Advice for driving on slippery roads ●
If you shift the four-wheel drive control switch 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 wh en your wheels get stuck or when
driving down a steep incline.■
The center differential lock indicator light
The indicator light blinks while lock ing/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, cancel the cruise control system.

a malfunction has occurred in Crawl Control system. ●
Either of the following conditions may occur when the Crawl Control system is
operating. None of these are indicat ors that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.

In inclement weather such as heavy rain, fog, snow or sand storms ●
When your vehicle is skidding such as the VSC system off●
When your vehicle is steeply inclined ●
When the axis of the radar is out of adjustment■
Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-collision system will be automati-
cally disabled. In this case, th e system will not activate even if there is a collision pos-
sibility. ■
