64 Safety and SecurityOccupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are

Seat belts


Emergency tensioning device (ETD)


Air bags


Child seats


Child seat recognition
As independent systems, their protective
effects work in conjunction with each
other.The1indicator lamp in the speedome-
ter dial (
page 24) comes on


for about 4 seconds when you turn the
SmartKey in the starter switch to
position1. It then goes out briefly,
comes on again and remains lit until
you start the engine.


for about 4 seconds when you start the
engine by turning the SmartKey.The1indicator lamp goes out shortly
after you start the engine. This shows that
the restraint systems are operational.
A malfunction in the system has been de-
tected if the1indicator lamp


fails to extinguish after approximately
4 seconds with the SmartKey in the
starter switch position1


does not come on at all


comes on after the engine was started


comes on while driving
For safety reasons, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to
have the system checked.
For more information, see “Practical hints”
(
page 366).

Occupant safety
Head-thorax air bags
1Head-thorax air bag
The head-thorax air bags are deployed

on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front air bags
The passenger-side head-thorax air bag
will only deploy if the system senses that
the passenger seat is occupied.
The head-thorax air bags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
Seat belts
When the engine is started, the seat belt
telltale< illuminates for a maximum of
6 seconds and a warning chime sounds to
remind you and your passenger to fasten
your seat belt.
If after these 6 seconds, the driver’s or the
passenger’s seat belt (with the passenger
seat occupied) are not fastened with all
doors closed,

and the vehicle speed does not exceed
15 mph (25 km/h), the seat belt
telltale< remains illuminated for as
long as either the driver’s or passen-
ger’s seat belt is not fastened.


and the vehicle speed exceeds 15 mph
(25 km/h), the seat belt telltale<
starts flashing and a warning chime
sounds with increasing intensity until
both the driver’s and passenger’s seat
belt are fastened, or for a maximum of
60 seconds from the time the vehicle
speed exceeded 15 mph (25 km/h) if
either the driver’s or passenger’s seat
belt remains unfastened.
If the driver’s or passenger’s seat belt
remains unfastened after 60 seconds,
the seat belt telltale< stops flash-
ing and the warning chime stops
sounding. The seat belt telltale<
then continues to be illuminated for as
long as either the driver’s or passen-
ger’s seat belt are not fastened.
The seat belt telltale< will only go out
if both the driver’s and passenger’s seat
belt (with the passenger seat occupied)
are fastened, or the vehicle is standing still
and a door is opened.

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

ABS (A
ntilock B
rake S
ystem)


BAS (B
rake A
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
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The -indicator lamp in the speedome-
ter dial (
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, the BAS, and
the ESP
® is only achieved with winter
tires (
page 348), 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, and 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.

84 Safety and SecurityDriving safety systems
ESP
®
The Electronic Stability Program (ESP
®) is
operational as soon as the engine is run-
ning and monitors the vehicle’s traction
(force of adhesive friction between the
tires and the road surface) and handling.
The ESP
® recognizes when a wheel is spin-
ning or if the vehicle starts to skid.
By applying brakes to the appropriate
wheel and by limiting engine output, the
ESP
® works to stabilize the vehicle. The
ESP® is especially useful while driving off
and on wet or slippery road surfaces. The
ESP® also stabilizes the vehicle during
braking maneuvers.
The ESP
® warning lampv in the speed-
ometer dial flashes when the ESP
® is en-
gaged.
The ESP
® warning lampv in the speed-
ometer dial comes on when you switch on
the ignition. It goes out when the engine is
running.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The BAS cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of a BAS 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.
Warning!
G
Never switch off the ESP
® when you see the
ESP
®warning lampv flashing in the
speedometer dial. In this case, proceed as
follows:


While driving off, apply as little throttle
as possible.


While driving, ease up on the accelera-
tor.


Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP
® cannot prevent accidents result-
ing from excessive speed.

85 Safety and Security
Driving safety systems
For more information, see “Practical Hints”
(page 365).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:


when driving with snow chains


in deep snow


in sand or gravel
Warning!

er’s safety or the safety of others.
iThe ESP
® will only function properly if
you use wheels of the recommended
tire size (page 439).
!Because of the ESP
®’s automatic oper-
ation, the engine must be turned 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.
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.
Do not switch off the ESP
® when a spare
wheel with collapsible tire is mounted.

86 Safety and SecurityDriving safety systemsWhen you switch off the ESP
®


the ESP
® does not stabilize the vehicle


the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for a better grip


the traction control will still brake a
spinning wheel


the ESP
® continues to operate when
you are brakingThe switch is located on the upper part of
the center console.

The ESP
® warning lampv in the
speedometer dial goes out.
You are now again in normal driving
mode with the ESP
® switched on.
!Turn on the ESP
® immediately if the
aforementioned circumstances do not
apply anymore.
iWhen the ESP
® is switched off and one
or more drive wheels are spinning, the
ESP
® warning lampv in the speed-
ometer dial flashes. However, the ESP
®
will then not stabilize the vehicle.
Warning!
G
When the ESP
® warning lampv is illumi-
nated continuously, the ESP
® is switched
off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!Avoid spinning of a drive wheel for an
extended period with the ESP
®
switched off. This may cause serious
damage to the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
