If the engine is turned off and restarted

The AUTO LSD system and the indicators are automatically turned off.

■

Reactivation of the VSC system linked to vehicle speed

When the AUTO LSD system is turned on, the VSC, TRAC and Trailer Sway
Control systems will turn on automatically if vehicle speed increase.

■

If the brake system overheats

The system will cease operation and a buzzer will alert the driver. At this time,
the “AUTO LSD” indicator will flash and the “TRAC OFF” indicator will come

WARNING

■

To avoid an accident

Failure to do so, a much greater steering effort and more careful cornering
control will be required.

●

Do not use the AUTO LSD system in conditions other than when one of
the drive wheels spinning occurs in a ditch or rough surface.

●

Do not drive with the AUTO LSD system continuously turned on.

NOTICE

■

Activating while driving

Do not activate the AUTO LSD system if the wheel is slipping.
Stop the slipping or spinning before activating.

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 warning 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 or switch 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.

WARNING

■

To avoid an accident

●

Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or rugged surface. Large steering effort
and careful cornering control will be required.

●

Do not lock the rear differential until the wheels have stopped spinning.
Otherwise, the vehicle may move in an unexpected direction when the dif-
ferential lock is engaged, resulting in an accident. This may also lead to
possible damage to rear differential lock component parts.

●

Do not drive over 5 mph (8 km/h) when the rear differential is locked.

●

Do not keep driving with the rear differential lock switch on.

Downhill assist control system



: If equipped

The downhill assist control system helps to prevent excessive
speed on steep downhill slopes. The system will operate when
the vehicle is traveling under 15 mph (25 km/h) with the acceler-
ator and brake pedals released and the transfer mode is in L4
(part-time 4WD models) or L4L (full-time 4WD models).

Operating tips

The system will operate when the shift lever is in a position other than P, how-
ever to make effective use of the system it is recommended to select a lower
shift range.

■

The system will not operate when

●

Part-time 4WD models: The transfer mode is in H2 or H4.

●

Full-time 4WD models: The transfer mode is in H4L or H4F.

■

If the downhill assist control system indicator flashes

●

In the following situations, the indicator flashes and the system will not oper-
ate:
• The transfer mode is not in L4 (part-time 4WD models) or L4L (full-time

4WD models).

• The shift lever is in P.
• The accelerator or brake pedal is depressed.
• The vehicle speed exceeds approximately 15 mph (25 km/h).
• The brake system overheats.

●

In the following situations, the indicator flashes to alert the driver, but the
system will operate:
• The shift lever is in N.
• The “DAC” switch is turned off while the system is operating.

The system will gradually ceases operation. The indicator will flash during
operation, and then go off when the system is fully off.

■

When the downhill assist control system is operated continuously

This may cause the brake actuator to overheat. In this case, the downhill
assist control system will stop operating, a buzzer will sound and the downhill
assist control system indicator will start flashing, and the “TRAC OFF” indica-
tor light will come on. Refrain from using the system until the downhill assist
control system indicator stays on and “TRAC OFF” indicator light turns off.

vehicle’s performance limitations. Always check the terrain thoroughly and
drive safely.

●

The recommended speed modes for the listed terrains (



P. 313) are only

a reference. The selected mode may not be suitable to actual off-road con-
ditions due to factors such as the type or unevenness of the terrain or the
degree of incline. Check the actual terrain thoroughly and drive safely.

●

After activating Crawl Control, make sure that the Crawl Control indicator
comes on. If the indicator flashes, the vehicle is not under system control.

■

Conditions under which the system may not operate correctly

When driving on the following surfaces, the system may not be able to
maintain a fixed low speed, which may result in an accident:
