much too low.
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate
in All-Wheel Drive (AWD) Mode. See
Driver Mode Control0248.
Press MODE to activate AWD. AWD is
active in both AWD and Sport Modes.
The AWD system delivers power to all
four wheels and the system adjusts as
needed to improve traction. The AWD Mode will stay selected
until the mode is changed. If the
vehicle is placed in Sport Mode, see
Driver Mode Control
0248.
Sport Mode is canceled with each
ignition cycle. See Driver Mode Control
0 248.
When operated in Tour Mode, the
vehicle will deliver power to the front
wheels only and may provide better
fuel economy.
If Tour Mode is selected see Driver
Mode Control 0248.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake
boost have hydraulic brake circuits
that are 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.
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while braking hard.
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.
If there is a problem with ABS, this
warning light stays on. See
Antilock
Brake System (ABS) Warning Light
0 118.

parking brake warning light is on, see
your dealer.
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.
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.
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 red
parking brake status light is off. 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.
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.
If you are towing a trailer and parking
on a hill, see Driving Characteristics
and Towing Tips 0305.
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 0217.

will come on in the instrument cluster
and stay on.
Driver Mode Control Switch
Tour : Tour Mode operates in FWD to
improve fuel economy. Use this mode
during normal driving operations.
Sport : Sport Mode improves vehicle
handling and acceleration on dry
pavement. When active, Sport Mode
modifies steering efforts, transmission
shifting, AWD, ESC, engine sound
enhancement, and suspension tuning,
if equipped.
The Performance Algorithm Liftfoot
(PAL) feature is enabled in Sport
Mode. PAL allows the transmission to
hold the current gear after a quick release of a heavily applied accelerator
pedal. This provides greater engine
braking and enhanced vehicle control.
When PAL is activated, there may be
an additional green gear symbol which
appears in the instrument cluster
display. See
Performance Shifting Light
0 119.
AWD : AWD Mode provides drive
torque to all four wheels. Select AWD
to improve traction and control on
slippery road surfaces, such as gravel,
sand, wet pavement, snow, and ice.
When in AWD Mode, the AWD Mode
indicator light will be on. For more
information on AWD Mode, see
All-Wheel Drive 0244.
Snow/Ice (FWD Vehicles Only) :
Snow/Ice Mode improves vehicle
acceleration on snow and ice covered
roads.

Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to increase
the vehicle speed. When you take your
foot off the pedal, the vehicle will slow
down to the previous set cruise speed.
While pressing the accelerator pedal
or shortly following the release to
override cruise, briefly moving the
thumbwheel down toward SET− will
result in cruise set to the current
vehicle speed. Using Cruise Control on Hills
How well cruise control will work on
hills depends upon the vehicle speed,
load, and the steepness of the hills.
When going up steep hills, you might
have to step on the accelerator pedal
to maintain speed. When going
downhill, the cruise control system
may automatically brake to slow the
vehicle. 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).
.PressJ.
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
(Advanced)
If equipped, Adaptive Cruise Control
(ACC) allows the cruise control set
speed and following gap to be
selected. 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 0421.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
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 system activates, ACC
may automatically disengage. See
Traction Control/Electronic Stability
Control 0247. When road conditions
allow ACC to be safely used, ACC can
be turned back on.

place the vehicle in P (Park) and
turn off the ignition before leaving
the vehicle.
ACC Override
If using the accelerator pedal while
ACC is active, the ACC indicator turns
blue on the instrument cluster and in
the HUD (if equipped) indicating ACC
braking will not occur. ACC will
resume operation when the
accelerator pedal is not being pressed.
{Warning
The ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
