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.

4265-6. Driving tips
cautions to ensure your driving
enjoyment and to help prevent the
closure of areas to off-road vehi-
cles:
 Drive your vehicle only in areas
where off-road vehicles are per-
mitted to travel.
 Respect private property. Get
owner’s permission before enter-
ing 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
travel delayed to prevent dam-
age to roads.
WARNING
■Off-road driving precautions
Always observe the following precau- tions to minimize the risk of death, serious injury or damage to your vehi-
cle:
●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 especially your thumbs on the outside of the rim.
●Always check your brakes for effec-tiveness 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 break-
down 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 the water damage
Take all necessary safety measures to ensure that water damage to the hybrid battery (traction battery),
hybrid system or other components does not occur.
●Water entering the engine compart-
ment may cause severe damage to the hybrid system.
●Water entering the hybrid transmis-sion will cause deterioration in transmission quality. The malfunc-
tion indicator may come on, and the vehicle may not be drivable.
●Water can wash the grease from wheel bearings, causing rusting and premature failure, and may
also enter the hybrid transaxle case, reducing the gear oil’s lubri-cating qualities.

8-2. Steps to take in an emergency
When trouble arises
WARNING
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediately
after the vehicle has been driven. After the vehicle has been driven,
the wheels and the area around the brakes may be extremely hot. Touching these areas with hands,
feet or other body parts may result in burns.
●Connect the valve and hose securely with the tire installed on the vehicle. If the hose is not prop-
erly connected to the valve, air leakage may occur as sealant may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk
that the hose will move abruptly due to air pressure.
●After inflation of the tire has com-pleted, the sealant may splatter when the hose is disconnected or
some 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 opera-tion 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 oper-
ated for a long period of time. Do not operate the repair kit continu-ously for more than 40 minutes.
●Parts of the repair kit become hot during operation. Be careful han-
dling the repair kit during and after operation. Do not touch the metal part connecting the bottle and the
compressor. 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 oper- ating properly.
■Driving to spread the liquid seal-ant 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 low speed. Be especially careful when
turning and cornering.
