tem: restart the tire pressure monitoring sys-
tem (  page 450).Emergency spare wheel
Notes on the emergency spare wheel
&WARNING Risk of accident caused by
incorrect wheel and tire dimensions
The wheel or tire sizes and the tire type of the
emergency spare wheel or spare wheel and
the wheel to be replaced may di"Mer. The emer-
gency spare wheel or spare wheel can signi"N-
cantly impair driving characteristics of the
vehicle.
To prevent hazardous situations:
Drive carefully.Never install more than one emergency
spare wheel or spare wheel that di"Mers
in size.Only use an emergency spare wheel or spare wheel brie"Oy.Do not deactivate ESP n
.Have the emergency spare wheel or
spare wheel of a di"Merent size replaced
