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 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

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 and VSC/Trailer Sway Control systems will not function cor-rectly 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.
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 snow 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 vehicle 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
shift lever to P without setting the
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 without depressing the
brake pedal. If the shift lever can be
shifted from P, there 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.

■Precaution regarding the rear bumper with Blind Spot Monitor
(if equipped)
If the paint of the rear bumper is chipped or scratched, the system may
malfunction. If this occurs, consult any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
NOTICE
■To prevent paint deterioration and corrosion on the body and
components (aluminum wheels, etc.)
●Wash the vehicle immediately in
the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, insect droppings or
bird droppings are present on the paint surface
• After driving in an area contami- nated with soot, oily smoke, mine dust, iron powder or chemical sub-
stances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gas- oline are spilled on the paint sur-face
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corrod-ing, remove any dirt and store in a
place with low humidity when stor- ing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard
brush. This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■When using an automatic car wash
Set the wiper switch to off position.
If the wiper switch is in “AUTO”, the wipers may operate and the wiper blades may be damaged.
■When using a high pressure car wash
●When washing the vehicle, do not let water from the high-pressure washer directly hit the camera (if
equipped) or the area around the camera. Due to the shock from the high pressure water, it is possible
that the device may not operate normally.
●Do not bring the nozzle tip close to boots (rubber or resin manufac-tured cover), or connectors or the
following parts. The parts may be damaged if they come into contact with high-pres-
sure water.
• Traction battery
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 30 cm (11.9 in.) away from the vehi-
cle body. Otherwise resin section, such as moldings and bumpers, may be deformed and damaged.
Also, do not continuously hold the nozzle in the same place.
