2019 MERCEDES-BENZ GLA tires

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.
General notes
HEnvironmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Read this section carefully before driving yourvehicle off-road.
Off-road driving is only possible with theON&OFFROAD package.
The following driving systems are speciallyadapted for driving over easily negotiable off-road terrain:
ROff-road program (Ypage 170)
ROff-road ABS (Ypage 60)
ROff-road 4ETS (Ypage 64)
ROff-road ESP®(Ypage 66)
RDSR (Downhill Speed Regulation)(Ypage 169)
Observe the following notes:
RStop the vehicle before starting to drivealong an off-road route. If necessary, acti-vate the off-road program (Ypage 132).
RTo avoid damaging the vehicle, make surethere is always sufficient ground clearance.
RCheck that items of luggage and loads arestowed safely and are well secured(Ypage 255).
RAlways keep the engine running and in gearwhen driving on a downhill gradient. Acti-vate DSR (Ypage 169).
154Driving tips
Driving and parking

RDrive slowly and evenly, if necessary at awalking pace.
REnsure that the wheels are in contact withthe ground at all times.
RDrive with extreme care on unfamiliar off-road routes where visibility is poor. Forsafety reasons, get out of the vehicle firstand survey the off-road route.
RCheck the depth of water before fording riv-ers and streams.
RWatch out for obstacles.
RTake care when turning on an uphill ordownhill slope or when driving across aslope. The vehicle could otherwise tip over.
RAlways keep the side windows and the pan-orama roof with power tilt/sliding panelclosed during the journey.
RDo not deviate from marked routes.
RDo not use the HOLD function when drivingoff-road, on steep uphill or downhill gradi-ents or on slippery or loose surfaces. TheHOLD function cannot hold the vehicle onsuch surfaces.
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
Raxle joints
XIf you detect strong vibrations after off-roadtravel, check for foreign objects in thewheels and drive train and remove them ifnecessary. Foreign objects can disturb thebalance and cause vibrations.
Driving over poor road surfaces places greaterdemands on your vehicle than driving on nor-mal roads. After driving off-road, check thevehicle. This allows you to detect damagepromptly and reduce the risk of an accident toyourself and other road users.
Driving on sand
Observe the following rules when driving onsand:
RActivate the off-road program (Ypage 132).
RAvoid high engine speeds.

AMG adaptive sport suspension sys-
tem
General notes
The electronically controlled damping systemworks continuously. This improves drivingsafety and ride comfort.
The damping is tuned individually to eachwheel and depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection ofSportorCom-fort
The suspension setting is adjusted using thecorresponding button in the center console.
iThe mode can also be set using the AMGDYNAMIC SELECT controller (Ypage 133).
Each time you start the engine with the Smart-Key or the Start/Stop button,Comfortmodeis activated. For further information aboutstarting the engine, see (Ypage 125).
Sport mode
The firmer setting of the suspension tuning inSportmode ensures even better contact withthe road. Select this mode when employing asporty driving style, e.g. on winding countryroads.

4MATIC
!Never tow the vehicle with one axle raised.This may damage the differential. Damageof this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels mustremain either on the ground or be fullyraised. Observe the instructions for towingthe vehicle with all wheels in full contactwith the ground.
4MATIC, together with ESP®, improves thetraction of your vehicle whenever a drivewheel spins due to insufficient grip.
If you fail to adapt your driving style, 4MATICcan neither reduce the risk of accident noroverride the laws of physics. 4MATIC cannottake account of road, weather and traffic con-ditions. 4MATIC is only an aid. You are respon-sible for the distance to the vehicle in front, forvehicle speed, for braking in good time and forstaying in your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far asnecessary when pulling away.
RAccelerate less when driving.
iIn wintry driving conditions, the maximumeffect of 4MATIC can only be achieved if youuse winter tires (M+S tires), with snowchains if necessary.
