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 driving comfort
RSusceptibilitytodamage
\nWARNINGRisk 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 (→page 393).
RTirepressuretable onthe inside ofthe fuelfillerflap (→page 387).
Observethe maximum tire pressure(→page 399).
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 least three 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.
\nWARNINGRisk 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
\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.
