WARNING
●When driving over roads with pot -
holes or uneven surfaces
■TRC/VSC may not operate effec -
tively when
Directional control and power may not be achievable while driving on slip -
pery road surfaces , even if the
TRC/VSC system is operating.
Drive the vehicle carefully in condi - tions where stabilit y and power may
be lost.
■Active Cornering Assist does not
operate effectively when
●Do not overly rely on Active Corner - ing Assist. Active Cornering Assist
may not operate effectively when
accelerating down slopes or driving on slippery road surfaces.
●When Active Cornering Assist fre - quently operates, Active Cornering
Assist may temporarily stop operat -
ing to ensure prop er operation of the brakes, TRC and VSC.
■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not
attempt to use hill-start assist con -
trol to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
■When the TRC/ABS/VSC/Trailer
Sway Control is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicat or light flashes.
■When the TRC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a
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.

■Does your vehicle need repairs?
Be on the alert for changes in perfor - mance and sounds, a nd visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-
ever, water dripping from the air con - ditioning system after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monox -
ide leak. Drive with the windows open
and have the exhau st system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire
wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy
feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one
side when braking
●Engine coolant temperature continu -
ally higher than normal ( →P.174)
If you notice any of these clues, take
your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repair er as soon as possi-
ble.
Your vehicle may need adjustment or repair.

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.

■When rotating the tires
Make sure that the power switch is OFF. If the tires are rotated while the power
switch is in ON, the tire position informa -
tion will not be updated.
If this accidentally occurs, either turn the
power switch to OFF and then to ON, or
initialize the system after checking that
the tire pressure is properly adjusted.
Your vehicle is equi pped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla -
tion pressure before serious prob -
lems arise.
The tire pressure warning system
of this vehicle adopts a 2-type
warning system
 When “Adjust Pressure” is dis-
played (Normal Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire
inflation pressure becomes low due to
natural air leakage or outside tempera-
ture. (Ways of coping: →P.575, 624)
When “Immediately Check tire
when Safe” is displayed (Emer -
gency Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire
inflation pressure becomes low sud -
denly due to a blowout. (Ways of cop -
ing: →P.575, 582, 593)
However, the system may not be able
to detect sudden tire ruptures (bursting,
etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa -
tion display.
The unit can be changed.
■How to change the unit
1 Park the vehicle in a safe place
and turn the power switch off.
Changing the unit cannot be performed while the vehicle is moving.
2 Turn the power switch to ON.
