Before driving
AVALON_U (OM41437U)
CAUTION
●
If the vinyl cover is put on the area where the SRS knee airbag will deploy,
be sure to remove it.
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interf ere with inflation of the airbags.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components shown on P. 91. Doing so can cause the SRS airbags to
malfunction.
● Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbag has deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnish, are damaged or cracked, have them
replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
passenger airbag may not deploy in the event of a collision.

Pull the lever toward you to
turn on the high beams.
Release to turn them off. You can
flash the high beams with the
headlights on or off.
■Daytime running light system (if equipped)
To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the engine is started and the
parking brake is released. Daytime running lights are not designed for use at
night.
■ Headlight control sensor
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight con-
trol system to malfunction.

■ Dripping prevention wiper sweep
After washing and wiping operation several times, the wipers operate one
more time after a short delay to prevent dripping.
However, the last sweep will not happen if the vehicle is traveling above 106
mph (170 km/h).
■ Effects of vehicle speed on wiper operation
Vehicle speed affects the following even when the wipers are not in “AUTO”
mode.
● Intermittent wiper interval ( mode)
● Wiper operation when the washer is being used (delay until drip preven-
tion wiper sweep occurs)
With low speed mode, wiper operation will be switched from low speed to

■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir.
■ In extremely hot or cold weather (v ehicles equipped with the raindrop
detection windshield wipers)
Even if the wiper lever is in “AUTO” mode, the system will switch to intermit-
tent operations when the system malfunctions.
However, when the windshield gets extremely hot (at more than 194°F
[90°C]) or extremely cold (at less than 14°F [-10°C]), the wipers do not oper-
ate even if the wiper lever is in “AUTO” mode.
■ Customization that can be co nfigured at Toyota dealer

Cruising in vehicle-to-veh icle distance control mode
This mode employs a laser radar sensor to detect the presence of
vehicles within 400 ft. (120 m) ahead and to judge the distance
between your vehicle and those vehicles.
Note that vehicle-to-vehicle distance will close when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance switch.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, in the same lane, the
system automatically decelerates your vehicle. When a greater reduction
in vehicle speed is necessary, the system applies the brakes. A warning
tone warns you when the system cannot decelerate sufficiently to prevent
your vehicle from closing on the vehicle ahead.
