2-20 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord for the engine coolant heater is in
front of the air cleaner filter and under the headlamp
cover, on the passenger's side of the engine.
3. Plug it into a normal, grounded 110
-volt AC outlet.
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
11 0
-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.

2-23
DRIVE (D): Use this for normal driving. If you need
more power for passing, and you're:

Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to the next gear.
THIRD (3): This position is not used for normal
driving. It offers more power and lower fuel economy
than DRIVE (D).
Here are some times you might choose THIRD (3)
instead of DRIVE (D):

When driving on hilly, winding roads.

When towing a trailer, so there is less shifting
between gears.

When going down a steep hill.
SECOND (2): Driving in this position gives you more
power than driving in THIRD (3). Use it on hills. It can help
control your speed as you go down steep mountain roads, but
then you would also want to use the brakes off and on.
FIRST (1): This position gives you more power (but
lower fuel economy) than SECOND (2). You can use it
on very steep hills. If the shift lever is put in FIRST (1),
the transmission won't shift into first gear until the
vehicle is going slowly enough.
NOTICE:
If the rear wheels can't rotate, don't try to drive.
This might happen if you were stuck in very deep
sand or mud or you were up against a solid
object. You could damage the transmission.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use the brakes to hold your vehicle
in position on a hill.
Note: When you start your vehicle and the engine
temperature is below 86F (30 C), upshifting of the
transmission will be delayed for about one minute. This
is normal. The engine's catalytic converter is warming
up during this time.
Upshifting and downshifting of the transmission is
automatically modified to prevent undesired shifting when
your vehicle is towing a trailer or when you are driving in
hilly or mountainous terrain. This is also normal.

If you start to drive with the parking brake set, the
BRAKE warning light stays on. See ªBrake System
Warning Lightº in the Index for more information.
To release the parking brake, hold the brake pedal down
with your foot and pull the parking brake lever up until
you can press the end release button. Hold the release
button in as you move the brake lever all the way down.
NOTICE:
Driving with the parking brake on can cause the
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 a hill, see
ªTowing a Trailerº in the Index. This section shows
what to do first to keep the trailer from moving.
Shifting Into PARK (P)
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. 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 ªTowing a
Trailerº in the Index.

2-27 Console Shift Lever
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) like this:

Pull the button on the shift lever handle up and
then push the shift lever all the way toward the
front of your vehicle into PARK (P). Release
the button.

With your right foot still holding the brake pedal
down, set the parking brake.3. Turn the ignition key to LOCK.
4. Remove the ignition key and take it with you. If you
can leave your vehicle with the key in your hand,
your vehicle is in PARK (P).
Leaving Your Vehicle With the
Engine Running
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.

2-68 Traction Control System Warning Light
This warning light will flash
when the system senses a
traction change.
If it stays on, or comes on and stays on steady when
you're driving, there may be a problem with your
traction control system and your vehicle may need
service. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
The traction control system warning light may come on
for the following reasons:

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 the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
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.
Engine Coolant Temperature
Warning Light
This light tells you that the
engine has overheated. If
this light comes on, you
should stop the vehicle and
turn the engine off as soon
as possible.
A warning chime should also sound if this light
comes on.
As a check, the light should come on for a few seconds
when you start the engine. See ªEngine Overheatingº in
the Index.

2-69 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area, the engine is
too hot!
This reading means the same thing as the warning
light
-- the engine coolant has overheated. You should
stop the car and turn the engine off as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
This warning light should
come on for a few seconds
while you are starting the
engine. If the light doesn't
come on, have it repaired.
Your vehicle is equipped with a low coolant level sensor
(switch and float) that is designed to detect when your
vehicle's coolant level drops below the set limit. If the
low coolant level sensor (under the coolant surge tank)
detects that the level drops while the engine is running,
the low coolant indicator will light and remain lit until
the ignition switch is turned off. Check the coolant level
and add coolant as needed. The light should turn off as
soon as the coolant level is at its proper operating range.

4-36 Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) or less to reduce the
possibility of engine and transmission overheating.
Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply the regular brakes, but do not shift into
PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply the parking brake.
5. Release the regular brakes.
