tor flashes to indicate that the
active traction control system
has been engaged.

■ When the rear differential is locked (vehicles with a rear differential
lock system)
The active traction control system is activated only when vehicle speed is
less than 4 mph (6 km/h).
■ Sounds and vibrations caused by the active traction control system
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in the system.
● Vibrations may be felt through the vehicle body and steering. This may
occur when the system is operating.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
At this time, the “A-TRAC” indicator will go off and the “TRAC OFF (TRC
OFF)” indicator will come on. Stop the vehicle in a safe place. (There is no
problem with continuing normal driving.)
The system will be automatically restored after a short time.
CAUTION
■ The active traction control system may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the active traction control system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
