Observe legal requirements. Changing a wheel and fitting the spare
wheel G
Risk of accident
If the spare wheel is more than six years
old, or it does not correspond to the regular
wheel type: have the spare wheel replaced
by a new wheel at the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
Never drive the vehicle with more than one
spare wheel fitted.
Vehicles with different tyre dimensions on
the front and rear axles: wheel and tyre size
of the spare wheel and normal wheel are
different. When using the spare wheel, the
handling characteristics are compromised.
Do not exceed the maximum speed of 80
km/h. G
Risk of accident
Vehicles with AMG equipment: when you fit
the spare wheel, make sure you observe the
following:
R the maximum speed of 80 km/h
R the prescribed tyre pressure
Preparing the vehicle X
Prepare the vehicle as described
(Y page 243).
X If a trailer is coupled, uncouple it.
X Remove the vehicle tool kit and the jack
(Y page 191).
X Remove the spare wheel from the spare
wheel bracket (Y page 192).
X Secure the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
items under the front and rear of the wheel
that is diagonally opposite the wheel you
wish to change.
X On downhill gradients: place chocks or
similar items under both wheels of the
other axle. Raising
the vehicle G
Risk of injury
The jack is designed only to raise the vehi-
cle for a short time while a wheel is being
changed.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar items as jacking supports.
Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted height.
Do not start the engine at any time while
the wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. when starting the engine, opening
or closing a door or the tailgate) and you
could be seriously injured. G
Risk of accident
