Driving safety systemsIn this section you will find information on
the following driving safety systems:

ESP (E

SBC brake system (S

ABS
The 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 with light brake pressure.
If the ABS activates during braking, the
ABS/ESP warning lamp
v
in the speed-
ometer dial flashes. Because of the SBC
brake system, you will not feel any pulsa-
tion in the brake pedal.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP, and SBC is only achieved with win-
ter tires (M + S tires), 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
ABS, BAS, ESP and SBC 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, rather use
firm, steady brake pedal pressure. Pumping
the brake pedal defeats the purpose for ABS
and significantly reduces braking effective-
ness.

71 Safety and Security
Driving safety systems
Switching off ESP
To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have drive wheels spin
and thus cut into surfaces for better grip
such as:

starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


in sand or gravel
Warning!
G
The ESP cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.
!Because of ESP’s automatic operation,
the engine must be shut off when

the parking brake is being tested on
a brake test dynamometer.


the vehicle is being towed with the
front axle raised.
Active braking action through the ESP
may otherwise seriously damage the
rear axle brake system.
ESP will only function properly if you
use wheels of the recommended tire
size (page 337).
Warning!
G
ESP should not be switched off during nor-
mal driving other than in the circumstances
described below. Disabling of the system
will reduce vehicle stability in standard driv-
ing maneuvers.iDistronic* cannot be activated when
ESP has been deactivated.

185 Controls in detail
Driving systems
The following vehicle level settings can be
selected when the vehicle is stationary:
The switch and the indicator lamps are lo-
cated in the lower section of the center
console.
Briefly press switch3 to change from
one level setting to the next.
At level 1, indicator lamp2 is illuminat-
ed and at level 2 both indicator lamps
are illuminated. When the vehicle is at
level 2, pressing the switch will return
the vehicle to normal level.

diately raise or lower to the new vehicle
level as selected.
The selected vehicle level setting re-
mains stored in memory even if the en-
gine is turned off and restarted.

220 OperationDriving instructionsTire 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 M+S rated
radial-ply tires for the winter season for all
four wheels to insure normal balanced
handling characteristics. On packed snow,
they can reduce your stopping distance as
compared with summer tires. Stopping
distance, however, is still considerably greater than when the road is not covered
with snow or ice. Exercise appropriate cau-
tion.
Tire speed rating
SL 500
Your vehicle is factory equipped with
“W”-rated tires, which have a speed rating
of 168 mph (270 km / h).
SL 500 with Sport Package* and
SL 55 AMG
Your vehicle is factory equipped with
“W”-rated tires, which have a speed rating
of 168 mph (270 km / h) or “Y”-rated tires,
which have a speed rating of 188 mph
(300 km / h)
An electronic speed limiter prevents your
vehicle from exceeding a speed of
155 mph (250 km / h).Despite the tire rating, local speed limits
should be obeyed. Use prudent driving
speeds appropriate to prevailing condi-
tions.
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.
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 fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or
personal injury and possible death, for you
and for others.iInformation on driving with snow
chains (
page 240).
iInformation on tire speed rating for
winter tires (
page 239).

240 OperationWinter drivingBlock heater (Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at
your authorized Mercedes-Benz Center.
Snow chains
When driving with snow chains, always se-
lect setting 1 of the level control system
(page 184). Other settings may result in
damage to your vehicle.
Snow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 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.


Chains should only be used on the rear
wheels. Follow the manufacturer's
mounting instructions.


Only use snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.
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.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 71) before setting the vehicle
in motion. This will improve the vehi-
cle‘s traction.
!Use of snow chains is not permissible
with tire sizes 285 / 35 R18.
