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 rmly set. And, if you leave the
vehicle with the engine running, it could
overheat and even catch re. You or
others could be injured. Do not leave your
vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. After you have 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 rst pushing the
button. If you can, it means that the shift lever was
not fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you do not 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 nd
it difficult to pull the shift lever out of PARK (P).
This is called “torque lock.” To prevent torque lock,
set the parking brake and then shift into PARK (P)
properly before you leave the driver’s seat.
To nd out how, seeShifting Into Park (P)
(Automatic Transaxle) on page 116.
When you are ready to drive, move the shift
lever out of PARK (P)beforeyou 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, then you will be able to pull
the shift lever out of PARK (P).

Engine Coolant Temperature Gage
This gage measures the
temperature of the
vehicle’s engine coolant.
If the pointer moves into the shaded area, your
engine is too hot, the CHK GAGE message
will appear and a chime will sound to alert you to
the engine coolant temperature gage. See
Check Gage Message on page 184for more
information. If you have been operating your
vehicle under normal driving conditions, you should
pull off the road and stop your vehicle, be sure
the air conditioning is off, let the engine idle for a
few minutes, then turn off the engine.On vehicles with the 2.2L engine, under severe
conditions – hot ambient temperature, steep
grades and towing – your vehicle may experience
more transaxle shifting to avoid engine coolant
overheating. This is temporary and normal under
these conditions. This does not require engine
or transaxle service.
If your engine control system detects a failure in
the engine coolant temperature circuit, the
malfunction indicator lamp light will come on. The
coolant gage may read all the way hot or cold.
The engine cooling fan will be turned on to protect
the engine and transaxle. SeeMalfunction
Indicator Lamp on page 174for more information.
Notice:Driving with the engine coolant
temperature gage indicator in the shaded area
could cause your vehicle to overheat. Your
vehicle could be damaged, and it might not be
covered by your warranty. Never drive with
the engine coolant temperature gage indicator
in the shaded area.

You will need a well-charged battery to restart the
vehicle, and possibly for signaling later on with
your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start
the engine again and repeat this only when you
feel really uncomfortable from the cold. But do it as
little as possible. Preserve the fuel as long as
you can. To help keep warm, you can get out of
the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
In order to free your vehicle when it is stuck, you
will need to spin the wheels, but you do not
want to spin your wheels too fast. The method
known as rocking can help you get out when you
are stuck, but you must use caution.
If your vehicle has the Enhanced Traction System
(ETS), the ETS can often help to free a stuck
vehicle. SeeEnhanced Traction System (ETS) on
page 226. If the stuck condition is too severe
for the ETS to free the vehicle, turn the ETS off
and use the rocking method.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or
others could be injured. And, the
transaxle or other parts of the vehicle can
overheat. That could cause an engine
compartment re or other damage. When
you are stuck, spin the wheels as little as
possible. Do not spin the wheels above
35 mph (55 km/h) as shown on the
speedometer.
Notice:Spinning the wheels can destroy parts
of your vehicle as well as the tires. If you
spin the wheels too fast while shifting
the transaxle back and forth, you can destroy
the transaxle. SeeRocking Your Vehicle to
Get It Out on page 250.
For information about using tire chains on your
vehicle, seeTire Chains on page 348.

Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could be
damaged. Avoid making very sharp turns
while trailering.
When you are turning with a trailer, make wider
turns than normal. Do this so your trailer will
not strike soft shoulders, curbs, road signs, trees
or other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring.
See your retailer if you need information.
The arrows on your instrument panel will ash
whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also
ash, telling other drivers you are about to turn,
change lanes or stop.When towing a trailer, the arrows on your
instrument panel will ash for turns even if the bulbs
on the trailer are burned out. Thus, you may think
drivers behind you are seeing your signal when
they are not. It’s important to check occasionally to
be sure the trailer bulbs are still working.
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
do not 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 the engine and the transaxle
overheating. If your engine does overheat,
seeEngine Overheating on page 297.

Maintenance When Trailer Towing
Your vehicle will need service more often when
you are pulling a trailer. SeeScheduled
Maintenance on page 391for more information.
Things that are especially important in trailer
operation are automatic transaxle uid (don’t
overll), engine oil, axle lubricant, drive belt,
cooling system and brake system. Each of these
is covered in this manual, and the Index will
help you nd them quickly. If you are 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. SeeEngine
Overheating on page 297.
Changing a Tire When Trailer Towing
If you get a at tire while towing a trailer, be
sure to secure the trailer and disconnect it from
the vehicle before changing the tire.

Manual Transaxle Fluid
It is not necessary to check the transaxle uid level.
A transaxle uid leak is the only reason for uid
loss. If a leak occurs, take the vehicle to your
retailer’s service department and have it repaired
as soon as possible. SeeRecommended Fluids
and Lubricants on page 402for the proper uid
to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives uid from the brake master
cylinder reservoir.
SeeBrakes on page 308for more information.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 297.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to
−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core, or
radiator corrosion. In addition, the engine
coolant may require changing sooner, at the
rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.

What to Use
Use a mixture of one-half clean, drinkable water
and one-half DEX-COOL®coolant which will
not damage aluminum parts. If you use this coolant
mixture, you do not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant
mixture, your engine could overheat and be
badly damaged. The repair cost would not be
covered by your warranty. Too much water
in the mixture can freeze and crack the engine,
radiator, heater core, and other parts.
If you have to add coolant more than four times a
year, have your retailer check your cooling system.
Notice:If you use extra inhibitors and/or
additives in your vehicle’s cooling system, you
could damage your vehicle. Use only the
proper mixture of the engine coolant listed in
this manual for the cooling system. See
Recommended Fluids and Lubricants on
page 402for more information.
