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.

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.

explosion by improper handling of fuel.
You must avoid fire, open flames, smoking
and creating sparks. Switch off the ignition
before refueling and, if present, switch off
the auxiliary heating.
142Refueling
Driving and parking

RDrive slowly and evenly, if necessary at awalking pace.
REnsure that the wheels are in contact withthe ground at all times.
RDrive with extreme care on unfamiliar off-road routes where visibility is poor. Forsafety reasons, get out of the vehicle firstand survey the off-road route.
RCheck the depth of water before fording riv-ers and streams.
RWatch out for obstacles.
RTake care when turning on an uphill ordownhill slope or when driving across aslope. The vehicle could otherwise tip over.
RAlways keep the side windows and the pan-orama roof with power tilt/sliding panelclosed during the journey.
RDo not deviate from marked routes.
RDo not use the HOLD function when drivingoff-road, on steep uphill or downhill gradi-ents or on slippery or loose surfaces. TheHOLD function cannot hold the vehicle onsuch surfaces.
Checklist before driving off-road
XEngine oil level:check the engine oil leveland add oil if necessary.
When driving on steep gradients, the engineoil level must be sufficiently high to ensure acorrect oil supply in the vehicle.
XWheels and tires:check the tire treaddepth and tire pressure.
XCheck for damage and remove any foreignobjects, e.g. small stones, from the wheels/tires.
XReplace any missing valve caps.
XReplace dented or damaged wheels.
XRims:dented or bent rims can result in aloss of tire pressure and damage the tirebead. Before driving off-road, check thewheels and replace them if necessary.
Checklist after driving off-road
!If you detect damage to the vehicle afterdriving off-road, have the vehicle checkedimmediately at a qualified specialist work-shop.
XDeactivate off-road program (Ypage 132).
XDeactivate DSR (Ypage 169).
XClean the headlamps and rear lights andcheck for damage.
XClean the front and rear license plates.
XClean the wheels and tires with a water jetand remove any foreign objects.
XClean the wheels, wheel housings and thevehicle underside with a water jet; check forany foreign objects and damage.
XCheck whether twigs or other parts of plantshave become trapped. These increase therisk of fire and can damage fuel pipes, brakehoses or the air bellows of the axle jointsand propeller shafts.
XAfter the trip, examine without fail the entireundercarriage, wheels, tires, brakes, body-work structure, steering, chassis andexhaust system for damage.
XAfter driving in sand, mud, gravel, water orsimilar dirty conditions, have the followingchecked and cleaned:
Rbrake discs
Rwheels
Rbrake pads
Raxle joints
XIf you detect strong vibrations after off-roadtravel, check for foreign objects in thewheels and drive train and remove them ifnecessary. Foreign objects can disturb thebalance and cause vibrations.
Driving over poor road surfaces places greaterdemands on your vehicle than driving on nor-mal roads. After driving off-road, check thevehicle. This allows you to detect damagepromptly and reduce the risk of an accident toyourself and other road users.
Driving on sand
Observe the following rules when driving onsand:
RActivate the off-road program (Ypage 132).
RAvoid high engine speeds.
RUse the left-hand steering wheel paddleshifter to shift to a lower gear appropriate tothe terrain.

Checking and adding other service
products
Checking coolant level
GWARNING
The cooling system is pressurized, particu-
larly when the motor is warm. If you open
the cap, you could be scalded if hot coolant
sprays out. There is a risk of injury.
Let the engine cool down before you open
the cap. Wear protective gloves and protec-
tive eyewear when opening. Open the cap
slowly to release pressure.
!The coolant level must only be checkedand corrected when the engine has cooleddown (coolant temperature under 104 ‡(40 †). Checking the coolant level when thecoolant temperature is over 104 ‡ (40 †)can lead to damage to the engine or theengine cooling system.
XPark the vehicle on a level surface.
Only check the coolant level when the vehi-cle is on a level surface and the engine hascooled down.
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 125).
XCheck the coolant temperature display inthe instrument cluster.The coolant temperature must be below104 ‡ (40 †).
XTurn the SmartKey to positionZ(Ypage 125) in the ignition lock .
XSlowly turn capCcounter-clockwise and torelieve excess pressure.
XTurn capCfurther counter-clockwise andremove it.If the coolant is at the level of marker bar

XClean sensorsCof the driving systemswith water, car shampoo and a soft cloth.
Cleaning the rear view camera
!Do not clean the camera lens and the areaaround the rear view camera with a powerwasher.
XMake sure that the vehicle is at a standstilland the SmartKey is in positionHin theignition lock.
XOpen the camera cover for cleaning via themultimedia system (see Digital Operator'sManual).
XTo clean the rear view camera:use clearwater and a soft cloth to clean cameralensC.
Cleaning the exhaust pipes
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could
burn yourself. There is a risk of burns.
Always be particularly careful and supervise
children closely around the exhaust pipe and
the exhaust pipe trims. Allow these compo-
nents to cool down before touching them.
!Do not clean the exhaust pipe with acid-based cleaning agents, such as bathroomcleaner or wheel cleaner.
!Mercedes‑AMG vehicles with black tail-pipes: black chrome trims must not be pol-ished with a chrome polish as this will causethem to lose their black shine. For optimalcare, the faceplates should be rubbed with alightly oiled cloth after every car wash. Com-mercially available engine oils and care oilsare suitable for use.
For heavier soiling, you can apply a finepaintwork polish with a microfiber cloth.Remove the excess polish residue after pol-ishing.
Impurities combined with the effects of roadgrit and corrosive environmental factors maycause flash rust to form on the surface. Youcan restore the original shine of the exhaustpipe by cleaning it regularly, especially in win-ter and after washing.
XClean the exhaust pipe with a care producttested and approved by Mercedes-Benz.
Interior care
Cleaning the display
!For cleaning, do not use any of the follow-ing:
Ralcohol-based thinner or gasoline
Rabrasive cleaning agents
Rcommercially-available household clean-ing agents

Recommended tire pressures
The recommended tire pressure applies to thetires mounted at the factory.
The Tire and Loading Information placard con-tains the recommended tire pressures for coldtires on a fully loaded vehicle and for the maxi-mum permissible vehicle speed.
The tire pressure table contains the recom-mended pressures for cold tires for variousoperating conditions, i.e. differing load andspeed conditions.
Increased vehicle weight due to optional
equipment
The combined weight of all standard andoptional equipment available for the vehicle,regardless of whether it is actually installed onthe vehicle or not.
Rim
This is the part of the wheel on which the tireis mounted.
GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weightrating. The actual load on an axle must neverexceed the gross axle weight rating. The grossaxle weight rating can be found on the vehicleidentification plate on the B-pillar on the driv-er's side.
Speed rating
The speed rating is part of the tire identifica-tion. It specifies the speed range for which thetire is approved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weightof the vehicle including fuel, tools, the sparewheel, accessories installed, occupants, lug-gage and the drawbar noseweight, if applica-ble. The gross vehicle weight must not exceedthe gross vehicle weight rating GVWR as speci-fied on the vehicle identification plate on theB-pillar on the driver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible grossweight of a fully loaded vehicle (the weight ofthe vehicle including all accessories, occu-pants, fuel, luggage and the drawbar nose-weight, if applicable). The gross vehicle weightrating is specified on the vehicle identificationplate on the B-pillar on the driver's side.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optionalequipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-sponds to 1 psi. Another unit for tire pressureis bar. 100 kilopascals (kPa) are the equivalentof 1 bar.
Load index
In addition to the load-bearing index, the loadindex may also be imprinted on the sidewall ofthe tire. This specifies the load-bearing capa-city more precisely.
Curb weight
The weight of a vehicle with standard equip-ment including the maximum capacity of fuel,oil and coolant. It also includes the air-condi-tioning system and optional equipment if theseare installed in the vehicle, but does notinclude passengers or luggage.
Maximum load rating
The maximum tire load is the maximum per-missible weight in kilograms or lbs for which atire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for onetire.
Maximum load on one tire
Maximum load on one tire. This is calculatedby dividing the maximum axle load of one axleby two.
PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire widthin percent.
Tire pressure
This is pressure inside the tire applying an out-ward force to each square inch of the tire'ssurface. The tire pressure is specified in
324All about wheels and tires
Wheels and tires

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.
Mounting a wheel
Preparing the vehicle
XStop the vehicle on solid, non-slippery andlevel ground.
