- Always read and heed the information
and WARNINGS
c:;, .&. in Description on
page 113.
A WARNING
- Never rely on the distance control fea
ture of ACC alone to prevent rear-end col
lisions . Always be prepared to brake and
take evasive action to avoid collisions and other acc ident situations.
- Never allow the clos ing speed between
yo u and other vehicles to be so h igh that
the adaptive c ruise control may not be
able to slow your vehi cle safe ly. If clos
ing speed is too high, you m ust app ly the
brakes yourself to reduce the risk of a
rear-end crash.

140 Automatic transmission
Kick-down
The kick-down feature allows the vehicle to
generate maximum acceleration.
When you press the accelerator pedal beyond
the resistance point that is reached at full
throttle, the transmission will select a lower
gear ratio based on vehicle speed and eng ine
RPM. The engine RPM will be controlled to
produce maximum vehicle accelerat ion as
long as you continue to press the accelerator
pedal beyond this resistance point .
& WARNING ,--
Be careful when using the kick-down fea
ture on slippery roads. Rapid acceleration may cause the vehicle to skid.
Dynamic shift program (DSP)
The automatic transmission is electronically
controlled .
The transmission is self adapting and will au
tomatically
select the best shift program suit
ed to the driving conditions and driving style.
The transmission will select one of the
econo
my
programs when you drive at a steady
speed or a gradually changing speed without
heavy acceleration. This achieves optimum
fuel efficiency, with early upshifting and de
layed downshifting.
The transmission will automatically select the
sporty shift programs when you drive at high
er speeds, or with heavy acceleration and fre
quent ly changing speeds. Upshifts are delayed
to make full use of engine power. Oownshift
ing takes place at higher engine speeds than
in the economy programs.
The selection of the most suitable shift pro
gram is a continuous, automatic process. The
driver can also make the transmission switch
to a sporty program by
quickly pressing down
the gas pedal.
This causes the transmission to shift down to
a lower gear to achieve rap id acceleration, e.g .
for quickly passing another veh icle. You do not need to press the gas pedal into the
kick-down
range. After the transmission has upshifted,
the or iginal program is selected according to
your driving style.
An additional shift program allows the automatic transmission to select the proper gear
for uphill and downhill gradients.
This keeps the transmission from shifting up
and down unnecessarily on hills . The trans
mission will shift down to a lower gear when
the driver presses the brake pedal on a down
hill gradient. This makes use of the braking ef
fect of the engine without the need to shift
down manually.
Manual shift program
Using the manual shift program you can
manually select gears.

Rearv iew cam era c overage a rea
The MM I display shows the area covered by
the rearview camera c:>
fig. 166 (!). Objects
that are not in the area covered @are not
shown on the MMI display .
We recommend that yo u practice parking with
the rearview camera in a traffic-free location
or parking lot to become familiar with the sys
tem, the orientation lines, and their function.
When do ing th is, there should be good light
and weather conditions.
I n the MMI disp lay, objects or vehicles appear
closer or further away if:
- you are driving in reverse gear from a level
s u rface onto an incline, or a downward
s lope,
- you are driving in reverse gear toward pro
truding objects,
- the vehicle is carrying too much load in the
rear .
The accuracy of the or ientat ion lines and blue
surfaces dimin ishes if:
- the Adaptive A ir Suspension* is faulty or the
dynamic, offroad or lift mode is on,
- the rearv iew camera does not provide a reli
able image, for example, in poor visibility
cond it ions or if the lens is dirty,
- the image on the screen is not visible due to sun glare and reflection.
Ca ring for the rear view c amer a len s
The rearview camera is located above the rear
license plate bracket . For the parking system
to operate, the lens
c:> fig. 167 must be kept
clean:
- Dampen the lens with a househo ld alcoho l
based glass cleaner, and then wipe the lens
clean with a dry cloth c:>0 .
- Remove snow with a hand brush and ice
preferably with a de-icing spray
c:> ([).
A WARNING
-The parking system cannot rep lace the
dr iver's attention. The driver alone is re-
-
Par king system 145
sponsib le for parking and simi lar d riving
maneuvers.
- Sensors have blind spots in which objects
cannot be detected. Pay spec ia l attention
to small children and an imals because
the sensors cannot always detect them.
-Always keep your eyes on the vehicle's surroundings, us ing the rearview mirror
as well.
- Do not allow yourself to be distracted
from traffic by the rearv iew camera pic
tures .
- If the position and the installation angle
of the camera has changed, for example,
after a rear end collision, do not continue
to use the system for safety reasons.
H ave it checked by a qualified dea le rship.
(D Note
- Low obstacles a lready s ignaled by a
warning can disappear from the system's
detect ion range as they are approached
and w ill not continue to be s ignaled. Ob
jects such as ba rr ie r chains, trai le r d raw
bars, thin painted vert ica l poles or fen
ces may not be detected by the system,
posing r isk of damage .
- Never use warm or hot wate r to remove
snow or ice from the rearview camera
lens -this could cause the lens to crack!
- When cleaning the lens, never use prod
ucts that are ab rasive.

150 Adapti ve Air Susp en sion
Adaptive Air
Suspension
Air suspension and damping
Description
App lies to vehicles: with Adapt ive Air Suspe nsion
Air suspension and damping can be adjusted
separately.
Adaptive Air Suspension is an electronically
controlled springing and damping system .
This chassis system makes it easier on the
driver by adapt ing to the particular situat ion
through imperceptible control processes.
The
Ad apti ve Air Su sp ension component reg
ulates ground clearance depending on vehicle
speed and driver input. It functions independ
ently from the load condition . Accelerating to
a speed above a predetermined limit will make the vehicle lower itself . On the other
hand, driving more slowly results in the vehi
cle raising aga in at specific speeds.
The
d am ping component provides individual
control of the damping forces. For example,
with damping characterist ics set to prov ide
greater comfort, damping is set somewhat
harder for a brief per iod only as required, for
example, when going around a curve or when brak ing .
Set tings
Adapt ive A ir Suspension provides the driver
with the opportun ity to set the chassis charac
teristics also to their individual prefe rence.
W ith the dr iv ing modes
Comfort, Automatic
and Dynamic the driver has three chassis set
tings available, ranging from comfort to spor
ty. The
Offrood mode can be selected for driv
ing on poor quality stretches of road. In addi
tion,
Lift provides a fifth mode, which can be
selected when exceptionally high ground
clearance is needed
c::> page 150, Chassis con
trols.
The modes are set in MMI r:::;, poge 152.
A WARNING
The height of the parked vehicle can
change due to temperature fluctuations or
changes in load.
([) Note
- Whenever you park your vehicle, a lways
make sure there is adequate clearance
above and below the vehicle. The he ight
of the parked vehicle can change as the
result of temperature f luctuations,
changes in load cond ition and changes in
the driving mode (ground clearance).
- If the vehicle is being t ransported (e.g.
by tow truck, train, sh ip, etc.), mount the
tie-down chains/cables over the running
surface (circumference) of the tires. Nev
er secure the vehicle by the axle, the sus
pension struts or the front or rear tow
line eye. For technical reasons, the pres
sure in the suspens ion struts may change
during the transport, which could result
in the vehicle no longer be ing secured
properly .
- If you are going to tow a trailer with a trailer hitch that was
not installed ac
cording to factory specif ications, you
must activate the tra iler operation mode
manually
c;, page 154.
(D Tips
- Before you can raise your vehicle us ing
the vehicle jack (for example, when
changing a f lat t ire) or a veh icle lift, yo u
must activate the jac king mode
c::>poge 154.
-On some mode ls, the vehicle can reach
its maxim um speed only in the
Automat
ic
and Dynamic modes.
Chassis controls
Applies to vehicles: wit h Adaptive A ir Suspensio n
Five different driving modes con be set by the
driver.
The automatic control processes are speed
and t ime -dependent . Fo r example, it is not

possible to raise the suspension to a high leve l
above certain speeds .
When a speed of about 75 mph (120 km/h) is
exceeded for more than 30 seconds, the vehi
cle is automatically lowe red 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 ve
h icle is automat ica lly lowered to
highway lev
el
when in automatic and dynamic mode.
Ground clearance is about 1.4 inches (35 mm)
less, compared to the
normal level. Road
holding is opt imized as a result of the lower
center of gravity, and fuel consumption is re
duced as a result of reduced wind resistance .

0 .8 inch (20 mm) to
highway level.
- Automat ic raising: When the vehicle is at
highway level and the speed falls below
about 80 mph (130 km/h) for more than 20
