On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with
wrench1).
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.1Jack take-up bracket
2Jack
Place jack2 on firm ground.
Position jack2 under take-up
bracket1 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an
incline.
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.

428 Practical hintsFusesThe electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Center.
The following aids are available to help you
replace fuses:
Fuse chart
The fuse chart is located in the fuse box
in the passenger compartment
(page 429). The fuse chart explains
the fuse allocation and fuse amperag-
es.
Spare fuses
Spare fuses are located in the vehicle
tool kit in the trunk (
page 393).
Fuse extractor
The fuse extractor is located in the ve-
hicle tool kit in the trunk (
page 393).The electrical fuses are located in different
fuse boxes:
Main fuse box in passenger compart-
ment (
page 429)
Fuse box in trunk (
page 429)
Before replacing fuses:
Apply the parking brake (
page 59).
Make sure the gear selector lever is set
to position P (
page 171).
Turn off all electrical consumers.
Turn off the engine (
page 60).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door.
Warning!
G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than ap-
proved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an
authorized Mercedes-Benz Center.i
A blown fuse must be replaced by an appro-
priate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart.
Any Mercedes-Benz Center will be glad to advise
you on this subject.
