81 Safety and Security
Driving safety systems
Driving safety systems
In this section you will find information on
the following driving safety systems:

ABS (Antilock Brake System)

BAS (Brake Assist System)

ESP® (Electronic Stability Program)

Electro-hydraulic brake system
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
respond even to light brake pressure.
The -indicator lamp in the instrument
cluster comes on (
page 29) when you
switch on the ignition. It goes out when the
engine is running.
Warning!G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns

Wet and slippery road surfaces

Following another vehicle too closely
The ABS, BAS, ESP
®, and the electro-hy-
draulic brake system cannot reduce this
risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
iIn winter operation, the maximum effective-
ness of the ABS, the BAS, the ESP®, and the
electro-hydraulic brake system is only achieved
with winter tires (
page 290) 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.

89 Safety and Security
Performance enhancement system
Performance enhancement system
Airbrake
The Airbrake enhances the vehicle’s driv-
ing stability. It adapts the aerodynamics of
the vehicle to the driving conditions ac-
cording to the speed and the mode set.
This is achieved using a moveable spoiler.
The Airbrake is located at the rear edge of
the trunk lid.
Warning!G
When operating the Airbrake, make sure
there is no danger of anyone being harmed
by the Airbrake operation (i.e. raising and
lowering of flap). Be especially careful when
small children are around.
Warning!G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns

Wet and slippery road surfaces

Following another vehicle too closely
The Airbrake cannot reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
iIn winter operation, the maximum effective-
ness of the Airbrake is only achieved with winter
tires (M + S tires) or snow chains as required.

Hydroplaning
Depending on the depth of the water layer
on the road, hydroplaning may occur, even
at low speeds and with new tires. Reduce
vehicle speed, avoid track grooves in the
road and apply brakes cautiously in the
rain.
Tire traction
The safe speed on a wet, snow covered or
icy road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing
point.Mercedes-Benz recommends winter tires
(
page 290) with a minimum tread depth
of approximately 1/6in (4 mm) on all four
wheels for the winter season to ensure
normal balanced handling characteristics.
On packed snow, they can reduce your
stopping distance compared to summer
tires. Stopping distance, however, is still
considerably greater than when the road is
not covered with snow or ice. Exercise
appropriate caution.
Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use
prudent driving speeds appropriate to
prevailing conditions.Your vehicle is factory equipped with
“(Y)”-rated tires, which have a speed rating
of over 186 mph (300 km/h).
Warning!G
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.
!Avoid spinning of a drive wheel. This may
cause serious damage to the drivetrain which is
not covered by the Mercedes-Benz Limited
Warranty.
Warning!G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire
failure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.
iFor information on tire speed rating for win-
ter tires, see “Winter tires*” (
page 290).
For additional general information on tire speed
markings on tire sidewall, see “Tire speed rating”
(
page 276).

258 Operation
Tires and wheels
For safety reasons, only use tires and rims
which have been tested and approved by
Mercedes-Benz for use on SLR vehicles.
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

For the first 100 miles (160 km) avoid
high-speed cornering. Do not exceed a
speed of 125 mph (200 km/h).
1


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

Tires must be of the correct size for the
rim.

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.
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.
Have worn or damaged tires replaced in
pairs (front pair or rear pair) an make sure
the tires rotate in the direction specified
(
page 261). Otherwise, the driving stabili-
ty of the vehicle will be adversely affected,
especially when driving at high speeds.
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.
!A wheel change should only be carried out
at an authorized Mercedes-Benz Center. Other-
wise there is a danger of damaging the vehicle by
jacking it up incorrectly.
1Please always drive carefully and obey applicable
speed limits.
