Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:

Cruise control (page 419) and
DISTRONIC Plus*(
page 424), with
which the vehicle can maintain a preset
speed.

Airmatic (page 440) (S 550 only) and
ABC* (
page 442) adjust the vehicle
suspension characteristics automati-
cally and control the vehicle level.

Parktronic* (page 444) and Park As-
sist* (
page 448), which serve as a
parking assistant.

Dynamic Rear View Monitor*
(
page 453) is an electronic and visu-
al parking aid.

Night View Assist* (page 461) illumi-
nates the road with infrared light in ad-
dition to the normal headlamps.
For information on the ABS, Adaptive
Brake, BAS, BAS Plus*, EBP, ESP
® and
PRE-SAFE® Brake*, see “Driving safety
systems” (
page 66).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended for driving at a constant speed for
extended periods of time.
You can set or resume the cruise control at
any speed over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
Warning!G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always re-
main responsible for the vehicle’s speed and
for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable to travel at a steady speed.

The use of the cruise control can be dan-
gerous on winding roads or in heavy traf-
fic because conditions do not allow safe
driving at a steady speed.

The use of the cruise control can be dan-
gerous on slippery roads. Rapid changes
in tire traction can result in wheel spin
and loss of control.

Deactivate the cruise control when driv-
ing in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Driving systems
Obstacles and stationary vehicles
DISTRONIC Plus does not brake for obsta-
cles or stationary vehicles. If, for example,
the vehicle detected in front of you chang-
es lanes to bypass an obstacle or station-
ary vehicle in front of it, DISTRONIC Plus
will not brake for the obstacle or stationary
vehicle.Cross-traffic
DISTRONIC Plus may inadvertently detect
crossing vehicles. If you switch on DIS-
TRONIC Plus, for example, at a traffic light
with cross-traffic, the vehicle may sudden-
ly start to drive off.Airmatic (S 550 only)
Airmatic automatically selects the opti-
mum suspension tuning and ride height for
your vehicle.
Airmatic consists of two components:

Level control system

Adaptive Damping System (ADS)
The ADS automatically selects the opti-
mum damping for the respective driv-
ing conditions. At the same time the
suspension is set to either sporty or
comfort.

hicle. The indicator lamp2 is off.Suspension tuning
The Adaptive Damping System (ADS) auto-
matically tunes shock absorbers and
springs.
The suspension tuning is set according to:

your driving style

road surface conditions

the vehicle loading

your choice of suspension style
The program mode selector switch (C/S)
(
page 409) is used to adjust the suspen-
sion tuning:
Start the engine.
Select the desired driving program.
Active Body Control (ABC)*
The ABC system is an active, comput-
er-controlled system that hydraulically ad-
justs the suspension at all four wheels in
response to various driving situations. It
automatically selects the optimum suspen-
sion tuning and ride height for your vehicle.
iThe selected vehicle level setting remains
stored in memory even if the engine is turned off
and restarted except when you

exceed a speed of 75 mph (120 km/h)
or

maintain a speed of between 50 mph
(80 km/h) and 75 mph (120 km/h) for more
than 3 minutes
The vehicle then lowers to regular level.

Warning!G
S63AMG and S65AMG only:
When you switch off the engine, the entire
vehicle is lowered. You should therefore
make sure that no one is near the wheel
housing or under the vehicle when you
switch off the engine. Otherwise, parts of
the individuals body could be trapped.
!S63AMG and S65AMG only:
When you switch off the engine, the entire vehi-
cle is lowered. When parking, position your vehi-
cle in such a way that it will not scrape against a
curb, for example, when it is lowered. Your vehi-
cle could otherwise be damaged.

Warning!G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always remains with the driver.
Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.
!Special attention must be paid to objects
with smooth surfaces or low silhouettes (e.g.
trailer couplings, painted posts, elevated cross-
bars or road curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.

550 Operation
Tires and wheels
Contact an authorized Mercedes-Benz
Center for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and
purchase.Important guidelines

Only use sets of tires and rims of the
same type and make.

Tires must be of the correct size for the
rim.

Break in new tires for approximately
60 miles (100 km) at moderate
speeds.

Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire inflation pressure loss and
damage to the tire beads.

If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.

Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths of less than
1/8in (3 mm).

When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Warning!G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. Contact an authorized
Mercedes-Benz Center for further informa-
tion. If incorrectly sized rims and tires are
mounted:

The wheel brakes or suspension
components can be damaged.

The operating clearance of the wheels
and the tires may no longer be correct.
Warning!G
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on re-
treads. The operating safety of the vehicle
cannot be assured when such tires are used.

700 Practical hints
Towing the vehicle
Mercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.
When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front wheels raised (except
vehicles with 4MATIC) only so far as neces-
sary to have the vehicle moved to a safe
location where the recommended towing
methods can be employed.
!Do not tow-start the vehicle.
!Vehicles with 4MATIC:
Do not tow with one axle raised. Doing so could
damage the transfer case, which is not covered
by the Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground. Observe
instructions for towing the vehicle with all
wheels on the ground.
!Use flatbed or wheel lift/dolly equipment
with SmartKey or SmartKey with KEYLESS-GO*
in starter switch turned to position0.
Do not tow with sling-type equipment. Towing
with sling-type equipment over bumpy roads will
damage radiator and supports.
To prevent damage during transport, do not tie
down vehicle by its chassis or suspension parts.
Switch off the ESP
® (page 73) and the auto-
matic central locking (
page 245).
!Towing of the vehicle should only be done
using the properly installed towing eye bolt.
Never attach tow cable, tow rope or tow rod to
vehicle chassis, frame or suspension parts.
Warning!G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run

there is a malfunction in the brake
system

there is a malfunction in the power
supply or in the vehicle’s electrical
system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey or
SmartKey with KEYLESS-GO* is in starter
switch position2.
