Driving safety systems
In this section you will find information on
the following driving safety systems:
ABS (A
ntilock B
rake S
ystem)
BAS (B
rake A
ssist S
ystem)
ESP
® (E
lectronic S
tability P
rogram)
Electrohydraulic 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 re-
spond even to light brake pressure.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP
®, and the electrohydraulic brake
system is only achieved with winter
tires (page 287) or snow chains as
required.
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 ABS, BAS, ESP
®, and electrohydraulic
brake system cannot reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
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.
83 Safety and Security
Driving safety systems
Switching off the ESP
®
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 traction control will still brake a
spinning wheel
the ESP
® continues to operate when
you are braking
Turn on the ESP
® immediately if the afore-
mentioned circumstances do not apply
anymore.The switch is located on the lower part of
the center console.
1ESP
® switch (off/on)
Press switch1.
The v ABS/ESP
® warning lamp in
the instrument cluster comes on.
The ESP
® is deactivated.
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.
iWhen the ESP
® is switched off and one
or more drive wheels are spinning, the
v ABS/ESP® warning lamp in the
instrument cluster flashes. However,
the ESP
® will then not stabilize the ve-
hicle.
87 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 ac-
cidents:
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.
iIf the ESP
® is active, the Airbrake is
automatically deactivated.
iIn winter operation, the maximum ef-
fectiveness of the Airbrake is only
achieved with winter tires (M + S tires)
or snow chains as required.
237 Operation
Driving instructions
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
system under such conditions.
When the vehicle is in danger of skidding,
move gear selector lever to positionN.
Try to keep the vehicle under control by
corrective steering action.Road salts and chemicals can adversely
affect 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
efficiency should be tested as soon as
possible after driving is resumed.
For more information, see “Winter driving”
(
page 287).
iFor information on driving with snow
chains, see “Snow chains”
(page 288).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of control loss.
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Warning!
G
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise deadly carbon monoxide
(CO) gases may enter vehicle interior result-
ing in unconsciousness and death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the
vehicle not facing the wind.Warning!
G
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the
road surface is free of ice.
288 OperationWinter drivingSnow chains
Snow 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.
Snow chains should only be used on
the rear wheels. Follow the manufac-
turer’s mounting instructions.
Only use snow chains that are
approved by Mercedes-Benz. Your
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.
iWhen driving with snow chains, you
may wish to deactivate the ESP
®
(
page 83) before setting the vehicle
in motion. This will improve the
vehicle’s traction.

!Only use Michelin tires of the sizes and
types noted above. They are the only
tires approved for use on the SLR. Use
of tires not specially approved for the
SLR could result in unanticipated per-
formance characteristics. For more in-
formation, contact an authorized
Mercedes-Benz Center.
