Triggering an automatic emergency call
RequirementsRThe ignition is switched on.
RThestarter battery is sufficientlycharged.
Ifrestraint systems such as airbags or Emer‐gencyTensioning Devices havebeen activatedafter an accident,the Mercedes-Benz emer‐gency call system may automatically initiate anemergency call.
The emergency call has been made:
RAvoice connection is madetothe Mercedes-Benz emergency call center.
RA messagewith accident data is transmittedtothe Mercedes-Benz emergency call center.
The Mercedes-Benz emergency call centercan transmitthevehicle position datatooneofthe emergency call centers.
The SOS button intheoverhead control panelflashes untilthe emergency call isfinished.
It is not possibletoimmediately end an auto‐matic emergency call.
If no connection can be madetothe emergencyservices either, a corresponding messageappearsinthe media display.
#Dialthe local emergency number onyourmobile phone.
If an emergency call has been initiated:
RRemain inthevehicle iftheroad and trafficconditions permityoutodo so until avoiceconnection is established withthe emer‐gency call center operator.
RBased onthe call,the operator decideswhether it is necessarytocallrescueteamsand/orthe policetothe accident site.
RIf novehicle occupant answers, an ambu‐lance is senttothevehicle immediately.

Notes onthe12V battery
&WARNINGRisk of an accident duetoworkcarried out incorrectly onthe bat‐tery
Workcarried out incorrectly onthe batterycan,forexample, leadtoa short circuit. Thiscan leadtofunctionrestrictions in safety-rel‐evant systems,forexamplethe lighting sys‐
tem, ABS (anti-lockbraking system) or ESP®
(ElectronicStability Program). The operatingsafety ofyourvehicle may berestricted.
You could lose control ofthevehicle inthefollowing situations:
Rwhen braking
Rintheevent of abruptsteering maneuversand/or whenthevehicle's speed is notadaptedtotheroad conditions
#Intheevent of a shortcircuit or a simi‐lar incident, contact aqualified special‐istworkshop immediately.
#Do not continue driving.
#Always haveworkonthe battery carriedout at aqualified specialistworkshop.
RFurther information on ABS (→page192)
RFurther information on ESP®(→page193)
For safetyreasons, Mercedes-Benzrecommendsthatyou onlyuse batteries which havebeentes‐ted and approvedforyourvehiclebyMercedes-Benz. These batteries provide increased impactprotectiontopreventvehicle occupants fromsuffering acid burns shouldthe battery be dam‐aged intheevent of an accident.

Notes onstarting assistance and oncharg‐ingthe12V battery
Vehicles with a lithium-ion batteryWhenchargingthe battery and duringstartingassistance, alwaysusethe jump-startconnec‐tion point inthe engine compartment.
*NOTEDamagetothe battery fromover‐voltage
Whencharging using a batterycharger with‐out a maximumchargingvoltage,the batteryorthe on-board electronics may be damaged.
#Only use batterychargerswith a maxi‐mumchargingvoltage of14.4V.
AllothervehiclesWhenchargingthe battery and duringstartingassistance, alwaysusethe jump-startconnec‐tion point inthe engine compartment.
*NOTEDamagingthe batterythroughovervoltage
Whencharging using a batterycharger with‐out a maximumchargingvoltage,the batteryorthevehicle electronics may be damaged.
#Only use batterychargerswith a maxi‐mumchargingvoltage of14.8V.
&WARNINGRisk ofexplosion fromhydro‐gengas igniting
A batterygenerateshydrogengas duringthecharging process. Ifthere is a short circuit orsparksstarttoform,there is a danger ofthehydrogengas igniting.
#Make surethatthe positiveterminal ofthe connected battery does not comeinto contact withvehicle parts.
#Never place metal objects ortools on abattery.
#When connecting and disconnectingthebattery,you must observethe descri‐bed orderforthe battery clamps.
Breakdown assistance421

#When givingstarting assistance, alwaysmake surethatyou onlyconnect bat‐teryterminals with identical polarity.
#Duringstarting assistance,you mustobservethe described orderfor con‐necting and disconnectingthe jumpercables.
#Do not connect or disconnectthe bat‐teryclamps whilethe engine isrunning.
&WARNINGRisk ofexplosion duringcharging process andstarting assistance
Duringthecharging process andstartingassistance,the battery mayrelease anexplo‐sivegas mixture.
#Avoidfire, openflames, creating sparksand smoking.
#Make surethatthere is sufficientventi‐lation duringthecharging process andduringstarting assistance.
#Do not leanover a battery.
&WARNINGRisk ofexplosion from a fro‐zen battery
A discharged battery may freeze attempera‐tures slightly aboveor below freezing point.
Duringstarting assistance or batterycharg‐ing, batterygas may bereleased.
#Alwaysthawa frozen batteryoutfirstbeforecharging it or performingstart‐ing assistance.
Ifthe indicator/warning lamps inthe instrumentcluster do not light up at lowtemperatures, it isverylikelythatthe discharged battery has fro‐zen. Inthis caseyou may neither jump-startthevehicle norchargethe battery.
The service life of a batterythat has beenthawed may be dramatically shortened. Thestartingcharacteristics may be impaired, espe‐cially at lowtemperatures.
It isrecommendedthatyou haveathawed bat‐terychecked at aqualified specialistworkshop.
