Changing a wheel
Introduction to the topic
You should carry out a wheel change yourself
only when the v
ehicle is parked safely, you
are familiar with the safety procedures and
have access to the correct equipment. Some
models are delivered from the factory with-
out a jack or box spanner. If this is the case,
wheels should be changed by a qualified
workshop.
The jack supplied with the vehicle is only de-
signed for changing a wheel when one vehi-
cle tyre is damaged and has to be replaced. If
both tyres on one side of the vehicle, both
tyres on one axle, or all tyres are damaged,
seek expert assistance. WARNING
Changing a wheel can be dangerous, espe-
cially when carried out at the side of a road.
Please note the f
ollowing steps in order to
reduce the risk of serious injuries:
x Stop the vehicle as soon as possible and
when safe to do so. Park the vehicle at
a safe distance from moving traffic in
order to carry out the wheel change.
x All passengers and children in particular
must be at a safe distance and away
from the area of work during the wheel
change.
x Switch on the hazard warning lights to
warn other road users.
x Check that the surface the vehicle is
parked on is level and firm. If necessary,
use a large, strong board or similar sup-
port for the jack.
x Only change the wheel yourself when
you feel confident with carrying out the
procedure. If not, seek expert assistance.
x Always use suitable and undamaged
tools to change the wheel.
x Always switch off the electric drive via
the ignition and move the selector lever to the P position to reduce the risk of
unintended v
ehicle movement.
x Switch on the electronic parking brake.
x The wheel bolt tightening torque should
be checked with a correctly functioning
torque wrench immediately after chang-
ing a wheel.
x In the case of vehicles with a Tyre Pres-
sure Loss Indicator, the system must be
re-synchronised immediately after
a wheel change
