NOTICE
n Repairing or replacing snow tires
Request repairs of and obtain replac ement snow tires from Toyota deal−
ers or legitimate tire retailers.
This is because the removal and atta
chment of snow tires affects the
operation of the tire pressure warning valves and transmitters.
n Fitting tire chains
The tire pressure warning valves and transmitters may not function cor−
rectly when tire chains are fitted.

236 2−5. Driving information
nBefore towing
Check that the following conditions are met:
lThe vehicle’s tires are properly inflated.
lTrailer tires are inflated according to the trailer manufacturer ’s recom−
mendation.
lAll trailer lights work.
lAll lights work each time you connect them.
lThe trailer ball is set up at the proper height for the coupler on the trailer.
lThe 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.
lThe trailer cargo is securely loaded.
lThe 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.
nBreakin schedule
Toyota recommends that you do not use a new vehicle or a vehicle with any
new power train components (engine, transmission, differential, wheel bear−
ings, etc.) to tow a trailer for the first 500 miles (800 km) of driving.
nMaintenance
lIf 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”.)
lRetighten the fixing bolts of the towing ball after approximately 600 miles
(1000 km) of trailer towing.

CAUTION
nHitches
lLubricate the hitch ball with a light coat of grease.
lIf using a weight distributing hitch when towing, keep your vehicle level
with the ground.
nWhen towing a trailer
lIf the gross trailer weight exceeds 1000 lb. (453 kg), trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli−
cable federal and state/provincial regulations.
lNever tap into your vehicle’s hydraulic system, as this will lower the vehi−
cle’s braking effectiveness.
lNever 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.
NOTICE
nWhen installing a trailer hitch
lUse only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
lDo not use axle−mounted hitches, as they can cause damage to the axle
housing, wheel bearings, wheels or tires.
nSafety 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.
nDo not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle’s electrical system
and cause a malfunction.

Maintenance and care
Tires
Replace or rotate tires in accordance with maintenance sched
ules and treadwear.
nChecking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear
indicators is shown by the
“TWI” or “
” marks, etc.,
molded on the sidewall of
each tire.
Check spare tire condition
and inflation pressure if not
rotated.
nTire rotation
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, Toyota recom−
mends that tire rotation is
carried out at the same inter−
val as tire inspection.
Do not fail to initialize the tire
pressure warning system
after tire rotation.
nThe tire pressure warning system
Your Toyota is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low
tire inflation pressure before
serious problems arise. (

Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warn ing valve and transmitter ID codes
must be registered in the tire pr essure warning computer and tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyota
dealer. (

Maintenance and care
Initializing the tire pressure warning system
nThe tire pressure warning system must be initialized in the fol
lowing circumstances:
lWhen rotating the tires on vehicles differing with front and rear
tire inflation pressures.
lWhen changing the tire inflation pressure by changing traveling
speed or load weight, etc.
lWhen changing the tire size.
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the pressure benchmark.
n
How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the “ENGINE START
STOP” switch to OFF mode.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla−
tion pressure level. (
P. 502)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti
re pressure warning system will
operate based on this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode.

Maintenance and care
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
n When to replace your vehicle’s tires
Tires should be replaced if:
lYou have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
lA tire goes flat repeatedly or c annot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
n Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure warning system will not work properly. After
driving for about 20 minutes, the ti
re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
n Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
n If the treadwears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
