Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.
Lowering the vehicle

Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.

Pull the jack out of the jack support
tube.

Install jack tube cover.1 - 5Wheel bolts

Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1to5), until all bolts are tight.
Observe a tightening torque of 80 lb-ft
(110 Nm).
Warning!
G
Always replace wheel bolts that are dam-
aged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be re-
paired immediately. Do not continue to drive
under these circumstances! Contact an au-
thorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect mounting bolts or improperly
tightened mounting bolts can cause the
wheel to come off. This could cause an acci-
dent. Be sure to use the correct mounting
bolts.
Warning!
G
Use only genuine equipment
Mercedes-Benz wheel bolts. Other wheel
bolts may come loose.
Do not tighten the wheel bolts when the ve-
hicle is raised. Otherwise the vehicle could
tip over.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
80 lb-ft (110 Nm).

250 Practical hintsFlat tire

Detach the electric air pump.

Reinstall tire valve cap.

Stow the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.

Close the trunk lid.Storing collapsible spare wheel in
wheel well
Before you can store the spare wheel with
collapsible tire in the wheel well you have
to release the air pressure of the tire.

Unscrew valve stem removal tool,
which is part of the valve cap, from tire
valve.

Using the valve stem removal tool,
open tire valve slightly by turning the
tire valve insert counterclockwise to
release air pressure.

When the air pressure has been re-
leased, remove tire valve insert (pro-
tect it from dirt and sand) using the
previously removed tire valve cap.

Once all air is out of the tire, and the
tire has collapsed to its original shape,
reinstall the tire valve insert and valve
cap.

Place spare wheel in wheel well and
secure it with the pump holder.

Turn pump holder clockwise to its stop.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
Warning!
G
To prevent possible injury when unscrewing
air pump filler hose from tire valve after in-
flating the tire, use a rag since the tire valve
could be hot.

Battery
Batteries contain materials that can harm
the environment if disposed of improperly.
Large 12-volt storage batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnec-
tion):

Set the clock (
page 91).


Resynchronize the ESP
(page 202).


Re-enter the radio code (see radio
operating instructions).


Resynchronize side windows
(page 129).
