2.4L L4 Engine
In very cold weather, 0
F (
-18
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. On
vehicles with a 2.2L L4 engine, the electrical cord is
located near the engine oil dipstick. On vehicles with
a 2.4L L4 engine, the electrical cord is located in
front of the engine coolant surge tank on the
passenger's side.
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.

2-23 Forward Gears (3-Speed)
DRIVE (D): This position is for normal driving.
SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
NOTICE:
Don't drive in SECOND (2) for more than 25 miles
(40 km), or at speeds over 55 mph (90 km/h), or
you can damage your transaxle. Use DRIVE (D)
as much as possible. Don't shift into SECOND (2)
unless you are going slower than 65 mph
(105 km/h), or you can damage your engine.
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 (1), 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.
Forward Gears (4-Speed)
AUTOMATIC OVERDRIVE (D): This position is for
normal driving with the four
-speed automatic transaxle.
If you need more power for passing, and you're:

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

Going about 35 mph (55 km/h), push your
accelerator all the way down.

2-24
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):

When driving on hilly, winding roads.

When going down a steep hill.
SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
NOTICE:
Don't drive in SECOND (2) for more than 25 miles
(40 km), or at speeds over 55 mph (90 km/h), or you
can damage your transaxle. Use AUTOMATIC
OVERDRIVE (D) or THIRD (3) as much as
possible. Don't shift into SECOND (2) unless you
are going slower than 65 mph (105 km/h), or you can
damage your engine.
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 (1), 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.

2-29 Leaving Your Vehicle With the Engine
Running (Automatic Transaxle Only)
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 PARK (P), hold the
regular brake pedal down. Then, see if you can move the
shift lever away from PARK (P) without first pushing
the button. If you can, it means that the shift lever
wasn't fully locked into PARK (P).
Torque Lock (Automatic Transaxle)
If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver's seat. To find out how, see ªShifting Into
PARK (P)º in the Index.
When you are ready to drive, move the shift lever out
of PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some
of the pressure from the parking pawl in the transaxle,
so you can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
(Automatic Transaxle Only)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is in RUN. See ªAutomatic Transaxleº
in the Index.

2-70 Engine Coolant Temperature Gage
United States Canada
Your vehicle is equipped with one of these gages.
With the ignition in RUN, this gage shows the engine
coolant temperature.If the gage pointer moves into the red area, your
engine is too hot! It means that your engine coolant has
overheated. The CHECK GAGES light should come on
if this condition exists. See ªCheck Gages Lightº later
in this section for more information. If you have been
operating your vehicle under normal conditions, you
should pull off the road, stop your vehicle and turn off
the engine as soon as possible.
In ªProblems on the Road,º this manual shows what
to do. See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on and
stays on, your system is
low on coolant and the
engine may overheat.
See ªEngine Coolantº in the Index and have your
vehicle serviced as soon as you can.

4-40 Driving On Grades
NOTICE:
Do not tow on steep continuous grades exceeding
6 miles (9.6 km). Extended, higher than normal
engine and transaxle temperatures may result
and damage your vehicle. Frequent stops are
very important to allow the engine and transaxle
to cool.
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) to reduce the
possibility of engine and transaxle overheating.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning (if you
have this option) to reduce engine load (see ªEngine
Overheatingº in the Index).
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 your regular brakes, but don't shift into
PARK (P) yet or into gear for a manual transaxle.
When parking uphill, turn your wheels away from
the curb. When parking downhill, turn your wheels
into the curb.
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 apply your parking
brake, and then shift to PARK (P).
5. Release the regular brakes.

4-41 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;

Shift into a gear; and

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, drive belt, cooling system and brake system.
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 this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.
Towing a Trailer (Except Models
with 2.4L L4 Engine and 4
-Speed
Automatic Transaxle)
Do not tow a trailer if your vehicle is:

a convertible model,

equipped with a 2.2L L4 (Code 4) engine or

equipped with a manual transaxle or a three
-speed
automatic transaxle.

Engine Overheating
You will find a coolant temperature gage and a low
coolant warning light on your vehicle's instrument
panel. See ªEngine Coolant Temperature Gageº and
ªLow Coolant Warning Lightº in the Index.
If Steam Is Coming From Your Engine
CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
