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).

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.

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.
If you enter or exit a parking space usingActive Parking Assist, and press buttonC,indicator lampDflashes. DSR can then notbe switched on.
Deactivating DSR
XPress buttonC.Indicator lampDgoes out.
The DSR symbol appears in the multifunc-tion display with theOffOffmessage.
DSR is deactivated automatically if you drivefaster than 22 mph (Canada: 35 km/h). TheDSR symbol appears in the multifunction dis-play along with theOffOffmessage. You alsohear a warning tone.

The wear patterns on the front and rear tiresdiffer, depending on the operating conditions.Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typicallywear more on the shoulders and the rear tiresin the center.
On vehicles that have the same size front andrear wheels, you can rotate the wheels accord-ing to the intervals in the tire manufacturer'swarranty book in your vehicle documents. If nowarranty book is available, the tires should berotated every 3,000 to 6,000 miles (5,000 to10,000 km). Depending on tire wear, this maybe required earlier. Do not change the direc-tion of wheel rotation.
Clean the contact surfaces of the wheel andthe brake disc thoroughly every time a wheelis rotated. Check the tire pressure and, if nec-essary, restart the tire pressure loss warningsystem (Canada only) or the tire pressuremonitor (USA only).
Direction of rotation
Tires with a specified direction of rotation haveadditional benefits, e.g. if there is a risk ofhydroplaning. These advantages can only begained if the tires are installed correspondingto the direction of rotation.
An arrow on the sidewall of the tire indicatesits correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,dry and preferably dark place. Protect the tiresfrom oil, grease, gasoline and diesel.
