Porsche Active Suspension Management (PASM) with Air Suspension and Level Control
PASM with air suspension and level control is an active shock absorber adjustment and ride height balancing system. The variable shock absorber system individually selects the relevant shock absorber stiffness for each wheel depending on the driving situation and driving conditions. The level control system automatically balances load changes and maintains a constant ride height. Driving safety, agility, and comfort are optimized.
Three different chassis setups can be selected at the push of a button:
Comfort mode ensures comfortable chassis tuning.
The SPORT chassis setup offers very sporty shock absorber tuning.
SPORT PLUS mode offers particularly sporty shock absorber tuning (e.g. for race circuit driving). The vehicle is also lowered by approx. 0.4 in. (10 mm) compared to the normal level, thereby switching to low level.
Apart from the manual mode selection, the PASM also adjusts the shock absorber setting toward more sporty or more comfortable depending on the driving situation.
If vehicles with air suspension are left stationary for several weeks, the ride height can be reduced. The vehicle automatically re-adjusts to the correct ride height when you start the engine. This can take several minutes, depending on the operating state. Ground clearance is reduced during this time.
Switching PASM mode on
The mode cannot be changed if a door or the tailgate is opened or when the engine is switched off.
When the vehicle is stopped, the ride height may be adjusted automatically in order to balance the vehicle load.
Using normal level
The ground clearance at normal level is approx. 7.5 in. (190 mm).
Using terrain level
The terrain level in off-road mode is intended for off-road driving, field tracks, forest paths, etc. The vehicle is raised by around 1.6 in. (40 mm) compared to normal level.
Switching terrain level on and off
Terrain level can only be selected manually and at speeds of below approx. 55 mph (90 km/h).
The vehicle is automatically raised to terrain level when off-road mode is switched on.
Using low level
Low level can be selected manually and remains activated in all speed ranges.
