rized Mercedes-Benz Center.
Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.

Flat tire
Flat tire
In the case of a flat tire, you may tempo-
rarily use the spare wheel when observing
the following restrictions:
Do not exceed a vehicle speed of
50 mph (80 km / h).
Drive to the nearest tire repair facility
to have the flat tire repaired or re-
placed as appropriate.
Do not operate vehicle with more than
one spare wheel mounted.
Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.
Turn on the hazard warning flashers.
Engage the steering wheel lock in the
straight-ahead position and set the
parking brake.
Move the selector lever toP.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described under
“Preparing the vehicle” on this page.
Take the spare wheel out of the trunk
(page 407).
Take the wheel wrench and the jack
out of the trunk (
page 407).
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 surface:
Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
Warning!
G
The dimensions of the Minispare wheel and
the collapsible tire are different from those
of the road wheels. As a result, the vehicle
handling characteristics change when driv-
ing with a spare wheel mounted.
The spare wheel should only be used tempo-
rarily, and replaced with a regular road
wheel as quickly as possible.

426 Practical hintsFlat tireWhen changing wheel on a hill:
Place chocks on the downhill side
blocking both wheels of the other axle.
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench). The jack take-up brackets are located di-
rectly behind the front wheel housing and
in front of the rear wheel housing.
1Jack take-up bracket
2Jack
3Crank
Position jack2 on firm ground under
the respective jack take-up bracket1.
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.
