NOTICE
■Repairing or replacing snow tires
Request repairs of and obtain replacement snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly\
when tire chains are fitted.

Trailer towing (except Canada)
Toyota does not recommend towing a trailer with your vehicle. Toy-
ota also does not recommend the installation of a tow hitch or the
use of a tow hitch carrier of a wheelchair, scooter, bicycle, etc. Your
Toyota is not designed for trailer towing or for the use of tow hitch
mounted carriers.

2-5. Driving information
Trailer towing (Canada)
Your vehicle is designed primarily as a passenger-carrying vehicle,
thus towing a trailer will have an ad verse effect on handling, perfor-
mance, braking, durability, and fu el consumption. For your safety
and the safety of others , do not overload the vehicle or trailer.
Toyota warranties do not apply to damage or malfunction caused by
towing a trailer for commercial purposes.
■ Weight limits
Confirm the total trailer weight, gross vehicle weight, gross axle
weight and trailer tongue load are all within the limits.
■ Gross vehicle weight
The gross vehicle weight must not exceed the Gross Vehicle
Weight Rating (GVWR) indicated on the Certification Label. The
gross vehicle weight is the sum of weights of the unloaded vehi-
cle, driver, passengers, luggage, hitch, and the trailer tongue
load. It also includes the we ight of any special equipment
installed on your vehicle.
■ Gross axle weight
The load on either the front or rear axle resulting from distribu-
tion of the gross vehicle weight on both axles must not exceed
the Gross Axle Weight Rating (GAWR) listed on the Certification
Label.

Trailer tongue load
The trailer cargo load should be distributed so that the tongue
load is 9 to 11% of the total trailer weight, not exceeding the
maximum 70 lb. (32 kg) (Tongue load / Total trailer weight  100
= 9 to 11%)
The total trailer weight and tongue load can be measured with
platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.

Towing a trailerConsult your Toyota dealer for further information about additional
requirements such as a towing kits, etc.
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 345)
● Trailer tires should be inflated according to the trailer manufacturer’s rec-
ommendation.
● All trailer lights work to be legal.
● Confirm all lights work each time you connect them.
● Check that your 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.
● Make sure the trailer cargo is securely loaded.
● Check that your rear view mirrors conform to any federal, state/provincial
or local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
■ Break-in schedule
●Toyota recommends that you do not use a new vehicle or a vehicle with
any new power train components (engine, transmission, differential,
wheel bearings, etc.) to tow a trailer for the first 500 miles (800 km) of
driving.
■ 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
■
To avoid accident or injury
●The total trailer weight (trailer weight plus the weight of cargo) must not
exceed 700 lb. (318 kg)
● Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
■ Hitches
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be rated for towing a
higher weight, the operator must never exceed the maximum weight rating
specified for the trailer hitch.
●If you wish to install a trailer hitch, your Toyota dealer should be consulted.
● Use only a hitch that conforms to the total trailer weight requirement.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coat of grease.
● Remove the trailer hitch whenever you are not towing a trailer to reduce
the possibility of additional damage caused by the hitch if your vehicle is
struck from behind.
■ When towing a trailer
●Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.

160 2-5. Driving information
Trailer towing tipsYour vehicle will handle differently when towing a trailer. The three
main causes of vehicle-trailer ac cidents are driver error, excessive
speed and improper trailer loading. Keep these in mind when towing.
● Before starting out, check the trailer’s light and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and reve rsing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle.
NOTICE
■ When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install the
trailer hitch on the bumper; this may cause body damage.
■ Brakes
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
■ Safety chain
A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should cross
under the trailer tongue to prevent the tongue from dropping to the ground in
the case that it becomes damaged or separated. For the correct safety chain
installation procedure, ask your Toyota dealer.
■ Do not directly splice trailer lights
Directly splicing may damage your vehicle’s electrical system and cause a
malfunction.
