If after these 6 seconds the driver’s or the
passenger’s seat belt (with the passenger
seat occupied) is not fastened with both
doors closed,
R
the seat belt telltale 7 remains
illuminated
for as long as either the driver’s
or passenger’s seat belt is not fastened.
R and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt telltale
7 starts flashing and a warning chime
sounds with increasing intensity for a
maximum of 60 seconds or until the
driver’s and passenger’s seat belt are
fastened.
If you and/or your passenger release the
seat belt during driving, the seat belt
telltale 7 starts flashing and the
warning chime sounds as described before.
If the driver’s or the passenger’s seat belt
remains unfastened after 60 seconds, the
warning chime stops sounding, the seat
belt telltale 7 stops flashing but
continues to be illuminated.
After a vehicle standstill, the warning chime
is reactivated and the seat belt telltale
7 is flashing again if the vehicle speed
once exceeds 15 mph (25 km/h).
The seat belt telltale 7 will only go out if
both the driver’s and the passenger’s seat
belt (with the passenger seat occupied) are
fastened, or the vehicle is standing still and a
door is opened.
For more information, see “Practical hints”
(Y page 259).
Emergency Tensioning Device (ETD),
seat belt force limiter The seat belts 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)
R in certain vehicle rollovers if the system
determines an additional degree of
protection
The ETDs will only activate if the seat belts are
fastened (latch plate properly inserted into
buckle).
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. G
Warning!
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 adjustment

seat position and the exterior rear view
mirrors.
Easy-entry/exit feature
This feature allows the driver an easier entry
into and exit from the vehicle. When entering
and exiting the vehicle, the steering wheel is
in its uppermost position.
The easy-entry/exit feature can be activated
or deactivated in the Convenience submenu
of the control system (Y page 108). G
Warning!
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To stop steering wheel movement do one of
the following:
R Move steering wheel adjustment stalk.
R Press one of the memory position buttons.
R Press memory button M.
Do not leave children unattended in the
vehicle, or with access to an unlocked vehicle.
Children could open the driver’s door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
With the easy-entry/exit feature activated,
the steering wheel will return to its last set
position when you close the driver’s door with
the ignition switched on. The steering wheel
will also return to its last set position when
you insert the SmartKey into the starter
switch.
i The last set steering wheel position is
stored when the ignition is switched off or
the position is stored in memory
(Y page 70).
With the easy-entry/exit feature activated,
the steering wheel tilts upwards when you
remove the SmartKey from the starter switch. The steering wheel also tilts upwards when
you open the driver’s door with the SmartKey
in starter switch position
0 or 1.
i When the current position for the steering
wheel is in the uppermost tilt position, the
steering wheel will no longer be able to
move upward when the easy-entry/exit
feature is activated.
The adjustment procedure is briefly
interrupted when the engine is started. G
Warning!
Let the system complete the adjustment
procedure before setting the vehicle in
motion. All steering wheel adjustment must
be completed before setting the vehicle in
motion. Driving off with the steering wheel
still adjusting could cause the driver to lose
control of the vehicle.
Crash-responsive exit aid When you open the driver’s door after an
accident has occurred, the steering column
moves up. The position of the SmartKey in the
starter switch is insignificant. This function
facilitates exiting as well as rescue of vehicle
occupants.
The crash-responsive exit aid can only be
triggered when the easy-entry/exit feature is
activated via the control system.

Vehicles with rain sensor: Do not leave
windshield wipers on an intermittent
setting when the vehicle is taken to an
automatic car wash or during windshield
cleaning. Windshield wipers will operate in
the presence of water sprayed on the
windshield, and windshield wipers may be
damaged as a result.
! Vehicles with rain sensor: If you have set
intermittent wiping, dirt on the surface of
the
rain sensor or optical effects may cause
the windshield wipers to wipe in an
undesired fashion. This could then damage
the windshield wiper blades or scratch the
windshield. You should therefore switch off
the windshield wipers when weather
conditions are dry.
Vehicles with rain sensor: Intermittent wiping
interval is dependent on the wetness of the
windshield. After the initial wipe, pauses
between wipes are controlled by the rain
sensor automatically.
X Turn the combination switch to position I.
Intermittent wiping is interrupted when the
vehicle
is at a standstill and a door is opened.

Warning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result
in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
! Do not run a cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service life of the engine. This is not covered by the
Mercedes-Benz Limited Warranty.
! If an acoustic warning sounds and the
message Release Parking Brake
appears in the multifunction display when
driving off, you have forgotten to release
the parking brake.
Release the parking brake.
! Avoid

spinning of a drive wheel. This may
cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
! Simultaneously depressing the
accelerator pedal and applying the brakes
reduces engine performance and causes
premature brake and drivetrain wear which
is not covered by the Mercedes-Benz

Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury.
G
Warning!
When working on the vehicle, engage the
parking brake and shift the manual
transmission into 1st gear or reverse gear R.
Otherwise the vehicle could roll away which
could result in an accident and/or serious
personal injury.
! Allow the engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature has
been reached.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces.
