4205-5. Using the driving support systems
WARNING
■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 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/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.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains (except
235/55R19 tires)
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehi- cle being unable to be driven safely, and may cause death or serious
injury.
●Do not drive in excess of the speed
limit specified for the tire chains being used, or 50 km/h (30 mph), whichever is lower.
●Avoid driving on bumpy road sur-faces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden engine braking.
●Slow down sufficiently before enter-ing a curve to ensure that vehicle control is maintained.
●Do not use LTA (Lane Tracing Assist) system (if equipped).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.

5-6. Driving tips
Driving
Perform the following according to
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, outside rear view mir-
rors, windows, 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
parking 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
Park the vehicle and shift the
shift lever 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 park-
ing brake, make sure to block the
wheels. Failure to do so may be
dangerous because it may cause
the vehicle to move unexpect-
edly, possibly leading to an acci-
dent.
When the parking brake is in
automatic mode, release the
parking brake after shifting the
shift lever to P. ( P.321)
If the vehicle is parked without
setting the parking brake, con-
firm that the shift lever 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.

WARNING
■When parking the vehicle
When parking the vehicle without
applying the parking brake, make sure to chock the wheels. If you do not chock the wheels, the vehicle may
move unexpectedly, possibly result- ing in an accident.
4245-6. Driving tips
Vehicles with 225/60R18 tires
Use the correct tire chain size when
mounting the tire chains. Chain size
is regulated for each tire size.
Side chain:
3 mm (0.12 in.) in diameter
10 mm (0.39 in.) in width
30 mm (1.18 in.) in length
Cross chain:
4 mm (0.16 in.) in diameter
14 mm (0.55 in.) in width
25 mm (0.98 in.) in length
Vehicles with 235/55R19 tires
Tire chains cannot be mounted.
Snow tires should be used instead.
Regulations regarding the use of
tire chains vary depending on loca-
tion and type of road. Always check
local regulations before installing
chains.
■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
●Install tire chains on the front tires only. Do not install tire chains on the rear tires.
●Install tire chains on front tires as tightly as possible. Retighten chains
after driving 0.5 - 1.0 km (1/4 - 1/2 mile).
●Install tire chains following the instruc-tions provided with the tire chains.
■Consumption of fuel and electricity
In cold temperatures, resistance of the
parts of a vehicle (transmission, tires, etc.) generally increases, resulting in increase of energy consumption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of
this vehicle is also likely to become worse in cold temperatures.

■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 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 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, pedal almost
touches the floor, vehicle pulls to one
side when braking
●Engine coolant temperature continu-
ally higher than normal (P.187, 193)
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.

7-3. Do-it-yourself maintenance
Maintenance and care
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 “ ” marks, 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.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
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.
4887-3. Do-it-yourself maintenance
Rotate the tires in the order shown.
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 5000 km (3000 miles).
Do not fail to initialize the tire pressure
warning system after tire rotation.
Front
■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 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
When “Adjust Pressure” is dis-
played (Normal Warning)
WARNING
●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 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.
