WARNING
■
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. 311) 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.
■

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
