You can switch your headlamps from high to low beam
by pulling on the turn signal/high beam lever.
A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will flicker on
and off. Have your headlamp wiring checked right away
if this happens.
Headlamps On Reminder
A tone will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY.
If you need to use your headlamps when the ignition
switch is in OFF, LOCK or ACCESSORY, the tone
can be turned off by moving the thumbwheel next to the
parking lamp/headlamp switch all the way down.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lights are required on all
vehicles first sold in Canada.The DRL system will make your headlamps come
on at a reduced brightness when the following
conditions are met:

The ignition is on,

The headlamp switch is off, and

The parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.
When it begins to get dark, your DRL indicator light
is a reminder to turn your headlamp switch on. The
other lamps that come on with your headlamps will
also come on.
When you turn off the headlamp switch, the regular
lamps will go off, and your headlamps will change to
the reduced brightness of DRL.
To idle your vehicle with the engine on and the DRL off,
set the parking brake. The DRL will stay off until you
release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-42 Center High-Mounted Stoplamp

above the rear doors at the center of the vehicle.
If items are loaded on the roof of the vehicle, as in a
luggage carrier, care should be taken not to block or
damage the center high
-mounted stoplamp unit.
Interior Lamps
Dome Lamps
The dome lamps will come on when you open a door.
You can also turn the dome lamps on by moving the
thumbwheel, located next to the headlamp knob, all the
way up to the second detent. In this position, the dome
lamps will remain on whether a door is open or closed.

on when you start your
engine and may stay on
for several seconds.

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.

-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.

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.
See ªEngine Overheatingº in the Index.

setting. Turn the knob toward the red area for warmer air.
Turn the knob toward the blue area for cooler air.
Mode Knob
The right knob on the control panel changes the
heater/air conditioning setting.
MAX A/C: Turn the right knob to MAX A/C for
maximum cooling. This setting puts the system in the
recirculation mode and helps to maximize your air
conditioner's performance and your vehicle's fuel

the vehicle's interior reaches a comfortable temperature,
turn the knob clockwise to place the air conditioning
system in the A/C mode.

for floor vent airflow or clockwise for headliner vent air
flow. Generally, the upper vents are used for air
conditioning and the floor vents for heating. The control
knob can be set to any blend setting.
To adjust the airflow speed, turn the fan knob on the left
side of the control panel to the desired fan speed.
To activate the rear control, turn the fan knob on the
