Front Axle Lift System - Porsche 911 Manual

Front axle lift system

The front axle lift system enables the body to be
raised electro-hydraulically at the front by about
40 mm (front edge of front spoiler). This prevents
damage to the body, which can occur when driving
in underground car parks or over speed bumps, for
example.
Operational readiness and
behaviour
– The front axle lift system is operational when the
engine is running and the vehicle is stationary or
up to a maximum speed of approx. 35km/h (
22 mph) or approx. 60 km/h (37 mph) in certain
countries.
– The vehicle is automatically lowered to the basic
level again when a minimum speed of approx.
35 km/h (22 mph) is exceeded (approx.
60 km/h (37 mph) in certain countries).
– When raised, the damping properties of the front
axle change and noise may be heard in the area
of the front axle coil springs during steering
movements.
– At temperatures below approx. - 10 °C, it may
take longer to fully raise the front end of the ve-
hicle. The noise level may increase.
Lift system faults

strument cluster.
