display MERCEDES-BENZ GLA 2019 Service Manual

Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle covers adistance of 44 ft (approximately 14 m) persecond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to therecommended tire pressure.
RRemove unnecessary loads.
RRemove roof racks when they are not nee-ded.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RHave all maintenance work carried out asindicated by the service intervals in theMaintenance Booklet or by the service inter-val display.
Fuel consumption also increases when drivingin cold weather, in stop-start traffic and in hillyterrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident is greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.
These systems only work at peak efficiency ifthey are serviced exactly in accordance withthe manufacturer's specifications. Always havework on the engine carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose. In particular,work relevant to safety or on safety-relatedsystems must be carried out at a qualified spe-cialist workshop.
The engine settings must not be changedunder any circumstances. Furthermore, allspecific service work must be carried out atregular intervals and in accordance with theMercedes-Benz service requirements. Detailscan be found in the Maintenance Booklet.
ECO display
The ECO display shows you how economicalyour driving style is. The ECO display assistsyou in achieving the most economical drivingstyle for the selected settings and prevailingconditions. Your driving style can significantlyinfluence the vehicle's consumption.
CAcceleration
DCoasting

The ECO display consists of three sections,with an inner and outer area. The sections cor-respond to the following three categories:
CAcceleration(evaluation of theacceleration processes):
Rthe outer area fills up and theinner area lights up green: moder-ate acceleration, especially athigher speeds
Rthe outer area empties and theinner area is gray: sporty acceler-ation
DCoasting(evaluation of all deceler-ation processes):
Rthe outer area fills up and theinner area lights up green: antici-patory driving, keeping your dis-tance and early release of theaccelerator. The vehicle cancoast without use of the brakes.
Rthe outer area empties and theinner area is gray: frequent heavybraking

take advantage of engine braking. For thisyou must first activate manual gearshifting.This helps you to avoid overheating thebrakes and wearing them out excessively.
When you take advantage of engine braking,it is possible that a drive wheel will notrotate for some time, e.g. on a slippery roadsurface. This could cause damage to thedrive train. This type of damage is not cov-ered by the Mercedes-Benz warranty.
Briefly depressing the accelerator pedal ondownhill gradients while the manual drive pro-gramMis temporarily activated: the automatictransmission may switch to the last activeautomatic drive programEorS. The automatictransmission may shift to a higher gear. Thiscan reduce the engine's braking effect.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal
while driving, the braking system can over-
heat. This increases the stopping distance
and can even cause the braking system to
fail. There is a risk of an accident.
Never use the brake pedal as a footrest.
Never depress the brake pedal and the
accelerator pedal at the same time.
!Depressing the brake pedal constantlyresults in excessive and premature wear tothe brake pads.
If the brakes have been subjected to a heavyload, do not stop the vehicle immediately.Drive on for a short while. This allows the air-flow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rainwithout braking, there may be a delayed reac-tion from the brakes when braking for the firsttime. This may also occur after the vehicle hasbeen washed or driven through deep water.
You have to depress the brake pedal morefirmly. Maintain a greater distance from thevehicle in front.
After driving on a wet road or having the vehi-cle washed, brake firmly while paying attentionto the traffic conditions. This will warm up the
brake discs, thereby drying them more quicklyand protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-due may form on the brake discs and brakepads. This can result in a significantly longerbraking distance.
RIn order to prevent any salt build-up, applythe brakes occasionally while paying atten-tion to the traffic conditions.
RCarefully depress the brake pedal and thebeginning and end of a journey.
RMaintain a greater distance to the vehicleahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up inthe instrument cluster and
Ryou hear a warning tone while the engineis running
Observe additional warning messages in themultifunction display.
The brake fluid level may be too low due tobrake pad wear or leaking brake lines.
Have the brake system checked immedi-ately. Consult a qualified specialist work-shop to arrange this.
!A function or performance test should onlybe carried out on a 2-axle dynamometer. Ifyou wish to operate the vehicle on such adynamometer, please consult a qualifiedspecialist workshop in advance. You couldotherwise damage the drive train or thebrake system.
!As the ESP®system operates automati-cally, the engine and the ignition must beswitched off (the SmartKey must be in posi-tion

Selecting the drive program
Active Distance Assist DISTRONIC supports asporty driving style when you select theS+drive program (Ypage 138) or the manualdrive program (Ypage 140). Accelerationbehind the vehicle in front or to the set speedis then noticeably more dynamic. If you haveselected theE(Mercedes-AMG vehicles:C)drive program, the vehicle accelerates moregently. This setting is recommended in stop-and-start traffic.
Changing lanes
If you want to change to the overtaking laneon multi-lane roads, Active Distance AssistDISTRONIC supports you if:
Ryou are driving faster than 45 mph(70 km/h)
RActive Distance Assist DISTRONIC is main-taining the distance to a vehicle in front
Ryou switch on the appropriate turn signal
RActive Distance Assist DISTRONIC does notcurrently detect a danger of collision
If these conditions are fulfilled, your vehicle isaccelerated. Acceleration will be interrupted ifchanging lanes takes too long or if the dis-tance between your vehicle and the vehicle infront becomes too small.
Stopping
If Active Distance Assist DISTRONIC detectsthat the vehicle in front is stopping, it brakesyour vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-tionary and you do not need to depress thebrake.
iAfter a time, the electric parking brakesecures the vehicle and relieves the servicebrake.
iDepending on the specified minimum dis-tance, your vehicle will come to a standstillat a sufficient distance behind the vehicle infront. The specified minimum distance is setusing the control on the cruise control lever.
When Active Distance Assist DISTRONIC isactivated, the transmission is shifted automati-cally to position]if:
Rthe driver's seat belt is not fastened and thedriver's door is open.
Rthe engine is switched off, unless it is auto-matically switched off by the ECO start/stop function.
The electric parking brake is applied automati-cally if Active Distance Assist DISTRONIC isactive when the vehicle is stationary and:
Ra system malfunction occurs.
Rthe power supply is insufficient.
If a malfunction occurs, the transmission mayalso shift to position]automatically.
Setting a speed
Keep in mind that it may take a brief momentuntil the vehicle has accelerated or braked tothe speed set.
XPress the cruise control lever upCfor ahigher speed or downDfor a lower speed.
XTo adjust the set speed in 1 mph incre-ments (1 km/h increments):briefly pushthe cruise control lever upCor downDtothe pressure point.The last stored speed increases or decrea-ses in 1 mph (1 km/h) increments.
XTo adjust the set speed in 5 mph incre-ments (10 km/h increments):briefly pushthe cruise control lever upCor downDbeyond the pressure point.The last stored speed increases or decrea-ses in 5 mph (10 km/h) increments.
iActive Distance Assist DISTRONIC is notdeactivated if you depress the acceleratorpedal. If you accelerate to overtake, ActiveDistance Assist DISTRONIC adjusts the vehi-cle's speed to the last speed stored, afteryou have finished overtaking.
Setting a specified minimum distance
You can set the specified minimum distancefor Active Distance Assist DISTRONIC by vary-ing the time span between one and two sec-onds. This determines the distance that ActiveDistance Assist DISTRONIC is to maintain fromthe vehicle in front, depending on the roadspeed. You can see this distance in the multi-function display (Ypage 164).

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).

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.

DSR
General notes
iDSR (Downhill Speed Regulation) is onlyavailable for vehicles with the ON&OFF-ROAD package.
DSR is an aid to assist you when driving down-hill. It keeps the speed of travel at the speedselected on the on-board computer. Thesteeper the downhill gradient, the greater theDSR braking effect on the vehicle. When driv-ing on flat stretches of road or on an uphillgradient, the DSR braking effect is minimal ornonexistent.
DSR controls the vehicle’s speed when it isactivated and the transmission is in position[,^or\\. You can drive at a higher or alower speed than that set on the on-boardcomputer at any time by accelerating or brak-ing.
Important safety notes
GWARNING
If the speed driven and the set speed devi-
ate and you activate DSR on a slippery road
surface, the wheels may lose traction. There
is an increased danger of skidding and acci-
dents.
Before switching DSR on, please take into
consideration the road surface and the dif-
ference between driving speed and the set
speed.
If you fail to adapt your driving style, DSR canneither reduce the risk of accident nor over-ride the laws of physics. DSR cannot takeaccount of road, weather and traffic condi-tions. DSR is only an aid. You are responsiblefor the distance to the vehicle in front, forvehicle speed, for braking in good time and forstaying in your lane.
You are always responsible for keeping controlof the vehicle and for assessing whether thedownhill gradient can be managed. DSR maynot always be able to keep to the set speed,depending on road surface and tire conditions.Select a set speed suitable for the prevailingconditions and when necessary, apply thebrakes manually.
Further information about "Driving off-road"(Ypage 153).
Activating/deactivating DSR
If you activate DSR and no speed has beenset, the vehicle decelerates to 4 mph (Canada:6 km/h).
You can only activate DSR when driving atspeeds below 19 mph (Canada: 30 km/h).
Activating DSR
XPress buttonC.Indicator lampDlights up.
The status indicator in the multifunction dis-play shows, e.g.DSR 6 km/hDSR 6 km/h.
If the current vehicle speed is too high, theDSR symbol appears on the multifunction dis-play. You will also see the message:Max.Max.Speed 30 km/hSpeed 30 km/h.
