Insert electrical plug4 into the vehi-
cle cigarette lighter socket
(page 258).
Turn the SmartKey in the starter switch
to position1 (
page 36).
Press I on electric air pump switch8.
The electric air pump should now
switch on and inflate the tire.After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose can become hot during inflation.
Please exercise appropriate caution.
If this tire inflation pressure is not at-
tained, turn off the electric air pump,
detach the filler hose from the tire
valve, and drive vehicle back and forth
very slowly approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.
Unscrew the air pump’s air hose5
from flange6 of the TIREFIT contain-
er.
Screw air hose5onto tire valve7.
Inflate the tire again.
Warning!
G
Observe safety instructions on air pump la-
bel.
!Do not operate the electric air pump
longer than 8 minutes without interrup-
tion. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.

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 spare 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.
!Do not place wheel bolts in sand or dirt.
This could result in damage to the bolt
and wheel hub threads.
Warning!
G
Vehicles with collapsible tire:
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
pump (
page 427)
before
lowering the
vehicle.
!To avoid paint damage, place wheel flat
against hub and hold it there while in-
stalling first wheel bolt.
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
repaired immediately. Do not continue to
drive under these circumstances! Contact
an authorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident. Be
sure to use the correct wheel bolts.

Vehicles with collapsible tire:
Continue the procedure by following
the instructions under “Inflating the
collapsible tire” and then “Lowering the

Screw union nut5 onto the tire valve.
Insert electrical plug3 into vehicle
cigarette lighter socket (
page 258).
Turn the SmartKey in the starter switch
to position1.
or
Press the KEYLESS-GO* start/stop
button on the gear selector lever once
without depressing the brake pedal.
Press I on electric air pump switch2.
The electric air pump should now
switch on and inflate the tire.
Inflate the tire to approximately 51 psi
(3.5 bar).
This takes about 5 minutes for the col-
lapsible tire. Air hose4 and union
nut5 can become hot during infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.
Press 0 on electric air pump switch2.
Turn the SmartKey in the starter switch
to position0.
or
Press KEYLESS-GO* start/stop button
on the gear selector lever twice without
depressing the brake pedal.
The electric air pump should now be
switched off.
If the tire inflation pressure is above
51 psi (3.5 bar), release excess tire in-
flation pressure using the vent screw.
Detach the electric air pump.
Stow electrical plug3 and air hose4
behind flap1 and place the air pump
back in the trunk.
!Do not operate the air pump longer
than 8 minutes without interruption.
Otherwise it may overheat.
You may operate the air pump again
after it has cooled off.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured 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.

Always make sure the jumper cables
are not on or near pulleys, fans or other
parts that move when the engine is
started or running.
The main battery is located in the trunk un-
derneath the luggage box (
page 401).
Make sure the two vehicles do not
touch.
Turn off all electrical consumers.
Apply parking brake.
Shift gear selector lever to positionP.
Connect positive terminals1 and3
of the batteries with the jumper cable.
Clamp cable to charged battery3
first.
1Positive terminal of discharged battery
2Negative terminal of discharged bat-
tery
3Positive terminal of charged battery
4Negative terminal of charged battery
Start engine of the vehicle with the
charged battery and run at idle speed.
Connect negative terminals4 and2
of the batteries with the jumper cable.
Clamp cable to charged battery4
first.
Start the engine of the disabled vehi-
cle.
Now you can again turn on the electrical
consumers. Do not turn on the lights under
any circumstances.
Remove the jumper cables first from
negative terminals2 and4 and then
from positive terminals1 and3.
Now you can turn on the lights.
Have the battery checked at the near-
est authorized Mercedes-Benz Center.
Warning!
G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 299).
!Never invert the terminal connections!
iThe message
Malfunction - electric
consumers switched off
may appear
in the instrument cluster. It will disap-
pear as soon as the battery is suffi-
ciently charged.
