Emergency Tensioning Device (ETD),
seat belt force limiter
The seat belts for the front seats and rear
outer seats are equipped with ETDs and seat
belt force limiters.
The ETDs are designed to activate in the
following cases:
R in frontal or rear-end impacts exceeding
the system’s preset deployment threshold
R if the restraint systems are operational and
functioning correctly, see “SRS indicator
lamp” ( Y page 32)
The ETDs for the front seats will only activate
if the front seat belts are fastened (latch plate
properly inserted into buckle).
The ETDs for the rear outer seats will activate
with or without the respective seat belts
fastened.
In an impact, the ETDs remove slack from the
seat belts in such a way that the seat belts fit
more snugly against the body. Seat belt force
limiters, when activated, are employed to
help reduce the peak force exerted by the
seat belts on occupants during a crash.
i The ETDs do not correct an incorrect seat
position or incorrectly worn seat belts.
The ETDs do not pull occupants back
toward the seat backrest.
GWarning!
Pyrotechnic ETDs that were activated must be
replaced.
For your safety, when disposing of the
pyrotechnic ETDs always follow our safety
instructions. These are available at any
authorized Mercedes-Benz Center.
Correct driver seat adjustmentGWarning!
In order to avoid possible loss of vehicle
control the following must be done before the
vehicle is put into motion:
R seat adjustment
R head restraint adjustment
R steering wheel adjustment
R rear view mirror adjustment
R fastening of seat belts
Steering wheel
GObserve Safety notes, see page 70.XPosition the steering wheel properly
( Y page 71).
Make sure:
R You can reach the steering wheel with your
arms slightly bent at the elbows.
R You can move your legs freely.
R All displays (including malfunction and
indicator lamps) on the instrument cluster
are clearly visible.
Seat belt
GObserve Safety notes, see page 39.XFasten and position your seat belt correctly
( Y page 41).
Make sure:
R The seat belt is always fitted snugly.
R Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder.
R Place the lap portion of the seat belt as low
as possible on your hips.

Driving safety systems
Introduction
This section contains information about the
following driving safety systems:
R ABS (
Antilock Brake System)
R BAS (
Brake Assist System)
R EBB (
Electronic Brake Booster)
R ESP ®
(
Electronic Stability Program)
i In winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
achieved with winter tires, or snow chains
as required.
Safety notes
GWarning!
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.GWarning!
The ABS, the BAS, and the ESP ®
switch off
when the differential locks are switched on.
When the ABS, the BAS, and the ESP ®
are
switched off
R wheels may lock during hard braking
R steering capabilities are reduced
R braking distance is increased
R vehicle stability in standard driving
maneuvers is increased
Make sure the differential locks are switched
on at all times except when driving off-road
for example. Switch on the differential locks
immediately when returning from off-road
driving.
ABS
GObserve Safety notes, see page 52.GWarning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
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) independent
of road surface conditions, provided the
differential locks are not engaged.
