FRONT SUSPENSION

NEW RANGE ROVER

DESCRIPTION AND OPERATION

High ride height

This position is used to improve approach and
departure angles and when wading. When at standard
ride height, pressing the up switch will select high ride
height provided the road speed is below 56 km/h (35
mph). The high ride height indicator will flash during
the height change. When the change is complete the
indicator will remain constantly illuminated, and
standard ride height indicator will be extinguished.
The indicator in the instrument pack will also be
illuminated. If speed exceeds 56 km/h (35 mph), the
vehicle will return to standard profile.

Extended ride height

This position is achieved if chassis is grounded
leaving wheel or wheels unsupported. Initial ECU
reaction is to lower (deflate) affected springs. After a
timed period the ECU detects no height change, it
therefore reinflates springs to extended profile in an
attempt to regain traction. The position will be held for
10 minutes, after which time the vehicle will
automatically return to standard ride height.

Pressing the down switch will lower vehicle 20 mm to
high profile.

If vehicle speed exceeds 56 km/h (35 mph) the
vehicle will immediately lower to standard ride height.
This speed could be achieved, for example, by
wheelspin.

VEHICLE TRANSPORTATION

New vehicles are transported from the factory with the
EAS system electronically ’frozen’ in access mode.
When road speed exceeds 40 km/h (25 mph), the
vehicle will rise to low ride height. It will return to
access mode if speed falls below 38.4 km/h (24 mph).
This condition is cancelled at pre-delivery inspection,
by entering the appropriate command via TestBook.

Vehicle transportation/recovery

CAUTION: When an air suspension vehicle
is secured to a transporter using the
chassis lashing eyes, there is a possibility

due to air leakage, self levelling or operation of
ride height controls that the tension of the
securing straps will be lost. To prevent this the
ride height should be set to access mode before
securing to transporter.

If the engine cannot be run and the vehicle is not in
access mode, the vehicle can be transported, but it
must be secured to the transporter by the roadwheels,
not the chassis.
