speed appropriate t o the road condi- tions. As these ar e the systems to
help ensure vehicl e stability and driv-
ing force, do not turn the TRC/VSC/Trailer Sway Control sys -
tems off unle ss necessary.
Trailer Sway Control is part of the VSC system and will not operate if
VSC is turned off or experiences a
malfunction.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern
and total load capac ity. In addition,
make sure that the tires are inflated to the recommended tire inflation pres -
sure level.
The ABS, TRC and VSC/Trailer Sway Control systems will not function cor -
rectly if different ti res are installed on
the vehicle. Contact any authorized Toyota
retailer or Toyota a uthorized repairer,
or any reliable repairer for further information when replacing tires or
wheels.
■Handling of tires and the suspen -
sion
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may
cause a system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway C ontrol system is not able to reduce tr ailer sway in all
situations. Depending on many fac -
tors such as the conditions of the
vehicle, trailer, road surface and driv - ing environment, the Trailer Sway
Control system may not be effective.
Refer to your traile r owner’s manual for information on how to tow your
trailer properly.

molded into the sidewall of each tire.
Replace the tires if the treadwear indi -
cators are showing on a tire.
■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating inter -
nal damage.
●A tire goes flat repeatedly or cannot
be properly repaired due to the size or location of a cut or other damage.
If you are not sure, consult with any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■Tire life
Any tire over 6 y ears old must be checked by a qualified technician even if
it has seldom or never been used or
damage is not obvious.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of t he tires as snow
tires is lost.
Rotate the tires in the order shown.
To equalize tire wear and help extend
tire life, Toyota re commends that tire
rotation is carried out approximately
WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents. Failure to do so may cause damage
to parts of the driv e train as well as
dangerous handling c haracteristics, which may lead to an accident result -
ing in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and
snow tires.
●Do not use tires that have been
used on another vehicle.
Do not use tires if you do not know how they were used previously.
●Vehicles with compact spare tire: Do not tow if your vehicle has a
compact spare tire installed.
●Vehicles with emergency tire punc -
ture repair kit: Do not tow anything
if a tire that has been repaired using the emergency tire puncture repair
kit is installed. The load on the tire
may cause unexpec ted damage to the tire.
NOTICE
■Driving on rough roads
Take particular care when driving on
roads with loose sur faces or potholes. These conditions may cause losses in
tire inflation pressure, reducing the
cushioning ability of the tires. In addi - tion, driving on rough roads may
cause damage to the tires them -
selves, as well as the vehicle’s wheels and body.
■If tire inflation pressure of each tire becomes low while driving
Do not continue drivi ng, or your tires
and/or wheels may be ruined.
