System operation
Press the VSC off switch to turn
on the system.
At this time, the “AUTO LSD”
and VSC off indicators will come
on.
To turn off the system, press the
switch again.
AUTO LSD system (2WD models)
The AUTO LSD system aids traction by using the traction con-
trol system to control engine performance and braking when
one of the rear wheels begins to spin.
The system should be used only when wheel spinning occurs in
a ditch or rough surface.

2424-5. Using the driving support systems
4RUNNER (U)_(OM35B23U)
If the rear wheels spin, the slip
indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.
■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” 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.
When the AUTO LSD system is operating
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.
NOTICE
■Activating while driving
Never activate the AUTO LSD system if the wheel is slipping.
Stop the slipping or spinning before activating.

The slip indicator will flash to indi-
cate that the downhill assist con-
trol system is operating, and the
stop lights and high mounted
stoplight will turn on.
■Operating tips
The system will operate when the shift lever is in any position other than P.
However, to make effective use of the system it is recommended that the shift
lever be shifted to the “2” or “1” range of S.
■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 rear differential is locked.
• The brake system overheats.
The system will cease operation and a buzzer will sound to alert the
driver. At this time, the “TRAC OFF” indicator will come on. Stop the vehi-
cle in a safe place. Refrain from using the system until the indicator stops
flashing and stays on. (There is no problem with continuing normal driv-
ing.)
●In the following situations, the indicator flashes to alert the driver, but the
system will still operate:
• The shift lever is in N. (Engine braking will not occur.)
• 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.

4RUNNER (U)_(OM35B23U)■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 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.

Speed modes
The following table shows
some typical terrains and the
recommended speed modes.
■Crawl Control can be operated when
●The engine is running.
●The shift lever is in any position other than P or N.
●The front-wheel drive control lever or switch is in L4.
●The driver’s door is closed.
■Crawl Control is temporarily canceled when
Vehicle speed exceeds 15 mph (25 km/h). The Crawl Control indicator
flashes until the vehicle speed is reduced.

Driving
4RUNNER (U)_(OM35B23U)■Automatic system cancelation
In the following situations, the system will cease operation and a buzzer will
sound to alert the driver. The Crawl Control indicator will flash until the system
is turned off completely.
●When the shift lever is shifted to P or N
●When the front-wheel drive control lever or switch is shifted to H4
●When the driver’s door is opened
●When the system is malfunctioning
●When the brake system overheats
Stop the vehicle in a safe place. (There is no problem with continuing normal
driving.)
●When the automatic transmission system overheats
Stop the vehicle in a safe place until the automatic transmission fluid tem-
perature warning light goes off.
■Sounds and vibrations caused by the Crawl 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 indicate
that 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 indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
CAUTION
■When using Crawl Control
●Do not overly rely on Crawl Control. This function does not extend the
vehicle’s performance limitations. Always check the terrain thoroughly and
drive safely.
●The recommended speed modes for the listed terrains (P. 250) 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:
●Extremely steep inclines
●Extremely uneven surfaces
●Snow-covered roads, or other slippery surfaces

Multi-terrain Select
: If equipped
The Multi-terrain Select system has 4 terrain modes. When a ter-
rain mode is selected in accordance with terrain conditions,
engine power and active traction control system is controlled to
enhance off-road drivability.
Additionally, guidance messages such as transfer mode selec-
tion advice are displayed on the multi-information display to
assist the driver in operating the vehicle.

◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Multi Terrain ABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface,
or in off-road conditions (such as rough roads, sand and mud)
The Multi Terrain ABS operates in synchronization with the Multi-
terrain Select.
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing engine torque when
trailer sway is detected.
Trailer Sway Control is part of the VSC system and will not operate
if VSC is turned off or experiences a malfunction.
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
Driving assist systems
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.
