Some vehicles moving up ahead in your lane of travel are difficu lt to
detect, for example two-wheeled vehicles, veh icles with high ground
clearance, loads sticking out the back. Vehicles like this are often
detected late or in some s ituations not at all. •

Adaptive Air Suspension
Air suspension and damping
Applies to veh icles : w ith Adap tive Air Suspens ion
Description
Air suspension and damping can be adjus ted separately.
Adaptive Air Suspens ion is an e lectron ically controlled springing and
damping sys tem. This chass is sys tem makes it eas ie r on the d river by
adapting to the particular si tuation through imperceptible control
processes.
T he
Adaptive Air Su spen sion component regu lates ground clea rance
depending on vehicle speed and driver input . It funct ions indepen
dently from the load cond it io n. Ac ce le rating to a speed above a
predetermined limit will make the vehicle lower itse lf. On the other
hand, dr iv ing more slowly res ults in the vehicle r aising again at
specific speeds.
T he
damping component provides individua l control of the damping
forces . For example , w ith damping characte rist ics set to p rovide
greater comfort, damping is set somewhat harder for a brief period
only as req uir ed, for example, whe n going a ro und a curve or when
brak ing.
Sett ings
Adaptive Air Suspension provides the driver with the opportun ity to
set the chass is characte rist ics also to their individual p refe rence.
With the driving modes
Comfort, Automatic and Dynamic the dr iver
has three chass is sett ings available, ranging from comfort to spo rty.
The
Offroad mode ca n be selected for dr iv ing on poor quality
s tr etc hes of road. In addition,
Li~ provides a fif th mode, w hich can be
selected when exceptiona lly high g round clearance is needed
==> page 179, "C hass is controls ".
T he modes are set in MMI
==> page 180 .
& WARNING
The height of th e parked vehicle can change du e to temperature
fluctuations or changes in load.
0 Note
• Whenever you park yo ur vehicle, always make sure there is
ade qua te clearance above and below t he ve hicle. The height of the
parked vehicle can change as the result of temperature fluctuations,
c hanges in loa d condition and changes in the dr iv ing mode (ground
cleara nce).
• If the veh icle is be ing transported (e .g . by tow truck, tra in , sh ip,
etc.), mount the tie-down cha ins/cables over the running su rface
(circumference) of the tires. Never se cure the vehi cle by the ax le, the
suspension struts or the front or rear tow line eye. For technical
reaso ns, the p ressure in the suspension st ru ts may change dur ing the
t ransport, whic h could result in the vehicle no longer being secured
pro perly.
• If you are goi ng to tow a trailer w ith a tra iler h itch that was
not
ins talled accor ding to f actory s pecifi cations, you mus t activa te t he
t rai ler operation mode manually:::::,
page 182.
[{] Tips
• Before you ca n raise your vehicle using the vehicle jack (for
example, when c hangi ng a flat tire) or a vehicle lift, you must activate
t he jac kin g mode :::::,
page 182.
• On some mode ls, the vehicle can reach its maximum speed on ly in
t he
Automatic and Dynamic modes .•

Chassis controls
Five different driving modes can be set by the driver.
The automatic control processes are speed- and time-dependent. For
example, it is not possible to raise the suspension to a high level
above certain speeds.
When a speed of about 75 mph (120 km/h) is exceeded for more than
30 seconds, the vehicle is automatically lowered to
low level when in
comfort and automatic mode. Ground clearance is about 0.6 inch (15
mm) less, compared to the
normal level.
When a speed of about 100 mph (160 km/h) is exceeded for more
than 20 seconds, the vehicle is automatically lowered to
highway
level
when in automatic and dynamic mode . Ground clearance is
about 1.4 inches (35 mm) less, compared to the
normal level. Road
holding is optimized as a resu lt of the lower center of gravity, and fuel
consumption is reduced as a result of reduced wind resistance .

The segment display @ in the MMI Display =>

Automatic
Select the automatic mode if you prefer a balanced, comfortable
suspension setting. The damp ing characteristics are adjusted accord

Controls and equip
ment Safety first •
Automatic lowering: When a speed of about 75 mph (120 km/h)
is exceeded for more than 30 seconds, the veh icle is automatically
lowered by about 0 .6 inch (15 mm) to the
low level, which is more
suitable for highway speeds. Road holding is optimized as a result of
the lower center of gravity and fuel consumpt ion is reduced as a
result of reduced wind resistance . When a speed of about 100 mph
(160 km/h) is exceeded fo r more than 20 seconds, the vehicle is auto
matically lowered by an additional 0.8 inch (20 mm) to
highway level.
• Automatic raising: When the vehicle is at highway level and the
speed falls below about 80 mph (130 km/h) for more than 20
seconds, the vehicle is automat ically raised to
low level. The vehicle is
automatically raised again to
normal level if the speed falls below
about 44 mph (70 km/h) for a period of 2 minutes. The vehicle is
raised immediately when speed falls below about 22 mph (35 km/h).
Dynamic
Select the dynamic mode if you prefer a sporty suspension setting . In
this mode, the vehi cle is lowe red to
low level wh ile it is still stationary
and sporty damp ing characteristics a re selected . The warning light
c.:> in the instrument cluster wi ll come on for a few seconds just to
remind you of the reduced ground clearance.
If you switch off the engine whi le the vehicle is in the dynamic mode
and then switch on the ignition once again, the
c.:> warning light will
also come on again for a few seconds as a reminder .
• Automatic lowering : When a speed of about 100 mph (160 km/h)
is exceeded fo r more than 20 seconds, the vehicle is automatically
lowered by 0.8 inch (20 mm) to
highway level.
• Automatic raising: The vehicle is automatically raised to low level
again, if the speed falls below about 80 mph (1 30 km/h) for a per iod
of 20 seconds. The vehicle is raised immediately when speed falls
below about 22 mph (35 km/h).
Comfort
Select the comfort mode if you desire a suspension setting with a
special emphasis on comfort. Damping characteristics with a clear
emphasis on comfort are selected in this mode.

Offroad
Select the offroad mode when you have to travel over poor quality
sections of road (e.g. trails) . In this mode, the vehicle is raised to
high

~page 181 .
The offroad mode can only be activated at speeds below 37 mph
(60 km/h). Offroad mode ends automatically and the automatic
mode is activated when a speed of approximately 50 mph (80 km/h)
is exceeded.
Lift
Select the lift mode when exceptionally high ground clearance is
needed at a reduced speed. In this mode, the vehicle is raised to
high

Driving tips
On poor road and off road, there is always only one
motto: Plan ahead and drive slowly!
Please observe the following when driving away from paved
roads:
- Drive only on roads and offroad sections which match the
design of your vehicle and your abilities as a driver. Never
take risks!
- Drive slowly and plan ahead!
- Take into consideration the
ground clearance of your
vehicle .
- Activate the
ESP offroad mode~ page 256 as needed.
