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

ABS (A

BAS (B

ESP (E
lectronic S
tability P

4MATIC (Four Wheel Electronic
Traction 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 (
page 24) comes on when you
switch on the ignition. It goes out when the
engine is running.
iIn winter operation, the maximum
effectiveness of the ABS, ESP, and
4MATIC (if so equipped) is only
achieved with winter tires (M + S tires),
or snow chains as required.
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 4MATIC (if so
equipped) cannot reduce this risk.
Always adjust your driving style to the
prevailing 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.

80 Safety and SecurityDriving safety systems
For more information, see “Practical hints”
(page 306) and (
page 312).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:


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
capabilities of an ESP equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the
user’s safety or the safety of others.iThe ESP will only function properly if
you use wheels of the recommended
tire size (
page 380).
!Vehicles without 4MATIC:
Because of the ESP’s automatic
operation, 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
brake system.
For information on vehicles with
4MATIC, see “Four wheel electronic
traction system (4MATIC) with the
ESP” (
page 82).
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.!Turn on the ESP immediately if the
aforementioned circumstances do not
apply anymore.

270 OperationDriving instructionsC 230 Kompressor (Canada only),
C240, C2404MATIC,
C 320 (USA only), C 320 4MATIC
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).
C230KompressorSport, C320Sport
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).C55AMG
Your vehicle is factory equipped with
“Y”-rated tires, which have a speed rating
of 186 mph (300 km/h).
An electronic speed limiter prevents your
vehicle from exceeding a speed of
155 mph (250 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.
iFor information on tire speed rating for
winter tires, see “Winter tires”
(page 290).
iFor information on driving with snow
chains, see “Snow chains”
(page 291).
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.

291 Operation
Winter driving
Block heater (Canada only)
The engine is equipped with a block
heater.
The electrical cable may be installed at an
authorized Mercedes-Benz Center.
Snow 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 79) before setting the vehicle
in motion. This will improve the
vehicle‘s traction.
!Even on vehicles with all-wheel-drive
use snow chains on rear tires only.
Use of snow chains is not permissible
with tire sizes:
