Automatic system cancelation
In the following situations, the system will cease operation and a buzzer will
sound to alert the driver. The Crawl Cont rol 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. 254) 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

■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious problem.
