Emergency spare wheel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type of the spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may
severely impair the driving characteristics.
There is a risk of an accident.
To avoid hazardous situations:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel or
emergency spare wheel that differs in size.
Ronly use a spare wheel or emergency spare
wheel of a different size briefly.
Rdo not switch ESP®off.
Rhave a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
!AMG vehicles with "Minispare" emer-
gency spare wheel: use the "Minispare" emergency spare wheel
only on the rear
axle . If you mount the "Minispare" emer-
gency spare wheel on the front axle, this
could result in damage to the brake system.
If a tire on the front axle is defective, an
intact wheel from the rear axle must first be
replaced with the "Minispare" emergency
spare wheel. The faulty wheel on the front
axle may only then be replaced by the
undamaged wheel from the rear axle.
Make sure to note the placard on the
"Minispare" emergency spare wheel.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 50 mph
(80 km/h).
Snow chains must not be mounted on emer-
gency spare wheels.
General notes
Mounting the emergency spare wheel is
described under "Mounting a wheel"
(
Ypage 428).
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correct the pressure as nec-
3Use of snow chains not permitted. Observe the notes in the "Snow chains" section.

Approved antenna positions
:
Rear roof area
;Rear fender
iOn the rear fenders, it is recommended to
position the antenna on the side of the
vehicle closest to the center of the road.
Use the Technical Specification ISO/TS
21609 when retrofitting RF transmitters
(Road Vehicles - EMC guidelines for installa-
tion of aftermarket radio frequency transmit-
ting equipment). Observe the legal require-
ments for retrofittings.
If your vehicle has installations for two-way
radio equipment, use the power supply or
antenna connections intended for use with
the basic wiring. Be sure to observe the man- ufacturer's additional instructions when
installing.
Deviations with respect to wavebands, maxi-
mum transmission outputs or antenna posi-
tions must be approved by Mercedes-Benz.
The maximum transmission output (PEAK) at
the base of the antenna must not exceed the
following values:
WavebandMaximum
transmission output

The following can be used in the vehicle with-
out restrictions:
RRF transmitters with a maximum transmis-
sion output of up to 100 mW
RRF transmitters with transmitter frequen-
cies in the 380 - 410 MHz waveband and a
maximum transmission output of up to 2 W
(trunked radio/Tetra)
RMobile telephones (2G/3G/4G)
There is no restriction for antenna positions
on the outside of the vehicle for the following

ties
Important safety notes
GWARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels
of the respective original containers. Always
store service products sealed in their original
containers. Always keep service products out
of the reach of children.
HEnvironmental note
Dispose of service products in an environ-
mentally responsible manner.
Service products include the following:
RFuels
RExhaust gas aftertreatment additives, e.g.
DEF
RLubricants (e.g. engine oil, transmission oil)
RCoolant
RBrake fluid
RWindshield washer fluid
RClimate control system refrigerant
Components and service products must be
matched. Only use products recommended
by Mercedes-Benz. Damage which is caused
by the use of products which have not been
recommended is not covered by the
Mercedes-Benz warranty or goodwill ges-
tures. They are listed in this Mercedes-Benz
Operator's Manual in the appropriate section.
Information on tested and approved products
can be obtained at an authorized Mercedes-
Benz Center or on the Internet at
http://bevo.mercedes-benz.com.
You can recognize service products approved
by Mercedes-Benz by the following inscrip-
tion on the containers:
RMB-Freigabe (e.g. MB-Freigabe 229.51)
RMB Approval (e.g. MB Approval 229.51)
Other designations or recommendations indi-
cate a level of quality or a specification in
accordance with an MB Sheet Number (e.g.
MB 229.5). They have not necessarily been
approved by Mercedes-Benz.

Fuel
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refueling.

Low outside temperatures
iDiesel fuel with improved cold flow prop-
erties is available during the winter months.
Further information about fuel properties
can be obtained from oil companies, e.g. at gas stations.
DEF
Important safety notes
Comply with the important safety notes for
service products when handling DEF
(
Ypage 447).
DEF is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
Rnot poisonous
Rcolorless and odorless
Rnot flammable
When you open the DEF container, small
amounts of ammonia vapor may be released.
Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may expe-
rience a burning sensation in your eyes, nose
and throat. Coughing and watering of the
eyes are possible.
Do not inhale ammonia vapors. Fill the DEF
tank only in well-ventilated areas.
Low outside temperatures
DEF freezes at a temperature of approx-
imately 12 ‡(-11 †). The vehicle is delivered
from the factory equipped with a DEF pre-
heating system. Winter operation can thus be guaranteed even at temperatures below 12 ‡
(-11 †).
Additives
!Only use DEF in accordance with ISO
22241. Do not use additives with DEF and
do not dilute DEF with water. This may
destroy the BlueTEC exhaust gas after-
treatment system.
Purity
!Impurities in DEF (e.g. due to other ser-
vice products, cleaning agents or dust) lead
to:
Rincreased emission values
Rdamage to the catalytic converter
Rengine damage
Rmalfunctions in the BlueTEC exhaust gas
aftertreatment system
Assuring the purity of DEF is particularly
important with respect to avoiding malfunc-
tions in the BlueTEC exhaust gas aftertreat-
ment system.
If DEF is pumped out of the DEF tank, e.g.
during repair work, it must not be returned to
the tank. The purity of the fluid can no longer
be guaranteed.

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 447).
