2016 TOYOTA 4RUNNER traction control

2404-5. Using the driving support systems
4RUNNER (U)_(OM35B23U)
If all wheels spin, the slip indicator
flashes to indicate that the active
traction control system has been
engaged.
■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 indicate
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 continu-
ing normal driving.)
The system will be automatically restored after a short time.
When the active traction control system is operating
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.

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.

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.

Crawl Control switch
Crawl Control
: If equipped
Allows travel on extremely rough off-road surfaces at a fixed low
speed without pressing the accelerator or brake pedal. Mini-
mizes loss of traction or vehicle slip when driving on slippery
road surfaces, allowing for stable driving.
“ON/OFF” switch
The Crawl Control indicator comes on and the slip indicator flashes when
operating.
Speed selector dial

◆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.

◆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 Differential) (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 control the suspension stabilizer bars in response
to road surface and driving conditions 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
(intermittent) sounds when the hill-
start assist control system is oper-
ating.
