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 (if equipped)
■ Automatic light off system
●When the light switch is in the
or position with the tail
lights on: The tail lights turn off after driver’s door is opened if the engine
switch has been turned to the “ACC” or “LOCK” position.
● When the light switch is in the or position with the head-

■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 565)
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 sys-
tem to malfunction.

■The windshield wipers and washer can be operated when
The engine switch is in the “ON” position.
■ 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.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.
■ When a nozzle is blocked
Do not try to clear it with a pin or other object. The nozzle will be damaged.

■Automatic cruise control cancellation
The set speed is automatically canceled in any of the following situations.
●Actual vehicle speed falls more than 10 mph (16 km/h) below the preset
vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below 25 mph (40 km/h).
● VSC is activated.
■ If the cruise control indicator light flashes
Turn the “ON-OFF” button off once, and then reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels
immediately after being activated, there may be a malfunction in the cruise
control system. Have the vehicle inspected by your Toyota dealer.
CAUTION
■To avoid operating the cruise control by mistake
Keep the “ON-OFF” button off when not in use.
■ Situations unsuitable for cruise control
Do not use cruise control in any of the following situations.
Doing so may result in control of the vehicle being lost and could cause seri-
ous or fatal accident.
●In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep hills

Dynamic laser cruise control (if equipped)
Dynamic laser cruise control supple ments conventional cruise con-
trol with a vehicle-to-vehicle distan ce control. In the vehicle-to-vehi-
cle distance control mode, the vehicle automatically accelerates or
decelerates in order to maintain a set following distance from vehi-
cles ahead.

■Changing the vehicle -to-vehicle distance
Each pull of the switch toward
you changes the vehicle-to-
vehicle distance.
Long
Medium
Short
The vehicle-to-vehicle distance
is automatically set to the long
mode when the engine switch
is turned to the “ON” position.
A mark will be displayed to
indicate the presence of the
vehicle if a vehicle is running
ahead of you.

202 2-4. Using other driving systems
Driving in vehicle-to-vehicle 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 distanc e will close when traveling on long
downhill slopes.
Example of constant speed cruising (when there are no vehicles
ahead):
When set to 62 mph (100 km/h)
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 driv-
ing slower than the set speed):
When fixed speed cruising is set at 62 mph (100 km/h) and the
vehicle ahead is driving at 50 mph (80 km/h)
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.
