Driving safety systems
In this section you will find informations on
the following driving safety systems:

ABS (A
ntilock B

ystem)


BAS (B

ssist S
ystem)


ESP (E
lectronic S
tability P
rogram)
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 with light brake pressure.
The - indicator lamp in the instrument
cluster (
page 22) comes on when you
turn the SmartKey in the starter switch to
position2. It goes out when the engine is
running.Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.

Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and
functions as a reminder to take extra care
while driving.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP is only
achieved with winter 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
The ABS, BAS, ESP 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.

76 Safety and SecurityDriving safety systemsFor more information, see “Practical hints”
(page 261).Switching off the 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


sand or gravelThe switch is located on the center con-
sole.
1ESP off
2ESP on

Press upper half1 of the ESP switch
until the ESP warning lamp v in the
speedometer comes on.
The ESP is deactivated.
!Because of the ESP’s automatic opera-
tion, the engine must be shut off
(SmartKey in starter switch position0
or1) 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.
The ESP will only function properly if
you use wheels of the recommended
tire size.
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.

228 OperationDriving instructionsTire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.C 230 Kompressor (standard in U.S.A.;
optional in Canada), C 320
Your vehicle is factory equipped with
“W”-rated tires, which have a speed rating
of 168 mph (270 km / h).
An electronic speed limiter prevents your
vehicle from exceeding a speed of
130 mph (210 km / h).
C 230 Kompressor (standard in canada;
Canada only)
Your vehicle is factory equipped with
“H”-rated tires, which have a speed rating
of 130 mph (210 km / h).
An electronic speed limiter prevents your
vehicle from exceeding a speed of
130 mph (210 km / h).
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 or,
in case of manual transmission declutch.
Try to keep the vehicle under control by
corrective steering action.
Warning!
G
Even when permitted by law, never operate
a vehicle at greater than the maximum
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.
iFor information on tire speed rating for
winter tires, see “Winter driving”
(page 247).
iFor information on driving with snow
chains, see “Snow chains”
(page 248).
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 loss of control.

248 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
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.


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.
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 75) before setting the vehicle
in motion. This will improve the vehi-
cle‘s traction.
