Engine Coolant Heater (If Equipped)
In very cold weather, 0” F (- 18 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
/1 CAUTION:
Plugging the cord into an ungrounded outlet
could cause
an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt AC outlet.
If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts.
If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged in? The answer depends
on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

FIRST (1): This position gives you even more power
(but lower fuel economy) than
SECOND (2). You can
use it on very steep hills, or in deep snow or mud.
If
the selector lever is put in FIRST (l), the transaxle
won't
shift into first gear until the vehicle is going
slowly enough.
NOTICE:
If your front wheels can't rotate, don't try to
drive. This might happen
if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into
PARK (P)
to hold your vehicle in position on a hill.
Performance Shifting (Option)
Press PERFORM SHIFI' to
allow the transaxle to shift
at higher engine speeds,
increasing acceleration
performance.
An indicator
light on the switch will
glow when performance
shifting is
in operation.
Downshifts will occur at a lower percentage
of
accelerator application while you're in the PERFORM
SHIFT mode.
Press NORMAL SHIFT to have the transaxle shift at
lower engine speeds, increasing fuel economy.
An
indicator light on the switch will glow when normal
shifting is in operation.

If you try to drive away with the parking brake on, the
brake light stays on and a chime sounds until you release
the parking brake.
NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You may have to
replace them, and you could also damage other
parts of your vehicle.

If you are towing a trailer and are parking on any hill,
see “Towing a Trailer” in the Index. That section shows
what to do first to keep the trailer from moving.
Shifting Into PARK (P)
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. If
you have 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, use the
steps that
follow.
If you’re pulling a trailer, see “Towing a
Trailer” in the Index.
Steering Column Shift Lever
1. Hold the brake pedal down with your right foot and
set
the parking brake.

Console Shift Lever Leaving Your Vehicle With
the
Engine Running
1. Hold the brake pedal down with your right foot and
2. Move the shift lever into PARK (P) like this:
set the parking brake.
,I
0 Hold in the button on the lever.
0 Push the lever all the way toward the front of
the vehicle.
3. Move the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK
(P).
A CAUTION:
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move
suddenly
if the shift lever is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running,
it could
overheat and even catch fire. You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After you’ve moved the shift lever into the PARK (P)
position, hold the regular brake pedal down. Then,
see if
you can move the shift lever away from PARK (P)
without first pulling it toward you (or,
if you have the
console shift lever, without first pushing
the button). If
you can, it means that the shift lever wasn’t fully locked
into PARK (P).

The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the button
located on the center console, the warning light will come on and stay on.
To turn the system back on,
press the button again.
The warning light should go
off. (See “Traction Control System” in the Index
for more information.)

’ If you have this light and it
comes on, your system may
be low on coolant and the
engine may overheat.
If there’s a brake system problem that is specifically
related to traction control, the traction control system will turn
off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will

If the traction control system warning light comes on
and stays on for
an extended period of time when the
system is turned on, your vehicle needs service. Check to see if
the level is low at the recovery tank, and
add coolant
if necessary. If the level is not low, have
your low coolant warning system serviced. See “Engine
Coolant” in the Index.
The
LOW COOLANT warning light will also come on
when you
turn on the ignition, but your engine is not
running, as a check to show you it is working. If it
doesn’t come on then, have it fixed right away.
After the bulb check, the light will
go out for 20
seconds. If the light comes back on after 20 seconds, the
system may be low on coolant. See “Engine Coolant”
in the Index.

Engine Coolant Temperature Gage
280
This gage shows the engine
coolant temperature.
If the gage pointer moves
into
the red area, your
engine is too hot! On
vehicles
with the optional
DIC, the CHECK GAGES
light will go on and a
warning chime will sound.
It means that your engine coolant has overheated.
If you
have been operating your vehicle under normal driving
conditions, you should pull
off the road, stop your
vehicle and
turn off the engine as soon as possible.
In the section “Problems
on the Road,” this manual
explains what to
do. See “Engine Overheating” in
the Index.
Malfunction Indicator Lamp (Check Engine Light)
CHECK 0
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
CHECK ENGINE 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.

When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2.
Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer.
See the Maintenance Schedule for more
on
this. Things that are especially important in trailer
operation
are automatic transaxle fluid (don’t overfill),
engine oil, belt(s), cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before
you start
your trip.
Check periodically to see that all hitch nuts and bolts
