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

BAS (B

ESP (E

SBC (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
ESP warning lamp v in the instrument
cluster 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 and the 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 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. 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 systems
More information can be found in the
"Practical hints" section (
page 288).Switching off the ESP
To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have wheels cut into
surfaces for better grip such as:


s t a r t i n g o u t o n s l i p p e r y s u r f a c e s a n d i n
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
aquaplaning. 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 the ESP’s automatic opera-
tion, the engine must be shut off (key 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.

210 Controls in detailDriving systemsThe following vehicle level settings can be
selected when the vehicle is stationary and
the engine is running:
The switch is located in the lower section
of the center console.

Briefly press switch1 to change from
"Normal" level to "Raised" level. When
vehicle is at "Raised" level, pressing the
switch will return the vehicle to "Nor-
mal" level.

iAt a speed of approx. above 75 mph
(120 km/h) or if the speed amounts to
between 50 mph (80 km/h) and
75 mph (120 km/h) for approx. five
minutes the setting "Raised" is can-
celed. The message

appears in the multifunction
display.
If you do not drive in this speed range,
the "Raised" level remains stored even
if the key is removed from the ignition.

254 OperationDriving instructionsTire speed rating
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 the speed rating.
Regardless of the tire rating, local speed
limits should be obeyed. Use prudent driv-
ing speeds appropriate to prevailing condi-
tions.
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 selector lever to position N or in
case you have a manual transmission, de-
clutch. Try to keep the vehicle under con-
trol by corrective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
We therefore recommend depressing the
brake pedal periodically when traveling at
length on salt-strewn roads.
This can bring road salt impaired braking
efficiency back to normal. A prerequisite
is, however, that this be done without en-
dangering other drivers on the road.
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 while observing the
safety rules in the previous paragraph.
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 re-
sulting in personal injury and possible death.
iFor more information on driving with
snow chains, see "Snow chains"
(page 274).
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.

274 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 the raised level of the level control sys-
tem AIRMATIC DC* (
page 209). Other
settings may result in damage to your vehi-
cle.
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.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 76) before setting the vehicle
in motion. This will improve the vehi-
cle’s traction.
!Use of snow chains is not permissible
with tire size 245 / 45 R17
(page 361).

361 Technical data
Rims and tires
Rims and tires
Use only tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as:

Poor handling characteristics


Increased noise


Increased fuel consumption
Same-sized tires
!Moreover, tires and rims not approved
by Mercedes-Benz may under load ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle can be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A tire inflation
pressure table is located on the fuel fill-
er cap of the vehicle. The tire pressure
should only be adjusted on cold tires.
Follow the tire manufacturer’s mainte-
nance recommendation included with
the vehicle.
