tor flashes to indicate that the
active traction control system
has been engaged.
CTH24AS047
■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” indicator
will come on. Stop the vehicle in a safe place. (There is no problem with con-
tinuing normal driving.)
The system will be automatically restored after a short time.
CAUTION
■The active traction control system m ay 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.

CTH24AS047
■If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
At this time, the “AUTO LSD” indicator will flash and the “TRAC OFF” indica-
tor 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
■ To avoid an accident
● Do not use the AUTO LSD system in conditions other when wheel spin-
ning occurs in a ditch or rough surfaces.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

Using the rear differential lock system
Before using the rear differential lock system:
Stop the vehicle, shift the shift lever to N and shift the front-
wheel drive control lever into L4 to see if this is sufficient. If
this has no effect, additionally use the rear differential lock
system.
Be sure the wheels have stopped spinning.
Press the rear differential lock switch.
Gently depress the accelerator pedal.
After the rear differential is locked, the indicator will come on.
Unlock the rear differential as soon as the vehicle moves.
To unlock the rear differential, press the switch again.
■ Locking the rear differential
The following systems do not operate when the rear differential is locked. It
is normal operation for the ABS warni ng light and VSC off indicator to be on
at this time.
•ABS
• Multi Terrain ABS
• Brake assist system
•VSC
• Hill-start assist control
■ The rear differential lock is disengaged when
The front-wheel drive control lever is shifted to H2 or H4.
Never forget to turn off the switch after using this feature.
■ After unlocking the rear differential
Check that the indicator goes off.
■ If the rear differential lock indicator flashes rapidly
There may be a malfunction in the rear differential lock system. Have the
vehicle inspected by your Toyota dealer immediately.

■System malfunction
In case of a system malfunction, the following may occur:
● The downhill assist control system indicator flashes in a situation other
than those listed above.
● The downhill assist control system indicator does not come on when the
engine switch is turned to the “ON” position (vehicles without a smart key
system) or the “ENGINE START STOP” switch is turned to IGNITION ON
mode (vehicles with a smart key system).
Have your vehicle inspected by your Toyota dealer.
CAUTION
■ Conditions which may affect the downhill assist control system opera-
tion
● Do not rely too heavily on the downhill assist control system. On extremely
steep inclines, icy surfaces or muddy roads, the vehicle may slip and the
system may not be able to maintain the constant low vehicle speed of
about 3 mph (5 km/h), leading to an accident causing death or serious
injury.
● Do not shift the shift lever to R while driving forward, or to D while driving
backward. Doing so may cause the wheels to lock up, leading to an acci-
dent causing death or serious injury. In addition, excessive stress will be
applied to the automatic transmission, possibly resulting in damage.
