ProblemPossible causes/consequences andPPSolutions
The engine does notstart. You cannot hearthe starter motor.
The on-board voltage is too low because the battery is too weak ordischarged.
XJump-start the vehicle (Ypage 282).
If the engine does not start despite attempts to jump-start it:
XConsult a qualified specialist workshop.
The starter motor was exposed to a thermal load that was too high.
XAllow the starter motor to cool down for approximately two minutes.
XTry to start the engine again.
If the engine still does not start:
XConsult a qualified specialist workshop.
The engine is not runningsmoothly and is misfir-ing.
There is a malfunction in the engine electronics or in a mechanicalcomponent of the engine management system.
XOnly depress the accelerator pedal slightly.Otherwise, non-combusted fuel may get into the catalytic converterand damage it.
XHave the cause rectified immediately at a qualified specialist work-shop.
The coolant temperaturegauge shows a valueabove 248 ‡ (120 †).The coolant warninglamp may also be on anda warning tone maysound.
The coolant level is too low. The coolant is too hot and the engine is nolonger being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant tocool down.
XCheck the coolant level (Ypage 263). Observe the warning notesas you do so and add coolant if necessary.
Notes on towing vehicles
The vehicle is not suitable for attaching tow barsystems, such as those used for flat towing ordinghy towing.
Attaching or using tow bar systems may result indamage to the vehicle.
When towing a vehicle with tow bar systems,safe driving characteristics cannot be guaran-teed for the towing vehicle or the towed vehicle.
The vehicle/trailer combination may swerve.
Observe the permissible towing methods(Ypage 287) and the notes on towing with bothaxles on the ground (Ypage 286).
DYNAMIC SELECT button (all vehicles
except Mercedes-AMG vehicles)
Use the DYNAMIC SELECT button to change thedrive program. Depending on the drive programselected the following vehicle characteristicswill change:

Drive program I (Individual)
In drive programIthe following properties of thedrive program can be selected:
Rthe drive (engine and transmission manage-ment)
Rthe suspension (vehicles with damping sys-tem or AMG adaptive sport suspension sys-tem)
Rthe steering
Rthe availability of the ECO start/stop function
Rthe climate control
Information about configuring drive programIwith the multimedia system can be found in theDigital Operator's Manual.
iTo permanently select the gears in driveprogramIusing the steering wheel paddleshifters, select theM(manual) setting for thedrive.
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 in forwardand reverse gears, unless the acceleratorpedal is depressed fully.
Rthe vehicle has improved driving stability, forexample on slippery road surfaces.
Rthe automatic transmission shifting upsooner. This results in the vehicle being drivenat lower engine speeds and the wheels beingless likely to spin.
Rgliding mode is activated automatically whenengine-internal conditions are fulfilled andthe accelerator is not depressed. At the sametime the transmission’s clutch opens and thevehicle rolls freely using its kinetic energy. Asa result great distances can be completedwithout the engine brake and fuel consump-tion 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.

Manual gear shifting
General notes
You can change gear yourself using the steeringwheel paddle shifters. The transmission must bein position[to do this.
Depending on which steering wheel paddleshifter is pulled, the automatic transmissionimmediately shifts into the next gear down orup, if permitted.
Mercedes-AMG vehicles:to use manual shift-ing, you have two options:
Rtemporary setting
Rpermanent setting
If you activate manual gearshifting, the multi-function display will show the current gearinstead of transmission position[.
If manual gearshifting is deactivated, the gearswill be selected automatically.
Temporary setting
XTo activate:shift the DIRECT SELECT lever toposition[.
XPull steering wheel paddle shifterCorD.
Temporary setting will be active for a certainamount of time. Under certain conditions theminimum amount of time is extended, e.g. in thecase of lateral acceleration, during an overrunphase or when driving on steep terrain.
XTo deactivate:pull steering wheel paddleshifterDand hold it in place.

General notes
The electronically controlled damping systemworks continuously. This improves drivingsafety and ride comfort.
The damping is tuned individually to each wheeland depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection ofSportorComfort
The suspension setting is adjusted using thecorresponding button in the center console.
iThe mode can also be set using the AMGDYNAMIC SELECT controller (Ypage 130).
Each time you start the engine with the Smart-Key or the Start/Stop button,Comfortmode isactivated. For further information about startingthe engine, see (Ypage 123).
