panel cluster will flash in
the direction of the

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 low-beam headlamps
come on at a reduced brightness when the following
conditions are met:
•The ignition is on,
•the exterior lamps control is in AUTO or the parking
lamps only position,
•the light sensor detects daytime light,
•the parking brake is released, and
•the shift lever is not in PARK (P) on vehicles with
an automatic transaxle only.
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps and instrument panel lights
will not be illuminated unless you have turned the
exterior lamps control to the parking lamp position.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Delayed Headlamps
The delayed headlamps feature will continue to
illuminate the headlamps for 20 seconds after the key is
turned to OFF, then the headlamps will automatically
turn off.
To override the 20 second delayed headlamp feature
while it is active turn the turn signal/multifunction
lever up one position and then back to AUTO.
Fog Lamps
If your vehicle has this feature, the button for your fog
lamps is located on the instrument panel, to the left
of the steering wheel, beside the instrument panel
brightness thumbwheel.
When using the fog lamps, the ignition must be on as
well as the parking lamps or the low-beam headlamps.
Press the button to turn the fog lamps on and off.
An indicator light on the button will glow while the fog
lamps are on.
The fog lamps will turn off while the high-beam
headlamps are turned on.
Interior Lamps
Instrument Panel Brightness
The thumbwheel for this
feature is located on the
instrument panel to the left
of the steering wheel.
Move the thumbwheel up to brighten the lights and
down to dim them.

No one can see as well at night as in the daytime. But
as we get older these differences increase. A
50-year-old driver may require at least twice as much
light to see the same thing at night as a 20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your
eyes will have less trouble adjusting to night. But if you
are driving, do not wear sunglasses at night. They
may cut down on glare from headlamps, but they also
make a lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When
you are faced with severe glare (as from a driver
who does not lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid
staring directly into the approaching headlamps.Keep your windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your eyes
moving; that way, it is easier to pick out dimly lighted
objects. Just as your headlamps should be checked
regularly for proper aim, so should your eyes be
examined regularly. Some drivers suffer from night
blindness — the inability to see in dim light — and are not
even aware of it.

Headlamp Aiming
Your vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has been
pre-set at the factory and should need no further
adjustment. This is true even though your vertical and
horizontal aim indicators may not fall exactly on the
“0” (zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment may be necessary
if it is difficult to see lane markers (for horizontal
aim), or if oncoming drivers flash their high beams at
you (for vertical aim). If you believe your headlamps
need to be re-aimed, we recommend that you take it to
your dealer for service; however, it is possible for
you to re-aim your headlamps as described in the
following procedure.Notice:To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.
To check the aim, the vehicle should be properly
prepared as follows:
•The vehicle must have all four tires on a perfectly
level surface.
•If necessary, pads may be used on an uneven
surface.
•The vehicle should not have any snow, ice or mud
attached to it.
•The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
•There should not be any cargo or loading of the
vehicle, except it should have a full tank of fuel and
one person or 160 lbs. (75 kg) on the driver’s seat.
•Close all doors.
•Tires should be properly inflated.
•Rock the vehicle to stabilize the suspension.
