Daytime Running Lamps (DRL) /
Automatic Headlamp Control
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.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't covered.
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 off,

the transaxle is not in PARK (P) and

the parking brake is released.When the DRL are on, only your low
-beam headlamps,
at a reduced brightness, will be on. The taillamps,
sidemarker and other lamps won't be on. Your
instrument panel won't be lit up either.
When it's dark enough outside, your headlamps will
change to full brightness. The other lamps that come on
with your headlamps will also come on.
When it's bright enough outside, the headlamps will go
out, 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 while the ignition is in OFF or LOCK. Then start
your vehicle. The DRL will stay off until you shift out
of PARK (P) and release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Battery Saver
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave the
interior, trunk or underhood lamps on. If you leave
any of these lamps on while the ignition is in LOCK or
OFF, they will automatically turn off after 10 minutes.
The lamps won't come back on again until you do
one of the following:

Turn the ignition to RUN or ACCESSORY.

Turn the interior lamp thumbwheel completely to the
right, then back slightly to the left.

Open (or close and reopen) a door that is closed.
If the vehicle has less than 15 miles (25 km) on the
odometer, the battery saver will turn off the lamps after
only three minutes.
Mirrors
Adjust all the mirrors so you can see clearly when you
are sitting in a comfortable driving position.
Inside Day/Night Rearview Mirror
To reduce glare from lamps behind you, pull the lever
located in the center of the bottom of the mirror toward
you to the night position. To return the mirror back to
the day position, push the lever away from you.
Electrochromic Day/Night Rearview
Mirror with Compass and Temperature
Display (Option)
Your vehicle may have an automatic-dimming rearview
mirror with a compass and temperature display.
When turned on, an electrochromic mirror automatically
dims to the proper level to minimize glare from
headlamps behind your after dark.
The mirror has an eight
-point compass and temperature
display in the upper right corner of the mirror face. The
display shows the current outside temperature and the
vehicle's current direction.

To adjust the HUD so you can see it properly do
the following:
1. Adjust your seat, if necessary, to a
comfortable position.
2. Start the engine and adjust the HUD controls located
on the instrument panel, to the right of the steering
wheel. Move the DIM thumbwheel up or down to
adjust brightness.3. Press the top of the UP/DN switch until the HUD
image stops moving. Then press the bottom of the
switch until the image is as low as possible but in
full view.
4. Move the DIM thumbwheel down until the HUD
image is no brighter than necessary. To turn the HUD
off, move the DIM thumbwheel all the way down.
If the sun comes out, it becomes cloudy, or if you turn
on your headlamps, you may need to adjust the HUD
brightness again. Polarized sunglasses could make the
HUD image harder to see.
Push the ENG/MET button
on the trip calculator,
located above the audio
controls on the trip
computer (if equipped) on
the instrument panel, to
switch the HUD display
from English to metric or
metric to English.
If your vehicle is not equipped with the trip calculator,
you cannot change the display.

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.Here are some tips on night driving.

Drive defensively.

Don't drink and drive.

Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.

Since you can't see as well, you may need to
slow down and keep more space between you and
other vehicles.

Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.

In remote areas, watch for animals.

If you're tired, pull off the road in a safe place
and rest.

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're
driving, don't 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
doesn't 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's 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
aren't even aware of it.

CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.

Headlamp Aiming
The aim of your vehicle's headlamps can be adjusted by
using aim tips located on the outer surface of the lens.
The aim has been pre
-set at the factory and should need
no further adjustment.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
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, it is recommended that
you take your vehicle to the dealer for assistance.
