■Multi-terrain Select is temporarily canceled when
The front-wheel drive control lever is shifted to H4 when Multi-terrain Select is
in ROCK, MOGUL or LOOSE ROCK mode. The mode indicator will flash until
the lever is shifted back to L4.
■ If the Multi-terrain Select indicator continues to flash
This may indicate a malfunction in the Multi-terrain Select system.
In this case, Multi-terrain Select is automatically canceled. Have your vehicle
inspected by your Toyota dealer.
■ If the Multi-terrain Select indicator goes off while Multi-terrain Select is
operating
● One of the vehicle systems related to Multi-terrain Select may be malfunc-
tioning.
Have your vehicle inspected by your Toyota dealer.
●
The brake actuator may be at risk of overheating.
A buzzer will sound, the “A-TRAC” indicator will go off and the “TRAC OFF”
indicator will come on. Stop the vehicle in a safe place. Refrain from using
Multi-terrain Select until the “A-TRAC” indicator comes back on and the
“TRAC OFF” indicator goes off. (The vehicle can still be driven, even if Multi-
terrain Select is inoperative.)
In the above cases, Multi-terrain Select is automatically canceled.
CAUTION
■ Before driving
To avoid an accident, observe the precautions relating to off-road driving.
(→P. 276)
■ When using Multi-terrain Select
● Do not use the Multi-terrain Select system for normal (on-road) driving.
The Multi-terrain Select system is designed for off-road use only.
● Do not overly rely on Multi-terrain Select. This function does not extend
the vehicle’s performance limitations. Always check the terrain thoroughly
and drive safely.
● The recommended modes for the listed terrains ( →P. 257) are only a refer-
ence. The selected mode may not be suitable to actual off-road conditions
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 selecting a mode, make sure that the Multi-terrain Select indicator
and the selected mode indicator come on. If any related indicator flashes,
the vehicle is not under Multi-terrain Select control.

◆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.

2644-5. Using the driving support systems
4RUNNER (U)_(OM35B46U)
◆Hill-start assist control (if equipped)
Helps to prevent the vehicle from rolling backward when starting on
an incline or slippery slope
◆LSD (Limited Slip Diff erential) (if equipped)
Transfers drive power to the rear tires when front tires spin, and
vice versa, in order to improve traction
◆KDSS (Kinetic Dynamic Suspension System) (if equipped)
Enhances ride comfort and handling response by using a hydraulic
control system to cont rol the suspension stab ilizer bars in response
to road surface and driving condi tions during cornering or off-road
driving
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator flashes to
indicate that the TRAC/VSC/
Trailer Sway Control systems are
operating.
If the vehicle is in danger of slip-
ping or rolling backward when
starting on an incline, or if any of
the drive wheels spins, the slip
indicator flashes to indicate that
the TRAC/VSC/Trailer Sway Con-
trol/hill-start assist control sys-
tems are operating.
The stop lights and high mounted stoplight turn on and a buzzer (intermit-
tent) sounds when the hill-start assist control system is operating.

CAUTION
■ The ABS and Multi Terrain ABS do not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS or Multi Terrain ABS is operating may
exceed that of normal conditions
The ABS and Multi Terrain ABS are not designed to shorten the vehicle’s
stopping distance. Always maintain a safe distance from the vehicle in front
of you, especially in the following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or roads with uneven surfaces
■ TRAC may not operat e effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ Hill-start assist control does not operate effectively when
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.
