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.
\nWARNINGRisk 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.
\nWARNINGRisk 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.

Observethefollowing points duringstartingassistance and whenchargingthe battery:
ROnly use undamaged jumper cables/charg‐ing cables with a sufficient cross-section andinsulatedterminal clamps.
RNon-insulated parts oftheterminal clampsmust not come into contact withother metalparts whilethe jumper cable/charging cableis connectedtothe battery/jump-startcon‐nection point.

Tirepressure
Notes on tire pressure
\nWARNINGRisk of accident duetoinsuf‐ficient orexcessive tire pressure
Underinflated oroverinflated tires posethefollowingrisks:
RThe tires may burst, especially astheload andvehicle speed increase.
RThe tires maywearexcessively and/orunevenly,which maygreatlyimpair tiretraction.
RThe drivingcharacteristics, aswell assteering and braking, may be greatlyimpaired.
Comply withtherecommended tirepressure andcheckthe tire pressure ofall tires includingthe spare wheelregu‐larly:
Rat least once a month
Rwhenthe loadchanges
Rbefore embarking on a longer journey
Rif operating conditionschange, e.g. off-road driving
Adjustthe tire pressure as necessary.
Driving withtire pressurethat istoo high ortoolow can:
RShortenthe service life ofthe tires.
RCause increased tire damage.
RAdversely affect drivingcharacteristics andthus driving safety,e.g. dueto hydroplaning.
\nWARNINGRisk of an accident duetoinsufficient tire pressure
Tires with pressurethat istoo low canover‐heat and burstas aresult.
In addition,theyalso suffer fromexcessiveand/or irregularwear, which can significantlyimpairthe braking properties andthe han‐dlingcharacteristics.
Avoidexcessively low tire pressures inallthe tires, includingthe spare wheel.
Tirepressure which istoo low can cause:
RTiredefects as aresult ofoverheating
RImpaired handlingcharacteristics
RIrregularwear
RIncreased fuel consumption
\nWARNINGRisk of accident fromexces‐sive tire pressure
Tires withexcessively high pressure canburstbecausetheyare damaged more easilybyhighwayfill, pot holesetc.
In addition,theyalso suffer from irregularwear, which can significantly impairthe brak‐ing properties andthe handlingcharacteris‐tics.
Avoidexcessively high tire pressures inallthe tires, includingthe spare wheel.
Excessively high tire pressure canresult in:
RIncreased braking distance
RImpaired handlingcharacteristics
RIrregularwear

The systemchecksthe tire pressure andthe tiretemperature ofthe tires installed onthevehiclebymeans of a tire pressuresensor.
New tire pressure sensors, e.g. in winter tires,are automaticallytaught-in duringthefirst jour‐neytheyare used.
The tire pressure andthe tiretemperatureappear inthe multifunction display(→page 390).
Ifthere is a substantial pressure loss or ifthetiretemperature isexcessive,you will bewarnedinthefollowingways:

The tire pressuremonitoring system is only anaid. It isthe driver'sresponsibilitytosetthe tirepressuretotherecommended cold tire pressuresuitableforthe operating situation. Setthe tirepressurefor cold tires using a tire pressuregauge.Notethatthe correct tire pressureforthecurrent operating situation mustfirst betaught-intothe tire pressure monitoring system.
In most cases,the tire pressure monitoring sys‐tem will automaticallyupdatethe newreferencevalues afteryou havechangedthe tire pressure.You can, however,also updatethereferenceval‐uesbyrestartingthe tire pressure monitoringsystem manually (→page 391).
System limitations
The system may be impaired or may not functioninthefollowing situations:
RIfthe tire pressure is set incorrectly
RIfthere is a sudden pressure loss caused,forexample,byaforeign object penetratingthetire
RIfthere is a malfunction causedbyanotherradio signal source

Therelative performance of tires depends uponthe actual conditions oftheir use, however,andmay depart significantly fromthe norm duetovariations in driving habits, service practices anddifferences inroadcharacteristics and climateconditions.
Tractiongrade
\nDANGERRisk of accident duetoinade‐quate traction
The tractiongrade assignedtothis tire isbased onstraight-ahead braking tractiontests, and does not include either accelera‐tion, cornering,hydroplaning or peak tractioncharacteristics.
Always adaptyour drivingstyle anddrive at a speedtosuitthe prevailingtraffic andweather conditions.
NOTEDamagetothe drivetrain fromwheelspin
Avoid wheelspin.
The traction grades – from highesttolowest –are AA,A,B and C. Those gradesrepresentthetire's abilitytostop onwet pavement as meas‐ured under controlled conditions on specifiedgovernmenttestsurfaces made of asphalt andconcrete.
Temperaturegrade
\nWARNINGRisk of accident from tireoverheating and tirefailure
Thetemperature gradeforthis tire is estab‐lishedfor a tirethat is properly inflated andnotoverloaded. Excessive speed, underinfla‐tion, orexcessive loading, either separatelyor in combination, can causeexcessive heatbuild-up and possible tirefailure.
Observetherecommended tire pres‐sures andregularlycheckthe tire pres‐
sure of all tires includingthe sparewheel.
Adjustthe tire pressure as necessary.
Thetemperature grades are A (the highest), Band C. Theyrepresentthe tire'sresistancetothegeneration of heat and its abilitytodissipateheat whentested under controlled conditions ona specified indoor laboratorytestwheel. Sus‐tained hightemperature can causethe materialofthe tiretodegenerate andreduce tire life, andexcessivetemperature can leadtosudden tirefailure. Grade C correspondstoa level of per‐formance which all passenger car tires mustmeet undertherequirements ofthe US Depart‐ment ofTransportation.

\nWARNINGRisk of an accident duetovapor pocketsforming inthe brake sys‐tem
The brakefluid constantly absorbs moisturefromthe air. This lowersthe boiling point ofthe brakefluid. Ifthe boiling point istoo low,vapor pockets mayforminthe brake systemwhenthe brakes are applied hard.
This causesthe braking effecttobeimpaired.
