WARNING
●When driving over roads with pot -
holes or uneven surfaces
■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 stabilit y 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

speed appropriate t o the road condi- tions. As these ar e the systems to
help ensure vehicl e stability and driv-
ing force, do not turn the TRC/VSC/Trailer Sway Control sys -
tems off unle ss 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 capac ity. In addition,
make sure that the tires are inflated to the recommended tire inflation pres -
sure level.
The ABS, TRC and VSC/Trailer Sway Control systems will not function cor -
rectly if different ti res are installed on
the vehicle. Contact any authorized Toyota
retailer or Toyota a uthorized 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 C ontrol system is not able to reduce tr ailer 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 traile r owner’s manual for information on how to tow your
trailer properly.

vehicle control and cause 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
specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains (except
235/55R19 tires)
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehi - cle 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 50 km/h (30 mph),
whichever is lower.
●Avoid driving on bumpy road sur -
faces or over potholes.

Toyota retailer or Toyota authorized
repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and
attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.

4465-6. Driving tips
Perform the following according to
the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro -
zen. 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 sno w that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte -
rior 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.
Accelerate the veh icle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and move the
s hif t le ve r to P w itho u t se tt ing th e
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the park -
ing brake, make sure to block the
wheels.
Failure to do so may be danger -
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
When the parking brake is in automatic
mode, release the parking brake after
shifting the shift lever to P. ( →P.326)
If the vehicle is left parked with
the brakes damp in cold tem -
peratures, there is a possibility of
the brakes freezing.
 If the vehicle is parked without
setting the parking brake, con -
firm that the shift lever cannot be
moved out of P*.
*: The shift lever will be locked if it is
attempted to be shifted from P to any
other position with out depressing the
brake pedal. If the shift lever can be
shifted from P, t here may be a prob-
lem with the shift lock system. Have
the vehicle inspected by any autho -
rized Toyota retailer or Toyota autho -
rized repairer, or any reliable repairer
immediately.

■Heating
●In HV mode, the gasoline engine may
operate in order to extract heat from the engine coolant via the heater.
●In EV mode, heating is done by a heat pump system.
• When the outside t emperature is low
or it is snowing, compared to conven - tional vehicles, heating may be less
effective and warm air may not come
out. • When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte- rior. However, it is not a malfunction.
In this situat ion, the air temperature
from the outlets may not change even though the set tem perature is raised.
• If frost has formed of the outside heat
exchanger, the heating performance will decline. The frost can be removed
from the outside heat exchanger by
operating the Remote Air Conditioning System before driving ( →P.460).
When frosted over, the heating opera -
tion of the Remote Air Conditioning System starts after defrosting.
• When “AUTO” switch is turned on, the
heating is controlle d optimally. There- fore, the set heating performance may
not be achieved even if the fan speed
setting is increased.
Outside heat exchanger
●In the following situations the gasoline
engine may operate in order to extract heat from the engine coolant via the
heater even in EV mode.
• The outside temperature is approxi -
mately -10°C (14°F) or low
