When driving
CAUTION
●
If the vehicle is in a poorly ventilated area, stop the hybrid system. In a
closed area, such as a garage, exhaust gases may collect and enter the
vehicle. This may lead to death or a serious health hazard.
● The exhaust system should be checked occasionally. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise,
be sure to have the vehicle inspected and repaired by your Toyota dealer.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
■ When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, you may accidentally move the
shift lever or depress the accelerator pedal, which could cause an accident
or fire due to hybrid system overheating. Additionally, if the vehicle is parked
in a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
■ When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.
● If the electronically controlled brake system does not operate, do not fol-
low other vehicles closely and avoid downhills or sharp turns that require
braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
● The brake system consists of 3 individual hydraulic systems: If one of the
systems fails, the others will still operate. In this case, the brake pedal
should be depressed more firmly than usual and braking distance
becomes longer. If this happens, do not continue to drive the vehicle.
■ If the vehicle becomes stuck or bogged
Do not spin the wheels recklessly when any of the tires is up in the air, or
stuck in sand or mud etc. This may damage the drive system components or
propel the vehicle forward (or in another direction) and cause an accident.

172 2-1. Driving procedures
CAUTION
■If you hear a squealing or scrapin g noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible.
The rotor damage can result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or that of the brake discs are exceeded.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually press the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds.
● The vehicle will behave abnormally.
Replace a flat tire with a new one. ( P. 505)
NOTICE
■When driving the vehicle
Do not use the accelerator pedal or depress accelerator and brake pedals
together to hold the vehicle on a hill.
■ When parking the vehicle
Always put the shift lever in P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is acci-
dentally depressed.
■ Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a
long time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.

When driving
Driving assist systems
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)
Maintains drive power and prevents the four wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Prevents the vehicle from rolling backwards when starting on incline or
slippery slope.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
■VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, VSC, TRAC and
EPS systems.
Maintains vehicle stability when swerving on slippery road surfaces by
controlling the brakes, hybrid system output, and the movement of the
four wheels.

216 2-4. Using other driving systems
When the VSC/TRAC/hill-start assist control systems are operating
If the vehicle is in danger of slip-
ping, rolling backwards when
starting on an incline, or the four
wheels spin, the indicator flashes
to indicate that the VSC/TRAC/
hill-start assist control systems
have been engaged.
●ABS: The slip indicator light
flashes when ABS is operat-
ing.
● VSC: A buzzer (intermittent)
sounds to indicate that VSC is
operating.
● Hill-start assist control: When
the system is operating, the
stop lights and high mounted
stoplight turn on.
■Sounds and vibrations caused by the ABS, TRAC, VSC and brake
assist
●A sound may be heard from the engine compartment when the hybrid
system is started or just after the vehicle begins to move. This sound
does not indicate that a malfunction has occurred in any of these sys-
tems.
● 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.

When driving
■Hill-start assist control operating conditions
●The system will operate in the following situations:
• The shift lever is in a position other than P
• The parking brake is not applied
• The accelerator pedal is not depressed
To engage the system, bring the vehicle to a complete stop and then further
depress the brake pedal. A buzzer beeps once to indicate that hill-start
assist control is ready.
The system operates for a period of approximately 2 seconds after the brake
pedal is released.
● Hill-start assist control will not operate when “Check VSC system” is dis-
played on the multi-information display.
■ If the buzzer does not sound or the indicator does not flash
Slightly reduce the pressure on the brake pedal and then fully depress it
again.
■ Automatic cancellation of hill-start assist control
In the following situations, the buzzer will beep twice and hill-start assist con-
trol will be canceled.
●No attempt is made to drive the vehicle within approximately 2 seconds
of releasing the brake pedal
● The shift lever is moved to P
● The parking brake is applied
● The brake pedal is re-applied.
■ EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
■ Reduced effectiveness of EPS
The effectiveness of EPS 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 hybrid system off.
The system should return to normal within 10 minutes.

When driving
CAUTION
■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS and VSC systems will not function correctly if different tires are fit-
ted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the VDIM, and may cause the system to malfunction.

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 the road. Do not take unnecessary risks by driving
in dangerous places.
● Do not grip the steering wheel spokes when driving off-road. A bad bump
could jerk the wheel and injure your hands. Keep both hands and espe-
cially your thumbs on the outside of the rim.
● Always check your brakes for effectiveness immediately after driving in
sand, mud, water or snow.
● After driving through tall grass, mud, rock, sand, rivers, etc., 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 or in rugged terrain, 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 and chassis.
