Vehicle Suspension
This vehicle is fitted with a fully
automatic air suspension system.
It ensures that the vehicle is always at the
correct ride height with varying load
conditions, including luggage
compartment load or when towing.
The system will automatically adjust the
amount of air in the springs to level the
vehicle. Air is supplied either from an air
reservoir or a compressor.
The compressor will run periodically to
refill the reservoir.
Changes in ambient temperature will also
have an effect on vehicle height when the
vehicle is parked.
Caution:
1. Do not overload the vehicle. Vehicle load weights are shown
on page 8 - 4.
2. A slight air loss is expected over time causing the vehicle to lower,
so do not store or place anything
under the vehicle if it is to be left
for an extended period. Speed lowering
When driving at motorway speeds,
the system will lower the vehicle to
improve aerodynamics and vehicle
stability. The suspension will
automatically return the vehicle to the
normal height when the vehicle slows.
Caution: Speed lowering is
undesirable when towing.
Only Jaguar approved towing
equipment will not allow this feature.
Warning messages
If the message ‘VEHICLE TOO LOW’ is
displayed when the ignition is switched
on, start the engine and wait for the
suspension to raise. The vehicle should
not be driven until the message is
cleared.
If the message ‘VEHICLE TOO LOW’ is
displayed when driv
ing, restrict the
vehicle speed and wait for the system to
regain the correct height and the message
will then clear. If the message is displayed
frequently, it is advisable to inform your
Retailer to have the system attended to.
If the message ‘AIR SUSPENSION FAULT’
is displayed at any time, drive with
caution. Have the vehicle checked by a
Retailer at the earliest opportunity.
Note: If your vehicle needs to be
recovered by a roadside emergency
service ensure that the vehicle is securely
lashed by the wheels and NOT the body.
