Vehicles with an emergency spare wheel:
in the event of a flat tyre, the emergency
spare wheel is fitted according to the descrip-
tion under "Fitting a wheel" (Y page 438).Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at a qualified spe- cialist workshop.
Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Observe the instructions and safety notes in
the "Fitting a wheel" section (Y page 438).
The wear patterns on the front and rear tyres differ depending on the operating conditions.Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss warning system (Y
page 437)or the tyre pres-
sure monitor (Y page 435). Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably
dark place if they are not being used. Protect
the tyres against oil, grease, petrol and diesel. Fitting a wheel
Preparing the vehicle X
Stop the vehicle on solid, non-slippery and
level ground.
X Apply the electric parking brake manually.
X Move the front wheels to the straight-
ahead position.
X Vehicles with manual transmission:
depress the clutch pedal fully and engage
first or reverse gear.
X Vehicles with automatic transmission:
shift the transmission to position P.
X Make sure that in vehicles with AIRMATIC,
the vehicle level is set to "Normal"
(Y page 234).
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the key from the ignition lock.
X Vehicles with KEYLESS-GO start-func-
tion or KEYLESS-GO: open the driver's
door.
The on-board electronics now have status
0. This is the same as the key having been removed. 438

sion surrounding the possible health risk
posed by electromagnetic fields. Approved aerial positions
:
Front roof area
; Rear roof area
= Rear wing
? Boot lid
i On vehicles with panorama sliding sun-
roof, fitting an aerial to the front or rear roof
area is not permitted.
On the rear wing, it is recommended that
you position the aerial on the side of the
vehicle closest to the centre of the road.
Use Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for fitting
aftermarket radio frequency transmitting
equipment") when retrofitting RF (radio fre-
quency) transmitters. Comply with the legal
requirements for add-on parts.
If your vehicle has fittings for two-way radio
equipment, use the power supply or aerial
connections intended for use with the basic
wiring. Be sure to observe the manufacturer's additional instructions when installing.
Deviations with respect to wavebands, maxi-
mum transmission outputs or aerial positions must be approved by Mercedes-Benz. The maximum transmission output (PEAK) at
the base of the aerial must not exceed the
following values: Waveband Maximum
transmission output Short wave
3 - 54 MHz 100 W
4 m waveband
74 - 78 MHz 30 W
2 m waveband
144 - 174 MHz 50 W
Trunked radio/Tetra
380 - 460 MHz 10 W
70 cm waveband
400 - 460 MHz 35 W
GSM/UMTS/LTE 10 W
The following can be used in the vehicle with-
out restrictions:
R RF transmitters with a maximum transmis-
sion output of up to 100 mW
R mobile phones (GSM/DCS/PCS/UMTS/
LTE)
There are no restrictions when positioning the aerial on the outside of the vehicle for the fol-
lowing wavebands:
R trunked radio/Tetra
R 70 cm waveband
R GSM/UMTS/LTE Vehicle electronics

Environmental note
Dispose of service products in an environ-
mentally-responsible manner.
Service products include the following:
R fuels
R exhaust gas aftertreatment additives, e.g.
AdBlue ®
R lubricants (e.g. engine oil, transmission oil)
R coolant

Important safety notes G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. Service products and capacities

Maximum drawbar noseweight
!
Use a drawbar noseweight as close as possible to the maximum permissible noseweight.
Do not use a noseweight of less than 50kg, otherwise the trailer may come loose.
Note that the payload and the rear axle load are reduced by the actual payload.
Towing a trailer is not possible with all models. For further information, see (Y page 284).

However, the actual noseweight must not exceed the value given on the trailer tow hitch
identification plate. In addition, a distinction should be made between towing a trailer and
using a carrier system on the ball coupling of the trailer tow hitch.
Note also that the payload and the rear axle load are reduced by the actual noseweight.
You can attach carrier systems, e.g. bicycle racks or load-bearing implements, on the ball
coupling. The maximum noseweight of 75 kg applies when using carrier systems on the ball
coupling. Permissible rear axle load when towing a trailer
