Rear Doors
CAUTION:
It can be dangerous to drive with the rear doors
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the rear doors open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
rear doors:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on VENT, HEAT, BLEND or DEF.
Additionally, on vehicles with heating/air
conditioning systems, NORM A/C or
BI
-LEVEL A/C can be used. That will
force outside air into your vehicle. See
ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
To open the rear doors from the outside, pull the handle
towards you to open the passenger's side rear door first.

NOTICE:
Holding a cigarette lighter in with your hand
while it is heating can make it overload,
damaging the lighter and the heating element.
Just push the lighter all the way in and let go.
When it's done, it will pop back by itself.
To remove the front ashtray, pull up on the tab with a
key or screwdriver inserted in the tab, and lift the
ashtray out.
Sun Visors
To block out glare, you can swing down the visors. You
can also swing them from side to side.
Visor Vanity Mirror (Option)
Some visors have mirrors built in, with or without
lamps. Just lift the mirror cover on each visor to turn the
lamps on, if you have them.
Accessory Power Outlets
You can plug auxiliary electrical equipment into
accessory power outlets. Just pull on the outlet cover
and follow the proper installation instructions that are
included with any electrical equipment that you install.
One accessory power outlet is located on the passenger's
side of the front storage compartment.
These circuits are protected by a fuse and have
maximum current levels.
NOTICE:
When using the accessory power outlets, maximum
electrical load must not exceed 25 amps. Always
turn off any electrical equipment when not in use.
Leaving electrical equipment on for extended
periods will drain your battery.

2-56 Anti-Lock Brake System Warning Light
United States Canada
With the anti
-lock brake system, this light will come on
when you start your engine and may stay on for several
seconds. That's normal.
If the light stays on, or comes on when you're driving,
your vehicle needs service. If the regular brake system
warning light isn't on, you still have brakes, but you
don't have anti
-lock brakes. If the regular brake system
warning light is also on, you don't have anti
-lock brakes
and there's a problem with your regular brakes. See
ªBrake System Warning Lightº earlier in this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area your engine is
too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal
operating conditions, you should pull off the road, stop
your vehicle, and turn off the engine as soon as possible.
The ªProblems on the Roadº section of this manual
shows what to do. See ªEngine Overheatingº in
the Index.

To decrease airflow, turn it toward LO. To turn the fan
off, turn the mode knob on the far right to OFF.
Temperature Knob
The middle knob on the control panel controls the
temperature of the air flowing into your vehicle. Turn
the knob toward the red area for warmer air. Turn the

conditioning controls will look like this.
Before using your vehicle's air conditioning, open the

temperature, turn the knob clockwise to place the
air conditioning system in the A/C mode.
