Maintenance when Towing a
Trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and hitch.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:

[Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.
If the coolant gauge indicates
over-heating, switch off the air
conditioner and stop the vehicle in a
safe area to cool down the engine.

[ Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)

[ When towing check transmission
fluid more frequently.

[ If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.

Emergency Situations8-28
ONX4080022

[ Use a towing cable or chain less than
16 feet (5 m) long. Attach a white or
red cloth (about 12 inches (30 cm)
wide) in the middle of the cable or
chain for easy visibility.

[ Drive carefully so the towing cable or
chain remains tight during towing.

[ Before towing, check the automatic
transmission for fluid leaks under your
vehicle. If the automatic transmission
fluid is leaking, flatbed equipment or a
towing dolly must be used.
NOTICE
Accelerate or decelerate the vehicle
in a slow and gradual manner while
maintaining tension on the tow rope
or chain to start or drive the vehicle,
otherwise tow hooks and the vehicle
may be damaged.
NOTICE
To avoid damage to your vehicle and
vehicle components when towing:

[Always pull straight ahead when
using the towing hooks. Do not pull
from the side or at a vertical angle.

[ Do not use the towing hooks to pull
a vehicle out of mud, sand or other
conditions from which the vehicle
cannot be driven out under its own
power.

[ Limit the vehicle speed to 10 mph
(15 km/h) and drive less than 1
mile (1.5 km) when towing to avoid
serious damage to the automatic
transmission.

While operating your vehicle:
• Note any changes in the sound of the exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the operation of your transmission occurs,
check the transmission fluid level.
• Check the automatic transmission P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the engine coolant reservoir.
• Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year:
• Check radiator, heater and air conditioning hoses for leaks or
damage.
• Check windshield washer spray and wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlight alignment.
• Check muffler, exhaust pipes, shields and clamps.
• Check the seat belts for wear and function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood hinges.
