2019 MERCEDES-BENZ GLA fuel cap

Recommended tire pressures
The recommended tire pressure applies to thetires mounted at the factory.
The Tire and Loading Information placard con-tains the recommended tire pressures for coldtires on a fully loaded vehicle and for the maxi-mum permissible vehicle speed.
The tire pressure table contains the recom-mended pressures for cold tires for variousoperating conditions, i.e. differing load andspeed conditions.
Increased vehicle weight due to optional
equipment
The combined weight of all standard andoptional equipment available for the vehicle,regardless of whether it is actually installed onthe vehicle or not.
Rim
This is the part of the wheel on which the tireis mounted.
GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weightrating. The actual load on an axle must neverexceed the gross axle weight rating. The grossaxle weight rating can be found on the vehicleidentification plate on the B-pillar on the driv-er's side.
Speed rating
The speed rating is part of the tire identifica-tion. It specifies the speed range for which thetire is approved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weightof the vehicle including fuel, tools, the sparewheel, accessories installed, occupants, lug-gage and the drawbar noseweight, if applica-ble. The gross vehicle weight must not exceedthe gross vehicle weight rating GVWR as speci-fied on the vehicle identification plate on theB-pillar on the driver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible grossweight of a fully loaded vehicle (the weight ofthe vehicle including all accessories, occu-pants, fuel, luggage and the drawbar nose-weight, if applicable). The gross vehicle weightrating is specified on the vehicle identificationplate on the B-pillar on the driver's side.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optionalequipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-sponds to 1 psi. Another unit for tire pressureis bar. 100 kilopascals (kPa) are the equivalentof 1 bar.
Load index
In addition to the load-bearing index, the loadindex may also be imprinted on the sidewall ofthe tire. This specifies the load-bearing capa-city more precisely.
Curb weight
The weight of a vehicle with standard equip-ment including the maximum capacity of fuel,oil and coolant. It also includes the air-condi-tioning system and optional equipment if theseare installed in the vehicle, but does notinclude passengers or luggage.
Maximum load rating
The maximum tire load is the maximum per-missible weight in kilograms or lbs for which atire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for onetire.
Maximum load on one tire
Maximum load on one tire. This is calculatedby dividing the maximum axle load of one axleby two.
PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire widthin percent.
Tire pressure
This is pressure inside the tire applying an out-ward force to each square inch of the tire'ssurface. The tire pressure is specified in

Fuel
Important safety notes
GWARNING
Fuel is highly flammable. Risk of fire and
explosion by improper handling of fuel.
You must avoid fire, open flames, smoking
and creating sparks. Switch off the ignition
before refueling and, if present, switch off
the auxiliary heating.
GWARNING
Fuels are toxic and harmful to health. There
is a risk of injury.
You must avoid fuels coming into contact
with skin, eyes and clothes or being swal-
lowed.
Do not inhale the fuel vapors. Keep children
away from fuels.
Keep doors and windows closed during the
refueling process.
If you or others come into contact with fuel,
observe the following points:
RImmediately rinse the fuel off your skin
with soap and water.
RIf you get fuel into your eyes, immediately
rinse your eyes throughly with clean
water. Seek medical attention immedi-
ately.
RSeek medical attention immediately if fuel
has been swallowed. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.

Fuel grade
!Do not use diesel to refuel vehicles with agasoline engine. Do not switch on the igni-tion if you accidentally refuel with the wrongfuel. Otherwise, the fuel will enter the fuelsystem. Even small amounts of the wrongfuel could result in damage to the fuel sys-tem and the engine. Notify a qualified spe-cialist workshop and have the fuel tank andfuel lines drained completely.
!Only refuel using unleaded premium gradegasoline with at least 91 AKI/95 RON.
iE10 fuel contains up to 10% bioethanol.Your vehicle is E10-compatible. You canrefuel your vehicle using E10 fuel.
!Only use the fuel recommended. Operatingthe vehicle with other fuels can lead to dam-age to the fuel system, engine and exhaustsystem.
!Do not use the following:
RGasoline with more than 10% ethanol
RE100 (100% ethanol)
RGasoline with methanol
RM100(100% methanol)
RGasoline with metalliferous additives
RDiesel

Do not mix such fuels with the fuel recom-mended for your vehicle.
!To ensure the longevity and full perform-ance of the engine, only premium-gradeunleaded gasoline must be used.
If standard unleaded gasoline is unavailableand you have to refuel with unleaded gaso-line of a lower grade, observe the followingprecautions:
ROnly fill the fuel tank to half full with regu-lar unleaded gasoline and fill the rest withpremium-grade unleaded gasoline as soonas possible.
RDo not drive at the maximum speed.
RAvoid sudden acceleration and enginespeeds over 3,000 rpm.
You will usually find information about the fuelgrade on the fuel pump. If you cannot find thelabel on the fuel pump, ask the gas stationstaff.
iFor further information, consult a qualifiedspecialist workshop or visithttp://www.mbusa.com (USA only).
GLA 250, GLA 250 4MATIC:as a temporarymeasure, if the recommended fuel is not avail-able, you may also use regular unleaded gaso-line with an octane rating of 88 AKI/93 RON.
All other models:as a temporary measure, ifthe recommended fuel is not available, youmay also use regular unleaded gasoline withan octane rating of 87 AKI/91 RON. This mayreduce engine performance and increase fuelconsumption. Avoid driving at full throttle andsudden acceleration. Never refuel using gaso-line with a lower AKI.
iThe fuels you can use in your vehicle maydiffer from the information in the Operator'sManual depending on the country. The fuelsthat have been approved for your vehiclecan be found on the instruction label on theinside of the fuel filler flap.
Information on refueling (Ypage 143).
Additives
!Operating the engine with fuel additivesadded later can lead to engine failure. Donot mix fuel additives with fuel. This doesnot include additives for the removal andprevention of residue buildup. gasoline mustonly be mixed with additives recommendedby Mercedes-Benz. Comply with the instruc-
tions for use on the product label. Moreinformation about recommended additivescan be obtained from any authorizedMercedes-Benz Center.
Mercedes-Benz recommends that you usebranded fuels that have additives.
The fuel quality available in some countriesmay not be sufficient. Residue could build upin the fuel injection system as a result. In suchcases, and in consultation with an authorizedMercedes-Benz Center, the fuel may be mixedwith the cleaning additive recommended byMercedes-Benz. You must observe the notesand mixing ratios specified on the container.
Engine oil
General notes
!Do not use engine oil or an oil filter withspecifications deviating from thoseexpressly required for the prescribed serviceintervals. Do not change the engine oil or oilfilter in order to set replacement intervalslonger than those prescribed. This couldotherwise cause damage to the engine orexhaust gas aftertreatment.
Follow the instructions on the service inter-val display for changing the engine oil. Thiscould otherwise cause damage to theengine or exhaust gas aftertreatment.
When handling engine oil, observe the impor-tant safety notes on service products(Ypage 334).
The engine oils are matched to the perform-ance of Mercedes-Benz engines and serviceintervals. You should therefore only use engineoils and oil filters that are approved for vehi-cles with maintenance systems.
