Emergency wheel
Concept
In the event of a flat tire, the emergency wheel
can be used in place of the wheel with the de‐
fective tire. The emergency wheel is only in‐
tended for temporary use until the defective
tire/wheel has been replaced.
General information
Mount one emergency wheel only.
Also check the tire inflation pressure of the
emergency wheel in the cargo area regularly,
and correct it as needed.
Safety information
WARNING
The emergency wheel has particular di‐
mensions. When driving with an emergency
wheel, changed driving properties may occur,
for instance reduced lane stability when brak‐
ing, longer braking distance, and changed self-
steering properties in the limit area. There is a
risk of an accident. Drive moderately and do
not exceed a speed of 50 mph/80 km/h.◀
Overview
The emergency wheel and the wheel change
tools are located in the cargo area under the
cargo floor panel.

Pull up and remove the cargo floor panel.
