brake parts are extremely cold,
extremely hot, or wet
• If the vehicle is not properly main-
tained (brakes or tires are excessively
worn, improper tire inflation pressure,
etc.)
• When the vehicle is being driven on a
gravel road or other slippery surface
• When the road surface has deep
wheel tracks
• When driving on a hill road
• When driving on a road that has
inclines to the left or right
■If VSC is disabled
●If VSC is disabled (→P.270), the pre-
collision brake assist and pre-collision
braking functions are also disabled.
●The PCS warning light will turn on and
“VSC Turned OFF Pre-Collision Brake
System Unavailable” will be displayed
on the multi-information display.
*: If equipped
LTA (Lane Tracing
Assist)
*
When driving on highways and
freeways with white (yellow)
lane lines, this function alerts
the driver when the vehicle
might depart from its lane or
course
* and provides assis-
tance by operating the steering
wheel to keep the vehicle in its
lane or course
*. Furthermore,
the system provides steering
assistance when dynamic
radar cruise control is operat-
ing to keep the vehicle in its
lane.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects pre-
ceding vehicles using the front
camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,
soil, or a curb

WARNING
●The vehicle hydroplanes while driv- ing at high speed on wet or slick
roads.
■Stopping distance when the ABS
is operating may exceed that of normal conditions
The ABS is not designed to shorten
the vehicle’s stopping distance. Always maintain a safe distance from the vehicle in front of you, especially
in the following situations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●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 conditions where stability 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 proper 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/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 indicator light flashes.
■When the TRC/VSC/Trailer Sway
Control systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driv-ing force, do not turn the
TRC/VSC/Trailer Sway Control sys- tems off unless 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 capacity. In addition, make sure that the tires are inflated to
the recommended tire inflation pres- sure level.The ABS, TRC Trailer Sway Control
and VSC systems will not function correctly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer for further information
when replacing tires or wheels.

Maintenance and care
request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor-
mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine misses (misfire), 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 exhaust 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 or clutch pedal
(vehicles with a manual transmission),
pedal almost touches the floor, vehicle
pulls to one side when braking
●Engine coolant temperature continu-
ally higher than normal (→P.86, 90)
If you notice any of these clues, take
your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment
or repair.

6-3. Do-it-yourself maintenance
Check if the treadwear indicators
are showing on the tires. Also
check the tires for uneven wear,
such as excessive wear on one
side of the tread.
Check the spare tire condition and
pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is
shown by a “TWI” or “ ” mark, etc., 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 years old must be
checked by a qualified technician even if
it has seldom or never been used, or
damage is not obvious.
■Low profile tires (16 and 17-inch
tires)
Generally, low profile tires will wear
more rapidly and tire grip performance
will be reduced on snowy and/or icy
roads when compared to standard tires.
Be sure to use snow tires on snowy
and/or icy roads and drive carefully at a
speed appropriate for road and weather
conditions.
■If the tread on snow tires wears
down below 4 mm (0.16 in.)
The effectiveness of the tires as snow
tires is lost.
■Checking the tire valves
When replacing the tires, check the tire
valves for deformation, cracks, and
other damage.
Tires
Replace or rotate tires in
accordance with maintenance
schedules and treadwear.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.Failure to do so may cause damage
to parts of the drive train as well as dangerous handling characteristics, 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.
NOTICE
■Low profile tires (16 and 17-inch
tires)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention to the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement, curbs and other road hazards. Fail-ure to do so may lead to severe tire
and wheel damage.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
■Driving on rough roads
Take particular care when driving on roads with loose surfaces 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.
Tire rotation

6-3. Do-it-yourself maintenance
Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
When rotating front and rear tires which
have different tire inflation pressures,
do not fail to initialize the tire pressure
warning system after tire rotation.
Your vehicle is equipped 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.
zWhen “Adjust Pressure” is dis-
played (Normal Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is an unknown level of low tire
pressure with the appearance of the tire
due to natural air leakage as well as the
pressure lowering due to changes in
the pressure according to the outside
temperature. (Ways of coping: →P.375,
417)
zWhen “Immediately Check tire
when Safe” is displayed (Emer-
gency Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is a known level of low tire pres-sure with the appearance of the tire due
to pressure suddenly lowering. (Ways
of coping: →P.379, 389)
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
1Park the vehicle in a safe place
and turn the engine switch off.
Changing the unit cannot be performed
while the vehicle is moving.
2Turn the engine switch to ON.
3Press / (vertical display)
