240 Driving and Operating
Avoid driving on wet ice or in
freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently.
Accelerating too quickly
causes the wheels to spin
and makes the surface under
the tires slick.
.Turn on Traction Control.
See Traction Control/
Electronic Stability Control
0267.
.The Antilock Brake System
(ABS) improves vehicle
stability during hard stops,
but the brakes should be
applied sooner than when on
dry pavement. See Antilock
Brake System (ABS) 0264.
.Allow greater following
distance and watch for
slippery spots. Icy patches
can occur on otherwise clear
roads in shaded areas. The
surface of a curve or an
overpass can remain icy
when the surrounding roads are clear. Avoid sudden
steering maneuvers and
braking while on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD)
Mode for vehicles equipped
with AWD. Select Snow/Ice
Mode for FWD only vehicles.
See Driver Mode Control
0
269 and
All-Wheel Drive 0263.
Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan
speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
Blizzard Conditions
Stop the vehicle in a safe
place and signal for help. Stay
with the vehicle unless there is
help nearby. If possible, use Roadside Assistance. See
Roadside Assistance Program
0
439. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine
exhaust under the vehicle.
This may cause exhaust
gases to get inside. Engine
exhaust contains carbon
monoxide (CO), which cannot
be seen or smelled. It can
cause unconsciousness and
even death.
If the vehicle is stuck
in snow:
.Clear snow from the base
of the vehicle, especially
any blocking the
exhaust pipe.

release under other
conditions. Do not rely on HSA
to hold the vehicle.
HSA is available when the
vehicle is facing uphill in a
forward gear, or when facing
downhill in R (Reverse). The
vehicle must come to a
complete stop on a grade for
HSA to activate.
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. On an All-Wheel Drive
(AWD) vehicle in AWD or Sport
Mode, the system will operate
if it senses that any of the
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 system senses a
discrepancy 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 direction
which you are steering.
If cruise control is being used
and traction control or
StabiliTrak/ESC begins to limit
wheel spin, cruise control willdisengage. Cruise control may
be turned back on when road
conditions allow. TCS and
StabiliTrak/ESC will
automatically turn on when
cruise control is set.
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 Stuck
0241 and
“Turning the Systems Off and
On” later in this section.

270 Driving and Operating
Sport Mode modifies steering
efforts, transmission shifting,
and AWD torque, 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 gear
symbol that appears in the
instrument cluster display. See
Performance Shifting Light
0130.
Off-Road Mode : Use this
mode for off-road recreational
driving. When active, Off–Road
Mode should be used to
improve driving at moderate
speeds, on grass, gravel, dirt,
unpaved roads,
or snow-covered roads. The
accelerator pedal is tuned for off-road use. This mode
modifies pedal mapping, AWD,
ESC, and TCS Performance.
Snow/Ice Mode :
Snow/Ice
Mode improves vehicle
acceleration on snow and ice
covered roads. When active,
Snow/Ice Mode will adjust
acceleration to optimize
traction on slippery surfaces.
This can compromise the
acceleration on dry asphalt.
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 0241.
Cruise Control

Warning (Continued)
steady speed. Do not use
cruise control on winding
roads or in heavy traffic.
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
slippery roads.
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).

Using Cruise Control on Hills
How well the 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
your speed. When going
downhill, the cruise control
system may automatically
brake to slow the vehicle
down. Also, you may have to
brake or shift to a lower gear
to keep your speed down.
