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.

\nDANGERRisk 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 asignificantlyunderinflated 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.

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 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:

Determiningthe maximum permissible load
Thefollowingsteps havebeen developed asrequired of all manufacturers underTitle 49,Code ofU.S.FederalRegulations,Part575, pur‐suanttothe "NationalTraffic and MotorVehicleSafetyAct of1966".
Step 1:locatethestatement "The combinedweight of occupants and load should neverexceed XXXkgor XXX lbs." ("The combinedweight of occupants and load should neverexceed XXXkgor XXX lbs.") onyourvehicle'sTireand Loading Information placard.
Step 2:determinethe combinedweight ofthe driver and passengersthat will be travel‐ing inyourvehicle.
Step 3:subtractthe combinedweight ofthedriver and passengers from XXXkgorXXX lbs.
Step 4:theresultingfigure equalsthe per‐missible cargo and luggage load capacity.Forexample: If "XXX" equals1400 lbs andtherearefiveoccupants inyourvehicle with aweight of150 lbs each,the maximum cargoand luggage load capacity is 650 lbs (1400 -750 (5 x150) = 650 lbs).
Step 5:determinethe combinedweight ofluggage and loadthatthevehicle will be car‐rying.For safetyreasons,thisweight may notsafelyexceedtheavailable cargo and lug‐gageload capacity calculated instep 4.
Even ifyou havecalculatedthetotal load care‐fully,you shouldstill make surethatthe maxi‐mum permissible gross mass andthe maximumpermissible axle load ofyourvehicle are notexceeded. Details can befound onthevehicleidentification plate.
Haveyour loadedvehicle – including driver,occupants and load –weighed on avehicleweighbridge.The measuredvalues may notexceedthemaximum permissiblevaluesstated onthevehicle identification plate.
