ECU MERCEDES-BENZ METRIS 2016 MY16 Operator’s Manual

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print.Country-specific variation sare possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to system sand function srelevantt o
safety.

Loading guidelines
Important safetyn otes
GWARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be thrown
about, strikin gvehicle occupants .This also
applies to:
Rluggage or loads
Rseats which have been removed and are
being transported in the vehicle in an
exceptional case.
There is arisk of injury, particularly in the
eventofab rakingmaneuver or abrupt change
in direction.
Always stow objects in such away that they
cannot be tossed about. Beforet raveling,
secure objects, luggage or loads to prevent
them slipping or tippin gover. If you removea
seat, stor eitpreferably outside the vehicle.
GWARNING
As aresult of improperly placed or unevenly
distributed loads, the center of gravityoft he
load being transported may be too high or too
far back. This can significantly impair handling
as well as steering and brakin gcharacteris-
tics. There is arisk of an accident.
Always make sure that the center of gravityo f
the load is:
Rbetween the axles
and
Ras low as possible, near the rear axle.
GWARNING
When the permissible wheel loads, axle loads
and/o rthe maximum permissible gross vehi-
cle weight are exceeded, drivings afetyis
compromised. The handlin gaswell as steer-
ing and brakin gcharacteristic smay be signif-
icantly impaired. Overloaded tires may over-
heat, causing them to burst. There is arisk of
an accident.
When transporting aload, always observet he
permissible wheel loads, axle loads and the
maximum permissible gross vehicle weight
for the vehicle (includin goccupants).
!If you are using aroof carrier,o bservethe
maximum roof load and maximum roof carrier
load.
RDo not stac kluggage or loads higher than the
backrests.
RObjects to be transported should preferably
be stowed in the cargo compartment.
RWhen transporting luggage, always use the
cargo tie-down rings for securingl oads and a
cargo net ,ifinstalled.
RUse cargo tie-down rings and fasteners which
are suitable for the weight and size of the
load.
When using suitable load securin gaids and tie
downs, always follow the manufacturer's oper-
ating instructions, in particular the notes on dis-
card criteria contained therein.
Load securin gaids or tie downs must not be
used if:
Ridentification marksa re missingorillegible
Rthereare yarn breakages ,damage to bearing
seams or other signs of tearing
Rther eare signs of shearing, deformation,
pinching or other damage
Rther eisd amage to clampingorc onnecting
elements
Load securinga ids and tie downs in this condi-
tion are ready for discard and must be replaced.
If you use load securinga ids or tie downs which
are worn out, the load may not be sufficiently
secured and could cause damage to property.
232Loading guidelines
Transporting loads

In the event of an accident, haveadamaged
cargo compartment floor or loading area ,the
cargo tie-down rings and the tie down checked
at as pecialist workshop. Otherwise ,the load
may not be correctly secured the next time any-
thing is stowed.
Even if you follow all loading guidelines, the load
increases the risk of injury in the event of an
accident. Observe the information in the "Secur- ing aload "(
Ypage 234) and "Loa ddistribution"
(Ypage 233) sections.
You wil lfind information abou tthe maximum
roof load and maximum tailgate load in the
"Cargo tie-down points and carrier systems"
section (
Ypage 304). You wil lfind information
abou troof carriers under "Carrier systems"
(
Ypage 238).
Before loading
!
The anti-slip mats cannot be used for secur-
ing goods and must be replaced when they
show signs of:
RPermanent deformatio nand crushing
RCrack formation
RCuts
XTire pressure: check the tire pressure and
correct if necessary (Ypage 270).
XCargo compartment floor: clean the cargo
compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to pre-
vent the load from slipping.
XPlace non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary.
During loading
XObserve the gross axle weight rating and per-
missible gross vehicle weight for you rvehicle.
Take into account that you rvehicle's curb
weight is increased if accessorie soroptional equipment are installed. The maximum pay-
load is thus reduced.
XObserve the notes on load distribution
(Ypage 233).
The overal lcenter of gravity of the load should
always be as low as possible, centered and
betwee nthe axles near the rear axle.
XObserve the legalr equirements of the country
in which you are currently driving.
Checks after loading
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tail-
gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is arisk of poisoning.
Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open.
XSecuring luggage/loads: make sure that
the luggage and/or load is secure before
every journey and at regular intervals during a
long journey, and correct it if necessary.
XDoors/tailgate: close the sliding doors and
tailgate/door.
XTire pressure: adjust the tire pressure
according to the vehicle load (Ypage 270).
XDrivin gstyle: adapt you rdriving style
according to the vehicle load.
Load distribution
General notes
!
Excessive load sonindividual points of the
cargo floor or on the load surface impair vehi-
cle handling characteristics and could cause
damage to the floor covering.
The overal lcenter of gravity of the load should
always be as low as possible, centered and
betwee nthe axles near the rear axle.

GWARNING
The load protectio nnet alone canno trestrain
or secure heavy objects, luggage or heavy
loads. In the event of abrup tchanges in direc-
tion, braking maneuvers or an accident, you
may be struck by unsecured loads. There is a
ris kofi njury, possibly eve nfatal.
Alway sstow objects in such awaythat they
canno tbetossed about. Secure objects, lug-
gage and load stoprevent them slipping or
tipping over, e.g. by lashing them down, even
when using the load protectio nnet.

Carrier systems
GWARNING
When you loa dthe roof, the center of gravity
of the vehicler ises and the driving character-
istics change. If you exceed the maximu mroof
load, the driving characteristics, as wel las
steering and braking, wil lbegreatly impaired.
There is arisk of an accident.
Never exceed the maximu mroof loa dand
adjust you rdriving style.
238Carrier systems
Transporting loads

You will findinformation about the maximum
roof load and maximum tailgat eload under
"Cargo tie-down point sand carrier systems"
(
Ypage 304).
!Make sure that:
Rthe screws of the roof carrier are tightened
to am aximum torque of 7.4l b-ft(10 Nm) in
the threaded hole sprovided and
Rthere is aminimu mboltp enetration of
4t urns.
Only instal lroof carriers and rear racks that
have beena pproved or recommended for
Mercedes-Benz vehicles. This wil lhelpa void
damage to the vehicle.
You can instal laroof carrie ronthe roof and, for
example, arear-mounted cycle rack on the tail-
gate.
Install the protective caps on the securing
thread safter you have removedt he roof carrier.
If you have installed arear rack on the tailgate,
the additiona lweight reduces the assistance
provided by the gas pressure springs whe nthe
tailgate is opened. You wil lthen need more force
to open the tailgate. At low outside tempera-
tures below freezing you wil lneed to provide
extra support for the tailgate to prevent it from
sinking unintentionally.
