to a complete stop on a grade for HSA

to activate.

Caution

Driving with the parking brake on can

overheat the brake system and cause

premature wear or damage to brake

system parts. Make sure that the parking

brake is fully released and the brake

warning light is off before driving.

Hill Start Assist (HSA)

Warning

{

Ride Control Systems

Do not rely on the HSA feature. HSA does

not replace the need to pay attention

and drive safely. You may not hear or

feel alerts or warnings provided by this

system. Failure to use proper care when

driving may result in injury, death,

or vehicle damage. See Defensive Driving

0 195.

Traction Control/Electronic

Stability Control

If you are towing a trailer and parking on a

hill, see Driving Characteristics and Towing

Tips 0 299.

System Operation

Automatic EPB Release

The vehicle has a Traction Control System

(TCS) and StabiliTrak/Electronic Stability

Control (ESC), an electronic stability control

system. These systems help limit wheel spin

and assist the driver in maintaining control,

especially on slippery road conditions.

The EPB will automatically release if the

vehicle is running, placed into gear, and an

attempt is made to drive away. Avoid rapid

acceleration when the EPB is applied, to

preserve parking brake lining life.

When the vehicle is stopped on a grade, Hill

Start Assist (HSA) prevents the vehicle from

rolling in an unintended direction during the

transition from brake pedal release to

accelerator pedal apply. The brakes release

when the accelerator pedal is applied. If the

accelerator pedal is not applied within a few

minutes, the Electric Parking Brake will

apply. The brakes may also release under

other conditions. Do not rely on HSA to hold

the vehicle.

TCS activates if it senses that any of the

drive wheels are spinning or beginning to

lose traction. When this happens, TCS

applies the brakes to the spinning wheels

and reduces engine power to limit

wheel spin.

Brake Assist

Brake Assist detects rapid brake pedal

applications due to emergency braking

situations and provides additional braking to

activate the Antilock Brake System (ABS) if

the brake pedal is not pushed hard enough

to activate ABS normally. Minor noise, brake

pedal pulsation, and/or pedal movement

during this time may occur. Continue to

StabiliTrak/ESC activates when the vehicle

senses a difference between the intended

path and the direction the vehicle is actually

traveling. StabiliTrak/ESC selectively applies
