ESP MERCEDES-BENZ GLA 2019 Owners Manual

which have been approved by Mercedes-Benz specifically for your vehicle.
These tires have been specially adapted foruse with the control systems, such as ABS
or ESP®, and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended(tires featuring run-flat characteristics)
RMO1 = Mercedes-Benz Original (only cer-tain AMG tires)
Mercedes-Benz Original Extended tires mayonly be used on wheels that have been spe-cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories testedand approved by Mercedes-Benz. Certaincharacteristics, e.g. handling, vehicle noiseemissions or fuel consumption, may other-wise be adversely affected. In addition,when driving with a load, tire dimension var-iations could cause the tires to come intocontact with the bodywork and axle compo-nents. This could result in damage to thetires or the vehicle.
Mercedes-Benz accepts no liability for dam-age resulting from the use of tires, wheelsor accessories other than those tested andapproved.
Information on tires, wheels and approvedcombinations can be obtained from anyqualified specialist workshop.
!Retreaded tires are neither tested nor rec-ommended by Mercedes-Benz, since previ-ous damage cannot always be detected onretreaded tires. As a result, Mercedes-Benzcannot guarantee vehicle safety if retreadedtires are mounted. Do not mount used tiresif you have no information about their previ-ous usage.
The recommended pressures for various oper-ating conditions can be found:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side
Rin the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-sures under various operating conditions(Ypage 307).
Check tire pressures regularly, and only whenthe tires are cold. Comply with the mainte-nance recommendations of the tire manufac-turer in the vehicle document wallet.
Notes on the vehicle equipment – alwaysequip the vehicle:
Rwith tires of the same size on a given axle(left and right)
Rwith the same type of tire (summer tires,MOExtended tires, winter tires)
Exception: it is permissible to install a differ-ent type or make in the event of a flat tire.Observe the "MOExtended tires (tires withrun-flat characteristics" section(Ypage 288).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory.It is therefore recommended that you addition-ally equip your vehicle with a TIREFIT kit if youmount tires that do not feature run-flat proper-ties, e.g. winter tires. A TIREFIT kit may beobtained from a qualified specialist workshop.
Emergency spare wheel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type
of the spare wheel or emergency spare
wheel and the wheel to be replaced may dif-
fer. Mounting an emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of an accident.
To avoid hazardous situations:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel
or emergency spare wheel that differs in
size.
Ronly use a spare wheel or emergency
spare wheel of a different size briefly.
Rdo not switch ESP®off.
Rhave a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimen-
sions as well as the tire type must be cor-
rect.
When using an emergency spare wheel orspare wheel of a different size, you must not

exceed the vehicle's maximum design speedof 50 mph (80 km/h).
You should regularly check the pressure of theemergency spare wheel, particularly prior tolong trips, and correct the pressure as neces-sary (Ypage 307). The value on the wheel isvalid.
Snow chains must not be mounted on emer-gency spare wheels.
General notes
You can ask for information regarding permit-ted emergency spare wheels at an authorizedMercedes-Benz Center.
An emergency spare wheel may also be moun-ted against the direction of rotation. Observethe time restriction on use as well as thespeed limitation specified on the emergencyspare wheel.
Replace the tires after six years at the latest,regardless of wear. This also applies to theemergency spare wheel.
Tire pressure loss warning system (Can-ada only):as long as you are driving with theemergency spare wheel mounted, the tirepressure loss warning system cannot functionreliably. Only restart the tire pressure losswarning system when the defective wheel hasbeen replaced with a new wheel.
Vehicles with tire pressure monitor (USAonly):after an emergency spare wheel hasbeen mounted, the system may still displaythe tire pressure of the removed wheel for afew minutes. The value displayed for themounted emergency spare wheel is not thesame as the current tire pressure of the emer-gency spare wheel.

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).

Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the
brake fluid is too low, vapor pockets may
form in the brake system when the brakes
are applied hard. This would impair braking
efficiency. There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
When handling brake fluid, observe the impor-tant safety notes on service products(Ypage 334).
The brake fluid change intervals can be foundin the Maintenance Booklet.
Only use brake fluid approved by Mercedes-Benz in accordance with MB-Freigabe or MB-Approval 331.0.

iHave the brake fluid regularly replaced at aqualified specialist workshop and thereplacement confirmed in the MaintenanceBooklet.
Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreeze is not
spilled next to the filler neck. Thoroughly
clean the antifreeze from components
before starting the engine.

Comply with the important safety notes forservice products when handling coolant(Ypage 334).
The coolant is a mixture of water and corro-sion inhibitor/antifreeze concentrate. It per-forms the following tasks:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection downto -35 ‡ (-37 †), the boiling point of the cool-ant during operation is approximately 266 ‡(130 †).
Theantifreeze concentrate/corrosion inhibitorconcentration in the engine cooling systemshould:
Rbe at least 50%. This will protect the enginecooling system against freezing down toapproximately -35 ‡(-37 †)
Rnot exceed 55% (antifreeze protection downto -49 ‡ [-45 †]). Otherwise, heat will notbe dissipated as effectively
Mercedes-Benz recommends a coolant or cor-rosion inhibitor/antifreeze concentrate inaccordance withMB Specifications for Service Products 310.1.
iWhen the vehicle is first delivered, it is fil-led with a coolant mixture that ensures ade-quate antifreeze and anti-corrosion protec-tion.
iThe coolant is checked with every mainte-nance interval at a qualified specialist work-shop.
