Maintenance
Passenger Compartment
Air Filter
Both outside and recirculated air
are routed through a passenger
compartment air filter. Pollen, dust
particles and other contaminants
are removed by the filter. Airflow
reductions indicate that the filter
needs to be replaced. For a
replacement filter see your dealer/
retailer. See Scheduled Maintenance
on page 10-3 for replacement
intervals. The access panel for the air filter is
behind the glove box. To replace
the filter:

7-4 Climate Controls

Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program on page 12-6 .
To get help and keep everyone in the
vehicle safe:
•Turn on the hazard warning
flashers.
•Tie a red cloth to an outside
mirror.
{CAUTION
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.
(Continued)
CAUTION (Continued)
If the vehicle is stuck in the snow:
•Clear away snow from
around the base of your
vehicle, especially any that is
blocking the exhaust pipe.
•Check again from time to
time to be sure snow does
not collect there.
•Open a window about 5 cm
(two inches) on the side of
the vehicle 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 a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in the
Index.(Continued)
CAUTION (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 8-23 .
Snow can trap exhaust gases
under your vehicle. This can cause
deadly CO (carbon monoxide) gas
to get inside. CO could overcome
you and kill you. You cannot see it
or smell it, so you might not know it
is in your vehicle. Clear away snow
from around the base of your
vehicle, especially any that is
blocking the exhaust.
Run the engine for short periods only
as needed to keep warm, but be
careful.

8-34 Driving and Operating

Cruise Control
For vehicles with cruise control, the
lever is located on the right side
of the steering wheel.Cruise control, lets a speed of
25 mph (40 km/h) or more be
maintained without keeping your foot
on the accelerator. Cruise control
does not work at speeds below
25 mph (40 km/h).
{CAUTION
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the 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.Setting Cruise Control
{CAUTION
If you leave your cruise control on
when you are not using cruise,
you might hit a button and go into

8-36 Driving and Operating

Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer won’t strike soft shoulders,
curbs, road signs, trees or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes or stopping. When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. For this reason you may
think other drivers are seeing the
signal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the transmission
is not shifted down, the brakes
might have to be used so much that
they would get hot and no longer
work well.
Vehicles with an automatic
transmission can tow in D (Drive).
Shift the transmission to a lower gear
if the transmission shifts too often
under heavy loads and/or hilly
conditions. For vehicles with a
manual transmission, it is better
not to use the highest gear.When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at a
lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. For vehicles with manual
transmissions, let the engine run
while parked, preferably on level
ground, with the transmission out of
gear and the parking brake applied,
for a few minutes before turning the
engine off. If the overheat warning
comes on, see
Engine Overheating
on page 9-23.
