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.
