Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. The arrows on your instrument
panel will flash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash 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 stiil working.
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) to reduce the
possibility of engine and transaxle overheating.
P; ‘ting on Hills
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) for an automatic transaxle or into a
gear for a manual transaxle, yet. 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
1/:!?ee!s.
3. When the 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 shift into PARK (P) for an
automatic transaxle or
REVERSE (R) for a manual
transaxle.
5. Release the regular brakes.

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
Engine Overheating on
page
5-26.

The engine
oil dipstick handle is yellow. The dipstick on
the
2.2L L4 ECOTEC engine is located at the front of
the engine compartment. The dipstick on the
3400
V6 engine is located at the front of the engine, behind
the fan. See
Engine Compartment Overview on
page
5-12 for more information on location.
Turn
off the engine and give the oil several minutes to
drain back into the oil pan.
If you don’t, the oil
dipstick might not show the actual level.

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid
loss.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked by
your dealer or service center when you have your
oil
changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
Notice: We recommend you use only fluid labeled
DEXRQN@-Ill, because fluid with that label
is
made especially for your automatic transaxle.
Damage caused
by fluid other than DEXRON@-Ill is
not covered by your new vehicle warranty.
Manual Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid
loss.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked by
your dealer or service center when you have your oil
changed. See
Part D: Recommended Fluids and
Lubricants
on page 6-15 for the proper fluid to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir is
filled with hydraulic clutch fluid.
It is not necessary to regularly check clutch fluid unless
you suspect there is a leak in the system. Adding
fluid won’t correct a leak.
A fluid
loss in this system could indicate a problem.
Have the system inspected and repaired.

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
covered by your warranty.

If No Steam Is Coming From Your
Engine
An overheat warning, along with a low coolant light, can
indicate a serious problem. See
Low Coolant Warning
Light
on page 3-31.
If you get an engine overheat warning with no low
coolant light, but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a
little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
engine idle.

The windshield washer
fluid reservoir is located in
the engine compartment
towards the front of
the vehicle. Notice:
Open the cap with the washer symbol on it. Add washer
fluid until the tank is full. When
using concentrated washer fluid, follow
the manufacturer’s instructions for adding
water.
Don’t mix water with ready-to-use washer fluid.
Water can cause
the solution to freeze and
damage your washer fluid tank and other parts
of the washer system.
Also, water doesn’t
clean as well as washer fluid.
Fill your washer fluid tank only three-quarters
full when
it’s very cold. This allows for
expansion if freezing occurs, which could damage the tank if
it is completely full.
Don’t use engine coolant (antifreeze)
in your
windshield washer.
It can damage your
washer system and paint.

Windshield Wiper Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See “Wiper Blade
Check in
At Least Twice a Year on page 6-10 for more
information.
Replacement blades come
in different types and are
removed
in different ways. Here’s how to remove
the wiper blade:
1. Pull the windshield wiper arm away from the
windshield.
2. Push the release lever and slide the wiper assembly
toward the driver’s side of the vehicle.
3. Install a new blade by reversing Steps 1 and 2.
For the proper type and size, see Capacities and
Specifications
on page 5-86.

Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See
When It Is Time
for New Tires on page
5-56 and Wheel Replacement
on page
5-59 for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See “Part A: Scheduled
Maintenance Services,” in Section 6, for scheduled
rotation intervals. Don’t include the
compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown
on the Tire-Loading
Information label.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and
Specifications on page
5-86.
Rust or dirt on a wheel, or or parts to
which
it is fastened, can make wheel nuts
become loose after a time. The wheel could
come
off and cause an accident. When you
change a wheel, remove any rust
or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do
this; but be sure to use a
