XMake sure the vehicle is stationary and the
ignition is switched off.
XTurn the SmartKey to position2in the
ignition lock (Ypage 147).
Use the SmartKey instead of the Start/
Stop button on vehicles with KEYLESS-GO.
XDepress and hold the brake pedal.
XShift the automatic transmission to
positionN.
XRelease the brake pedal.

You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.

The water jet fromacircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components.
Componentsdamaged in this way may fail
unexpectedly. There isarisk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced
immediately.
!Always maintainadistance of at least

Maintenance and care

ROnly jump-start from batteries witha12Vvoltage rating.
ROnly use jumper cables which haveasufficient cross-section and insulated terminal clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start connected
forafew minutes before attempting to start. This charges the battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
Rthe jumper cables are not damaged.
Rwhen the jumper cables are connected to the battery, uninsulated sections of the terminal
clamp do not come into contact with other metal sections.
Rthe jumper cables cannot come into contact with parts which can move when the engine
is running, such as the V-belt pulley or the fan.
XApply the parking brake firmly.
XShift the transmission to positionP.
XSwitch off all electrical consumers (e.g. radio, blower, etc.).
XOpen the hood.

XSlide coverof positive terminalin the direction of the arrow.
XConnect positive terminalon your vehicle to positive terminal$of donor battery%
using the jumper cable, always begin with positive terminalon your own vehicle first.
XStart the engine of the donor vehicle and run it at idling speed.
XConnect negative terminal!of donor battery%to ground pointof your vehicle using

Fuses
Important safety notes
GWARNING
If you manipulate or bridgeafaulty fuse or if
you replace it withafuse withahigher
amperage, the electric cables could be
overloaded. This could result inafire. There
isarisk 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-Benzvehicles and which
have the correct fuse ratingfor the system
concerned. Otherwise, componentsor
systems could be damaged.
The fuses in your vehicle serve to close down
faulty circuits. Ifafuse blows,all the
componentsonthecircuit and their functions
stop operating.
Blown fusesmust be replacedwith fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.
Ifanewly inserted fuse also blows, have the
cause traced and rectified ataqualified
specialist workshop, e.g. an authorized
Mercedes-BenzCenter.

Onaslippery surface,anon-slip underlay
must be used, e.g. rubber mats.
Rdo not use wooden blocks or similar
objectsasajack underlay.Otherwise, the
jackwill not be able to achieveits load-
bearingcapacity due to the restricted
height.
