{Warning
Do not rely on this feature.
It 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.
When Automatic Vehicle Hold
(AVH) is turned on and the
vehicle is braked to a stop,
AVH prevents the vehicle from
moving during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
The brakes may also release
under other conditions. Do not
rely on AVH to hold the
vehicle.
If the accelerator pedal is not
applied within a few minutes,
the Electric Parking Brake will apply. The parking brake will
also apply if the driver door is
opened or the driver seat belt
is unfastened while AVH is
holding the vehicle.
AVH can be turned on by
pressing AUTO HOLD. The
indicator light on the switch
will come on. The AVH light on
the instrument panel will come
on while AVH is actively
holding the vehicle. See
Automatic Vehicle Hold (AVH)
Light
0122.
Ride Control
Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction
Control System (TCS) and
StabiliTrak/Electronic Stability
Control (ESC). These systems
help limit wheel slip 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,
the system brakes the
spinning wheel(s) and/or
reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates
when the computer senses a
difference between the
intended path and the
direction the vehicle is actually
traveling. StabiliTrak/ESC
selectively applies braking
pressure at any one of the
vehicle's brakes to help steer
the vehicle in the intended
direction.
If cruise control is being used
and TCS or StabiliTrak/ESC
begins to limit wheel spin,
cruise control will disengage.
Cruise control may be turned
back on when road conditions
allow.

Driving and Operating 291
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. See If
the Vehicle Is Stuck0255 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 may
display 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.
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.

Driver Mode Control
Driver Mode Control (DMC)
allows the driver to adjust the
overall driving experience to
better suit driver preference
by adjusting vehicle systems
to fit specific driving needs.
Drive mode availability and
affected vehicle systems are
dependent on vehicle trim
level, region, and optional
features.
If the vehicle is in Tour Mode
or My Mode, it will stay in that
mode through future ignition
cycles. If the vehicle is in any
other mode, it will return to
Tour Mode when the vehicle is
restarted. When a mode is
selected, an indicator will
come on in the instrument
cluster and stay on.

Mode Description
Tour Mode
Use for normal city and
highway driving to provide a
smooth, soft ride. This mode
provides a balance between
comfort and handling. This is
the standard mode. See
“Mode Selection Attributes”
later in this section. When
Tour Mode is selected, no
indicator will display.Sport Mode
Use this mode where road
conditions or personal
preference demand a more
controlled response. When
this mode is selected, the
vehicle immediately
downshifts. The vehicle also
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 this feature
and return to normal operation
after a short period when
spirited driving is no longer
detected. The steering
changes to provide more
precise control. If the vehicle
has Magnetic Ride Control, the
suspension changes to
provide better cornering
performance.See
“Mode Selection
Attributes” later in this
section.
Snow/Ice Mode
Use this mode for slippery
surfaces to help control wheel
speed. This mode can
compromise the acceleration
on dry asphalt.
This feature is not intended
for use when the vehicle is
stuck in sand, mud, or gravel.
If the vehicle is stuck, see If
the Vehicle Is Stuck 0255.
See “Mode Selection
Attributes” later in this
section.
Track Mode (V-Series Only)
When in Track Mode, the
automatic transmission and
steering function similar to
Sport Mode. The accelerator
pedal is adjusted to give
maximum control during the
highest level of spirited
driving. The Magnetic Ride
