Driving and Operating  
If HDC was enabled prior to axle lock, it will  
be automatically enabled when the locking  
front axle is disengaged.  
If equipped with cruise control, a speed of  
about 40 km/h (25 mph) or more can be  
maintained without keeping your foot on  
the accelerator. Cruise control does not work  
at speeds below about 40 km/h (25 mph).  
After pressing the switch to unlock the axle,  
it may remain locked due to torque in the  
driveline. The axle is more easily unlocked  
by turning the steering wheel to the right  
and to the left while traveling at a low  
speed.  
If the cruise control is being used and the  
Traction Control System (TCS) or StabiliTrak/  
Electronic Stability Control (ESC) begins to  
limit wheel spin, the cruise control will  
automatically disengage. See Traction  
Control/Electronic Stability Control 0 237. If a  
collision alert occurs when cruise control is  
activated, cruise control is disengaged. See  
Forward Collision Alert (FCA) System 0 284.  
When road conditions allow you to safely  
use it again, cruise control can be turned  
back on.

Cruise control can be dangerous where  
you cannot drive safely at a steady  
speed. Do not use cruise control on  
winding roads or in heavy traffic.  
+RES : If there is a set speed in memory,  
press the control up briefly to resume to  
that speed or press and hold to accelerate.  
If cruise control is already engaged, use to  
increase vehicle speed.  
Turning off the TCS or StabiliTrak/ESC  
system will disengage the cruise control.  
Cruise control can be dangerous on  
slippery roads. On such roads, fast  
changes in tire traction can cause  
excessive wheel slip, and you could lose  
control. Do not use cruise control on

ACC uses a windshield mounted front  
camera sensor.  
Warning  
{
ACC has limited braking ability and may  
not have time to slow the vehicle down  
enough to avoid a collision with another  
vehicle you are following. This can occur  
when vehicles suddenly slow or stop  
ahead, or enter your lane. Also see  
Alerting the Driverlater in this section.  
Complete attention is always required  
while driving and you should be ready to  
take action and apply the brakes. See  
Defensive Driving 0 195.

Do Not Use ACC on Hills  
When towing a trailer with ACC, it is  
important to properly set the Trailer Gain.  
See Integrated Trailer Brake Control  
Systemin Towing Equipment 0 307 for  
Trailer Gain Adjustment Procedure.  
Conditions that are associated with low  
visibility, such as fog, rain, snow, or road  
spray, may limit ACC performance. Water  
droplets from rain or snow that remain on  
the windshield may also limit ACCs ability  
to detect objects.  
Use Tow/Haul mode when driving down  
steep hills or mountain grades, or when  
hauling heavy loads. See Driver Mode  
Control 0 240.  
System operation may be limited under  
snow, heavy rain, or road spray conditions.  
Warning  
{
Disengaging ACC  
Do not use ACC when driving on steep hills  
as ACC may not detect a vehicle ahead.  
Camera visibility may be limited and the  
ACC system may not work properly if the  
windshield is not clear. Do not use ACC if  
moisture is present on the inside of the  
windshield or the windshield washer is  
used in cold weather. Turn on the front  
defroster and make sure the windshield is  
clear before using ACC. Before driving,  
check that the windshield wipers are in  
good condition and replace them if worn.  
There are three ways to disengage ACC:
