The driver's front airbag and front-passenger
front airbag are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deployment can offer additional protection
to that provided by the seat belt
R if the seat belt is fastened
R independently of other airbags in the vehi-
cle
R if the vehicle overturns, but only if the sys-
tem detects high vehicle deceleration in a
longitudinal direction 1
Driver's front airbag
2 Front-passenger front airbag Driver's front airbag
1deploys in front of the
steering wheel; front-passenger front airbag
2 deploys in front of and above the glove
compartment.
On vehicles with automatic child seat recog-
nition in the front-passenger seat*, the front-
passenger front airbag 2is only deployed if
the 5 PASSENGER AIRBAG OFF warning
lamp in the centre console is not lit
(Y page 49). This means that there is not a
child restraint system with automatic child
seat recognition* fitted to the front-
passenger seat or that a child restraint sys-
tem with automatic child seat recognition*
has been fitted to the front-passenger seat
incorrectly.
Sidebags G
Risk of injury
If you wish to use seat covers, Mercedes-
Benz recommends that, for safety reasons,
you only use seat covers that have been
approved for Mercedes-Benz vehicles.
The seat covers must be equipped with a
special tear seam for sidebags. Otherwise,
the sidebag cannot deploy correctly and
would therefore fail to provide the intended
protection in the event of an accident. Appropriate seat covers can be obtained
from a Mercedes-Benz Service Centre.
The purpose of sidebag deployment is to
enhance the level of protection for the thorax
(but not the head, neck or arms) of the vehicle
occupants on the side of the vehicle on which
the impact occurs. Saloon shown as an example

Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R Adaptive brake lamps
R ESP ®
( Electronic Stability Program)
R EBV (electronic brake-power distribution)
R ADAPTIVE BRAKE
i In wintry road conditions, always use win-
ter tyres (M+S tyres) and, where necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. G
Risk of accident
The risk of an accident is significantly
increased by driving too fast. This is partic-
ularly the case when cornering as well as
on wet or slippery roads or when driving too
close to the vehicle in front.
The driving safety systems described in this
section cannot reduce this risk nor override
the laws of physics. For this reason, always adapt your driving
style to suit the prevailing road and weather
conditions. Maintain sufficient distance
from other road users and objects on the
road.
ABS (Anti-lock Braking System)
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
Risk of accident
Do not depress the brake pedal several
times in quick succession (pumping).
Depress the brake firmly and evenly. Pump-
ing the brake pedal reduces the braking
effect.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.Safety

Steering wheel
89Steering wheel
Points to remember
Depending on the vehicle equipment, you can
adjust the steering wheel either manually or
electrically*. G
Risk of injury
The electrically adjustable steering
wheel* can be adjusted when the key is
removed from the ignition lock. Therefore,
do not leave children unsupervised in the
vehicle as they could become trapped as
the steering wheel is adjusted. G
Risk of accident
Only adjust the steering wheel when the
vehicle is stationary and do not pull away
until the steering wheel adjustment mech-
anism is locked in position. You might oth-
erwise drive without the steering wheel
adjustment mechanism being locked in
position. As a result you could be distracted
from road and traffic conditions by an unex-
pected movement of the steering wheel
and thereby cause an accident.
The steerability of the vehicle is however
not affected. When you adjust the steering wheel, make
sure that:
R
the steering wheel can be reached with
your arms slightly bent
R you can move your legs freely

ment cluster clearly Adjusting the steering wheel man-

The easy-entry/exit feature makes getting in
and out of your vehicle easier.
The steering wheel swings upwards when
you:
R remove the key from the ignition lock
R open the driver's door when the key is in
the ignition lock or in position 1.
The steering wheel is moved automatically to
the position previously set when the key is
inserted into the ignition lock with the driver's
door closed. G
Risk of injury
Make sure that nobody can become trap-
ped when you activate the easy-entry/exit
feature.
If there is a risk of becoming trapped, stop
the adjustment procedure. To halt the pro-
cedure:
R press the steering-column adjustment
switch
R press one of the memory function posi-
tion buttons
The steering column stops moving immedi-
ately. Never leave children unsupervised in the
vehicle. They could open the driver's door
and thereby unintentionally activate the
easy-entry feature and become trapped.
The most recent position of the steering
wheel is stored when you switch off the igni-
tion or when you store a memory position
(Y page 93).
You can activate and deactivate the easy-
entry/exit feature via the on-board computer
(Y page 138). Controls

10 km/h
R about ten seconds after you have disen-
gaged reverse gear
R if you press button 1for the exterior mir-
ror on the driver's side Memory functions*
Storing settings
You can store up to three different settings
using the memory button.
The following settings are stored as a single
memory preset:
R Position of the seat, backrest and head
restraint
R Dynamic driving seat*: activated/deacti-
vated
R Driver's side: steering-wheel position
R Driver's side: position of the exterior mir-
rors on the driver's and front-passenger
sides G
Risk of injury
The memory function can be used when the
key has been removed. For this reason,
children should never be left unsupervised
in the vehicle. They could otherwise
become trapped when moving the seat or
the steering wheel. G
Risk of accident
Only use the memory function on the
driver’s side when the vehicle is stationary.
You could otherwise be distracted from the traffic conditions by the steering wheel and
seat moving of their own accord, and cause
an accident.
