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.

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. A lways 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 syst em 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

NOTICE
■To prevent water damage
Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the riverbed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
● Sand and mud that has accumulated in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.
