THE DIFFERENTIAL LOCK*

IMPORTANT INFORMATION

DO NOT engage the diff lock if one or more wheels are slipping - this could damage the transmission. If wheels are slipping, ease off the accelerator before engaging the diff lock.

Discovery is enhanced by the inclusion of an optional lockable differential (diff lock) between the front and rear drive shafts. With the differential locked, the drive shafts to front and rear axles are, in effect, joined together, causing both to rotate at the same speed.

To unlock the differential Move the transfer gear lever to the right - to either ‘H’ (high) or ‘L’ (low) gearbox as required; when the diff lock disengages, the warning light will extinguish.

This feature enhances traction on difficult off-road surfaces. However, with the differential unlocked, the different running requirements of the two axles can be accommodated, thereby enabling Discovery to operate permanently in four-wheel drive for both normal AND off-road use.

When to use the diff lock As a general rule, the differential should be locked only in order to drive on loose or slippery off-road surfaces. ALWAYS unlock the differential for normal road driving or as soon as a surface giving good grip is reached whether high or low gears are selected.

Selecting diff lock The diff lock can be engaged or disengaged either with the vehicle stationary, or when driving at any speed. However, with the vehicle in motion, it is ESSENTIAL to be travelling on firm ground, in a straight line, and without wheel slip.

H4542

Unlike most other four-wheel-drive vehicles, all Land Rover products have permanent four-wheel drive.

To lock the differential Move the transfer gear lever to the left - from either ‘H’ (high) or ‘L’ (low) gearbox (the warning light on the instrument panel will illuminate).
