WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
■Situations unsuitable for LTA system
In the following situations, use the LTA switch to turn the system off. Fail-ure to do so may lead to an accident,
resulting in death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or restricted lane due to con-
struction work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc., are
equipped.
●When the tires have been exces-
sively worn, or when the tire infla- tion pressure is low.
●When your vehicle is towing a trailer or during emergency towing.
■Preventing LTA system malfunc-tions and operations performed by mistake
●Do not modify the headlights or place stickers, etc., on the surface of the lights.
●Do not modify the suspension, etc. If the suspension, etc., needs to be
replaced, contact 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

NOTICE
• 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.
■To prevent damage to the wind-shield wiper arms
When lifting the wiper arms away from the windshield, pull the driver side wiper arm upward first, and
repeat for the passenger side. When returning the wipers to their original position, do so from the passenger
side first.
■When using an automatic car
wash (vehicles with rain-sensing windshield wipers)
Set the wiper switch to the off posi-
tion. 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
●Vehicles with rear view monitor sys-
tem: When washing the vehicle, do not spray the camera or its sur-rounding area directly with a high
pressure washer. Shock applied from high pressure water may cause the device to not operate
normally.
●Do not spray water directly on the
radar which is equipped behind the emblem. Otherwise it may cause the device to be damaged.
●Do not bring the nozzle tip close to boots (rubber or resin manufac-
tured cover), connectors or the fol- lowing parts. The parts may be damaged if they come into contact
with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 30 cm (11.9 in.) away from the vehi-
cles 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.
●Do not spray the lower part of the windshield continuously. If water enters the air conditioning system
intake located near the lower part of the windshield, the air conditioning system may not operate correctly.
