QTire information
O Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi)
greater than the recommended value when towing. ( P. 639)
O Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the values recommended by the manufac-
turer of your trailer.
Q Tr a i l e r l i g h ts
Check that the turn signal lights and stoplights are operating correctly every
time you hitch up the trailer. Direct ly wiring up to your vehicle may damage
the electrical system and stop the lights from functioning correctly.
Q Break-in schedule
Toyota recommends that vehicles fitted with new power train components
should not be used for towing trailers for the first 800 km (500 miles).
Q Safety checks before towing
O Check that the maximum load limit for the towing hitch/bracket and hitch ball
is not exceeded. Bear in mind that the coupling weight of the trailer will add
to the load exerted on the vehicle. Also make sure that the total load exerted
on the vehicle is within the range of the weight limits. ( P. 216)
O Ensure that the trailer load is secure.
O Supplementary outside rear view mirrors should be added to the vehicle if
the traffic behind cannot be clearly seen with standard mirrors. Adjust the
extending arms of these mirrors on both sides of the vehicle so that they
always provide maximum visibility of the road behind.
Q Maintenance
O Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight burden placed on the vehicle compared to
normal driving.
O Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).

cautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather
Q Brake pads and calipers
Rust may form if the vehicle is parked with wet brake pads or disc rotors,
causing them to stick, or causing noi ses or vibrations. Before parking the
vehicle after it is washed, drive slowly and apply the brakes several times to
dry the parts.
Q Bumpers
Do not scrub with abrasive cleaners.
Q Plated portions
If dirt cannot be removed, clean the parts as follows:
O Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.
O Wipe the surface with a dry, soft cloth to remove any remaining moisture.
O To remove oily deposits, use alcohol wet wipes or a similar product.
WARNING
QWhen washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
Q Precautions regarding the exhaust pipe
Exhaust gases cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has
cooled sufficiently, as touching a hot exhaust pipe can cause burns.

QCaring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
Q Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
Q Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
WARNING
Q Water in the vehicle
O Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch
fire.
