446 Controls in detailDriving systemsThe driving systems of your vehicle are de-
scribed on the following pages:

Cruise control (
page 446) and
DISTRONIC Plus*(page 451), with
which the vehicle can maintain a preset
speed.


Airmatic (
page 468) and ABC*
(
page 470) adjust the vehicle sus-
pension characteristics automatically
and control the vehicle level.


Parktronic* (
page 472), Park Assist*
(
page 476) and Advanced Parking
Guidance* (
page 481), which serve
as a parking assistant.


Rear View Camera* (
page 487) is an
electronic and visual parking aid.


Night View Assist* (
page 491) illumi-
nates the road with infrared light in ad-
dition to the normal headlamps.


Blind Spot Assist* (
page 495) de-
tects and warns you about vehicles in
your blind spot.For information on the ABS, Adaptive
Brake, BAS, BAS Plus*, EBP, ESP
® and
PRE-SAFE
® Brake*, see “Driving safety
systems” (page 67).
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.

468 Controls in detailDriving systemsObstacles 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
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.

469 Controls in detail
Driving systems
Vehicle level control with Airmatic

lowered according to the selected level
setting and to the vehicle speed:


W it h inc re a sing s pe ed, ri de hei ght is re -
duced by up to approximately 0.8 in
(20 mm).


With decreasing speed, the ride height
is again raised to the selected vehicle
level.The following vehicle level settings can be
selected when the vehicle is stationary:
Select the “Raised” level setting only when
required by current driving conditions.
Otherwise:

580 OperationEngine compartment
Using a rag, turn cap1 slowly approx-
imately one half turn counterclockwise
to release any excess pressure.

Continue turning the cap counterclock-
wise and remove it.
The coolant level is correct if the level


for cold coolant: reaches the white
marking (plastic bridge) inside the cool-
ant expansion tank


for warm coolant: is approximately
0.6 in (1.5 cm) higher

Add coolant as required.

Replace and tighten cap1.
For more information on coolant, see the
“Technical data” section (
page 771). Windshield washer system and
headlamp cleaning system
The washer fluid reservoir is located on the
left-hand side of the engine compartment
when looking in the direction of travel. It
supplies the windshield washer system
and headlamp cleaning system with wash-
er fluid.Example illustration S 550 with Airmatic1Cap
Vehicles with ABC*1Cap
Fluid for the windshield washer system and
the headlamp cleaning system is supplied
from the windshield washer reservoir. It
has a capacity of approximately 6.87 US qt
(6.5 l).
During all seasons, add MB Windshield
Washer Concentrate “MB SummerFit” to
water. Premix the windshield washer fluid
in a suitable container.

611 Operation
Winter driving
Snow chainsSnow chains should only be driven on
snow-covered roads at speeds not to
exceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.
Please observe the following guidelines
when using snow chains:


Use of snow chains is not permissible
with all wheel/tire combinations
(page 754).


Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.


Only use snow chains that are
approved by Mercedes-Benz. Any
authorized Mercedes-Benz Center will
be glad to advise you on this subject.


Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.


Do not use snow chains on the spare
wheel (
page 754).
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.!
When driving with snow chains, always se-
lect the raised level of the level control system
Airmatic (
page 468) or ABC* (
page 471).
Other settings may result in damage to your
vehicle.
!
Even on vehicles with all-wheel-drive, use
snow chains on rear tires only.
Some tire sizes do not leave adequate clearance
for snow chains. To help avoid serious damage to
your vehicle or tires, make sure that the use of
snow chains is permissible as specified in the
“Technical data” section of this Operator’s
Manual, see “Rims and tires” (
page 754).
!
If snow chains are mounted to the front
wheels, they may scrape against the body or axle
components. The tires or the vehicle could be
damaged as a result.
i
All models except S 63 AMG:
When driving with snow chains, you may wish to
switch off the ESP
® (page 74) before setting
the vehicle in motion. This will improve the
vehicle’s traction.
i
S 63 AMG:
Do not switch off the ESP
® when driving in snow
or with snow chains mounted.
