ProblemPossible causes/consequences andPPSolutions
The engine is not run-ning smoothly and ismisfiring.
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 con-verter and damage it.
XHave the cause rectified immediately at a qualified specialistworkshop.
The coolant tempera-ture gauge shows avalue above 248 ‡(120 †). The warninglamp may also be onand a warning tone maysound.
The coolant level is too low. The coolant is too hot and the engine isno longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant tocool down.
XCheck the coolant level (Ypage 276). Observe the warning notesas you do so and add coolant if necessary.
Notes on towing vehicles
The vehicle is not suitable for attaching towbar systems, such as those used for flat tow-ing or dinghy towing.
Attaching or using tow bar systems may resultin damage 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 vehi-cle.
The vehicle/trailer combination may swerve.
Observe the permissible towing methods(Ypage 300) and the notes on towing withboth axles on the ground (Ypage 300).

Transmission positions
EPark position
This prevents the vehicle from roll-ing away when stopped.
Only shift the transmission to posi-tion]when the vehicle is station-ary. The parking lock should not beused as a brake when parking.Always apply the electronic parkingbrake in addition to the parking lockin order to secure the vehicle.
In the event of a malfunction of thevehicle's electronics, the transmis-sion may lock in position]. Havethe vehicle electronics checkedimmediately at a qualified specialistworkshop.
Park position]is automaticallyengaged if:
Ryou switch off the engine usingthe SmartKey and remove theSmartKey
Ryou switch off the engine usingthe SmartKey or using the Start/Stop button and open the driver'sdoor or front-passenger door
Ryou open the driver's door whenthe vehicle is stationary or whendriving at a very low speed andthe transmission is in position[or^
FReverse gear
Only shift the transmission intoposition^when the vehicle is sta-tionary.
DNeutral
Do not shift the transmission to\\while driving. The automatic trans-mission could otherwise be dam-aged.
No power is transmitted from theengine to the drive wheels.
Releasing the brakes will allow youto move the vehicle freely, e.g. topush it or tow it.
If ESP®is deactivated or faulty: shiftthe transmission to position\\ifthe vehicle is in danger of skidding,e.g. on icy roads.
If you switch the engine off with thetransmission in position^or[,the automatic transmission shifts to\\automatically.
!Coasting in neutral\\maycause damage to the drive train.
:Drive
The automatic transmissionchanges gear automatically. Allforward gears are available.
Driving tips
Changing gear
The automatic transmission shifts through theindividual gears automatically when it is intransmission position[. This automatic gearshifting behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts

Manual gearshifting
General notes
You can change gear yourself using the steer-ing wheel paddle shifters. The transmissionmust be in 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 leverto position[.
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. inthe case of lateral acceleration, during anoverrun phase or when driving on steep ter-rain.
XTo deactivate:pull steering wheel paddleshifterDand hold it in place.
or
XUse the DIRECT SELECT lever to switch thetransmission position.

Rstart the engine
There is a risk of an accident and injury.
Never leave children or animals unattended
in the vehicle.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. This
also applies for the Digital Vehicle Key if the
"Digital Vehicle Key" function is activated via
Mercedes me connect.
The function of the electric parking brake isdependent on the on-board voltage. If the on-board voltage is low or there is a malfunctionin the system, it may not be possible to applythe released parking brake.
XIf this is the case, only park the vehicle onlevel ground and secure it to prevent it roll-ing away.
XShift the automatic transmission to position].
It may not be possible to release an appliedparking brake if the on-board voltage is low orthere is a malfunction in the system. Contact aqualified specialist workshop.
The electric parking brake performs a functiontest at regular intervals while the engine isswitched off. The sounds that can be heardwhile this is occurring are normal.
Applying or releasing manually
XTo apply:push handleC.When the electric parking brake is applied,the redI(USA only) or$(Canadaonly) indicator lamp lights up in the instru-ment cluster.

Start-off Assist (except Mercedes-
AMG vehicles)
Important safety notes
GWARNING
If you use start-off assist, individual wheels
may start to spin and the vehicle may skid. If
ESP®is deactivated, there is a greater dan-
ger of skidding and having an accident.
Make sure that no persons or obstacles are
in the vicinity of the vehicle.
Start-off assist enables optimum accelerationfrom a standstill. For this, a suitably high-griproad surface is required and the vehicle andtires must be in good working order.
Do not activate start-off assist on public roads.
Observe the safety notes on driving safety sys-tems (Ypage 60).
Be sure to read the safety notes and informa-
tion on ESP®(Ypage 63).
Activating start-off assist
XDeactivate ESP®(Ypage 197).
XTurn the steering wheel to the straight-ahead position.
XFirmly depress the brake pedal with your leftfoot and keep it depressed.
XShift the transmission to position[.
XUse the DYNAMIC SELECT button to selecttheSdrive program (Ypage 132).
XQuickly depress the accelerator pedal fully.
XTake your foot off the brake, but keep theaccelerator pedal depressed.The vehicle pulls away at maximum acceler-ation.
iActivate ESP®as soon as the acceleration
process has ended. ESP®will otherwise notbe able to stabilize the vehicle if the vehiclestarts to skid or a wheel starts to spin.

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.
