of fall. The maximum gradient-climbing capability of your vehicle is 100%, which corresponds
to an approach/departure angle of 45°. Note that the vehicle's gradient-climbing capability
depends on the off-road conditions.
R Before tackling steep downhill gradients, select shift range 1.
R
Drive slowly.
R
Avoid high engine speeds – drive at a suitable engine speed (maximum 3000 rpm).

Use the braking power of the engine when driving down a slope. Observe the engine speed,
do not overrev the engine.
