WARNING
■Cautions regarding the use of the system
Do not overly rely on the system, as doing so may lead to an ac cident.
Always drive while checking the safety of the surroundings of t he vehicle.
Depending on the vehicle and road conditions, weather, etc., th e system
may not operate.
The detection capabilities of sensors and radars are limited. A lways drive
while checking the safety of the surroundings of the vehicle.
● The driver is solely responsible for safe driving. Always drive carefully, tak-
ing care to observe your surroundings. The Parking Support Brak e system
is designed to provide support to lessen the severity of collis ions. How-
ever, it may not operate in some situations.
● The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the system has stopped the ve hicle, it is
necessary to depress the brake pedal immediately as brake contr ol will be
canceled after approximately 2 seconds.
● It is extremely dangerous to check the system operations by intentionally
driving the vehicle into the direction of a wall, etc. Never at tempt such
actions.
■ When to disable the Parking Support Brake
In the following situations, disable the Parking Support Brake as the system
may operate even though there is no possibility of a collision.
● When inspecting the vehicle using a chassis roller, chassis dynamo or free
roller
● When loading the vehicle onto a boat, truck or other transport vessel
● If the suspension has been modified or tires of a size other than specified
are installed
● If the front of the vehicle is raised or lowered due to the carried load
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an addi tional trim strip, etc.), bicycle carrier, or
snow plow
● When using automatic car washing devices
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road
● When the tires are not properly inflated
● When the tires are very worn
● When a tire chains, compact spare tire or an emergency tire puncture
repair kit is used

WARNING
■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 wit h 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 attem pt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the TRC/ABS/VSC/Trailer Sway Control is activated
The slip indicator light flashes. Always drive carefully. Reckl ess 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 r oad condi-
tions. As these are the systems to help ensure vehicle stabilit y and driving
force, do not turn the TRC/VSC/Trailer Sway Control systems off unless
necessary.
Trailer Sway Control is part of the VSC system and will not ope rate if VSC is
turned off or experiences a malfunction.
■ Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC, Trailer Sway Control and VSC systems will not fun ction cor-
rectly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer for further information when replacing tires or wheels.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspect the condition of the 12-volt bat-
tery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires*.
Ensure that all tires are the same size and brand, and that cha ins match
the size of the tires.
*: Tire chains cannot be mounted on 18-inch tires or 19-inch tir es.
Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
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 accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior 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.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a ma n-
ner appropriate to the prevailing weather conditions.

17-inch 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
18-inch tires or 19-inch tires
Tire chains cannot be mounted as the space between the tire and
body is too narrow.
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 in stalling
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 instructions provided with the tire chains.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in a loss of vehicle control and ca use 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 spec-
ified for the snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in the vehicle being unable to be d riven 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 surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
■ Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorize d Toyota
retailer or Toyota authorized repairer, or any reliable repaire r or legitimate
tire retailers.
This is because the removal and attachment of snow tires affect s the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not funct ion correctly
when tire chains are fitted.
