Running Your Engine While You're
Parked (Automatic Transmission)
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the fan is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
See ªBlizzardº in the Index.
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Four-wheel drive vehicles with the transfer case
in NEUTRAL will allow the vehicle to roll,
even if your shift lever is in PARK (P). So, be
sure the transfer case is in a drive gear
-- not in
NEUTRAL. Always set your parking brake.
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº in
the Index.

2-44 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 lamps are required on all
vehicles first sold in Canada.
The DRL system will make your headlamps come on
at a reduced brightness when the three following
conditions are met:

The ignition is on with the engine running,

the exterior lamps control is off or the parking
lights are on, and

the parking brake is released.When the DRL are on, only your headlamps will be on
at a reduced brightness. The taillamps, sidemarker and
other lamps won't be on. Your instrument panel won't
be lit up either.
When you move the exterior lamps control to the
headlamp position, your DRL will go off and your
headlamps will come on. The other lamps that
come on with your headlamps will also come on.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular
headlamps. See ªAutomatic Light Controlº following.
When you turn the exterior lamp control to off, the
regular lamps will go off and your headlamps will
change to the reduced brightness of DRL provided
it is not dark outside. DRL will also come on if only
the parking lamps are being used.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-45 Automatic Light Control (ALC)
Your vehicle is equipped with an automatic light sensor
on top of the instrument panel, so be sure it is not covered.
If it is, the headlamps will remain on continuously.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the ALC
systems so that driving under bridges or bright overhead
street lights does not affect the system. The DRL and
ALC systems will only be affected when the light sensor
sees a change in lighting lasting longer than this delay.
When it is dark enough outside, or you are driving
through a parking garage, heavy overcast weather or
a tunnel, the ALC will turn on your low
-beam
headlamps at normal brightness. Along with your
vehicle's headlamps, the taillamps, sidemarker, parking
lamps and the instrument panel lights will also turn on.
The radio lights will dim.
When the vehicle is initially started in darkness with the
parking brake engaged, there is a delay before the ALC
will turn on the lights.
As with any vehicle, you should turn on the regular
headlamps when you need them.To disable your vehicle's DRL and ALC functions,
do the following:
1. Before turning the ignition key to ON or START,
set the parking brake.
2. Then turn the ignition key to ON or START.

The ALC will not turn on under any conditions,
even in darkness.

The DRL will not turn on.
The DRL and ALC functions will stay off with the
ignition on, until you release the parking brake.
Once the parking brake is released the DRL will
turn on (if it is daylight) or the ALC will turn on
(if it is dark enough outside).
If you turn the ignition key to ON or START and
then set the parking brake, the DRL will turn off
(in all conditions) and the ALC will remain on (if dark
enough outside). Any other uses of the parking brake
after the engine is turned on will have no effect on the
normal ALC operation.
Lamps On Reminder
If you turn the ignition off, remove the key, open the
door and leave the lamps on, a tone will remind you to
turn off your lamps.

2-67 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).
Your vehicle's odometer is tamper
-resistant.
You may wonder what happens if your vehicle needs a
new odometer installed. If possible, the new one is to
be set to the same reading as the old one. If it can't be,
then it's set at zero. Then a label is attached on the
driver's door to show the old reading and when the
new one was installed.Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
The button located to the right of the odometer display
allows you to switch between the odometer and the two trip
odometers. Press the button once to switch to TRIP A
and again to switch to TRIP B. To return the display to
the odometer reading, press the trip odometer button again.
To set the trip odometers to zero, press and hold the button.
Tachometer
The tachometer shows engine speed in thousands of
revolutions per minute (rpm). You can use it while
driving to select correct shift points. The tachometer
may not return to zero when the engine is not running.
NOTICE:
Do not operate the engine with the tachometer
in the red area, or engine damage may occur.

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 briefly 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
when 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.
Safety Belt Reminder Light
When the key is turned to ON or START, a tone will
come on for several seconds to remind people to fasten
their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light
will also come on and
stay on until the driver's
belt is buckled.

2-70 Charging System Light
This light will come on
briefly when you turn on the
ignition, but the engine is
not running, as a check to
show you it is working.
Then it should go out when
the engine starts.
If the light stays on or comes on while you are driving,
you may have a problem with the electrical charging
system. It could indicate that you have a loose generator
drive belt or another electrical problem. Have it checked
right away. Driving while this light is on could drain
your battery.
If you must drive a short distance with this light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The light
will stay on if your parking brake doesn't release fully.
If it stays on after your parking brake is fully released,
it means you have a brake problem.
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.

2-72 Anti-Lock Brake System Warning
Light (Option)
With the anti-lock brake
system, this light will
come on when you start
your engine and it will
stay on for three seconds.
That's normal.
If the light comes on when you're driving, you don't
have anti
-lock brakes and there could be a problem with
your regular brakes. Pull off the road and stop carefully.
You may notice that the pedal is harder to push. Or, the
pedal may go closer to the floor. It may take longer to
stop. Have the vehicle towed for service. See ªTowing
Your Vehicleº in the Index.
CAUTION:
Your regular brake system may not be working
properly if the anti
-lock brake system warning
light is on. Driving with the anti
-lock brake
system warning light on can lead to an accident.
After you've pulled off the road and stopped
carefully, have the vehicle towed for service.
If the anti-lock brake system warning light stays on
longer than normal after you've started your engine,
turn the ignition off. Or, if the light comes on and stays
on when you're driving, stop as soon as possible and
turn the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on again
while you're driving, your vehicle needs service. If the
light is on and the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti
-lock brakes.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

2-73 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves to the
H (red) side, your engine
is too hot.
It means that your engine coolant has overheated and
you should stop your vehicle and turn off the engine
as soon as possible.
The ªProblems on the Roadº section of this manual
shows what to do. See ªEngine Overheatingº in
the Index.
Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.
