CAUTION:
If overheating should occur when towing,
(the temperature gauge reads near the red
zone), taking the following actions may
reduce or eliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the
gear selector in park or neutral and idle
the engine at a higher speed.

C190F01O-AATTrailer or Vehicle Towing Tips1. Before towing, check hitch and safety chain
connections as well as proper operation of
the trailer running lights, brake lights, and
turn signals.
2. Trailer towing requires more fuel than normal
conditions.
3. To maintain engine braking efficiency, do not
tow a trailer with the transaxle in fifth gear
(manual transaxle) or overdrive (automatic
transaxle).
4. Always secure items in the trailer to prevent
load shift while driving.
5. Check the condition and air pressure of all
tires on the trailer and your car. Low tire
pressure can seriously affect the handling.
Also check the spare tire.
6. The vehicle/trailer combination is more af-
fected by crosswind and buffeting.
When being passed by a large vehicle, keep
a constant speed and steer straight ahead.
If there is too much wind buffeting, slow down
to get out of the other vehicle's air turbulence.
7. When parking your car and trailer, especially
on a hill, be sure to follow all the normal
precautions. Turn your front wheel into the
curb, set the parking brake firmly, and put the
transaxle in 1st or Reverse (manual) or Park
(automatic). In addition, place wheel chocks
at each of the trailer's tires.8. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the
trailer brake controller by hand to be sure the
brakes are working. This lets you check
your electrical connection at the same time.
9. During your trip, check occasionally to be
sure that the load is secure, and that the
lights and any trailer brakes are still working.
10.Avoid jerky starts, sudden acceleration or
sudden stops.
11.Avoid sharp turns and rapid lane changes.
12.Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking
efficiency.
13.When going down a hill, shift into a lower gear
and use the engine braking effect.
When ascending a long grade, downshift the
transaxle to a lower gear and reduce speed
to reduce chances of engine overloading
and/or overheating.
14.If you have to stop while going uphill, do not
hold the vehicle in place by pressing on the
accelerator. This can cause the automatic
transaxle to overheat. Use the parking brake
or footbrake.
15.If the transaxle shifts frequently while going
up a hill, shift down one gear.
NOTE:When towing check transaxle fluid more
frequently.

NOTE:
o Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
o Using heavier suspension com-
ponents to get added durability
might not change your weight rat-
ings. Ask your dealer to help you
load your vehicle the right way.
The label will help you decide how much
cargo and installed equipment your
vehicle can carry.
If you carry items inside your vehicle –
like suitcases, tools, packages, or any-
thing else – they more as fast as the
vehicle goes. If you have to stop or turn
quickly, or if there is a crash, the items
will keep going and can cause an injury
if they strikes the driver or a passenger.
!
WARNING:
Items you carry inside your vehicle
can strike and injure people in a
sudden stop or turn, or in a crash.
o Put things in the cargo area of
your vehicle. Try to spread the
weight evenly.
o Never stack items, like suitcases,
inside the vehicle above the tops
of the seats.
o Do not leave an unsecured child
restraint in your vehicle.
o When you carry something inside
the vehicle, secure it.
o Do not drive with a seat folded
down unless necessary.

F060D01A-AATo Fuel Lines, Fuel Hoses and Connec-
tionsCheck the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking
parts immediately.
F060A01A-AAT F060B01A-AAT
o Drive BeltsInspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation and
replace if necessary. Drive belts should be
checked periodically for proper tension and
adjusted as necessary.
F060M01A-AATo Engine Oil and FilterThe engine oil and filter should be changed at the
intervals specified in the maintenance sched-
ule. If the car is being driven in severe condi-
tions, more frequent oil and filter changes are
required.F060C01A-AATo Fuel FilterA clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive amount of foreign matter accumulates in
the fuel tank, the filter may require replacement
more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed by
trained technicians.
F060F01O-AATo Vacuum HosesInspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and
brittle rubber, cracking, tears, cuts, abrasions,
and excessive swelling indicate deterioration.
Particular attention should be paid to examine
those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or mechanical
wear. Inspect all hose connections, such as
clamps and couplings, to make sure they are
secure, and that no leaks are present. Hoses
should be replaced immediately if there is any

WARNING:
The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition. 2. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclock-
wise.
3. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
4. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
5. Fill the radiator with clean demineralized or
distilled water. Continue to add clean dem-
ineralized or distilled water in small quantities
until the fluid level stays up in the radiator
neck.6. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "L" and "F".
7. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
G050D02A-AATTo Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
HJM5034G050D01JM
CAUTION:
Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.

G100B02A-AATTo Check the Manual Transaxle Fluid
LevelWARNING:It is always better to check the transaxle oil
level when the engine is cool or cold. If the
engine is hot, you should exercise great
caution to avoid burning yourself on hot
engine or exhaust parts.Park the car on level ground with the engine off.
1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
2. Use your finger or suitable tool to feel inside
the hole. The oil level should be at its bottom
edge. If it is not, check for leaks before
adding oil. To refill the transaxle or bring the
oil level up,add oil slowly until it reaches the
proper level. Do not overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.
