MERCEDES-BENZ E CLASS COUPE 2023 Owners Manual

Removing a wheel
Requirements
= The vehicle is raised (  page 337).
*NOTE Mercedes-AMG vehiclesObserve the notes in the Supplement.
You could otherwise fail to recognize
dangers.
When changing a wheel, avoid applying any force
to the brake disks, as this could impair the level of
comfort when braking.
*NOTE Damage to the wheels\b plastic ele-
ments when changing a wheel
Plastic elements on wheels may be damaged
when removing and repositioning the wheel.
Do not raise the wheels by the plastic
elements when removing and reposition-
ing.*NOTE Damage to threading from dirt on
wheel boltsDo not place wheel bolts in sand or on a
dirty surface.Unscrew the uppermost wheel bolt com-
pletely.Screw alignment bolt 1 into the thread
instead of the wheel bolt.Unscrew the remaining wheel bolts com-
pletely.Remove the wheel.Installing a new wheel
Requirements
= The wheel to be changed is removed and the
alignment bolt is screwed in (  page 339).
*NOTE Mercedes-AMG vehiclesObserve the notes in the Supplement.
You could otherwise fail to recognize
dangers.&WARNING Risk of accident from losing a
wheel
Oiled, greased or damaged wheel bolt/wheel
nut threads or wheel hub/wheel mounting
bolt threads can cause the wheel bolts/wheel nuts to come loose.
Never oil or grease the threads.In the event of damage to the threads,
contact a qualiNed specialist workshop
immediately.Have the damaged wheel bolts or dam-
aged hub threads replaced.Wheels and tires339

Do not continue driving.Observe the information on the choice of tires
(  page 331).
For tires with a speciNed direction of rotation, an
arrow on the side wall of the tire indicates the cor-
rect direction of rotation. Observe the direction of rotation when installing.
*NOTE Damage to the wheels\b plastic ele-
ments when changing a wheel
Plastic elements on wheels may be damaged
when removing and repositioning the wheel.
Do not raise the wheels by the plastic
elements when removing and reposition-
ing.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 331).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 340).
Lowering the vehicle aser a wheel change
Requirements
= The new wheel has been installed
(  page 339).
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.340Wheels and tires

Tighten the wheel bolts evenly in a diagonalpattern in the order indicated 1 to 5 with
an initial maximum force of 59 lb-s (80 Nm).Tighten the wheel bolts evenly in a diagonal
pattern 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 loss warning sys-tem: Restart the tire pressure loss warning
system (  page 319).Vehicles with a tire pressure monitoring sys-
tem: Restart the tire pressure monitoring sys-
tem (  page 318).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-Wheels and tires341

shop. The new wheel must have the cor-
rect dimensions.\bThe emergency spare wheel is secured in the emergency spare wheel bag in the trunk.
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.
= 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.\bVehicles with a tire pressure loss warning sys- tem: if an emergency spare wheel is installed,the tire pressure loss warning system cannot
function reliably. Only restart the system
again when the emergency spare wheel has been replaced with a new wheel.
Vehicles 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:

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.Technical data343

1Front roof area2Rear roof area3Rear fenders4Trunk lid
On vehicles with a panoramic sliding sunroof,installing an antenna in the front or rear roof areais not permitted.
On the rear fenders, it is recommended that you
install the antenna on the side of the vehicle clos- est to the center of the road.
Use Technical SpeciNcation ISO/TS 21609 (Road
Vehicles !

The following can be used in the vehicle without
restrictions:
= two-way radios with a maximum transmission
output of up to 100 mW
= RF transmitters with transmitter frequencies in
the 380 - 410 MHz frequency band and a
maximum transmission output of up to 2 W
(TETRA)
= mobile phones (2G/3G/4G)
There are no restrictions when positioning the
antenna on the outside of the vehicle for the fol-
lowing frequency bands:
= Terrestrial Trunked Radio (TETRA)
= 70 cm frequency band
= 2G/3G/4G
