GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact
with hot parts of the exhaust system. There
is a risk of fire.
When driving on an unpaved road or off-
road, check the vehicle underside regularly.
In particular, remove trapped plant parts or
other flammable material. Contact a quali-
fied specialist workshop immediately if dam-
age is detected.
!There is a risk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. on a highcurb or an unpaved road
Ryou drive too fast over an obstacle, e.g. acurb, a speed bump or a pothole in theroad
Ra heavy object strikes the underbody orparts of the chassis
In situations like this, the body, the under-body, chassis parts, wheels or tires could bedamaged without the damage being visible.Components damaged in this way can unex-pectedly fail or, in the case of an accident,no longer withstand the loads they aredesigned to.
If the underbody paneling is damaged, com-bustible materials such as leaves, grass ortwigs can gather between the underbodyand the underbody paneling. If these materi-als come in contact with hot parts of theexhaust system, they can catch fire.
In such situations, have the vehicle checkedand repaired immediately at a qualified spe-cialist workshop. If on continuing your jour-ney you notice that driving safety isimpaired, pull over and stop the vehicleimmediately, paying attention to road andtraffic conditions. In such cases, consult aqualified specialist workshop.
The vehicle is only designed for easily negotia-ble off-road terrain and poor road surfaces.
When driving off-road, substances such assand, mud and water or water mixed with oilmay get into the brakes. This could result in areduced braking effect or in total brake failureand also in increased wear and tear. The brak-ing characteristics change depending on thematerial entering the brakes. Clean the brakesafter driving off-road. If you detect a reduced
braking effect or grinding noises, have thebrake system checked in a qualified specialistworkshop as soon as possible. Adapt yourdriving style to the different braking character-istics.
Driving off-road increases the likelihood ofdamage to the vehicle, which, in turn, can leadto failure of the mechanical assembly or sys-tems. Adapt your driving style to suit the ter-rain conditions. Drive carefully. Have damageto the vehicle rectified immediately at a quali-fied specialist workshop.
Do not shift into transmission position\\when driving off-road. You could lose controlof the vehicle if you attempt to brake the vehi-cle using the service brake. If the gradient istoo steep for your vehicle, drive back down inreverse gear.

Checklist before driving off-road
XEngine oil level:check the engine oil leveland add oil if necessary.
When driving on steep gradients, the engineoil level must be sufficiently high to ensure acorrect oil supply in the vehicle.
XWheels and tires:check the tire treaddepth and tire pressure.
XCheck for damage and remove any foreignobjects, e.g. small stones, from the wheels/tires.
XReplace any missing valve caps.
XReplace dented or damaged wheels.
XRims:dented or bent rims can result in aloss of tire pressure and damage the tirebead. Before driving off-road, check thewheels and replace them if necessary.
Checklist after driving off-road
!If you detect damage to the vehicle afterdriving off-road, have the vehicle checkedimmediately at a qualified specialist work-shop.
XDeactivate off-road program (Ypage 132).
XDeactivate DSR (Ypage 169).
XClean the headlamps and rear lights andcheck for damage.
XClean the front and rear license plates.
XClean the wheels and tires with a water jetand remove any foreign objects.
XClean the wheels, wheel housings and thevehicle underside with a water jet; check forany foreign objects and damage.
XCheck whether twigs or other parts of plantshave become trapped. These increase therisk of fire and can damage fuel pipes, brakehoses or the air bellows of the axle jointsand propeller shafts.
XAfter the trip, examine without fail the entireundercarriage, wheels, tires, brakes, body-work structure, steering, chassis andexhaust system for damage.
XAfter driving in sand, mud, gravel, water orsimilar dirty conditions, have the followingchecked and cleaned:
Rbrake discs
Rwheels
Rbrake pads

Information about Service
Resetting the ASSYST PLUS service
interval display
!If the ASSYST PLUS service interval dis-play has been inadvertently reset, this set-ting can be corrected at a qualified special-ist workshop.
Have service work carried out as describedin the Maintenance Booklet. This may other-wise lead to increased wear and damage tothe major assemblies or the vehicle.
A qualified specialist workshop, e.g. an author-ized Mercedes-Benz Center, will reset theASSYST PLUS service interval display after theservice work has been carried out. You canalso obtain further information on mainte-nance work, for example.
Special service requirements
The specified maintenance interval takes onlythe normal operation of the vehicle intoaccount. Under arduous operating conditionsor increased load on the vehicle, maintenancework must be carried out more frequently, forexample:
Rregular city driving with frequent intermedi-ate stops
Rif the vehicle is primarily used to travel shortdistances
Ruse in mountainous terrain or on poor roadsurfaces
Rif the engine is often left idling for long peri-ods
Rin particularly dusty conditions, or if air-recirculation mode is frequently used
In these or similar operating conditions, havethe interior filter, engine air cleaner, engine oil
and oil filter, for example, changed more fre-quently. Under arduous operating conditions,the tires must be checked more often. Furtherinformation can be obtained at a qualified spe-cialist workshop, e.g. an authorized Mercedes-Benz Center.
Driving abroad
An extensive Mercedes-Benz Service networkis also available in other countries. You canobtain further information from any authorizedMercedes-Benz Center.
Care
General notes
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
!When cleaning your car, do not use:
Rdry, coarse or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces and films withhard objects, e.g. rings or ice scrapers. Oth-erwise, you may scratch or damage the sur-faces and films.
!Do not park your vehicle for a long periodof time directly after cleaning, particularlyafter cleaning the wheel rim with wheelcleaner. Wheel cleaner can lead to theincreased corrosion of the brake discs andpads. Therefore, drive for a few minutesafter cleaning. By heating up the brakes, thebrake discs and pads dry. The vehicle canthen be parked for a long period of time.
Regular care of your vehicle is a condition forretaining the quality in the long term.

Cleaning the exhaust pipes
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could
burn yourself. There is a risk of burns.
Always be particularly careful and supervise
children closely around the exhaust pipe and
the exhaust pipe trims. Allow these compo-
nents to cool down before touching them.
!Do not clean the exhaust pipe with acid-based cleaning agents, such as bathroomcleaner or wheel cleaner.
!Mercedes‑AMG vehicles with black tail-pipes: black chrome trims must not be pol-ished with a chrome polish as this will causethem to lose their black shine. For optimalcare, the faceplates should be rubbed with alightly oiled cloth after every car wash. Com-mercially available engine oils and care oilsare suitable for use.
For heavier soiling, you can apply a finepaintwork polish with a microfiber cloth.Remove the excess polish residue after pol-ishing.
Impurities combined with the effects of roadgrit and corrosive environmental factors maycause flash rust to form on the surface. Youcan restore the original shine of the exhaustpipe by cleaning it regularly, especially in win-ter and after washing.
XClean the exhaust pipe with a care producttested and approved by Mercedes-Benz.
Interior care
Cleaning the display
!For cleaning, do not use any of the follow-ing:
Ralcohol-based thinner or gasoline
Rabrasive cleaning agents
Rcommercially-available household clean-ing agents
These may damage the display surface. Donot put pressure on the display surface

The wear patterns on the front and rear tiresdiffer, depending on the operating conditions.Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typicallywear more on the shoulders and the rear tiresin the center.
On vehicles that have the same size front andrear wheels, you can rotate the wheels accord-ing to the intervals in the tire manufacturer'swarranty book in your vehicle documents. If nowarranty book is available, the tires should berotated every 3,000 to 6,000 miles (5,000 to10,000 km). Depending on tire wear, this maybe required earlier. Do not change the direc-tion of wheel rotation.
Clean the contact surfaces of the wheel andthe brake disc thoroughly every time a wheelis rotated. Check the tire pressure and, if nec-essary, restart the tire pressure loss warningsystem (Canada only) or the tire pressuremonitor (USA only).
Direction of rotation
Tires with a specified direction of rotation haveadditional benefits, e.g. if there is a risk ofhydroplaning. These advantages can only begained if the tires are installed correspondingto the direction of rotation.
An arrow on the sidewall of the tire indicatesits correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,dry and preferably dark place. Protect the tiresfrom oil, grease, gasoline and diesel.

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.
