Driving assist systems
When the TRAC/VSC/ABS systems are operatingThe slip indicator light will flash
while the TRAC/VSC/ABS sys-
tems are operating.
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
■TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
■Hill-start assist control
P. 256
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

■Sounds and vibrations caused by the ABS, brake assist, TRAC, and
VSC systems
●A sound may be heard from the motor compartment when the EV system
is started or just after the vehicle begins to move, if the brake pedal is
depressed forcefully or repeatedly, or 1 - 2 minutes after the EV system is
stopped. This sound does not indicate that a malfunction has occurred in
any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
●When the “POWER” switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling
will not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the EV sys-
tem off. The EPS system should return to normal within 10 minutes.
■ If the slip indicator comes on...
It may indicate a malfunction in the TRAC, VSC and ABS. Contact your
Toyota dealer.

Off-road driving precautions
Always observe the following precautions to minimize the risk of serious per-
sonal injury or damage to your vehicle:
●Drive carefully when off-road driving is unavoidable. Do not take unneces-
sary risks by driving in dangerous places.
● Do not grip the steering wheel spokes when off-road driving is unavoid-
able. A bad bump could jerk the wheel and injure your hands. Keep both
hands and especially your thumbs on the outside of the rim.
● Always check your brakes for effectiveness immediately after driving in
sand, mud, water or snow.
● When it is unavoidable to drive through tall grass, mud, rock, sand, etc.,
take care not to damage the traction batteries equipped under the floor.
After driving through such terrain, check that there is no grass, bush,
paper, rags, stone, sand, etc. adhering or trapped on the underbody. Clear
off any such matter from the underbody. If the vehicle is used with these
materials trapped or adhering to the underbody, a breakdown or fire could
occur.
● When driving off-road is unavoidable, do not drive at excessive speeds,
jump, make sharp turns, strike objects, etc. This may cause loss of control
or vehicle rollover causing death or serious injury. You are also risking
expensive damage to your vehicle’s suspension, chassis, drive unit or the
traction batteries.

When driving
CAUTION
■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 size specified.
●Maintain the recommended level of air pressure.
●Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
●Use snow tires on all, not just some wheels.
●Do not mix tires of different makes, models, tread patterns or tread-
wear.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle 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 30 mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden regenerative braking.
●Slow down sufficiently before entering a curve to ensure that vehicle
control is maintained.

CAUTION
■When the electric power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
■ If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a
loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.
● If the tire pressure warning light comes on even after tire inflation pressure
adjustment, it is probable that you have a flat tire. Check the tires. If the
tire is flat, temporarily repair it with liquid sealants and have the flat tire
repaired or replaced by the nearest Toyota dealer as soon as possible.
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■
If a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.

5-2. Steps to take in an emergency
CAUTION
●After inflation of the tire has comp
leted, the sealant may splatter when
the hose is disconnected or so me air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not
followed, the sealant may spray out.
●Keep back from the tire while it is being repaired, as there is a chance
of it bursting while the repair ope ration is being performed. If you
notice any cracks or deformation of the tire, turn off the compressor
switch and stop the repair operation immediately.
●The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 35 minutes.
●Parts of the repair kit become hot during operation. Be careful when
handling the repair kit during and after operation. Do not touch the
metal part around the connecting area between the bottle and com-
pressor. It will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than
the one indicated. If the sticker is attached to an area where an SRS
airbag is located, such as the pad of the steering wheel, it may prevent
the SRS airbag from operating properly.
■Driving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
●Drive the vehicle carefully at a lo w speed. Be especially careful when
turning and cornering.
●If the vehicle does not drive straight or you feel a pull through the
steering wheel, stop the vehicle and check the following.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 19 psi (130
kPa, 1.3 kgf/cm
2 or bar) or less, the tire may be severely dam-
aged.

5-2. Steps to take in an emergency
If your vehicle has to be stopped in an emergency
CAUTION
■If the EV system has to be turned off while driving
Power assist for the steering wheel will be lost, making the steering wheel
heavier to turn. Decelerate as much as possible before turning off the EV
system.
Only in an emergency, such as if it becomes impossible to stop the
vehicle in the normal way, stop the vehicle using the following pro-
cedure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Shift the shift position to N.
If the shift position is changed to N After slowing down, stop the vehi cle in a safe place by the
road.
Stop the EV system.
If the shift position cannot be changed to N Keep depressing the brake pedal with both feet to reduce
vehicle speed as much as possible.
To stop the EV system, press
and hold the “POWER” switch
for 2 consecutive seconds or
more, or press it briefly 3
times or more in succession.
