HOLD function
General notes
The HOLD function can assist the driver in thefollowing situations:
RWhen pulling away, especially on steepslopes
RWhen maneuvering on steep slopes
RWhen waiting in traffic
The vehicle is kept stationary without thedriver having to depress the brake pedal.
The braking effect is canceled and the HOLDfunction deactivated when you depress theaccelerator pedal to pull away.
Important safety notes
GWARNING
If the vehicle is only braked using the HOLD
function, the vehicle may roll away in the fol-
lowing situations when you leave the vehi-
cle:
Rif there is a malfunction in the system or
in the voltage supply
Rif the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant
There is a risk of an accident.
Always deactivate the HOLD function and
secure the vehicle against rolling away
before you leave it.
!When Active Distance Assist DISTRONICor the HOLD function is activated, the vehi-cle brakes automatically in certain situa-tions.
To avoid damage to the vehicle, deactivateActive Distance Assist DISTRONIC and theHOLD function in the following or similar sit-uations:
Rwhen towing the vehicle
Rin the car wash
Deactivating the HOLD function (Ypage 165).

RACE START
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 forMercedes‑AMG vehicles.
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.
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.
iObserve the safety notes on driving safetysystems (Ypage 60).
Be sure to read the safety notes and infor-
mation on ESP®(Ypage 65).
Activation conditions
You can activate RACE START if:
Rthe doors are closed.
Rthe engine is running and it has reached anoperating temperature of approximately160 ‡ (71 †). This is the case when the oiltemperature gage in the multifunction dis-play is shown in white.

Adaptive damping system
General notes
A suspension with the adaptive damping sys-tem provides improved driving comfort andcontinuously controls the calibration of thedampers. The damping characteristics adaptto the current operating and driving situation.
The damping is tuned individually to eachwheel and depends on:
Ryour driving style, e.g. sporty
Rthe road surface conditions
Rthe selected drive program (Ypage 132).

General notes
The vehicle level can be set using theDYNAMIC SELECT controller (Ypage 133) orthe on-board computer (Ypage 171). The set-ting always corresponds to the last selectedfunction.
In order to reduce fuel consumption andimprove the driving dynamics, the vehicle islowered as its speed increases. In theSportandSport Plusdrive programs it is lowered byup to 0.5 in (13 mm), and in theComfortdriveprogram by up to 0.2 in (5 mm) compared tothe normal vehicle level. As the speed isreduced, the vehicle is raised up to the setvehicle height.
Each time you start the engine with the Smart-Key or the Start/Stop button, theComfortdrive program is activated. For further informa-tion about starting the engine, see(Ypage 127).
Select the normal level for normal road surfa-ces and the raised level for driving with snowchains or on particularly poor road surfaces.

Parking tips:
RThe way your vehicle is positioned in theparking space after parking is dependent onvarious factors. These include the positionand shape of the vehicles parked in frontand behind it and the conditions of the loca-tion. It may be the case that Active ParkingAssist guides you too far into a parkingspace, or not far enough into it. In somecases, it may also lead you across or onto
the curb. If necessary, cancel the parkingprocedure with Active Parking Assist.
RYou can also preselect transmission position[. The vehicle redirects and does not driveas far into the parking space. Should thetransmission change take place too early,the parking procedure is canceled. A sensi-ble parking position can no longer be ach-ieved from this position.
Exiting a parking space
In order that Active Parking Assist can supportyou when exiting the parking space:
Rthe border of the parking space must behigh enough at the front and the rear. Acurb is too small, for example.
Rthe border of the parking space must not betoo wide. Your vehicle can be maneuveredinto a position at a maximum of 45° to thestarting position in the parking space.
Ra maneuvering distance of at least 3.3 ft(1.0 m) must be available.
Active Parking Assist can only assist you withexiting a parking space if you have parked thevehicle parallel to the direction of travel usingActive Parking Assist.
