Occupant safety
Restraint system introduction
The restraint system can reduce the risk of vehi- cle occupants comingi ntoc ontact with parts of
the vehicle' sinterior in the eventofana ccident.
Furthermore, the restraint system may also
reduce the forces exerted on the vehicle occu-
pant swhen an acciden toccurs.
The restraint system includes:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securings ystem
The components of the restraint system work in
conjunction with each other .They can only offer
the intended level of protection if all vehicle
occupants:
Rare correctly wearing their seat belts.
(Ypage 45)
Radjust their seat and head restraint properly
(Ypage 83).
The driver is also responsible for ensurin gthat
the steering wheel has been correctly posi-
tioned. Observet he information relatin gtothe
correct driver'ss eat position (
Ypage 83).
Always ensure the air bag can inflat eproperly if
deployed (
Ypage 48).
An air bag supplement sacorrectly fastened
seat belt. As an additional safetyd evice, the air
bag increases the level of protection for vehicle
occupants in the eventofana ccident. For exam-
ple, if the protection already provided by acor-
rectly fastened seat belt will suffice, the air bags
are not deployed. Furthermore, only the air bags
that would increase the degree of protection
afforded to the vehicle occupants in the evento fan acciden
tare deployed. Seat belts and air
bags generally do not protect against objects
penetratin gthe vehicle from the outside.
Information on restraint system operatio ncan
be found under "TriggeringofE mergencyTen-
sionin gDevices and air bags" (
Ypage 54).
See “Children in the vehicle” for information on children traveling with you as well as vehicle

If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not performi ts intended protective
function by failing in an acciden tortriggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system .Do
not attempt to modify the wiring as well as
electronic components or their software.

Drive sensibly –save fuel
In order to save fuel, observe the following tips:
XThe tires should alwaysbei nflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenanc ework carried out as
indicated by the servicei ntervals in the Main-
tenance Booklet or by the servicei nterval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in moun-
tainous terrain.
Overrun cutoff
If you are in overrun mode and take your foot off
the accelerator pedal, the fuel supply is cut off
when the engine speed is out of the idle speed
control range.
Drinking and driving
GWARNING
Drinking and driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes ,perceptions and judg-
ment.
The possibility of aserious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engine running in enclosed spaces with-
out sufficien tventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the man-
ufacturer's specifications. An ywork on the
engine should therefore be carried out by quali-
fied and authorized Mercedes-Benz technicians.
The engine settings must not be changed under
any circumstances. In addition, all specific
maintenanc ework must be carried out at regu-
lar intervals and in accordance with the service
requirement softhe dealer listed here on the
inside title page. Details can be found in the
Maintenance Booklet.
Speed limiter
GWARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed could
lead to tire damage or the tire bursting. There is ar isk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load ratin gand speed ratin grequired for
your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the maxi- mum permissible speed based on the tires (tire
and tire pressure). In particular, also observe the tire approval regulations for each country.
You must, under no circumstances, exceed the
speed limit for the tires specified by the speed
index. The speed ratin gisstated in the tire
tables (
Ypage 291).
You can permanently limit the maximum speed
of your vehicle, e.g. for driving on winter tires.
Driving tips135
Driving and parking
Z
Standard:the sensitivity with which the sys-
tem determines the attention level is set to
normal.
Sensitive: the sensitivity is set higher. The
driver is warned earlier.
When ATTENTION ASSIST is switched on and
the vehicle engine is running:
Ron vehicles without steering wheel buttons,
the À indicator lamp in the instrument
cluster lights up
Ron vehicles with steering-wheel buttons, the
display shows the Àsymbol:
-in the status area
-in the Status Overviewof the Assist.menu (Ypage 183)
For vehicles with steering wheel buttons, if you
deactivate ATTENTION ASSIST, the system is
automatically re-activated when you start the
engine. The system sensitivity then corresponds to the last selection activated –standard or sen-
sitive.
If you switch off ATTENTION ASSIST in avehicle
without steering wheel buttons, the system
remains switched off even after you start the
engine. The status of the system after switching
on the engine always corresponds to the status
last selected.
Warning in the display
If the system detectst iredness or increasing
lapses in concentration, the warning Atten‐
tion Assist: TakeaBreak!orAttent.Asst: Take Break!is shown in the display.
An additional warning tone sounds.
XIf necessary, take abreak.
XConfirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest. If you do not take
ab reak and ATTENTION ASSIST continues to
detect increasing lapses in concentration, you
will be warned again after 15 minutes at the
earliest. This will only happen if ATTEN-
TION ASSIST still detectst ypical indicators of
fatigue or increasing lapses in concentration.
PARKTRONIC
General notes
PARKTRONIC is an electronic parking aid. The
system is equipped with ultrasonic sensors in
the front and rear bumpers to monitor the area
around your vehicle. PARKTRONIC indicates vis-
uallya nd audibly the distance between your
vehicle and an object.
Your vehicle features two separate sound emit-
ters with different frequencies for the warning
tones. The warning ranges in front of and behind the vehicle are indicated by different warning
tones.
PARKTRONIC is activated automatically when
you:
Rturn the key to position 2in the ignition lock
Rrelease the parking brake and
Rmove the selector lever to D,Nor R
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). PARKTRONIC is reactivated
at speeds below 10 mph (16 km/h).
Important safety notes
PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate surround-
ings. You are responsible for safe maneuvering,
parking and pulling away.W hen maneuvering,
parking and pulling away,m ake sure that there
are no persons, animals or object sinthe maneu-
vering area.
!Pay particular attention to obstacles above
or below the sensors when parking, such as
flower pots or trailer towbars. PARKTRONIC
does not recognizes uch objectswhen they
are in the immediate vicinity of the vehicle.
You could damage the vehicle or objects.
PARKTRONIC can suffer interference from:
Rultrasonic sources such as atruck's
compressed-air brakes, an automatic car
wash or apneumatic drill
Rattachments to the vehicle, e.g. rear moun-
ted racks
Rnumber plates (vehicle license plates) that
are not affixed flat against the bumper
Rdirty or icy sensors
Remove adetachable trailer coupling if it is no
longer required. PARKTRONIC measures the
minimum detection range to an obstacle from
the bumper, not the ball coupling.

Operation
Information for ajourney
If the vehicle is heavily laden, checkt he tire
pressures,a nd correct them ,ifnecessary
(
Ypage 270).
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicat ethat the
wheels or tires are damaged. If you suspect that
at ire is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
checkt he wheels and tires for damage. Hidden
tire damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tires and wheels checked at a
qualified specialist workshop.
When parkin gyour vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and not at asharp angle. Otherwise, the
tires ,particularly the sidewalls, can get dam-
aged.
