GWARNING
Fuels are toxic and harmful to health. There
is a risk of injury.
You must avoid fuels coming into contact
with skin, eyes and clothes or being swal-
lowed.
Do not inhale the fuel vapors. Keep children
away from fuels.
Keep doors and windows closed during the
refueling process.
If you or others come into contact with fuel,
observe the following points:
RImmediately rinse the fuel off your skin
with soap and water.
RIf you get fuel into your eyes, immediately
rinse your eyes throughly with clean
water. Seek medical attention immedi-
ately.
RSeek medical attention immediately if fuel
has been swallowed. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic charging can lead to the crea-
tion of sparks and ignite fuel vapor. There is
a risk of fire and explosion.
Touch the metallic body of the vehicle
before you open the fuel filler cap or handle
the pump nozzle. Any possible electrostatic
charge present will in this way be depleted.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with agasoline engine. Do not switch on the igni-tion if you accidentally refuel with the wrongfuel. Otherwise, the fuel will enter the fuelsystem. Even small amounts of the wrongfuel could result in damage to the fuel sys-tem and the engine. Notify a qualified spe-cialist workshop and have the fuel tank andfuel lines drained completely.
!Overfilling the fuel tank could damage thefuel system.
!Take care not to spill any fuel on paintedsurfaces. You could otherwise damage thepaintwork.
!Use a filter when adding fuel from a fuelcan. The fuel lines and/or the fuel injectionsystem could otherwise be blocked by parti-cles from the fuel can.
Do not get into the vehicle again during therefueling process. Otherwise, electrostaticcharge could build up again.
If you overfill the fuel tank, fuel could sprayout when the fuel pump nozzle is removed.

Loading guidelines
GWARNING
If objects, luggage or loads are not secured
or not secured sufficiently, they could slip,
tip over or be flung around and thereby hit
vehicle occupants. There is a risk of injury,
particularly in the event of sudden braking
or a sudden change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Exhaust gases can enter the vehicle interior
if the tailgate is open while the engine is
running, especially if the vehicle is in
motion. There is a risk of poisoning.
Always switch off the engine before opening
the tailgate. Never drive with the tailgate
open.
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.
The handling characteristics of a laden vehicleare dependent on the distribution of the loadwithin the vehicle.
Observe the following notes when loading andtransporting a load:
RNever exceed the maximum permissiblegross vehicle mass or the gross axle weightrating for the vehicle (including occupants).The values are specified on the vehicle iden-
tification plate on the B-pillar of the driver'sdoor.
RThe cargo compartment is the preferredplace to carry objects.
RPosition heavy loads as far forward as possi-ble and as low down in the cargo compart-ment as possible.
RThe load must not protrude above the upperedge of the seat backrests.
RAlways place the load against the rear orfront seat backrests. Make sure that theseat backrests are securely locked intoplace.
RAlways place the load behind unoccupiedseats if possible.
RUse the cargo tie-down rings and the parcelnets to transport loads and luggage.
RUse cargo tie-down rings and fasteningmaterials appropriate for the weight andsize of the load.
RThe maximum load capacity of the stowagewell under the cargo compartment floor is55 lbs(25 kg).
RSecure the load with sufficiently strong andwear-resistant tie-downs. Pad sharp edgesfor protection.
!Do not position the load on one part of thefolding cargo compartment floor only. Themaximum load capacity of the folding cargocompartment floor is 220 lbs(100 kg). Dis-tribute theweight evenly to avoid damagingthe cargo compartment floor. Place a solidboard under the load if necessary. Pleasenote that the load on the cargo compart-ment floor will be increased when the loadis lashed down.

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.

For safety reasons, Mercedes-Benz recom-mends that you only use batteries which havebeen tested and approved for your vehicle byMercedes-Benz. These batteries provideincreased impact protection to prevent vehicleoccupants from suffering acid burns shouldthe battery be damaged in the event of anaccident.
In order for the battery to achieve the maxi-mum possible service life, it must always besufficiently charged.
Like other batteries, the vehicle battery maydischarge over time if you do not use the vehi-cle. In this case, have the battery disconnec-ted at a qualified specialist workshop. You canalso charge the battery with a charger recom-mended by Mercedes-Benz. Contact a quali-fied specialist workshop for further informa-tion.
Have the battery condition of charge checkedmore frequently if you use the vehicle mainlyfor short trips or if you leave it standing idlefor a lengthy period. Consult a qualified spe-cialist workshop if you wish to leave your vehi-cle parked for a long period of time.
Only replace a battery with a battery that hasbeen recommended by Mercedes-Benz.
Remove the SmartKey if you park the vehicleand do not require any electrical consumers.The vehicle will then use very little energy,thus conserving battery power.
If the power supply has been interrupted, e.g.if you reconnect the battery, you will have to:
Rset the clock using the multimedia system(see the Digital Operator's Manual)
Rreset the function for folding the exteriormirrors in/out automatically, by folding themirrors out once (Ypage 99)
Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is
a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is suffi-
cient ventilation while charging and jump-
starting. Do not lean over a battery.
GWARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
GWARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery,
gases can escape from the battery. There is
a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with a maximumcharging voltage of 14.8 V.
!Only charge the battery using the jump-starting connection point.
