must be deployed during – and not at the end
of – the collision.
i Airbags are not deployed in all types of
accidents. They are controlled by complex
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbag deployment must take place during
the impact and must be adapted to provide
calculated, additional protection for the
vehicle occupants. Not all airbags are
deployed in an accident.
The different airbag systems work inde-
pendently of each other. However, the
deployment of each individual system will
depend on the type of accident determined
by the control system in the first stages of
the collision (head-on collision, side impact
and overturn) and the extent of the acci-
dent (in particular, the vehicle's rate of
deceleration or acceleration).
The rate of vehicle deceleration or accelera-
tion and the direction of the force are basi-
cally determined by:
R the distribution of forces during the colli-
sion
R the collision angle R
the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided, e.g. the other vehi-
cle
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indication of it.
The vehicle may be deformed significantly,
e. g. on the bonnet or the wing, without an
airbag being deployed. This is the case if only
parts which are relatively easily deformed are
affected and the necessary deceleration does
not occur. Conversely, airbags may be
deployed even though the vehicle suffers only
minor deformations. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are affected and suf-
ficient deceleration occurs as a result.
Belt tensioners, belt force limiters The front seat belts and the outer seat belts
in the rear are equipped with belt tensioners
and belt force limiters.
!
Do not engage the seat belt tongue in the
buckle on the front-passenger seat if the
seat is not occupied. Otherwise the belt tensioner could be activated in an emer-
gency.
If the seat belt is also equipped with a belt
force limiter, the force exerted by the seat
belt on the seat occupant is reduced.
Belt tensioners tighten the seat belts in an
accident, pulling them close against the body.
i Belt tensioners do not correct incorrect
seat positions or incorrectly fastened seat
belts.
Belt tensioners do not pull occupants back
towards the backrest.
The front belt force limiters are synchronised
with the front airbags, which distribute the
forces exerted by the belt force limiters on
the occupant over a greater area.
The seat belts have an automatic comfort-fit
feature. This reduces the retraction force of
the seat belts, which results in increased seat
belt comfort.
When the ignition is switched on, the belt ten-
sioner is triggered:
R only when the restraint systems are opera-
tional (the 1warning lamp lights up

Risk of accident
If the v warning lamp in the speedom-
eter flashes, proceed as follows:
R only depress the accelerator pedal as far
as necessary when pulling away.
R accelerate less when driving.
R adapt your driving style to suit the pre-
vailing road and weather conditions.
Otherwise, the vehicle could go into a skid.
If you drive too fast, 4ETS cannot reduce
the risk of an accident. 4ETS cannot over-
ride the laws of physics.
! If:
R the vehicle is being towed with the front
or rear axle raised,
R the parking brake is being tested using a
dynamometer,
the ignition must be switched off (key in
position 0or 1in the ignition lock). Other-
wise, application of the brakes by 4ETS
could destroy the brake system on the front
or rear axle. Anti-theft systems
Immobiliser
The immobiliser prevents your vehicle from
being started without the correct key.
X To activate: remove the key from the igni-
tion lock.
X To deactivate: turn the key to position 2
in the ignition lock. ATA* (anti-theft alarm system)
A visual and audible alarm is triggered when
the alarm system is primed and you open:
R a door
R a door using the emergency key element
R the rear door or tailgate (convertible)
R the bonnet
The alarm is also triggered if:
R the position of the vehicle is changed.
R a window is smashed.
The alarm is not switched off even if you close
a door again. 1

X To deactivate: unlock the vehicle using the

rear door, the alarm system switches itself
back on again after approximately 40 sec-
onds. Safety

Air conditioning
125Setting the temperature
Different temperatures can be set for the
driver's and front-passenger sides.
X To increase/reduce: turn thumbwheels
2 and 3clockwise or anti-clockwise .
Only change the temperature setting in
small increments. Start at 22 †.
i The temperature of the air from the rear-
compartment air vents and the centre air
vents is the same.
i If you turn the temperature thumbwheel
on one side of the vehicle fully to the right
or left, you will increase or reduce the tem-
perature on the other side of the vehicle at
the same time. Adjusting the air vents
G
Risk of injury
Very hot or very cold air can flow from the
air vents. This could cause burns or frost-
bite to bare skin in the immediate vicinity
of the vents. Keep bare skin away from
these air outlets. If necessary, direct the
airflow away to a different area of the vehi-
cle interior.
Please observe the following notes to ensure
that the air can flow freely through the air
vents:
R keep the air inlet between the windscreen
and the bonnet free of deposits, such as ice
and snow, to guarantee the supply of fresh
air into the vehicle interior.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i Position the sliders for the centre air
vents in the central position to provide vir-
tually draught-free ventilation. Setting the centre air vents Centre air vents

If only summer diesel fuel or less cold-resist-
ant winter diesel fuel (e.g. in Mediterranean
regions) is available, you should add an
amount of flow improver to the fuel corre-
sponding to the outside temperature.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become insufficient. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in a heated
garage. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel engine. Never mix diesel with petrol.
This would damage the fuel system and
engine and could result in a vehicle fire.
Flow improver
The effectiveness of a flow improver is not
guaranteed with every fuel. Observe the infor-
mation provided by the manufacturer when
using a flow improver. Only use flow improv-
ers that have been tested and approved by
Mercedes-Benz. Information about flow
improvers that have been tested and
approved by Mercedes-Benz can be obtained
from any Mercedes-Benz Service Centre. Engine compartment
Bonnet
G
Risk of accident
Do not pull the release lever while the vehi-
cle is in motion. The bonnet may otherwise
open and block your view.
Opening G
Risk of injury
There is a risk of injury if the bonnet is open,
even if the engine is not running.
Some engine components can become
very hot.
To avoid the risk of burns, only touch those
components described in the Owner’s Man-
ual and observe the relevant safety notes. G
Risk of injury
The radiator fan between the radiator and
the engine can start automatically, even if
the key has been removed from the ignition
lock. For this reason you must not reach
into the turning area of the fan. You can
otherwise be injured. Vehicles with a petrol engine:
The electronic ignition system uses high
voltage. For this reason, you must never
touch components of the ignition system
(ignition coil, ignition cable, spark plug con-
nector or test socket) when:
R the engine is running
R the engine is being started
R the ignition is switched on and the engine
is being cranked by hand
Vehicles with a diesel engine:
The electronic injection control uses high
voltage. Therefore, never touch fuel injec-
tion system components when:
R the engine is running
R the engine is being started
R the ignition is switched on
X Make sure that the windscreen wipers are
switched off. G
Risk of injury
The windscreen wipers and wiper linkage
could be set in motion.
When the bonnet is open, you or others
could be injured by the wiper rods. Operation

not properly engaged. Open it again and
close it with a little more force. Operation
