Mounting a new wheel
G WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel
bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
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" sec-
tion ( Y
page 427).
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"

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.
! AMG vehicles with "Minispare" emer-
gency spare wheel: use the "Minispare" emergency spare wheel only on the rear
axle . If you mount the "Minispare" emer-
gency 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 faulty wheel on the front
axle may only 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.

An emergency spare wheel may also be
mounted against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
i When you are driving with the collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning sys-
tem 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 system may still display the tire pres-
sure of the removed wheel for a few
minutes. The value displayed for the moun-
ted emergency spare wheel is not the same
as the current tire pressure of the emer-
gency spare wheel.
