■Situations in which the system may
not operate properly
●In certain situations, such as the fol-
lowing, a detectable object may not be detected by the front sensors, and the system may not operate properly:
• When a detectable object is approaching your vehicle• When your vehicle or a detectable
object is wandering • When a detectable object makes an abrupt maneuver (such as sudden
swerving, acceleration or decelera- tion)• When suddenly approaching a detect-
able object • When the detectable object is near a wall, fence, guardrail, manhole cover,
steel plate on the road surface, or another vehicle• When there is a structure above a
detectable object • When part of a detectable object is hidden by another object (large lug-
gage, umbrella, guardrail, etc.) • When multiple detectable objects are overlapping
• When a bright light, such as the sun, is reflecting off of a detectable object• When a detectable object is white and
looks extremely bright • When the color or brightness of a detectable object causes it to blend in
with its surroundings • When a detectable object cuts in front of or suddenly emerges in front of
your vehicle • When approaching a vehicle which is diagonal
• If a vehicle ahead is a child sized bicy- cle, is carrying a large load, is carrying an extra passenger, or has an unusual
shape (bicycles equipped with a child seat, tandem bicycles, etc.)• If a pedestrian or bicycle is shorter
than approximately 1 m (3.2 ft.) or taller than approximately 2 m (6.5 ft.).• When the silhouette of a pedestrian or
bicycle is unclear (such as when they are wearing a raincoat, long skirt, etc.)• When a pedestrian or bicycle is bend-
ing forward or squatting
• When a pedestrian or bicycle is mov- ing at high speed• When a pedestrian is pushing a
stroller, wheelchair, bicycle or other vehicle• When a detectable object blends in
with the surrounding area, such as when it is dim (at dawn or dusk) or dark (at night or in a tunnel)
• When the vehicle has not been driven for a certain amount of time after the EV system was started
• While turning left/right or a few sec- onds after turning left/right• While driving around a curve and a
few seconds after driving around a curve• When turning left/right and an oncom-
ing vehicle is driving in a lane 3 or more lanes from the vehicle• When turning left/right and the direc-
tion of the vehicle differs greatly from the direction traffic flows in the oncoming lane

WARNING
●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 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, VSC and Trailer
Sway Control systems will not func- tion 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.
■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 Control system is
not able to reduce trailer 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 trailer owner’s manual for information on how to tow your trailer properly.
■If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead. Do not try to control trailer swaying by turning
the steering wheel.
●Begin releasing the accelerator
pedal immediately but very gradu- ally to reduce speed. Do not increase speed. Do not apply vehi-
cle brakes. If you make no extreme correction with the steering or brakes, your
vehicle and trailer should stabilize. ( P.237)
■Secondary Collision Brake
Do not rely solely upon the Secondary Collision Brake. This system is
designed to help reduce the possibil- ity of further damage due to a second-ary collision, however, that effect
changes according to various condi- tions. Overly relying on the system may result in death or serious injury.

the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
 To ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte-
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
 Remove any snow or mud from
the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Turn automatic mode of the park-
ing brake off. Otherwise, the
parking brake may freeze and
not be able to be released auto-
matically.
Also, avoid using the following as the
parking brake may operate automati-
cally, even if automatic mode is off.
• Brake hold system
• Remote parking function
 Park the vehicle and shift the
shift position to P without setting
the parking brake. The parking
brake may freeze up, preventing
it from being released. If the
vehicle is parked without setting
the parking brake, make sure to
block the wheels.
Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
When the parking brake is in
automatic mode, release the
parking brake after shifting the
shift position to P. ( P.255)
 If the vehicle is parked without
setting the parking brake, con-
firm that the shift position cannot
be moved out of P.
 If the vehicle is left parked with
the brakes damp in cold tem-
peratures, there is a possibility of
the brakes freezing.
Use the correct tire chain size when
mounting the tire chains. Chain size

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.
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 any autho- rized Toyota retailer or Toyota autho-rized 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.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow
tires is lost.
■Replacing tires
Your vehicle may not be equipped with the following tools and jack for replacing
a tire. In this case, when replacing tires, purchase tools and jack. Tools and jack
can be purchased at any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

Maintenance and care
Rotate the tires in the order shown.
Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
Do not fail to initialize the tire pressure
warning system after tire rotation.
■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 tire pressure warning sys-tem after checking that the tire pressure
is properly adjusted.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so may cause damage
to parts of the drivetrain 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.
●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 unexpected damage to the tire.
NOTICE
■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.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.

also take a few minutes to display the
tire inflation pressure after inflation pressure has been adjusted.
●Tire inflation pressure changes with temperature.The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■Situations in which the tire pres-sure warning system may not oper-
ate properly
●In the following cases, the tire pres-
sure warning system may not operate properly.• If non-genuine Toyota wheels are
used. • A tire has been replaced with a tire that is not an OE (Original Equipment)
tire. • A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped. • If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheels without tire pressure warning valves and transmitters are used.• If the ID code on the tire pressure
warning valves and transmitters is not registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-play, airport or other facility that gen-
erates strong radio waves or electrical noise• When carrying a portable radio, cellu-
lar phone, cordless phone or other wireless communication device
If tire position information is not correctly
displayed due to the radio wave condi-
tions, the display may be corrected by
driving and changing the radio wave
conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves
and transmitters are installed, new ID
codes must be registered in the tire
pressure warning computer and the tire
pressure warning system must be ini-
tialized. ( P.484)
■When replacing the tires and wheels
If the ID code of the tire pressure warn-
ing valve and transmitter is not regis- tered, the tire pressure warning system will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and
stays on to indicate a system malfunc- tion.
