220 DRIVING AND OPERATING
Automatic Vehicle
Hold (AVH)
Automatic Vehicle Hold (AVH),
if equipped, can be turned on by
pressing AUTO HOLD with the driver
seat belt fastened, the driver door
closed, and the engine running. The
AVH indicator will come on.This feature will activate when the
vehicle is stopped to prevent it from
moving. After the brake pedal has
been released and before the
accelerator pedal has been pressed,
AVH uses braking pressure to hold the
vehicle stationary. In addition, the
ABS pump motor may activate to
build brake pressure to maintain the
vehicle at a standstill if necessary.
If AVH is holding the vehicle, the AVH
indicator will change to green. Once
AVH is active it will hold the vehicle
for a defined time period then engage
the parking brake. While AVH is
holding the vehicle, the parking brake
will engage if the driver door is
opened or the driver seat belt is
unfastened. See
Automatic Vehicle Hold
(AVH) Light 0144.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC).
These systems help limit wheel spin
and assist the driver in maintaining
control, especially on slippery road
conditions.
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.
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
braking pressure to any one of the
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.

DRIVING AND OPERATING 221
If cruise control is being used and
traction control or StabiliTrak/ESC
begins to limit wheel spin, cruise
control will disengage. Cruise control
may be turned back on when road
conditions allow.
Both systems come on automatically
when the vehicle is started and begins
to move. The systems may be heard or
felt while they are operating or while
performing diagnostic checks. This is
normal and does not mean there is a
problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary to
turn TCS off if the vehicle gets stuck
in sand, mud, ice, or snow. SeeIf the
Vehicle Is Stuck 0196 and “Turning
the Systems Off and On ”later in this
section.
The indicator light for both systems is
in the instrument cluster. This
light will:
. Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak/ESC is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to indicate
that the system is inactive and is not
assisting the driver in maintaining
control. The vehicle is safe to drive,
but driving should be adjusted
accordingly. If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
4. Drive the vehicle.
If
dcomes on and stays on, the
vehicle may need more time to
diagnose the problem. If the condition
persists, see your dealer.

Mode Description
The following describes the modes
that can be selected in further detail.
Tour Mode
Use for normal city and highway
driving to provide a smooth, soft ride.
This setting provides a balanced
setting between comfort and handling.
This is the standard mode. For further
details on Tour Mode, see “Driver
Mode Selector Attributes Affected ”.
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When selected, the Sport Mode
indicator light will display in the
instrument cluster. In this mode, the vehicle monitors
driving behaviors and automatically
enables Performance Shift Features
when spirited driving is detected.
These features maintain lower
transmission gears to increase
available engine braking and improve
acceleration response. The vehicle will
exit these features and return to
normal operation after a short period
when no spirited driving is detected.
The steering including Active Rear
Steer (if equipped), will change to
provide more precise control. If the
vehicle has Magnetic Ride Control, the
suspension will change to provide
better cornering performance. If the
vehicle is equipped with AWD, Sport
Mode sends more torque to the rear
wheels.
For further details on Sport Mode, see
“Driver Mode Selector Attributes
Affected”.

224 DRIVING AND OPERATING
Snow/Ice Mode
Snow/Ice Mode is used for slippery
surfaces to help control wheel speed.
This can compromise the acceleration
on dry asphalt. Use when maximum
vehicle handling is desired. Snow/Ice
Mode will use a different accelerator
pedal map to optimize traction on a
slippery surface. The accelerator pedal
will reduce engine torque at small
pedal inputs.
When selected, the Snow/Ice Mode
indicator light will display in the
instrument cluster.This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, see
If the
Vehicle Is Stuck 0196.
If the vehicle is equipped with AWD,
Snow/Ice Mode will provide more
torque to the front wheels.
For further details on Snow/Ice Mode,
see “Driver Mode Selector Attributes
Affected”.
Track Mode (V-Series Only)
Use when maximum vehicle handling
is desired.
When selected, the Track Mode
indicator will display in the
instrument cluster.
When in Track Mode, the automatic
transmission and the accelerator pedal
is adjusted to give maximum control
during the highest level of spirited
driving. The Magnetic Ride Control
and steering will be set to the
optimum level for vehicle
responsiveness.

over each ignition cycle. They do not
have to be reset each time the vehicle
is started.
Locking Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow, mud,
ice, sand, or gravel. When traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. The limited-slip rear axle
also gives the driver enhanced control
when cornering hard or completing a
maneuver, such as a lane change. For
vehicles with limited-slip rear axle, the
rear axle fluid should be changed. See
