Winter Driving
Driving on Snow or Ice
Caution
To avoid damage to the wheels and brake
c
o
mponents, always clear snow and ice
from inside the wheels and underneath the
vehicle before driving.
Snow or ice between the tires and the road
c
r
eates 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.
•
Tu
rn on Traction Control. See Traction
Control/Electronic Stability Control 3178.
•
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) 3175.
•
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
St
op 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 3 302. 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
S
now can trap engine exhaust under the
ve
hicle. 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.
