tems will automatically re-enable them.
Vehicles with smart key system
Turning the “POWER” switch OFF after turning off the TRAC and VSC
systems will automatically re-enable them.
■ Automatic TRAC reactivation
If only the TRAC system is turned off, the TRAC system will turn on when
vehicle speed increases.
■ Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on
even when vehicle speed increases.
■ 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.

242 2-4. Using other driving systems
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Reduced effectiveness of 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 hybrid
off. The EPS system should return to normal within 10 minutes.
■ If the slip indicator comes on...
It may indicate a malfunction in the VSC and TRAC. Contact your Toyota
dealer.
CAUTION
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle's stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven roads

When driving
CAUTION
■TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When the VSC 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 TRAC and VSC are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to help ensure vehicle stability and driving force,
do not turn off TRAC and VSC unless necessary.
■ 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.

Hill-start assist control
■Hill-start assist control operating conditions
The system operates 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.
■ Hill-start assist control
●While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
● Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
● If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicl e to roll backward) and then firmly
depress it again. If the system still does not operate, check that the oper-
ating conditions explained above have been met.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on an incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

■Hill-start assist control buzzer
●When hill-start assist control is activated, the buzzer will sound once.
● In the following situations, hill-start assist control will be canceled and the
buzzer will sound twice.
• 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 depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.
■ If the slip indicator comes on...
It may indicate a malfunction in the system. Contact your Toyota dealer.
CAUTION
■Hill-start assist control
●Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on extremely steep inclines or roads covered in 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 control to hold the vehicle on an incline for an extended
period of time, as doing so may lead to an accident.

Utility vehicle precautions
Utility vehicle feature● Specific design characteristics give it a higher center of gravity
than ordinary passenger cars. This vehicle design feature causes
this type of vehicle to be more likel y to rollover. And, utility vehicles
have a significantly higher rollover rate than other types of vehi-
cles.
● It is not designed for cornering at the same speeds as ordinary
passenger cars any more than lo w-slung sports cars designed to
perform satisfactorily under off-road conditions. Therefore, sharp
turns at excessive speeds may cause rollover.
This vehicle belongs to the utility vehicle class, which has higher
ground clearance and narrower tread in relation to the height of its
center of gravity.

Utility vehicle precautions
Always observe the following precautions to minimize the risk of serious per-
sonal injury or damage to your vehicle:
●In a rollover crash, an unbelted person is significantly more likely to die
than a person wearing a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is moving.
● Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or
vehicle rollover causing death or serious injury.
● Loading cargo on the roof luggage carrier will make the center of the vehi-
cle gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden
braking or abrupt maneuvers, otherwise it may result in loss of control or
vehicle rollover due to failure to operate this vehicle correctly.
● Always slow down in gusty crosswinds. Because of its profile and higher
center of gravity, your vehicle is more sensitive to side winds than an ordi-
nary passenger car. Slowing down will allow you to have better control.
● Do not drive horizontally across steep slopes. Driving straight up or
straight down is preferred. Your vehicle (or any similar off-road vehicle)
can tip over sideways much more easily than forward or backward.

248 2-5. Driving information
Off-road drivingYour vehicle is not designed to be driven off-road. However, in the
event that off-road driving cannot be avoided, please observe the fol-
lowing precautions to help avoid the areas prohibited to vehicles.
● Drive your vehicle only in areas wh ere off-road vehicles are permit-
ted to travel.
● Respect private property. Get owner’s permission before entering
private property.
● Do not enter areas that are closed. Honor gates, barriers and signs
that restrict travel.
● Stay on established roads. When conditions are wet, driving tech-
niques should be changed or trav el delayed to prevent damage to
roads.
● Avoid driving on very steep, sl ippery roads and other surfaces,
such as sand, where the tires are liable to lose traction. Your vehi-
cle may not perform as well as conventional AWD on-road vehicles
on these surfaces.
■ Additional information for off-road driving
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining to driving your vehicle off-road,
consult the following organizations.
● State and Local Parks and Recreation Departments
● State Motor Vehicle Bureau
● Recreational Vehicle Clubs
● U.S. Forest Service and Bureau of Land Management

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.

NOTICE
■To prevent water damage
Take all necessary safety measures to ensure that water damage to the
hybrid battery, hybrid system or other components does not occur.
●Water entering the engine compartment may cause severe damage to the
hybrid system. Water entering the interior may cause the hybrid battery
stowed under the rear seats to short circuit.
● Water entering the hybrid transaxle w ill cause deterioration in transmission
quality. The malfunction indicator may come on, and the vehicle may not
be drivable.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the transaxle case, reducing the gear
oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
●Sand and mud that has accumulate d in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.
