The dimensions of the spare wheel 
(Minispare or collapsible tire) are different 
from those of the road wheels. As a result, 
the vehicle handling characteristics change 
when driving with a spare wheel mounted. 
Adapt your driving style accordingly.
The spare wheel is for temporary use only. 
When driving with spare wheel mounted, 
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center 
as soon as possible to have the spare wheel 
replaced with a regular road wheel.
Never operate the vehicle with more than 
one spare wheel mounted.
Do not switch off the ESP
® when a 
Minispare or collapsible tire is mounted.

Preparing the vehicle
Prepare the vehicle as described 
(page 452).
Vehicles with Minispare wheel 
(except E 63 AMG):
Take the Minispare wheel, wheel 
wrench and the jack out of the trunk 
(page 432).
Vehicles with collapsible tire 
(E 63 AMG only):
Take the collapsible tire, wheel wrench, 
jack and electric air pump out of the 
trunk (
page 432).Lifting the vehicle
Prevent the vehicle from rolling away 
by blocking wheels with wheel chocks 
or other sizeable objects.
One wheel chock is included with the 
vehicle tool kit (
page 434).
When changing wheel on a level surface:
Place the wheel chock in front of and 
another sizeable object behind the 
wheel that is diagonally opposite to the 
wheel being changed.
Always try lifting the vehicle using the jack 
on a level surface. However, should 
circumstances require you to do so on a 
hill, place the wheel chock and the other 
sizeable object as follows:
Place the wheel chock and another 
sizeable object on the downhill side 
blocking both wheels of the axle not 
being worked on.
Warning!
G
The jack is designed exclusively for jacking 
up the vehicle at the jack take-up brackets 
built into either side of the vehicle. To help 
avoid personal injury, use the jack only to lift 
the vehicle during a wheel change. Never 
get beneath the vehicle while it is supported 
by the jack. Keep hands and feet away from 
the area under the lifted vehicle. Always 
firmly set parking brake and block wheels 
before raising vehicle with jack.
Do not disengage parking brake while the 
vehicle is raised. Be certain that the jack is 
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack 
on level surface. Be sure that the jack arm is 
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the 
vehicle.
