WARNING
■Before using LDA system
Do not rely solely upon the LDA system. LDA is not a system which auto-
matically drives the vehicle or reduces 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 always paying careful attention to the sur-
rounding conditions and operate the steering wheel to correct the path of
the vehicle. Also, make sure to take adequate breaks when fatigued, such
as from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
■ To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.
■ Situations unsuitable for LDA system
Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, resulting in
death or serious injury.
● A spare tire, tire chains, etc., are equipped.
● When the tires have been excessively worn, or when the tire inflation pres-
sure is low.
● Tires which differ by structure, manufacturer, brand or tread pattern are
used.
● Objects or patterns that could be mistaken for white (yellow) lines are
present on the side of the road (guardrails, curbs, reflective poles, etc.).
● Vehicle is driven on a snow-covered road.
● White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
● Asphalt repair marks, white (yellow) line marks, etc., are present due to
road repair.
● Vehicle is driven in a temporary lane or restricted lane due to construction
work.
● Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.
● Vehicle is driven in traffic lanes other than on highways and freeways.
● Vehicle is driven in a construction zone.
● Vehicle is towing a trailer or another vehicle.

The fixed guide lines are very far out of alignment
• The vehicle is tilted (there is a
heavy load on the vehicle, tire
pressure is low due to a tire punc-
ture, etc.)
• The vehicle is used on an incline.If this happens due to these causes,
it does not indicate a malfunction.
Back up while visually checking the
vehicle's surroundings.
The camera position is out of align-
ment.Have the vehicle inspected by your
Toyota dealer.
WARNING
■ When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to check visually
behind and all around the vehicle before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes.

EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● Vehicles without a smart key system: When the engine switch is turned to
the “LOCK” position
Vehicles with a smart key system: When the engine switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine of\
f. The
EPS system should return to normal within 10 minutes.
WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ 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 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 potholes or uneven surfaces
