ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
The - indicator lamp in the instrument
cluster (
page 28) comes on when you
switch on the ignition (
page 370). It goes
out when the engine is running.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or pre-
vent the natural laws of physics from acting
on the vehicle.
Always adapt your driving style to the pre-
vailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
i
In winter operation, the maximum effective-
ness of the ABS, Adaptive Brake, BAS,
BAS Plus*, EBP, ESP
® and 4MATIC is only
achieved with winter tires (
page 610), or snow
chains as required.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.

74 Safety and SecurityDriving safety systemsSwitching off the ESP
®
(except S 63 AMG)
To improve the vehicle’s traction, turn off
the ESP
® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:


when driving with snow chains


in deep snow


in sand or gravelWhen you switch off the ESP
®


the ESP
® does not stabilize the vehicle


the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for better grip


the electronic traction system will still
apply the brakes to a spinning wheel


the ESP
® continues to operate when
you are braking


you cannot activate the cruise control
or the DISTRONIC Plus* 1ESP
® off/on

Press ESP
® switch1 until the ESP
®
warning lampv in the instrument
cluster comes on.
The ESP
® is switched off.
Warning!
G
The ESP
® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
Warning!
G
Switch on the ESP
® immediately if the afore-
mentioned circumstances do not apply any-
more. Otherwise the ESP
® will not stabilize
the vehicle when it is starting to skid or a
wheel is spinning.
i
When the ESP
® is switched off and one or
more drive wheels are spinning, the ESP
® warn-
ing lampv in the instrument cluster flashes.
However, the ESP
® will then not stabilize the
vehicle.

Driving systems
Vehicle level control with Airmatic
Your vehicle automatically adjusts its ride
height to:

increase vehicle safety


reduce fuel consumption
The vehicle chassis ride height is raised or
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:


Fuel consumption may increase.


Handling may be impaired.1Vehicle level control switch

Start the engine.

Briefly press switch1 to change from
one level setting to the other.
The message:
“Vehicle Rising”
appears in the multifunction display
when changing from normal level to
raised level.
The indicator lamp2 is then lit. The
display switches off when the vehicle is
raised.
Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.
i
These height adjustments are so small that
you may not notice any change.
LevelNormal
For driving on normal roads.
The indicator lamp is off.
Raised
For driving on rough roads or
with snow chains. The indica-
tor lamp is on.

565 Operation
Driving instructions
An electronic speed limiter prevents your
vehicle from exceeding a speed of

All models except S 63 AMG and
S65AMG:
130 mph (210 km/h)


S 63 AMG:
S 65 AMG:
155 mph (250 km/h)


S 63 AMG with Performance Package*:
S 63 AMG with increased top speed*:
S 65 AMG with increased top speed*:
186 mph (300 km/h)
The factory equipped tires on your vehicle
may have a tire speed rating above the
maximum speed permitted by the elec-
tronic speed limiter.
Make sure your tires have the required tire
speed rating as specified for your vehicle in
the “Technical data” section (
page 754),
for example when purchasing new tires.
For information on how to identify the tire
speed rating on a tire’s sidewall, see “Tire
size designation, load and speed rating”
(
page 598).If you are uncertain about the correct read-
ing of the information given on a tire’s side-
wall, any authorized Mercedes-Benz
Center will be glad to assist you.
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
or DISTRONIC Plus* system under such
conditions.
When the vehicle is in danger of skidding,
move gear selector lever to neutral
positionN. Try to keep the vehicle under
control by corrective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed.i
For information on speed ratings for winter
tires, see (
page 601) and (
page 610).
i
For information on driving with snow chains,
see “Snow chains” (
page 611).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.

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.
