Exterior Lamps
The control located to the left of the steering
column operates the exterior lamps.
The exterior lamp control has three positions:
OFF:Turning the control to this position turns
off all lamps except the Daytime Running
Lamps (DRL).
;(Parking Lamps):Turning the control to this
position turns on the parking lamps, together
with the following:
•Marker Lamps
•Taillamps
•License Plate Lamps
•Instrument Panel Lights
O(Headlamps):Turning the control to this
position turns on the headlamps, together with the
previously listed lamps and lights.
You can switch your headlamps from low to high
beam by pulling the turn signal/multifunction
lever toward you. Pull the lever toward you again
to return to low beam.
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 ever happens.
Headlamps on Reminder
If you have this system, a tone will sound when
your headlamps and/or parking lamps are
turned on and your ignition is in LOCK or
ACCESSORY.

Daytime Running Lamps (DRL)
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 lamps
are required on all vehicles first sold in Canada.
The DRL system will make your headlamps come
on at reduced brightness when the following
conditions are met:
•The ignition is on,
•the exterior lamp control 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
the headlamps on. The
other lamps that come
on with your headlamps,
will also come on.
When you turn the headlamps off, the regular
lamps will go off, and your low-beam headlamps
will change to the reduced brightness of DRL.
To idle your vehicle with 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.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
Be sure to clear as much snow from the rear
window as possible.
Press this button which
is located near the fan
control to turn the rear
window defogger on or
off. An indicator light in
the button will come on
when the rear window
defogger is working.
The rear window defogger will only work when the
ignition is in RUN.
The rear window defogger will turn off several
minutes after the button is pressed. The defogger
can also be turned off by pressing the button
again or by turning off the engine.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Outlet Adjustment
Your vehicle has air outlets on the instrument
panel that allow you to adjust the direction
and amount of airflow inside the vehicle.
Move the lever on the outlet up or down to direct
the airflow. Increase or reduce the amount of
airflow by opening and closing the louvers. The
outlets can be moved side-to-side to direct
the airflow.
Operation Tips
•
Keep the hood and front air inlets free of ice,
snow, or any other obstruction (such as
leaves). The heater and defroster will work far
better, reducing the chance of fogging the
inside of your windows.
•Keep the air path under the front seats clear
of objects. This helps air to circulate
throughout your vehicle.
•Adding outside equipment to the front of your
vehicle, such as hood-air deflectors, may
affect the performance of the heating and air
conditioning system. Check with your
dealer before adding equipment to the outside
of your vehicle.

Speedometer and Odometer
Your speedometer lets you see your speed
in both miles per hour (mph) and kilometers per
hour (km/h).
Your odometer shows how far your vehicle
has been driven, in either miles (used in the
United States) or kilometers (used in Canada).
Trip Odometer
The trip odometer can tell you how far your
vehicle has been driven since you last set the trip
odometer to zero.
While the engine is running, press the reset
button, located to the right of the trip odometer, to
toggle between the trip odometer and the
regular odometer. Holding the reset button for
two seconds while the engine is running and the
trip odometer is displayed, will reset it.
To display the odometer reading with the ignition
off, press the reset button.
The hourmeter gage is accessed through the trip
odometer, for more information seeHourmeter
Gage on page 183.
Tachometer
This gage shows the safe operating range for the
engine speed in revolutions per minute (rpm).

Airbag Readiness Light
If your vehicle has airbags, there is an airbag
readiness light on the instrument panel, which
shows the airbag symbol. The system checks the
airbag’s electrical system for malfunctions. The
light tells you if there is an electrical problem. The
system check includes the airbag sensors, the
airbag modules, the wiring, the passenger airbag
suppression circuit and the crash sensing and
diagnostic module. For more information on
the airbag system, seeAirbag System on page 68.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.The airbag readiness light should flash for a few
seconds when you turn the ignition key to RUN or
START. If the light doesn’t come on then, have
it fixed so it will be ready to warn you if there is a
problem.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not in ate in
a crash, or they could even in ate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
