■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
To tow a trailer safely, use extreme care and drive the vehicle in accordance
with the trailer’s characteristics and operating conditions.
The vehicle stability and braking performance are affected by trailer stability,
brake setting and performance, and the hitch.
Follow all the instructions described in this section. Failure to do so could
cause an accident resulting in death or serious injury.
■ Weight limit precautions
●The gross trailer weight must never exceed towing capacity. ( P. 251)
● The gross combination weight must never exceed the GCWR. ( P. 251)
● Exceeding the towing capacity, GVWR, GCWR or GAWR can cause an
accident resulting in death or serious injuries.
●The gross vehicle weight must never
exceed the GVWR indicated the Certifi-
cation Label.
● The gross axle weight on each axle
must never exceed the GAWR indi-
cated the Certification Label.

Tongue load or king pin weight
●A recommended tongue load or king pin weight varies in accordance with
the types of trailers or towing as described below.
● In order to ensure the recommended values shown below, the trailer must
be loaded by referring to the following instructions.
1. Conventional Towing The trailer cargo load should be distributed so that the tongue load is 9 to
11% of the gross trailer weight, not exceeding the following.
(Tongue load/Gross trailer weight x 100 = 9 to 11%)
If the gross trailer weight is over 2000 lbs. (907 kg), it is necessary to use a
sway control device with sufficient capacity.
If the gross trailer weight is over 5000 lbs.(2268 kg), it is necessary to use
a weight distributing hitch with sufficient capacity.
If using a weight distributing hitch when towing, keep your vehicle level
with the ground.
2. Fifth wheel Towing The king pin weight is 15 to 25% of the Gross Trailer weight.
(King pin weight/Gross trailer weight x 100 = 15 to 25%)
CrewMax models: Current fifth wheel trailer designs are not compatible
with short bed.

3Snow tiresFor driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( P. 246)
■Initializing the tire pr essure warning system
Initialize the tires with the tire inflati on pressure adjusted to the specified
level.
■If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire in flation pressure to the speci-
fied level and initialize the tire pressure warning system again.
■When the initialization of the tire pressure warning system has
failed
Initialization can be completed in se veral minutes. However, in the fol-
lowing cases, the settings have not been recorded and the system will
not operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.
●When operating the tire pressure warning reset switch, the tire pres-
sure warning light does not flash 3 times.
●After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute and then stays on after driving for about
20 minutes.
■Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.

Maintenance and care
Wheels
■When replacing wheels
The wheels of your Toyota are equipped with tire pressure warning
valves and transmitters (except for spare tire) that allow the tire pressure
warning system to provide advanced warning in the event of a loss in tire
inflation pressure. Whenever wheels are replaced, the tire pressure
warning valves and transmitte rs must be installed. (P. 495)
If a wheel is bent, cracked or heavily corroded, it should be
replaced.
Otherwise, the tire may separate from the wheel or cause loss of
handling control.
■ Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and offset.
Replacement wheels are available at your Toyota dealer.
Toyota does not recommend using:
●Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Wheel precautions
●Use only Toyota wheel nuts and wrench designed for use with
your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 100 miles (160 km).
● Be careful not to damage the aluminum wheels when using
tire chains.
● Use only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.
