(120°C). The coolant temperature may 
rise to 266°F (130°C) at high outside tem-
peratures or when driving in hilly terrain.
The engine should not be operated with 
the coolant temperature above 266°F 
(130°C). Doing so may cause serious en-
gine damage which is not covered by the 
Mercedes-Benz Limited Warranty.

312 Practical hintsFlat tireMounting the spare wheel Preparing the vehicle
Prepare the vehicle as described above 
(
page 302).
Turn spare wheel bracket counter-
clockwise to loosen.
Take the wheel out of the trunk.
Lifting the vehicle
Prevent the vehicle from rolling away 
by blocking wheels with wheel chocks 
(not included) or other sizable objects.
When changing wheel on a level sur-
face:
Place one chock in front of and one 
behind the wheel that is diagonally 
opposite to the wheel being 
changed.
When changing wheel on a hill:
Place chocks on the downhill side 
blocking both wheels of the other 
axle.
Take the vehicle tool kit and the jack 
out of the storage compartment under 
the trunk floor (
page 289).
Warning!
G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a 
result, the vehicle handling characteristics 
change when driving with a mounted spare 
wheel. Adapt your driving style accordingly.
The spare wheel is for temporary use only. 
When driving with spare wheel mounted, en-
sure proper tire pressure and do not exceed 
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.
Warning!
G
The jack is designed exclusively for jacking 
up the vehicle at the jack tubes built into 
both sides of the vehicle. To help avoid per-
sonal injury, use the jack only to lift the ve-
hicle 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 inserted in the jack tube. Always lower 
the vehicle onto sufficient capacity jack-
stands before working under the vehicle.
