WARNING
●Make sure to use only standard sized tires, such as those that were
installed to the vehicle when it was shipped from the factory. Other-wise, the Advanced Park may not
operate properly. Also, when the tires have been replaced, the dis-played position of the lines or box
displayed on the screen may become incorrect. When replacing the tires, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●As Advanced Park is designed to assist in parking the vehicle in a set parking space, depending on the
condition of the road surface or the vehicle, the distance between the vehicle and a parking space, etc., it
may not be possible to detect a parking space or may not be able to provide assistance to the point the
vehicle is fully parked.
●In situations such as the following, it
may not be possible for the Advanced Park to provide assis-tance to the selected parking spot:
• When the tires are extremely worn or the tire inflation pressure is low
• When carrying a heavy load
• When the vehicle is tilted due to the carried load
• When a heater is installed in the surface of the parking space (road surface freeze prevention heater)
• When the wheels are misaligned, such after a wheels has been sub-
jected to a strong impact
If the vehicle deviates greatly from the
set parking space in any situation
other than the above, have the vehi-
cle inspected by any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

Driving
WARNING
■Stopping distance when the ABS is operating may exceed that of
normal 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 following 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 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 conditions 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 is acti-vated
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 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 systems off unless necessary.
■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 systems will
not function 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.

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 shift 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.
 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
or legitimate tire retailers immedi-
ately.
Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.
