WARNING
ODo not use the system in the following situations, as the system may be
unable to correctly assist you in reaching the target parking s pot and may
lead to an unexpected accident.
• In an area that is not a parking lot
• A parking lot that is not paved and has no parking space lines , such as
a sand or gravel parking lot
• A parking lot that has a slope or undulations in the road
• A frozen, snow-covered or slippery road
• The asphalt is melting due to hot weather
• There is an obstacle between the vehicle and the target parkin g spot
• Using tire chains
O Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact any aut horized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
O The system may not be able position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc. located on o ne side of
the vehicle
• There are road heaters installed in the parking lot to prevent the road
surface from freezing.
In any other situations when the set position and vehicle posit ion greatly
differ, have the vehicle inspected by any authorized Toyota ret ailer or
Toyota authorized repairer, or any reliable repairer.
O Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when depar ting from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use t his function
when departing from a parallel parking spot. In the event that the steering
control operates, either turn the system off using the S-IPA sw itch or oper-
ate the steering wheel to stop the control.
O If exit parallel parking assist mode is mistakenly used in the following situ-
ations, the vehicle may make contact with an obstacle.
The departure function is operated in a direction where an obst acle is
present, but the obstacle is not detected by the side sensors ( situations
such as when the vehicle is directly beside a pole).

WARNING
QThe ABS does not operate effectively when
O The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
O The vehicle hydroplanes while driving at high speed on wet or slick roads.
Q 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 dista nce. Always
maintain a safe distance from the vehicle in front of you, espe cially in the
following situations:
O When driving on dirt, gravel or snow-covered roads
O When driving with tire chains
O When driving over bumps in the road
O When driving over roads with potholes or uneven surfaces
Q TRC/VSC may not operate effectively when
Directional control and power may not be achievable while drivi ng on slip-
pery road surfaces, even if the TRC/VSC system is operating. Dr ive the
vehicle carefully in conditions where stability and power may b e lost.
Q Hill-start assist control does not operate effectively when
O Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered wit h ice.
O Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attem pt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
Q When the TRC/ABS/VSC is activated
The slip indicator light flashes. Always drive carefully. Reckl ess driving may

QTire chain installation
Observe the following precautions when installing and removing chains:
OInstall and remove tire chains in a safe location.
OInstall tire chains on the front tires only. Do not install tire chains on the rear
tires.
OInstall tire chains on front tires as tightly as possible. Retighten chains after
driving 0.5 - 1.0 km (1/4 - 1/2 mile).
OInstall tire chains following the instructions provided with the tire chains.
QConsumption of fuel and electricity
In cold temperatures, resistance of the parts of a vehicle (transmission, tires,
etc.) generally increases, resulting in increase of energy consumption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of this vehicle is also likely to become
worse in cold temperatures.
