Daytime running light system ●
To make your vehicle more visible to other drivers, the parking lights turn on
automatically (at an increased intensity) whenever the engine is started and the
parking brake is released. Daytime running lights are not designed for use at
night. ●
Compared to turning on th e headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.■
Headlight control sensor
■
Automatic light off system ●
When the headlights are on: The headlights and tail lights turn off 30 seconds
after a door is opened and closed if the “ENGINE START STOP” switch has
been switched to AC CESSORY or OFF mode.●
When only the tail lights are on: The tail lights turn off automatically if the
“ENGINE START STOP” switch is switched to ACCESSORY or OFF mode
and driver’s door is opened.
To turn the lights on again, turn the “ENGINE START STOP” switch to IGNITION
ON mode, or turn the light switch off once and then back to the
or
position. The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

Sensor detection information ●
The sensor’s detection areas are limited to the areas around the vehicle’s front
corner and rear bumpers. ●
Certain vehicle conditions and the su rrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnor-
mal display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensor s in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather
•The area directly under th e bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their
shape, signs and other object s may be judged by the sensor to be closer than they
are.

Advice for driving on slippery roads ●
If you shift the four-wheel drive control sw itch to “L4” and the shift lever to the
“2” range of “S” or “D” (vehicles with paddle shift switches) while driving in
steep off-road areas, the output of the brake can be controlled effectively by the
Active TRAC, which assists the driver to control the driving power of 4 wheels. ●
Use the “1” range of “S” or “D” (vehicles with paddle shift switches) of the shift
lever for maximum power and traction when your wheels get stuck or when
driving down a steep incline.■
The center differential lock indicator light
The indicator light blinks while locking/unlocking the center differential. ■
The center differential lock/unlock switch can be operated when ●
The “ENGINE START STOP” switch is in IGNITION ON mode. ●
The vehicle speed is less than 60 mph (100 km/h).■
Locking/unlocking the center differential ●
When the four-wheel drive control switch is in L4 with the center differential
locked, VSC is automatically turned off. (The center differential lock and VSC
OFF indicator lights come on.) ●
If the operation is not completed, the center differential lock indicator blinks. If
the indicator light does not turn off when unlocking the center differential, drive
straight ahead while accelerating or decelerating, or drive in reverse. ●
If the center differential lock/unlock is not completed within 5 seconds while the
cruise control system is on, ca ncel the cruise control system.

If the low speed four-wheel drive indicator light or the center differential lock
indicator light blinks ●
If the low speed four-wheel drive indicator light continues to blink when using
the four-wheel drive control switch, stop the vehicle completely, move the shift
lever to “N” and operate the switch again. ●
If the shift lever is moved before the low speed four-wheel drive indicator turns
on/off, the transfer mode may not be shifted completely. The transfer mode dis-
engages both the front and rear driveshafts from the powertrain and allows the
vehicle to move regardless of the shift po sition. (At this time, the indicator blinks
and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in “P”.
You or someone else could be seriously injured. You must complete the shifting of
the transfer mode.
To complete the shifting, stop the vehicle completely, return the shift lever to “N”,
and confirm that the shift was completed (the indicator turns on/off). ●
If the engine coolant temperature is too low, the four-wheel drive control system
may not be able to shift. When the engine is warmer operate the switch again.
If the low speed four-wheel drive indicator light or the center differential lock indi-
cator light continues to blink even after attempting the above, there may be a mal-
function in the engine, the brake system or the four-wheel drive system. In this case,
you may not be able to shif t between “H4” and “L4”, and the center differential lock
may not be operable. Have the vehicle inspected by your Lexus dealer immediately.
