Slide the wheel to be mounted onto the align-ment bolt and push it on.&WARNING Risk of injury from tightening
wheel bolts and nuts
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip.
Only tighten wheel bolts or wheel nuts
when the vehicle is on the ground.Be sure to observe the instructions and safety
notes on "Changing a wheel" (  page 420).For safety reasons, only use wheel bolts which
have been approved by Mercedes-Benz and
for the wheel in question.*NOTE Damage to paintwork of the wheel
rim when screwing in the Nrst wheel bolt
If the wheel has too much play when screwing
in the Nrst wheel bolt, the wheel rim paint can
be damaged.
Press the wheel Nrmly against the wheel
hub when screwing in the Nrst wheel
bolt.Tighten the wheel bolts evenly in a diagonal pattern in the order indicated until they are Nnger-tight.Unscrew and remove the alignment bolt.Tighten the last wheel bolt until it is Nnger-
tight.Lower the vehicle (  page 429).

*NOTE Risk of vehicle jack becoming trap-
ped by the AIRMATIC system
If the AIRMATIC system has released air when
raising the vehicle, the jack can become trap-
ped when the vehicle is lowered.
Start the drive system. This adapts the vehicle level.Remove the jack from under the vehicle.To lower the vehicle: place the ratchet onto
the hexagon nut of the jack so that the letters "AB" are visible and turn counter-clockwise.Tighten the wheel bolts evenly in a diagonalpattern in the order indicated 1 to 5 with

the speciNed tightening torque of 111 lb-s
(150 Nm).&WARNING Risk of accident due to incor-
rect tightening torque
The wheels could come loose if the wheel
bolts or wheel nuts are not tightened to the
prescribed torque.
Ensure that the wheel bolts or wheel
nuts are tightened to the prescribed
tightening torque.If you are not sure, do not move the vehi-
cle. Contact a qualiNed specialist work-
shop and have the tightening torque checked immediately.Check the tire pressure of the newly installed
wheel and adjust it if necessary.\bThe following does not apply if the new wheel is an emergency spare wheel.Vehicles with a tire pressure monitoring sys-
tem: restart the tire pressure monitoring sys-
tem (  page 408).Emergency spare wheel
Notes on the emergency spare wheel
&WARNING Risk of accident caused by
incorrect wheel and tire dimensions
The wheel or tire sizes and the tire type of the
emergency spare wheel or spare wheel and
the wheel to be replaced may diMer. The emer-
gency spare wheel or spare wheel can signiN-
cantly impair driving characteristics of the
vehicle.
To prevent hazardous situations:
Drive carefully.Never install more than one emergency
spare wheel or spare wheel that diMers
in size.Only use an emergency spare wheel or spare wheel brieOy.Do not deactivate ESP n
.Have the emergency spare wheel or
spare wheel of a diMerent size replaced
at the nearest qualiNed specialist work-shop. The new wheel must have the cor-
rect dimensions.
Observe the following notes on installing an emer-
gency spare wheel:
= The maximum permissible speed with an
emergency spare wheel installed is 50 mph
(80 km/h).
= Do not install the emergency spare wheel with
snow chains.
= Replace the emergency spare wheel aser six
years at the latest, regardless of wear.
= Use the wheel bolts that are included with the
emergency spare wheel.
= SpeciNed tightening torque: 96 lb-s (130 Nm)
= Check the tire pressure of the emergency
spare wheel installed. Correct the pressure as
necessary.
\bThe speciNed tire pressure is stated on the
label of the emergency spare wheel.430Wheels and tires

\bVehicles with a tire pressure monitoring sys-
tem: if an emergency spare wheel is installed,
the tire pressure monitoring system cannot
function reliably. For a few minutes aser an
emergency spare wheel is installed, the sys- tem may still display the tire pressure of the
removed wheel. Only restart the system again when the emergency spare wheel has been
replaced with a new wheel.

ted subjects:

Notes on technical data*NOTE Mercedes-AMG vehiclesObserve the notes in the Supplement.
You could otherwise fail to recognize
dangers.
The data stated only applies to vehicles with standard equipment. You can obtain further infor-

Vehicle electronics
Two-way radios

q Notes on installing two-way radios
&WARNING Risk of accident due to
improper work on two-way radios
If two-way radios are manipulated or retroNt-
ted incorrectly, the electromagnetic radiation
from the two-way radios can interfere with the vehicle electronics and jeopardize the operat-
ing safety of the vehicle.
You should have all work on electrical
and electronic components carried out
at a qualiNed specialist workshop.&WARNING Risk of accident due to
improper operation of two-way radios
If you use two-way radios in the vehicle
improperly, their electromagnetic radiation
can disrupt the vehicle\bs electronics. This is
the case in the following situations, in particu-
lar:
= The two-way radio is not connected to an
exterior antenna.
= The exterior antenna is installed incor-
rectly or is not a low-reOection antenna.
This could jeopardize the operating safety of
the vehicle.
Have the low-reOection exterior antenna
installed at a qualiNed specialist work-
shop.When operating two-way radios in the
vehicle, always connect them to the low-
reOection exterior antenna.*NOTE Invalidation of the operating permit
due to failure to comply with the instruc-
tions for installation and use
The operating permit may be invalidated if the instructions for installation and use of two-wayradios are not observed.
Only use approved frequency bands.Observe the maximum permissible out-put power in these frequency bands.Only use approved antenna positions.432Technical data

On vehicles with a panorama roof with power tilt/
sliding panel, installing an antenna is not permit-
ted.

Always keep operating Ouids in the
sealed original container.Always keep children away from operat-
ing Ouids.+ENVIRONMENTAL NOTE Pollution of the
environment due to irresponsible disposal
of operating Ouids
Incorrect disposal of operating Ouids can
cause considerable damage to the environ- ment.
Dispose of operating Ouids in an environ-
mentally responsible manner.
Operating Ouids include the following:
= lubricants
= coolant
= brake Ouid
= windshield cleaning agent
= climate control system refrigerant
Only use products approved by Mercedes-Benz.
Damage caused by the use of products that have
not been approved in the vehicle is not covered by the Mercedes-Benz warranty or goodwill gestures.
You can identify operating Ouids approved by
Mercedes-Benz by the following inscriptions on
the container:
= MB-Freigabe (e.g. MB-Freigabe 229.51)
= MB-Approval (e.g. MB-Approval 229.51)
Further information on approved operating Ouids
is available at the following locations:
= in the Mercedes-Benz SpeciNcations for Oper-
ating Fluids by entering the designation
- at https://operatingOuids.mercedes-
benz.com
= at a qualiNed specialist workshop
Notes on brake Ouid
Observe the notes on operating Ouids
(  page 435).
&WARNING Risk of an accident due to
vapor pockets forming in the brake system
The brake Ouid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake Ouid. If the boiling point is too low,
vapor pockets may form in the brake system when the brakes are applied hard.
This causes the braking eMect to be impaired.
Have the brake Ouid renewed at the
speciNed intervals.Have the brake Ouid regularly replaced at a quali-
Ned specialist workshop.
Only use a brake Ouid approved by Mercedes-
Benz according to MB-Freigabe or MB-Approval 331.0.

&WARNING Risk of Nre

&WARNING Risk of Nre and injury from
windshield washer concentrate
Windshield washer concentrate is highly Oam-
mable. If it comes into contact with hot com-
ponents, it may ignite.
Make sure that windshield washer con-
centrate is not spilled near to the Nller
opening.*NOTE Damage to the exterior lighting due
to unsuitable windshield washer Ouid
Unsuitable windshield washer Ouid may dam-
age the plastic surface of the exterior lighting.
Only use windshield washer Ouid which is
also suitable for use on plastic surfaces,
e.g. MB SummerFit or MB WinterFit.*NOTE Blocked spray nozzles caused by
mixing windshield washer OuidsDo not mix MB SummerFit and MB Win-
terFit with other windshield washer Ou-
ids.Do not use distilled or de-ionized water. Other- wise, the Nll level sensor may be triggered errone-
ously.
Recommended windshield washer Ouid:
= above freezing point: e.g. MB SummerFit
= below freezing point: e.g. MB WinterFit
For the correct mixing ratio, refer to the informa-
tion on the antifreeze container.
Mix washer Ouid with windshield washer Ouid all
year round.
Refrigerant

q Notes on refrigerant
Observe the notes on operating Ouids
(  page 435).
*NOTE Damage due to incorrect refrigerant
If a non-approved refrigerant is used, the cli-
mate control system may be damaged.
Use only R!
