Ascending and descending Back to "Advice from Bibendum"
Descending

It is essential to change into low ratio 1st gear, before tackling a descent.
Lock the central differential and the rear differential if the vehicle has one.
Go down slowly using engine braking, without touching the pedals.
NEVER USE THE CLUTCH.
If the vehicle starts sliding, accelerate carefully to regain traction.
On very steep hills, brake lightly as well as using engine braking, and progress inch by inch.

Ascending

Lock the differentials.
Approach the climb in low ratio 1st or 2nd gear.
Accelerate steadily and stay in the ratio you selected initially.
Don't accelerate too hard, or the wheels will slide.

If the vehicle fails to climb the slope or the engine is struggling, you will need to:
- Secure the vehicle by pushing firmly on the brakes, without touching the accelerator or the clutch, until the engine stalls.
- While pushing on the brakes, use the clutch pedal to aid selection of reverse gear and gently release all pedals.
- Turn over the starter motor and let the vehicle descend on engine braking.
