Running Your Engine While You’re
Parked (Automatic rnansrnission)
It’s better not to park with the engine running. But if you ever have to, here
are
some things to know.
I CAUTION
I A Idling the engine with the air system control off could allow
A dangerous exhaust into your vehicle. (See the earlier Caution under
“Engine Exhaust”.)
Also, idling in a closed-in place can let deadly carbon monoxide (CO)
into your vehicle even if the fan switch is at the highest setting. One
place this can happen is a garage. Exhaust-with Chan come in
easily.
NEVER park in a garage with the engine running.
Another closed-in
place can be a blizzard, {See “Blizzard” in the
Index.)
It can be dangerous to get out of your vehicle if the shift lever is not
fully in 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 P (Park).
If you have four-wheel drive, and you’re transfer case is in N (Neutral),
your vehicle will be free to roll, even if your shift lever is in P (Park).
So, be’ sure the transfer case is in a drive gear-not in N (Neutral).
Follow
the proper steps to be sure -your vehicle won? move. See
“Shifting
Into Park” in the tndex.
If you are parking on a hill, or if you’re pulling a trailer, also see
“Parking on Hills” or “Trailer Towing” in the Index.

four-wheel drive, you must be familiar with its operation. Read the pan that
follows before using four-wheel drive. You
should use 2H for most normal
driving conditions.

Driving in the 4H or 4L positions for a long time on dry or wet pavement
could shorten the life of your vehicle’s drivetrain.

Featurns & Cuntmls
lnsfrument Cluster
Your instrument cluster is designed to let you know at a glance how your.
vehicle is running. You'll know
how fast you're going, about how much fuel
you have,
and many other things you'll need to know to drive safely and
economically.
Tachometer Cluster
If you have the tachometer cluster, it looks slightly different but will tell you
everything the standard cluster does, in addition to displaying the vehicles
engine revolutions per minute (rpm).
Speedometer and Odometer
I
..
K2322
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 U.S.) or kilometers (used in
Canada).
Tamper Resistant Odometer
Your odometer is tamper-resistant, The odometer will show silver line\
s
between the numbers
if someone tries to turn it back.
You may wonder what happens if your vehicle needs a new odome\
ter installed.
If the new one can be set to the mileage total of the old odometer,
tien
it must be. But if it can't, then it's set at zero, and a label must be put
on the driver's
door to show the old mileage reading when the new odometer
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.
To reset the trip odometer, fully press the reset button located near the
readout.
If the reset button is not fully pressed, the trip odometer may not go
all the way back to zero. If it doesn’t, you may have to press the reset
button again to reset the readout to zero.
Tachometer
K2324
If you have a tachometer, it displays the engine speed in revolutions per

Warning Lights, Gages and lndicafors
This part describes the warning lights and gages that are on \
your vehicle.
The pictures will help you locate them.
Warning lights and gages can signal that something is wrong be\
fore 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 go 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 turn the ignition\
key just
to let
you know they’re working.
If you are familiar with this part, 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
part that tells you what to
do about it. Please follow the 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.

Charging System Light

K2328
The red charging system light is located at the upper right hand corner of
your instrument cluster. It should come on briefly when you turn on the
ignition, before starting the engine, as a check
to show you it is working.
After the engine starts, the light should go out.
If it stays on, or comes on
while you are driving, you may have a problem with your elect\
rical charging
system. It could indicate that you have a loose alternator drive belt, or that
you have some other 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 the light on, be certain to turn off all
your accessories, such as the radio and air conditioner.

Malfunction Indicator Lamp (Service Engine Soon Light)
RVI
llrll
I
K2329
A computer monitors operation of your fuel, ignition and emission control
systems. This light should come on when the ignition is on,
but the engine is
not running, as a check
to show you it is working. If it does not come on at
all, have it fixed right away. If it stays on, or comes on while you are driving,
the computer is indicating that you have a problem. You should take your
vehicle in
for service soon.
If you keep driving your vehicle with this light on, after awhile the emission
controls won’t work as well, your fuel economy won’t be as good, and
your engine may not
run as smoothly. This could lead to costly repairs not
covered
by your warranty. I
