2016 MERCEDES-BENZ METRIS sensor

There is, however, no system availabletoday
that can completely rule out injury or death.
It is also not possible to rule out arisk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the corrects eat position,
the air bag cannot protec tasintended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, alwaysm ake
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sittin gcorrectly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RCorrectly adjust the seats before driving off.
Always make sure the seat backrest sare
positioned as close to the vertical as possible.
The center of the head restraints should sup-
port the back of the head at about eye level.
RMove the driver's and front-passenger seat as
far back as possible. The driver's seat position
must be such that the vehicle can be driven
safely.
RKeep hands on the outside of the steering
wheel rim. This allows the air bag to deploy
fully.
RAlways sit with your back against the seat
backrest when driving. Do not lean forward,
on the door or against the side window. Oth-
erwise, you are in the air bag deployment
area.
RAlways keep your feet in the footwell in front
of the seat. Do not,f or example, place your
feet on the dashboard. Otherwise, your feet
are in the air bag deployment area.
RSuitable restraint systems must alwaysb e
used for persons under 5ft(1.50 m) in height.
The seat belt cannot be worn correctly by
persons who do not reach this height. If children are also traveling in the vehicle,
please take note of the followingp
oints.
RChild restraint systems should preferably be
installed on the rear seats.
ROnly secureachild on the front-passenger
seat in arearward-facing child restraint sys-
tem if the front-passenger front air bag is
deactivated. If the PASSENGER AIR BAG OFF
indicator lamp is permanently lit, the front-
passenger front air bag is deactivated
(
Ypage 44).
RMake sure you observe the instructions and
safety notes on "Occupan t Classification Sys-
tem (OCS)" (Ypage 50) and "Children in the
vehicle" (Ypage 56), as well as the child
restraint system manufacturer's installation
instructions.
Objects in the passenger compartment
could prevent an air bag from functioning
properly. To prevent risks due to the required
air bag speed after deployment, ensure the fol-
lowing before starting the journey:
Rthere are no persons, animals or objects
between the vehicle occupantsa nd an air
bag.
Rthere are no object sbetween the seat, door
and B-pillar.
Rno hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
Rno accessories, such as cup holders, are
attached to the vehicle within the deployment
area of an air bag, e.g. to doors or side win-
dows.
Rthere are no heavy, sharp or fragile object sin
the pocketsofi tems of clothing. Such items
should be suitably stowed elsewhere.
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
Vehicles with window curtain air bags for all

Never modify the doors or parts of the doors. Always have work on the doors or door pan-
eling carrie dout at aqualified specialist work-
shop.
Fron tair bags
Driver's air bag :deploys in front of the steer-
ing wheel. Front-passenger air bag ;deploys in
front of and above the glove box and the center
console.
When deployed, the front air bag soffer addi-
tional heada nd thorax protection on the front
seats.

front air bag (
Ypag e44).
The front-passenger air bag wil lonly deploy if:
Rthe Occupant Classification System (OCS)
has detected that the front-passenger seati s
occupied (
Ypag e50). The PASSENGER AIR
BAG OFF indicator lam pisnot lit
(
Ypag e51)
Rthe restraint system control unit predicts a
high accident severity
Side impact air bags
GWARNING
Unsuitabl eseatc overs coul drestrict or even
prevent the deployment of the air bag sinte-
grated into the seats. Consequently, the air
bag scannot protect vehicl eoccupants as
they are designed to do. In addition, the func- tion of the Occupant Classification System
(OCS) coul dberestricted. This posesa n
increased risk of injury or even fatal injury.
You should only use seatc overs that have
been approved for the respective seatb y
Mercedes-Benz.
Side impact air bags :deploy next to the outer
cushions of the seatb ackrest.
When deployed, the side impact air bag offers
additiona lthorax and pelvis protection. How-
ever, it does not protect the:
Rhead
Rneck
Rarms
In the event of aside impact, the side impact air
bag is deploye donthe side on which the impact
occurs.
The side impact air bag on the front-passenger
side deploys under the following conditions:
Rthe OCS system detects that the front-
passenger seatiso ccupied or
Rthe belttongue has engaged in the beltb uckle
of the front-passenger seat.
If the beltt ongue has engaged in the beltb uckle,
the side impact air bag on the front-passenger
side deploys if the corresponding accident sit-
uation occurs. This is regardless of whethe rthe
front-passenger seatiso ccupied or not.

Trailer stabilization
Observe the important safety guidelines for the
driving safety system (Ypage 62).
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with ahigh center of gravity can
tip over before ESP
®can detect this. There is
ar isk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
ESP
®trailer stabilization counteracts critical
driving situations in good time and thereby pro- vides considerable assistance when driving with
at railer. Trailer stabilization is part of ESP
®. If the sensor system and evaluation logic detect
trailer swinging movements, ESP
®trailer stabi-
lization firstly brakes individual vehicle wheels in
at argeted manner .Itthus counteracts swinging
movements. If the swinging movements do not
stop, the vehicle is braked until the vehicle/
trailer combination is stabilized. If necessary,
the vehicle's engine output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) start stoswerve, you will be able to
stabilize the vehicle/trailer combination only by
braking. ESP
®trailer stabilization helps you to
stabilize the vehicle/trailer combination in this
situation.
ESP
®trailer stabilization is activated above
speeds of about 40 mph (65 km/h).
If ESP
®is switched off or deactivated because of
am alfunction, the trailer stabilization system
will not function.
Crosswind Assist
Observe the important safety guidelines for the
driving safety system (Ypage 62).
Strong crosswind gusts can impair the road-
holding of your vehicle when driving straight
ahead. The Crosswind Assist function integra-
ted in ESP
®reduces these impairments.
Dependin gonthe direction and intensity of the
side wind, Crosswind Assist intervenes auto-
matically. ESP
®intervenes with stabilizing brak-
ing to assist you in keeping the vehicle in the
lane. When Crosswind Assist intervenes, the
display shows the traffic sign for stron gside
winds and the message Crosswind Assist
.
Crosswind Assist is activated automatically
above avehicle speed of approx. 50 mph
(80 km/h) when the vehicle is driving straight
ahead or cornering gently.
Crosswind Assist does not react:
Rin the event of severe jolts and vibrations, e.g.
when driving over uneven surfaces or pot-
holes
Rwhen grip is reduced, e.g. on snow or ice or
when hydroplaning
Crosswind Assist does not work if ESP
®is deac-
tivated or disabled because of amalfunction.

Breaking-in notes
Important safetyn otes
In certain drivingand drivingsafetysystems, the
sensors adjust automatically while acertain dis-
tance is being driven after the vehicle has been
delivered or after repairs. Full system effective- ness is not reached until the end of this teach-in
procedure.
New or replaced brake pads and brake discs
only reach their optimal brakin geffecta fter a
few hundred kilometers of driving. Until then,
compensat efor this by applying greater forcet o
the brake pedal.
The first 1000 miles (1500 km)
For the servicel ife and economy of your vehicle
it is crucial that you break in the engin ewith due
care.
RTherefore, protect the engin efor the first
1000m iles (1500k m) by drivingatv arying
vehicle and engin espeeds.
RAvoid overstraining the vehicle and high
engin espeeds during this period, e.g. driving
at full throttle. Do not exceed Øof the max-
imum speed for each gear.
RDo not change down agear manually in order
to brake.
RTry to avoid depressingt he accelerator pedal
beyond the point of resistance (kickdown).
After 1000m iles (1500km), you can increase
the engin espeed gradually and accelerate the
vehicle to full speed.
iYou should also observet hesenotes on
breaking-in if the engin eorparts of the drive
train on your vehicle have been replaced.
