2(Headlamps):This position turns on the
headlamps, parking lamps, and taillamps.
;(Parking Lamps):This position turns on the
parking lamps and taillamps only.
AUTO (Automatic Headlamp System):This position
automatically turns on the Daytime Running Lamps
during daytime, and the headlamps, parking lamps, and
taillamps at night.
P(Off/On):This position is the momentary Off/On
switch for the Automatic Headlamp System. In Canada,
this only works when the vehicles with an automatic
transmission are in PARK (P) and vehicles with a
manual transmission have the parking brake set.
When operating in AUTO, a momentary turn of the
switch to off/on will turn off the Automatic Headlamp
System. An AUTO LIGHTS OFF message will display on

The Automatic Headlamp System is always turned on at
the beginning of an ignition cycle for vehicles with
manual transmission. When the parking brake is on, the
automatic headlamps will turn off. For vehicles with
automatic transmission, when the gear is shifted out of
PARK, the Automatic Headlamp System will turn on.
Shifting the gear back to PARK (P) will turn off the
automatic headlamp system for vehicles with an
automatic transmission.
Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on. For this
feature to work, automatic lighting must be enabled. See
Headlamps on page 3-13for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also turn
off 15 seconds after the windshield wiper control is
turned off.
Headlamps on Reminder
If you open the driver’s door with the ignition off and the
lamps on, you will hear a warning chime.
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 rst sold in Canada.
Your vehicle has a light sensor on top of the instrument
panel. Make sure it is not covered or the headlamps
will come on when you do not need them.
The DRL system will make both front turn signal lamps
turn on when the following conditions are met:
The ignition is on.
The exterior lamp control is turned to AUTO.
The light sensor detects daytime light.
The shift lever is not in PARK (P).
While the DRL system is on, the taillamps, sidemarker
lamps, and instrument panel lights will not be
illuminated.
The DRL system will be off any time your vehicle is in
PARK (P). The DRL system on U.S. vehicles can
also be turned off by using the off/on switch for one
ignition cycle.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
as you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s
advice. Waiting to do repairs can be costly — and even
dangerous. So please get to know your warning
lights and gages. They’re a big help.

You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to re-adjust 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 lm caused by dust. Dirty glass makes
lights dazzle and ash 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.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you cannot stop, accelerate, or turn as well
because your tire-to-road traction is not as good as on
dry roads. And, if your tires do not have much tread
left, you will get even less traction. It is always wise to
go slower and be cautious if rain starts to fall while
you are driving. The surface may get wet suddenly when
your reexes are tuned for driving on dry pavement.

Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives uid from the brake master cylinder
reservoir.
SeeBrakes on page 5-36for more information.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-29.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
