2019 MERCEDES-BENZ GLA clutch

Holding the vehicle stationary on
uphill gradients
GWARNING
If the clutch overheats, the electronic man-
agement system is automatically deactiva-
ted. This interrupts the power transmission.
The vehicle may, for example, roll back-
wards on gradients. There is a risk of an
accident.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
The clutch may overheat if you hold the vehi-cle stationary on uphill gradients by depress-ing the accelerator pedal. If the clutch over-heats, a warning tone sounds.

Do not hold the vehicle stationary on uphillgradients by depressing the accelerator pedal.Instead, only ever hold the vehicle stationaryon uphill gradients by:
Rdepressing the brake pedal
Ractivating the HOLD function
Rengaging the electric parking brake
Kickdown
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond thepressure point.The automatic transmission shifts to a lowergear depending on the engine speed.
XEase off the accelerator pedal once thedesired speed is reached.The automatic transmission shifts back up.
Mercedes-AMG vehicles:it is only possibleto use kickdown in the automatic drive pro-gram and the temporary manual drive programM. When manual drive programMis perma-nently activated, kickdown is not possible.
For further information on kickdown in manualdrive programM(Ypage 142).
Rocking the vehicle free
Shifting back and forth between transmissionpositions[and^can help to free up thevehicle if it gets stuck in mud or snow. Thevehicle's engine management system limitsthe speed to a maximum of 5 mph (9 km/h)when shifting back and forth. To shift repeat-edly between transmission positions[and^, move the DIRECT SELECT lever up anddown past the point of resistance.
Drive programs
All vehicles (except Mercedes-AMG
vehicles)
Drive program C (Comfort)
Drive programCis characterized by the follow-ing:
Rthe vehicle delivers comfortable, economicalhandling characteristics.
Rthe vehicle pulls away more gently inforward and reverse gears, unless the accel-erator pedal is depressed fully.
Rthe vehicle has improved driving stability,for example on slippery road surfaces.
Roptimal fuel consumption resulting from theautomatic transmission shifting up sooner.The vehicle is driven in the low engine speedrange and the wheels are less likely to spin.
Drive program S (Sport)
Drive programSis characterized by the follow-ing:
Rsporty engine settings.
Rthe automatic transmission shifts up later.The fuel consumption possibly being higheras a result of the later automatic transmis-sion shift points.
Drive program I (Individual)
In drive programIthe following properties ofthe drive program can be selected:
Rthe drive (engine and transmission manage-ment)
Rthe steering
138Automatic transmission
Driving and parking

Rthe availability of the ECO start/stop func-tion
Rthe climate control
Information about configuring drive programIwith the multimedia system can be found inthe Digital Operator's Manual.
iTo permanently select the gears in driveprogramIusing the steering wheel paddleshifters, select theM(manual) setting forthe drive.
Offroad drive program
TheOff-roaddrive program is characterizedby the following:
Rthe vehicle exhibits optimal driving charac-teristics on easily negotiable off-road ter-rain.
Drive program E (Economy)
Drive programEis characterized by the follow-ing:
Rcomfort-oriented engine settings.
Roptimal fuel consumption resulting from theautomatic transmission shifting up sooner.
Rthe vehicle pulls away more gently inforward and reverse gears, unless the accel-erator pedal is depressed fully.
Rthe vehicle has improved driving stability,for example on slippery road surfaces.
Rthe automatic transmission shifting upsooner. This results in the vehicle beingdriven at lower engine speeds and thewheels being less likely to spin.
Rgliding mode is activated automaticallywhen engine-internal conditions are fulfilledand the accelerator is not depressed. At thesame time the transmission’s clutch opensand the vehicle rolls freely using its kineticenergy. As a result great distances can becompleted without the engine brake andfuel consumption reduced.
iThe availability of gliding mode depends onvarious factors, including the following:
Rthe engine and transmission temperature
Rthe downhill gradient
Rthe vehicle speed
Rperforming regular adaptation functions
When you depress the brake pedal, glidingmode is deactivated, depending on pedalpressure.
When you activate cruise control or ActiveDistance Assist DISTRONIC, gliding mode isnot available.

RACE START (Mercedes-AMG vehi-
cles)
Important safety notes
iRACE START must not be used on normalroads. RACE START must only be activatedand used on dedicated road circuits, outsideof public road use.
iRACE START is only available inMercedes‑AMG vehicles.
GWARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP®mode,
there is an increased risk of skidding and
having an accident. Make sure that no per-
sons, animals or obstacles are within range
of the vehicle.
RACE START enables optimal accelerationfrom a standing start. For this, a suitably high-grip road surface is required and the vehicleand tires must be in good working order.
iObserve the safety notes on driving safetysystems (Ypage 60).
Be sure to read the safety notes and infor-
mation on ESP®(Ypage 63).
Conditions for activation
You can activate RACE START if:
Rthe doors, hood and the trunk lid are closed.
Rthe engine is running and the transmission,all-wheel drive clutch and the engine are atoperating temperature.
Rthe steering wheel is in the straight-aheadposition.
Rthe vehicle is stationary and the brake pedalis depressed (left foot).
Rthe transmission is in position[.
