4RUNNER (U)_(OM35B23U)
CAUTION
■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.

Activating the system
The system will activate when
●The vehicle is traveling under 15 mph (25 km/h) with the acceler-
ator and brake pedals released.
●Part-time 4WD models: The front-wheel drive control lever or
switch is in L4.
Full-time 4WD models: The four-wheel drive control switch is in
L4L.
●The rear differential is unlocked (if equipped).
Press the “DAC” switch.
The downhill assist control sys-
tem indicator will come on to
indicate that the downhill assist
control system is activated.
Pressing the switch again turns
the system off.
Downhill assist control system
: If equipped
With the downhill assist control system, the vehicle is able to
descend a steep hill while maintaining a constant low speed of
about 3 mph (5 km/h) without brake pedal operation.

2484-5. Using the driving support systems
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.

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
