Removing/stowing the reflective
safety jackets
The reflective safety jackets are located in the
safety jacket compartments in the stowage
compartments of the front doors. There are
also safety jacket compartments in the stow-
age compartments of the rear doors, in which
reflective safety jackets can be stowed.
XTo remove: pull out safety jacket bag :
with the reflective safety jacket by loop ;.
XOpen safety jacket bag:and pull out the
reflective safety jacket.
XTo stow: fold the reflective safety jacket,
roll it up and stow it in safety jacket bag :.

edge of the armrest into the safety jacket compartment. Meanwhile, ensure that
loop
;hangs out well within reach.
iRemove a new reflective safety jacket
from its packaging material before sliding it
into the safety jacket compartment. The
packaging material may otherwise cause it
to slip out or make removing it difficult.
Observe the legal requirements in each coun-
try.

RThe reflective safety jackets meet the
requirements defined by the legal standard
only if:
-the correct size is used, and
-the reflective safety jackets are fastened
correctly.
REnsure before use that the reflective safety
jackets are clean and intact. The special
properties may otherwise be compro-
mised.
RThe reflective safety jackets should be
stored in their original packaging in a dry
place away from sources of heat and light.
RThe maximum number of washes specified
is not the only factor influencing the life
span of the reflective safety jackets. Their

life span also depends on use, care, stor-
age, etc.
RThe reflective safety jackets should be dis-posed of and replaced with new ones:
-after 15 washes, and/or
-if the reflective strips have become
scratched, and/or
-if the backing material and/or reflective
strips have become soiled and cannot becleaned off, and/or

Important safety notes
GWARNING
Functions relevant to safety are restricted or
no longer available if:
Rthe engine is not running.
Rthe brake system or the power steering is
malfunctioning.
Rthere is a malfunction in the voltage supply or the vehicle's electrical system.
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely.
GWARNING
You can no longer steer the vehicle if the
steering wheel lock has been engaged. There
is a risk of an accident.
Always switch off the ignition when towing the
vehicle with a tow cable or a tow bar.
GWARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible
gross weight of your vehicle, the:
Rthe towing eye could detach itself
Rthe vehicle/trailer combination could roll-
over.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Details on the permissible gross vehicle
weight of your vehicle can be found on the
vehicle identification plate (
Ypage 408).

This could damage the vehicle.
!The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
It is better to have the vehicle transported
than to have it towed away.
If the vehicle has suffered transmission dam-
age, have it transported on a transporter or
trailer.
The automatic transmission must be in posi-
tion Nwhen the vehicle is being towed. If the
automatic transmission cannot be shifted to
position N, have the vehicle transported on a
transporter or trailer. The battery must be connected and charged.
Otherwise, you:
Rcannot turn the SmartKey to position
2in
the ignition lock
Rcannot release the electric parking brake

formance and increase fuel consumption.
Avoid driving at full throttle and sudden accel-
eration. Never refuel using fuel with a lower
AKI.
Information on refueling (
Ypage 170).
Additives
!Operating the engine with fuel additives
added later can lead to engine failure. Do
not mix fuel additives with fuel. This does
not include additives for the removal and
prevention of residue buildup. gasoline
must only be mixed with additives recom-
mended by Mercedes-Benz. Comply with
the instructions for use on the product
label. More information about recommen-
ded additives can be obtained from any
authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use
branded fuels that have additives.
The quality of the fuel available in some coun-
tries may not be sufficient. Residue could
build up in the injection system as a result. In
such cases, and in consultation with an
authorized Mercedes-Benz Center, the gaso-
line may be mixed with the cleaning additive
recommended by Mercedes-Benz. You must
observe the notes and mixing ratios specified
on the container.
Fuel consumption information
HEnvironmental note
CO
2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO
2emissions are directly related to
fuel consumption and therefore depend on:
Refficient use of the fuel by the engine
Rdriving style
Rother non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO
2emis-
sions by driving carefully and having it serv-
iced regularly.
The vehicle will use more fuel than usual in the
following situations:
Rat very low outside temperatures
Rin city traffic
Ron short journeys
Rin mountainous terrain
Rwhen towing a trailer
Engine oil
General notes
!Never use engine oil or an oil filter of a
specification other than is necessary to ful-
fill the prescribed service intervals. Do not
change the engine oil or oil filter in order to
achieve longer replacement intervals than
those prescribed. You could otherwise
cause engine damage or damage to the
exhaust gas aftertreatment.
Follow the instructions in the service inter-
val display regarding the oil change. Other-
wise, you may damage the engine and the
exhaust gas aftertreatment.
When handling engine oil, observe the impor-
tant safety notes on service products
(
Ypage 409).
The engine oils are matched to the perform-
ance of Mercedes-Benz engines and service
intervals. You should therefore only use
engine oils and oil filters that are approved for
vehicles with maintenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Cen-
