■Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 479)
● Trailer tires should be inflated according to the trailer manufacturer’s rec-
ommendation.
● All trailer lights work to be legal.
● All lights work each time you connect them.
● The trailer ball is set up at the proper height for the coupler on the t\
railer.
● The vehicle remains level when a loaded or unloaded trailer is hitched.
Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
No matter which class of tow hitch
applies, for a safe trailer hookup, the
trailer ball setup on must be the proper
height for the coupler on the trailer.

When driving
■
When connecting and disconnecting a trailer
Set the electronically modulated air suspension system to LO mode and
push the HEIGHT CONTROL OFF switch to turn off the rear height control
air suspension. (if equipped)
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over 500
miles (800 km).
However, avoid full throttle acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km).
CAUTION
■Trailer towing precautions
●Follow all the instructions described in this section. Failure to do so could
cause an accident resulting in death or serious injury.
● Exceeding the towing capacity, GVWR, GCWR or GAWR can cause an
accident resulting in death or serious injuries.
■ To avoid accident or injury
●Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
● Do not exceed 45 mph (72 km/h) or the posted towing speed limit, which-
ever is lower. As instability (swaying) of the towing vehicle-trailer combina-
tion increases as speed increases, exceeding 45 mph (72 km/h) may
cause loss of control.
● Do not use cruise control when you are towing.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.

Maintenance and care
■
Rear height control air suspension (if equipped)
Do not spray a jet of high-pressure water at the air suspension unit, espe-
cially the air spring, at an extremely close range. This may damage the air
suspension.
■ Coating of rain clearing mirrors
To maintain the rain clearing ability, observe the following instructions.
●Clean the mirror with car shampoo or glass cleaner that does not contain
any silicon or abrasive, and then rinse it throughly with water.
● Expose the mirror to the sunlight 1 or 2 days.
■ To prevent deteriorati on and body corrosion
● Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If you see coal tar or tree sap on the paint surface
• If you see dead insects or insect droppings on the paint
• After driving in an area contaminated with soot, oily smoke, mine dust,
iron powder or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
● If the paint is chipped or scratched, have it repaired immediately.
CAUTION
■Caution about the exhaust pipe
Exhaust gasses 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.
