Steering Wheel 0110.Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar
intensity.
The climate control system
uses the sensor information to
adjust the temperature, fan
speed, recirculation, and air
delivery mode for best
comfort. If the sensor is covered, the
automatic climate control
system may not work properly.
Afterblow Feature
If equipped, under certain
conditions, the fan may stay

Driving and Operating 241
Warning (Continued)
.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.”
For more information about
CO, see Engine Exhaust
0 256.
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the
engine off and partially close
the window. Moving about to
keep warm also helps.
If it takes time for help to
arrive, when running the
engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
If stuck too severely for the
traction system to free the
vehicle, turn the traction
system off and use the rocking
method. See Traction Control/
Electronic Stability Control

{Warning
If the vehicle's tires spin at
high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the

wheels as little as possible
and avoid going above
56 km/h (35 mph).
For All-Wheel Drive (AWD),
select Off-Road or AWD mode.
See Driver Mode Control
0 269 and
All-Wheel Drive 0263.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until
the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when
the transmission is in gear.
Slowly spinning the wheels in

due to corrosion or
damage.
.The vehicle exhaust
system has been modified,
damaged, or improperly
repaired.
.There are holes or
openings in the vehicle
body from damage or
aftermarket modifications
that are not completely
sealed.(Continued)
Warning (Continued)

detected or if it is suspected
that exhaust is coming into
the vehicle:
.Drive it only with the
windows completely down.
.Have the vehicle repaired
immediately.
Never park the vehicle with
the engine running in an
enclosed area such as a
garage or a building that has
no fresh air ventilation.
Running the Vehicle
