Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified new fuses having the correct amperage.
!Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the compo- nents on the circuit and their functions stop
operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. an authorized
Mercedes-Benz Center.
Before changing a fuse
X Secure the vehicle against rolling away (Y page 161).
X Switch off all electrical consumers.
X Turn the SmartKey to position 0in the igni-
tion lock and remove it ( Ypage 139).
or
X On vehicles with KEYLESS-GO, make sure
the ignition is switched off ( Ypage 140).
All indicator lamps in the instrument cluster
must be off.
The fuses are located in various fuse boxes:
R Fuse box in the engine compartment on the
left-hand side of the vehicle, when viewed
in the direction of travel
R Fuse box in the trunk
The fuse allocation chart is located in the
vehicle tool kit in the stowage compartment
under the trunk floor ( Ypage 294).

Mounting a new wheel
GWARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheelbolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event ofdamage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always pay attention to the instructions and
safety notes in the "Changing a wheel" sec-
tion ( Ypage 334).
Only use wheel bolts that have been designed for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz vehicles and the
respective wheel.
!To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
X Clean the wheel and wheel hub contact
surfaces.
X Slide the wheel to be mounted onto the
alignment bolt and push it on.
X Tighten the wheel bolts until they are fin-ger-tight.
X Unscrew the alignment bolt.
X Tighten the last wheel bolt until it is finger-
tight.
X Vehicles with a collapsible spare wheel:
inflate the collapsible spare wheel( Y page 344). Only then lower the vehicle.
Lowering the vehicle
GWARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
X Turn the crank of the jack counter-clock-
wise until the vehicle is once again standing
firmly on the ground.
X Place the jack to one side.
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated ( :
to A ). The specified tightening torque is
96 lb-ft (130 Nm) .
X Turn the jack back to its initial position.
X Stow the jack and the rest of the vehicle
tools in the trunk again.

Wheels and tires

found on the wheel or under "Technical data"( Y page 346).
An emergency spare wheel may also be
mounted against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
iWhen you are driving with the collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning sys-
tem/the tire pressure monitor when the
damaged wheel has been replaced with a
new wheel.
Vehicles with tire pressure monitor:
after mounting an emergency spare wheel,
the system may still display the tire pres-
sure of the removed wheel for a few
minutes. The value displayed for the moun- ted emergency spare wheel is not the sameas the current tire pressure of the emer-
gency spare wheel.
Removing the emergency spare wheel
(Example)
The collapsible spare wheel can be found in
the stowage well under the trunk floor. X
Lift and remove the reversible floor panel in
the trunk ( Ypage 260).
X Turn retaining screw ;counter-clockwise
and remove it.
X Remove collapsible spare wheel :.
Always observe the instructions and safety
notes in the "Mounting a wheel" section( Y page 335).
Stowing the emergency spare wheel
!
Only place the collapsible spare wheel in
the vehicle when it is dry. Otherwise, mois-
ture may get into the vehicle.
Take the following steps to stow a used col-
lapsible spare wheel. Otherwise, the collaps-
ible spare wheel will not fit in the trunk in the
intended manner. Mercedes-Benz recom-
mends that you have this work carried out at
a qualified specialist workshop.
X Unscrew the valve cap from the valve.
X If possible, unscrew the valve insert from
the valve and release the air.
iFully deflating the tires can take a few
minutes.
X Screw the valve insert back into the valve.
X Screw the valve cap back on.
X Pull the protective sheet provided with the
spare wheel over the collapsible spare
wheel.
X Stow the collapsible spare wheel in the
emergency spare wheel well under thetrunk.
X Use the retaining screw to pierce the pro-
tective sheet and fasten the collapsible
spare wheel in place.
Inflating the collapsible spare wheel
!
Inflate the collapsible spare wheel using
the tire inflation compressor before lower-
ing the vehicle. The wheel rim could other-
wise be damaged.
