and with the specified watt rating.
Switch lights off before changing a bulb
to prevent short circuits.
Always use a clean lint-free cloth when
handling bulbs.

Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Bi-Xenon lamps,
it is dangerous to replace the bulb or repair
the lamp and its components. We recom-
mend that you have such work done by a
qualified technician.

Removing the wheel
1Alignment bolt
Unscrew the upper-most wheel bolt
and remove.
Replace this wheel bolt with alignment
bolt1 supplied in the tool kit.
Remove the remaining bolts.
Remove the wheel.Mounting the Minispare wheel
Clean contact surfaces of wheel and
wheel hub.
Guide the spare wheel onto the align-
ment bolt and push it on.
Insert wheel bolts and tighten them
slightly.
Warning!
G
Position the jack only on the jack take-up
brackets designed for this purpose.
If the jack is not properly positioned, the ve-
hicle may slip off of the jack.Warning!
G
The jack is intended only for lifting the vehi-
cle briefly for wheel changes. It is not suited
for performing maintenance work under the
vehicle. Never lie down under the raised ve-
hicle. Do not start the engine when the vehi-
cle is raised.
!Do not place wheel bolts in sand or dirt.
This could result in damage to the bolt
and wheel hub threads.
!To avoid paint damage, place wheel flat
against hub and hold it there while in-
stalling first wheel bolt.

Flat tire
Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.In the case of a flat tire, you may tempo-
rarily use the Minispare* wheel when ob-
serving the following restrictions:
Do not exceed a vehicle speed of
50 mph (80km/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.
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. They are identi-
fied by the Mercedes star. 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
The dimensions of the Minispare* wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare*
wheel mounted.
The spare wheel should only be used tempo-
rarily, and replaced with a regular road
wheel as quick as possible.

Batteries
Reconnecting the batteries
Turn off all electrical consumers.
Connect the positive lead and fasten its
cover.
Connect the negative lead.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.Warning!
G
Never charge a battery while still installed in
the vehicle. Gases may escape during charg-
ing and cause explosions that may result in
paint damage, corrosion or personal injury.!NEVER invert the terminal connections!
The battery, its filler caps and the vent
tube must always be securely installed
when the vehicle is in operation.
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnec-
tion):
Set the clock (
page 136) (vehi-
cles with COMAND*: see COMAND
operator’s manual).
Resynchronize the front seat head
restraints (
page 104).
Resynchronize the ESP
(page 75).
Re-enter the radio code (see radio
operating instructions).
Resynchronize the side windows
(page 186).
Resynchronize the sliding/pop-up
roof* (
page 189).
