■ GCWR (Gross Combination Weight Rating)
The maximum allowable gross
combination weight. The gross
combination weight is the sum of
the total vehicle weight (including
the occupants, cargo and any
optional equipment installed on
the vehicle) and the weight of the
trailer being towed (including the
cargo in the trailer).
■ GVWR (Gross Vehicle Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehicle
weight is the total weight of the
vehicle. When towing a trailer, it
is the sum of the vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
tongue weight.

272 2-5. Driving information
■GAWR (Gross Axle Weight Rating)
The maximum allowable gross
axle weight. The gross axle
weight is the load placed on
each axle (front and rear).
■ TWR (Trailer Weight Rating)
The maximum allowable gross
trailer weight. The gross trailer
weight is the sum of the trailer
weight and the weight of the
cargo in the trailer.
TWR is calculated assuming
base vehicle with one driver, one
front passenger, towing package
(if available), hitch and hitch sys-
tems (if required).
Additional optional equipment,
passengers and cargo in the vehi-
cle will reduce the trailer weight
rating so as not to exceed
GCWR, GVWR and GAWR.
If the gross trailer weight exceeds
3000 lb. (1360 kg), it is recom-
mended to use a trailer with 2 or
more axles.

Trailer Tongue Weight● A recommended tongue weight varies in accordance with the types
of trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must
be loaded by referring to the following instructions.
• Tongue Weight
The gross trailer weight should be distributed so that the tongue
weight is 9% to 11%. (Tongue we ight /Gross trailer weight x 100
= 9% to 11%)
Gross trailer weight
Tongue weight
If using a weight distributing hitch when towing, return the front
axle to the same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the
front fender height above th e front axle before connection.
Adjust weight distributing hitch torque until front fender is
returned to the same height as before connection.
The gross trailer weight, gross axle weight and tongue weight
can be measured with platform scales found at a highway
weighing station, building supply company, trucking company,
junk yard, etc.

Hitch
Trailer hitch assemblies have different weight capacities. Toyota rec-
ommends the use of Toyota hitch/bracket for your vehicle. For details,
contact your Toyota dealer.
● If you wish to install a trailer hitch, contact your Toyota dealer.
● Use only a hitch that conforms to the gross trailer weight require-
ment of your vehicle.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coating of grease.
● Remove the trailer hitch whenever you are not towing a trailer.
After removing the hitch, seal any mounting hole in the vehicle
body to prevent entry of any substances into the vehicle.

Selecting trailer ballUse the correct trailer ball for your application. Trailer ball load rating
Matches or exceeds the gross
trailer weight rating of the trailer.
Ball diameter
Matches the size of the trailer
coupler. Most couplers are
stamped with the required trailer
ball size.
Shank length
Protrudes beyond the bottom of
the lock washer and nut by at
least 2 threads.

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. 521)
● Trailer tires are inflated according to the trailer manufacturer’s recom-
mendation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on the trai\
ler.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper tongue
weight, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to a ll applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
● Depress TOW/HAUL button (if equipped)
■ AVS (adaptive variable suspension system) (if equipped)
The suspension can be switched for improvement in driveability. ( →P. 238)
No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.

■Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential or wheel bearing), Toyota rec-
ommends that you do not tow a trailer until the vehicle has been driven \
for
over 500 miles (800 km).
After the vehicle has been driven for ov er 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the vehicle at a
speed of less than 50 mph (80 km/h) when towing a trailer, and avoid full
throttle acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Owner’s Warranty Information Booklet”
or “Scheduled Maintenance Guide/Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km) of trailer towing.
■ If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradually to reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. (if enabled, Trailer Sway Control can also help to
stabilize the vehicle and trailer.)
● After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not overloaded after occupants get in.
