80 Safety and SecurityDriving safety systemsIn this section you will find information on
the following driving safety systems:

ABS (A
ntilock B

ystem)


BAS (B
rake A
ssist S
ystem)


ESP (E
lectronic S
tability P
rogram)


4MATIC (Four Wheel Electronic Trac-
tion 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, ESP, BAS and
4MATIC is only achieved with winter
tires (M + S tires) or snow chains as re-
quired.
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 4MATIC cannot re-
duce 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
For more information, see “Practical hints”
(page 337).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 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.iDistronic* is switched off when ESP is
activated.iThe ESP will only function properly if
you use wheels of the recommended
tire size (
page 422).
!Because of the ESP’s automatic opera-
tion, the engine and ignition must be
shut off (SmartKey in starter switch
position0 or1 or KEYLESS-GO
start/stop button* in position0 or1)
when

the parking brake is being tested on
a brake test dynamometer


the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
may otherwise seriously damage the
brake system.
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.iDistronic* cannot be activated when
the ESP has been deactivated.

230 Controls in detailDriving systemsVehicle level control with Airmatic
Your vehicle automatically adjusts its ride
height to:

reduce fuel consumption


increase vehicle safety
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:


With increasing speed, ride height is re-
duced by up to approximately ¾ in
(20 mm).


With decreasing speed, the ride height
is again raised to the selected vehicle
level.The following vehicle level settings can be
selected when the vehicle is stationary:
Select the “Raised” level setting only when
required by current driving conditions.
Otherwise:


Fuel consumption may increase


Handling may be impairedThe switch with the indicator lamps is lo-
cated on the upper part of the front center
console.

iThese height adjustments are so small
that you may not notice any change.

Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.

279 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 position N. Try
to keep the vehicle under control by cor-
rective steering action.Road salts and chemicals can adversely af-
fect 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 efficien-
cy should be tested as soon as possible af-
ter driving is resumed.
For more information on winter driving, see
“Winter driving” (
page 326).
iFor information on driving with snow
chains, see “Snow chains”
(page 327).
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 control loss.
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.
Warning!
G
If the vehicle becomes stuck in snow, make
sure that 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 in-
terior resulting in unconsciousness and
death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the ve-
hicle not facing the wind.Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose. In-
dicated temperatures just above the freez-
ing point do not guarantee that the road
surface is free of ice.

327 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 83) 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:
