2324-3. Operating the lights and wipers
■Conditions to turn the high beams on/off automatically
●When all of the following conditions are met, the high beams will be turned
on automatically (after approximately 1 second):
• The vehicle speed is approximately 21 mph (34 km/h) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.
● If any of the following conditions is met, the high beams will turn off automat-
ically:
• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■ Camera sensor detection information
●The high beams may not be automatically turned off in the following situa-
tions:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear in a faraway lane on a wide road
• When the lights of vehicles ahead are not on
● The high beams may be turned off if a vehicle ahead that is using fog lights
without its headlights turned on is detected.
● House lights, street lights, traffic signals, and illuminated billboards or signs
and other reflective objects may cause the high beams to change to the low
beams, or the low beams to remain on.
● The following factors may affect the amount of time taken for the high
beams to turn on or off:
• The brightness of the headlights, fog lights, and tail lights of vehicles
ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface,
etc.)
• The number of passengers and amount of luggage in the vehicle
● The high beams may turn on or off unexpectedly.
● Bicycles or similar vehicles may not be detected.
2504-5. Using the driving support systems
WARNING
■Limitations of the pre-collision system
● The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.
● Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: →P. 254
• Conditions under which the system may not operate properly: →P. 256
● Do not attempt to test the operation of the pre-collision system yourself, as
the system may not operate properly, possibly leading to an accident.
■ Pre-collision braking
● When the pre-collision braking function is operating, a large amount of
braking force will be applied.
● If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.
● The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.
● In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.
● If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.

◆Installing tire pressure warning valves and transmitters
When replacing the tires or wheels, the tire pressure warning valve
and transmitters must be insta lled to the wheels which will be
installed to the vehicle.
When new tire pressure warning valve and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pr essure warning system must be
initialized. ( →P. 432)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight.
● When the tire inflation pressure is changed such as when the tire
size is changed.
● When rotating the tires.
● Vehicles with a tire inflation pr essure display function: After per-
forming the transmitter ID co de registration procedure. (→P. 432)
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the power switch off.
The initialization procedure cannot be started while the vehicle is
moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( →P. 532)
Make sure to adjust the tire pressu re to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the power switch to ON mode.
Select (4.2-inch display) or (7-inch display) on the multi-
information display using the meter control switches on the steer-
ing wheel. ( →P. 105, 119).
4.2-inch display: Select “Vehicle Settings” and then press .
7-inch display: Select and then press and hold .

◆Registering ID codes
Vehicles without a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. In addition to the set of ti re pressure warning system sensor
ID codes initially registered to th e vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning system sensor ID codes can
be registered at your Toyota deal er. When 2 sets of ID codes have
been registered, either ID code set can be selected.
Vehicles with a tire inflat ion pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. When replacing a tire pressure warning valve and transmitter,
it is necessary to re gister the ID codes.
The ID codes can be registered on (4.2-inch display) or (7-
inch display) of the mu lti-information display.
■Changing the available set of ID codes (vehicles without a tire
inflation pressure display function)
When 2 sets of ID codes are registered, the corresponding ID code
set for the installed wheels can be selected on (4.2-inch display)
or (7-inch display) of the multi-information display. It is not nec-
essary to reregister the ID codes each time the wheels are
changed.
For information regarding changing the registered ID codes for an
ID code set, contact your Toyota dealer.
■How to register the ID codes (vehicles with a tire inflation pres-
sure display function)
Select (4.2-inch display) or (7-inch display) on the multi-
information display using the meter control switches on the steer-
ing wheel. ( →P. 105, 119)

When trouble arises
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extremely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steerin g system warning light comes on
When the light comes on yellow, the assist to the power steering is
restricted. When the light comes on red, the assist to the power steering is
lost and handling operations of the steering wheel become extremely
heavy.
If the steering wheel becomes heavie r than usual when operating, hold
firmly and operate using more force than usual.
■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light co mes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If a tire is flat, change it with the spare tire and have the flat tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
