The jacking points are located just behind the
front wheel housings and just in front of the rear
wheel housings (arrows). X
Take the ratchet wrench out of the vehicle
tool kit and place it on the hexagon nut of the
jack so that the letters AUF are visible.

Position jack

G WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
! To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
Always pay attention to the instructions and
safety notes in the "Changing a wheel" section
( Y
page 366).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved
for Mercedes-Benz vehicles and the respective
wheel.
! Always use wheel bolts D to mount the
"Minispare" emergency spare wheel. Using
other wheel bolts to mount the "Minispare"
emergency spare wheel could damage the
brake system.

Lowering the vehicle
G WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
! Mercedes-AMG vehicles with a collapsi-
ble spare wheel: before lowering the vehicle,
inflate the collapsible spare wheel with the
tire inflation compressor. The wheel rim could
otherwise be damaged. X
Place the ratchet wrench onto the hexagon
nut of the jack so that the letters AB are visi-
ble. X
Turn the ratchet wrench until the vehicle is
once again standing firmly on the ground. X

Notes on the vehicle equipment – always equip
the vehicle: R
with tires of the same size on a given axle (left
and right) R
with the same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit may be obtained from
a qualified specialist workshop.
Emergency spare wheel
Important safety notes
G WARNING
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: R
adapt your driving style accordingly and
drive carefully. R
never mount more than one spare wheel or
emergency spare wheel that differs in size. R
only use a spare wheel or emergency spare
wheel of a different size briefly. R
do not switch ESP ®
off.R
have 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.
! Mercedes-AMG vehicles with
"Minispare" emergency spare wheel: only
use the "Minispare" emergency spare wheel
on the rear axle . If you mount the
"Minispare" emergency 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 damaged wheel on the front
axle can 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 You can ask for information regarding permitted
emergency spare wheels at an authorized
Mercedes-Benz Center.
Mounting the emergency spare wheel is descri-
bed under "Mounting a wheel" ( Y
page 367).
You should regularly check the pressure of the
emergency spare wheel, particularly prior to
long trips, and correct the pressure as neces-
sary ( Y
page 349). The value on the wheel is
valid.
An emergency spare wheel may also be moun-
ted against the direction of rotation. Observe
the time restriction on use as well as the speed
limitation specified on the emergency spare
wheel.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
When you are driving with the collapsible spare
wheel mounted, the tire pressure loss warning
system or the tire pressure monitor cannot func-
tion reliably. Only restart the tire pressure loss
warning system or tire pressure monitor when
the defective wheel has been replaced with a
new wheel.
Vehicles with tire pressure monitor: after
mounting an emergency spare wheel, the sys-
tem may still display the tire pressure of the
removed wheel for a few minutes. The value dis-
played for the mounted emergency spare wheel
is not the same as the current tire pressure of
the emergency spare wheel.372
