Important notes on using the jack: = Use only a vehicle-speciNc jack that has been
approved by Mercedes-Benz to raise the vehi-
cle.
= The jack is only designed for raising and hold-
ing the vehicle for a short time while a wheel
is being changed and not for maintenance
work under the vehicle.
= The jack must be placed on a Nrm, Oat and
non-slip surface.
= The foot of the jack must be positioned verti-
cally under the jack support point. Rules of conduct when the vehicle is raised:
= N

ever place your hands and/or feet under the
vehicle.
= Never lie under the vehicle. =
Do no
t start the engine and do not release the
electric parking brake.

WARNING Risk of injur y from incorrect
positioning of the jack
If you do not position the jack correctly at the
appr
opriate jacking point of the vehicle, the
jack could tip with the vehicle raised. 
Only position the jack at the appropriate
jac

king point of the vehicle. The base of
the jack must be positioned vertically
under the jacking point of the vehicle. *
NOTE Damag
e to the vehicle due to the
jack If you do not position the jack at the jack sup-
por
t points provided for this purpose, you
could damage your vehicle. 
Only position the jack at the jack sup-
por

t points provided for this purpose. 
Take the ratchet ring spanner out of the tyre-
c
hange tool kit and place it on the hexagon
nut of the jack so that the letters "AUF" are
visible. 
Position support 2 of jac
k 4 on jack sup-
port point 1. 
Turn ratchet ring spanner 3 cloc
kwise until
jack support 2 sits completely on jack sup-
port point 1 and the base of the jack lies
evenly on the ground. Wheels and tyres

Continue to turn ratchet ring spanner 3 until
t he tyre is raised a maximum of 3 cm oM the
ground. 
Loosen and remove the wheel (  pag
e 480).Removing a wheel
Requirements:
= The v

ehicle is raised.
When changing a wheel, avoid applying any force
to the brake discs, as this could impair the level of
comfort when braking.
* NOTE Damag
e to the wheels' plastic ele-
ments when changing a wheel Plastic elements on wheels may be damaged
when r
emoving and repositioning the wheel. 
Do not raise the wheels by the plastic
elements when r

emoving and reposition-
ing. *
NOTE Damag
e to threading from dirt on
wheel bolts 
Do not place wheel bolts in sand or on a
dir

ty surface. 
Unscrew the uppermost wheel bolt com-
ple

tely. 
Screw centring pin 1 int
o the thread instead
of the wheel bolt. 
Unscrew the remaining wheel bolts com-
ple

tely. 
Remove the wheel. Fitting a new wheel
Requirements:
= The wheel t

o be changed is removed and the
centring pin is screwed in (  page 480). &
WARNING Risk of accident fr
om losing a
wheel
Oiled or greased wheel bolts can cause the
wheel bolts t
o come loose, as too can dam-
aged wheel bolts or wheel hub threads. 
Never oil or grease the threads. 
In the event of damage to the threads,
cont

act a qualiNed specialist workshop
immediately. 
Have the damaged wheel bolts or dam-
ag

ed hub threads replaced. 
Do not continue driving. 
Observe the information on the choice of tyres
( pag

e 472).
For tyres with a speciNed dir
ection of rotation, an
arrow on the side wall of the tyre indicates the 480
Wheels and tyres

correct direction of rotation. Observe the direc-
tion of r
otation when Ntting.
* NOTE Damag
e to the wheels' plastic ele-
ments when changing a wheel Plastic elements on wheels may be damaged
when r
emoving and repositioning the wheel. 
Do not raise the wheels by the plastic
elements when r

emoving and reposition-
ing. 
Slide the wheel to be mounted onto the cen-
tr
ing pin and push it on. &
WARNING Risk of injur
y from tightening
wheel bolts and nuts
If you tighten the wheel bolts or wheel nuts
when t
he vehicle is raised, the jack could tip. 
Only tighten wheel bolts or wheel nuts
when t

he vehicle is on the ground. 
Be sure to observe the instructions and safety
no

tes on "Changing a wheel" (  page 472). 
For safety reasons, only use wheel bolts which
ha

ve been approved by Mercedes-Benz and
for the wheel in question. 
Tighten the wheel bolts evenly in a diagonal
patt
ern in the order indicated until they are
Nnger-tight. 
Unscrew and remove the centring pin. 
Tighten the last wheel bolt until it is Nng
er-
tight. 
Lower the vehicle ( pag
e 481). Lowering the vehicle
aser a wheel c
hange Requirements:
= The ne

w wheel has been Ntted ( page 480).
* NOTE Risk of v
ehicle jack becoming trap-
ped by the AIRMATIC system If the AIRMATIC system has released air when
r

aising the vehicle, the jack can become trap-
ped when the vehicle is lowered. 
Start the engine. This adapts the vehicle
le

vel. 
Remove the jack from under the vehicle. 
To lower the vehicle: place t
he ratchet onto
the hexagon nut of the jack so that the letters
"AB" are visible and turn anti-clockwise. 
Tighten the wheel bolts evenly in a diagonal
patt
ern in the order indicated 1 to 5 with
an initial maximum force of 80 Nm. 
Tighten the wheel bolts evenly in a diagonal
patt
ern in the order indicated 1 to 5 with
the speciNed tightening torque of 150 Nm. Wheels and tyres

&
WARNING Risk of accident due t o incor-
rect tightening torque
The wheels could come loose if the wheel
bolts or wheel nuts ar
e not tightened to the
prescribed torque. 
Ensure that the wheel bolts or wheel
nuts ar
e tightened to the prescribed
tightening torque. 
If you are not sure, do not move the vehi-
cle. Cont

act a qualiNed specialist work-
shop and have the tightening torque
checked immediately. 
Check the tyre pressure of the newly Ntt
ed
wheel and adjust it if necessary.
% The following does not apply if the new wheel
is an emer
gency spare wheel. 
Vehicles with a tyre pressure monitoring sys-
t
em: restart the tyre pressure monitoring sys-
tem ( page 472). Emergency spare wheel

incorrect wheel and tyre dimensions
The wheel or tyre size and the tyre type of the
emer
gency 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 Nt mor
e than one emergency
spare wheel or spare wheel that diMers
in size. 
Only use an emergency spare wheel or
spar
e wheel brieOy. 
Do not deactivate ESP n
. 
Have the emergency spare wheel or
spar

e wheel of a diMerent size replaced
at the nearest qualiNed specialist work- shop. The new wheel must have the cor-
r

ect dimensions. %
The emergency spare wheel is secured in the
emer
gency spare wheel bag in the boot.
Observe the following notes on Ntting an emer
-
gency spare wheel:
= The maximum permissible speed with an
emergency spare wheel Ntted is 80 km/h.
= Do not Nt 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: 130 Nm
= Check the tyre pressure of the emergency
spare wheel Ntted. Correct the pressure as
necessary.
% The speciNed tyr
e pressure is stated on the
label of the emergency spare wheel. 482

%
Vehicles with a tyre pressure monitoring sys-
t em: if an emergency spare wheel is Ntted, the
tyre pressure monitoring system cannot func-
tion reliably. For a few minutes aser an emer-
gency spare wheel is Ntted, the system may
still display the tyre pressure of the removed
wheel. Only restart the system again when the
emergency spare wheel has been replaced
with a new wheel.

NOTE Pr
emature wear through improper
maintenance Improper maintenance may cause vehicle
com

ponents to wear more quickly and the
vehicle's operating permit may be invalidated. 
Always have work on the engine elec-
tr

onics and related components carried
out at a qualiNed specialist workshop. *

Notes on Ntting
tw
o-way radios &
WARNING Risk of accident due t
o
improper work on two-way radios
If two-way radios are manipulated or r
etroNt-
ted incorrectly, the electromagnetic radiation
from the two-way radios can interfere with the
vehicle electronics and jeopardise the operat-
ing safety of the vehicle. 
You should have all work on electrical
and electr

onic components carried out
at a qualiNed specialist workshop. &
WARNING Risk of accident due t
o
improper operation of two-way radios
If you use two-way radios in the vehicle
im
properly, their electromagnetic radiation
can disrupt the vehicle's electronics. This is
the case in the following situations, in particu-
lar:
= The two-way radio is not connected to an
exterior aerial.
= The exterior aerial is Ntted incorrectly or is
not a low-reOection aerial.
This could jeopardise the operating safety of
the vehicle. 
Have the lo
w-reOection exterior aerial Nt-
ted at a qualiNed specialist workshop. 
When operating two-way radios in the
v

ehicle, always connect them to the low-
reOection exterior aerial. 484
