Recirculation ButtonWhen the indicator in the button is on,
air from the vehicle's interior is sent
throughout the system again. When the
indicator is off, air is brought in from the
outside of the vehicle (fresh air mode).
The outside air intakes for the climate
control system are at the base of the
windshield. Keep this area clear of leaves
and other debris.
The system should be left in fresh air
mode under almost all conditions.
Keeping the system in recirculation
mode, particularly with the A/C off, can
cause the windows to fog up.
Switch to recirculation mode when
driving through dusty or smoky
conditions, then return to fresh air mode.Rear Window Defogger ButtonThis button turns the rear window
defogger off and on (see page 131).
Pushing this button also turns the
power mirror heaters on and off.
Mode ControlUse the mode control button to
select the vents the air flows from.
Some air will flow from the
dashboard vents in all modes.
Air flows from the center and
corner vents in the dashboard.Airflow is divided between the
vents in the dashboard and the floor
vents.Air flows from the floor vents.Airflow is divided between the
floor and corner vents and the
defroster vents at the base of the
windshield.
Windshield Defroster ButtonThis button directs the main airflow
to the windshield for faster
defrosting. It also overrides any
mode selection you may have made. When you select
, the system
automatically switches to fresh air
mode and turns on the A/C. For
faster defrosting, manually set the
fan speed to high. You can also
increase airflow to the windshield by
closing the corner vents on the
dashboard. To close the vents, rotate
the wheel under each corner vent.
When you turn off
by pressing
the button again, the system returns
to its former settings.
For your safety, make sure you have
a clear view through all the windows
before driving.
When the indicator in the button is
on, the front passenger's and rear
passenger compartment
temperatures cannot be set
separately from the driver's.

●
Are you using the proper starting
procedure? Refer toStarting the
Engine on page 436.
●
Do you have fuel? Check the fuel
gauge; the warning indicator may
not be working.
●
There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses (see
page 560).
If you find nothing wrong, you will
need a qualified technician to find the
problem. See Emergency Towing on
page 566. Jump Starting
Although this seems like a simple
procedure, you should take several
precautions.
A battery can explode if you do
not follow the correct
procedure, seriously injuring
anyone nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
You cannot start your vehicle by
pushing or pulling it.
To Jump Start Your Vehicle:1. Open the hood, and check the physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or frozen, do not try
jump starting until it thaws.If a battery sits in extreme cold, the
electrolyte inside can freeze. Attempting
to jump start with a frozen battery can
cause it to rupture.
2. Turn off all the electricalaccessories: heater, A/C, climate
control, audio system, lights, etc.
Put the transmission in neutral or
Park, and set the parking brake.
