Securingthechildrestraint system withtheseat belt onthe front passenger seat
When installing a belt-securedchildrestraintsystem onthe front passenger seat, alwaysobservethefollowing:
sObservethechildrestraint system manufac‐turer's installation and operating instruc‐tions.
sWhen using aforward-facingchildrestraintsystem in Group I:removethe headrestraint fromtherespective seat, if possi‐ble.
Whenyouremovethechildrestraint sys‐tem, installthe headrestraint again immedi‐ately and adjust allthe headrestraints cor‐rectly.
sThe backrestoftheforward-facingchildrestraint system must lie asflat as possibleagainstthe backrest ofthe front passengerseat.
sFor certainchildrestraint systems inweightgroup II or III,there may berestrictions inthe maximum size setting, e.g. duetopossi‐ble contact with theroof.
sThechildrestraint system must not be putunderstrain betweentheroof andthe seatcushion and/or be installedfacingthewrong direction.Adjustthe seat backrestinclination accordingly.
sThechildrestraint system must not be putunderstrainbythe headrestraints.Adjustthe headrestraints accordingly.
sNever place objects under or behindthechildrestraint system, e.g. cushions.
The seat belt onthe front passenger side isequipped with a special seatbeltretractor.
When activated,the special seatbeltretractorensuresthatthe seat belt does not slacken oncethechildrestraint system is secured(→page 53).
Setthe front passenger seat asfar back aspossible and movethe seat intothe highestposition.
Fullyretractthe seat cushion length adjust‐ment.
Adjustthe seat cushion inclination sothatthe front edge ofthe seat cushion is inthe
highest position andtherear edge oftheseat cushion is inthe lowestposition.
Setthe seat backresttoan almostverticalposition.
Installthechildrestraint system.The entire base ofthechildrestraint systemmust alwaysrestonthe seat cushion ofthefront passenger seat.
Always make surethatthe shoulder beltstrap is correctlyrouted fromthe seat beltoutlet ofthevehicletothe shoulder beltguide onthechildrestraint system.The shoulder beltstrap must beroutedfor‐wards and downwards fromthe seat belt out‐let.
If necessary,adjustthe seat belt outlet andthe front passenger seat accordingly.

The tire pressuretable shows therecommendedtire pressurefor all tires approvedforthisvehi‐cle. Therecommended tire pressures applyforcold tires undervarious operating conditions, i.e.loading and/or speed ofthevehicle.
If one or more tire sizes precede a tire pressure,the tire pressure informationfollowing is onlyvalidforthose tire sizes.
The load conditions "partially laden" and "fullyladen" are defined inthetablefor different num‐bersof passengers and amounts of luggage. Theactual number of seats may differ fromthis.
Some tire pressuretables only showtherimdiameter instead ofthe completetire size, e.g.R18. Therim diameter is part ofthe tire size andcan befound onthe tire sidewall (→page 400).
Be suretoalso observethefollowing furtherrelated subjects:

Checking tire pressures manually
Readthe tire pressureforthe current operat‐ing conditions fromtheTireand LoadingInformation placard orthe tire pressuretable. Observethe notes on tire pressure.
Removethevalve cap ofthe tiretobechecked.
Pressthe tire pressuregauge securely ontothevalve.
Readthe tire pressure.
Ifthe tire pressure is lowerthantherecom‐mendedvalue, increasethe tire pressuretotherecommendedvalue.
Ifthe tire pressure is higherthantherecom‐mendedvalue,release air.Todo so, pressdownthe metal pin inthevalve, e.g. usingthe tip of a penforexample. Thencheckthetire pressureagain usingthe tire pressuregauge.

Tirepressure monitoring system
Function ofthe tire pressure monitoring sys‐tem
\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.
