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.
Breakdown assistance419

#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.

Replacing the12V battery
#Observethe notes onthe12V battery(→page419).
Mercedes-Benzrecommendsthatyou havethe12V batteryreplaced at aqualified specialistworkshop, e.g. at an authorized Mercedes-BenzCenter.
Observethefollowing notes ifyouwanttoreplacethe batteryyourself:
RAlwaysreplace afaulty batterywith a batterywhich meetsthe specificvehiclerequire‐ments.
Thevehicle is equipped with anAGMtechnol‐ogy battery (Absorbent Glass Mat) or a lith‐ium-ion battery.Fullvehicle functionality is
only guaranteed with anAGM battery or lith‐ium-ion battery.For safetyreasons,Mercedes-Benzrecommendsthatyou onlyuse batteries which havebeentested andapprovedforyourvehiclebyMercedes-Benz.
RCarryover detachable parts, such asventhoses, elbowfitting orterminal coversfromthe battery beingreplaced.
RMake surethatthevent hose is alwayscon‐nectedtothe original opening onthe side ofthe battery.
Install anyexisting or supplied cell caps.
Otherwise,gases or battery acid couldescape.

&WARNINGRisk of accident causedbyrepeated drop in tire pressure
Ifthe tire pressure dropsrepeatedly,thewheel,valve or tire may be damaged.
Insufficient tire pressure can causethe tirestoburst.
#Inspectthe tirefor signs offoreignobjects.
#Check whetherthe wheel orvalve has aleak.
#Ifyou are unabletorectifythe damage,contact aqualified specialistworkshop.
You canfind information on tire pressureforthevehicle'sfactory-installed tires onthefollowinglabels:
RTireand Loading Information placard ontheB‑pillar ofyourvehicle (→page442).
RTirepressuretable onthe inside ofthe fuelfillerflap (→page 437).
Observethe maximum tire pressure(→page448).
Use a suitable tire pressuregaugetocheckthetire pressure. The outer appearance of a tiredoes not permit anyreliable conclusion aboutthe tire pressure.
Vehicles with a tire pressure monitoring sys‐tem:You can alsocheckthe tire pressure usingthe on-board computer.
Only correct tire pressure whenthe tires arecold. Conditionsfor cold tires:
RThevehicle has been parked withthe tiresout of direct sunlightfor at leastthree hours.
RThevehicle has traveled lessthan 1 mile(1.6 km).
Arise inthe tiretemperature of18°F (10 °C)increasesthe tire pressurebyapprox.10kPa(0.1 bar/1.5 psi).Takethis into account whencheckingthe tire pressure ofwarmtires.
The tire pressure recommendedfor increasedload/speed inthe tire pressuretable can affecttheride comfort.
&WARNINGRisk of accident from unsuita‐ble accessories onthe tirevalves
Ifyou mount unsuitable accessories ontotirevalves,the tirevalves may beoverloaded andmalfunction, which can cause tire pressureloss.Tirepressure monitoring systemsforretrofitting will causethe tirevalvetoremainopen. This can alsoresult in tire pressureloss.
#Only screwstandardvalve caps orvalvecaps specifically approvedbyMercedes-Benzforyourvehicle ontothe tirevalve.

Tirepressure monitoring system
Function ofthe tire pressure monitoring sys‐tem
&DANGERRisk of accident duetoincor‐rect tire pressure
Every tire, includingthe spare (if provided),should bechecked when cold at least once amonth and inflatedtothe pressurerecom‐mendedbythevehicle manufacturer (seeTireand Loading Information placard ontheB-pillar onthe driver’sside orthe tire pres‐sure label onthe inside ofthe fuelfillerflapofyourvehicle). Ifyourvehicle has tires of adifferent sizethanthe size indicated ontheTireand Loading Information placard orthe
tire pressuretable,you needtodeterminethe proper tire pressureforthose tires.
As an added safetyfeature,yourvehicle hasbeen equipped with a tire pressure monitor‐ing system (TPMS)that illuminates a low tirepressure indicator lamp when one or more ofyour tires are significantly underinflated.Accordingly, ifthe low tire pressure indicatorlamp lights up,you shouldstop andcheckyour tires as soon as possible, and inflatethemtothe proper pressure. Driving on asignificantly underinflated tire causesthe tiretooverheat and can leadtotirefailure.Underinflation also increases fuel consump‐tion andreduces tire tread life, and mayaffectthevehicle's handling and braking abil‐ity. Please notethatthe TPMS is not a substi‐tutefor proper tire maintenance, and it isthedriver'sresponsibilitytomaintain correct tirepressure,even if underinflation has notreachedthe leveltotrigger illumination ofthe TPMS low tire pressure indicator lamp.
Yourvehicle has also been equipped with aTPMS malfunction indicatortoindicate when
the system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure indicator lamp. Whenthe system detects a malfunction,the indica‐tor lamp willflashfor approximatelya minuteandthenremain continuously illuminated.This sequence will continue upon subsequentvehiclestart-ups as long asthe malfunctionexists.
Whenthe malfunction indicator is illumina‐ted,the system may not be abletodetect orsignal low tire pressure as intended. TPMSmalfunctions may occurfor avariety ofrea‐sons, includingthe installation of incompati‐blereplacement or alternate tires or wheelsonthevehiclethat preventthe TPMS fromfunctioning properly.
Alwayscheckthe TPMS malfunctionwarninglamp afterreplacing one or more tires orwheels onyourvehicletoensurethatthereplacement or alternate tires and wheelsallowthe TPMStocontinuetofunction prop‐erly.
