Driving and Operating
Winter Driving
Driving on Snow or Ice
Caution
To avoid damage to the wheels and
brake components, always clear snow and
ice from inside the wheels and
underneath the vehicle before driving.
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
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
Control/Electronic Stability Control
.
The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See
.
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.
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
. 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.
.
Open a window about 5 cm (2 in) on
the vehicle side that is away from the
wind, to bring in fresh air.
.
Fully open the air outlets on or under
the instrument panel.
.
Adjust the climate control system to
circulate the air inside the vehicle and
set the fan speed to the highest
setting. See
“
Climate Control Systems.
