■
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.
If all wheels spin, the slip indica-
tor flashes to indicate that the
active traction control system
has been engaged.
