Shifting Into Park
1. Hold the brake pedal down and
set the parking brake. See
Electric Parking Brake 0196.
2. Move the shift lever into P (Park) by holding in the
button on the shift lever and
pushing the shift lever all the
way toward the front of the
vehicle.
3. Turn the ignition off.
Leaving the Vehicle with the
Engine Running
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire. (Continued)
Warning (Continued)
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park 0188.
If you are towing a trailer, see
Driving Characteristics and
Towing Tips 0233.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is set before you
leave it. After you have moved the
shift lever into P (Park), hold the
regular brake pedal down. Then, see if you can move the shift lever
away from P (Park) without first
pressing the button.
If you can, it means that the shift
lever was not fully locked in
P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not
done properly and then it is difficult
to shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see
“Shifting Into Park”
listed previously.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).

196 Driving and Operating
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a
Yor PARK
Electric Parking Brake light, and
some vehicles may have a
8
Service Parking Brake light. See
Electric Parking Brake Light 0127
and
Service Electric Parking Brake Light
0 127.
Before leaving the vehicle, check for
the
Yor PARK light to ensure that
the parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Lift up the EPB switch momentarily.
The
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK light
flashes continuously, then the EPB
is only partially applied, the vehicle
is in Service Mode, or there is a
problem with the EPB. A Driver
Information Center (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
Yor
PARK light is flashing. See your
dealer. See Electric Parking Brake
Light 0127.
If the
8light is on or theYor
PARK light flashes when the ignition
is turned on, pull the EPB switch
and hold it. Continue to hold the
switch until the
Yor PARK light
remains on. If the
8light remains
on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
pulled. If the switch is pulled until
the vehicle comes to a stop, the
EPB will remain applied.
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.
If the EPB fails to apply, block the
rear wheels to prevent vehicle
movement.

EPB Release
To release the EPB:1. Turn the ignition on or to ACC/ ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
Y
or PARK light is off.
If the
8light is on or theYor
PARK light flashes, release the EPB
by pressing and holding the EPB
switch. Continue to hold the switch
until the
Yor PARK light is off.
If either light stays on after release
is attempted, see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
(Continued)
Caution (Continued)
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
If parking on a hill, or if the vehicle
is pulling a trailer, see Driving
Characteristics and Towing Tips
0 233.
Automatic EPB Release
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.
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 apply the brake
pedal as the driving situation
dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
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
0167.
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

covered roads. The accelerator
pedal will be more sensitive to
provide finer control of the torque at
the wheels in slippery conditions.
7(AWD Only) :Vehicle is in
Off-Road Mode. This mode will not
remain active through future ignition
cycles. The vehicle will be in
Two-Wheel Drive when the engine
is restarted. This mode will
automatically activate AWD. The
accelerator pedal will be more
sensitive to provide finer control of
the torque at the wheels.
StabiliTrak/ESC, ABS, and TCS will
change for optimal off-road
performance. Use this mode for
public off-road recreational driving.
See Off-Road Driving 0170.
_Tow/Haul : Vehicle is in Tow/

remain active through future ignition
cycles. The vehicle will be in
Front-Wheel Drive or Two-Wheel
Drive when the engine is restarted.
This mode will automatically
activate AWD. See All-Wheel Drive
0 194. The transmission holds lower
gears longer before shifting to provide more torque necessary
when towing heavy loads. This will
also increase fuel consumption. Use
this mode to assist in maintaining
desired vehicle speeds when driving
on downhill grades by using the
engine and transmission to slow the
vehicle. This helps prevent the
brakes from overheating. For more
information, see
Tow/Haul Mode

to use engine braking to slow the
vehicle and maintain the set speed.
Also, you may have to brake or shift
to a lower gear to keep your speed
down. If the brake pedal is applied,
cruise control disengages.
Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. Press
J.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
Jis
pressed or if the ignition is
turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire section before using this system.
The following gap is the following
time between your vehicle and a
vehicle detected directly ahead in
your path, moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses camera
and radar sensors. See
Radio
Frequency Statement 0355.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the Traction Control
System (TCS) or StabiliTrak/
Electronic Stability Control (ESC)
system activates, the ACC may
automatically disengage. See
Traction Control/Electronic Stability
Control 0198. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
Turning off the TCS or StabiliTrak/
ESC system will disengage the
cruise control.
{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 Driver” 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 0167.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
