R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts of
ammonia vapour may be released.
Ammonia vapours have apungent odour and are
particularlyi rritating to the skin, to mucous
membranes and to the eyes. You may experi-
ence aburning sensation in your eyes, nose and
throat. You may also experience coughing and
watery eyes.
Do not inhale any ammonia vapours that may be
released.O nly fill the AdBlue ®
tank in well-ven-
tilated areas. Do not swallow AdBlue
®
or let it come into con-
tact with skin, eyes or clothing. Keep AdBlue ®
awayf rom children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off your skin with
soap and water.
R if AdBlue ®
comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical attention immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of
water. Seek medical attention immediately.
R change immediately out of clothing that has
come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
,a nd do not dilute AdBlue ®
with
water. This may destroy the BlueTEC exhaust
gas aftertreatments ystem.
! In order to fill the AdBlue ®
tank, the vehicle
must be parked on alevel surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on alevel surface.
Fluctuations in capacity will thus be avoided.
Filling avehicle standing on an uneven sur-
face is not permitted. There is adanger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatmentc omponents.
! Surfaces which have come into contact with
AdBlue ®
while refilling should be rinsed
immediately with water, or remove AdBlue ®
with amoist cloth and cold water. If AdBlue ®
has already crystallised,u seasponge and
cold water to clean the area. AdBlue ®
residue
crystallises after acertain amount of time and
soils the affected surfaces.
! AdBlue ®
is not afuel additive and must not
be added to the fuel tank. If AdBlue ®
is added
to the fuel tank, this can lead to engine dam-
age.
Have the AdBlue ®

171Driving and parking Z

Only release the ball coupling if the pivoting
range is unobstructed. Alwaysm ake sure that
the ball coupling engages when folding in.
When reversing the vehicle towards the trailer,
make sure there is nobody between the trailer
and the vehicle.
Couple and uncouple the trailer carefully.Ify ou
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing atrailer, your vehicle's handling
characteristics will be different in comparison to when driving without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has alarger turning circle
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain asafe distance. Drive carefully.
When towing atrailer, always adjust your speed
to the current road and weather conditions. Do
not exceed the maximum permissibles peed for
your vehicle/trailer combination. Notes on towing
atrailer
General notes Trailer towing is not permissibleont
he following
models:
R Mercedes AMG C63
R Mercedes AMG C63S
When towing atrailer, set the tyre pressure on
the rear axle of the towing vehicle for the max-
imum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 356).
On vehicles without level control, the height of
the ball coupling will alter according to the load
placed on the vehicle. If necessary, use atrailer
with aheight-adjustable drawbar.
You will find fitting dimensions and loads under "Technical data" (Y page 378). Driving tips Observe the notes on ESP
®
trailer stabilisation
(Y page 74).
The maximum permissibles peed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissibler ear axle load is increased
when towing atrailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 378). If you utilise any of the
added maximum rear axle load when towing a
trailer, the vehicle/trailer combination may not
exceed amaximum speed of 100 km/h for rea-
sons concerning the operating permit. This also applies in countries in which the permissible
maximum speed for vehicle/trailer combina-
tions is above 100 km/h.
When towing atrailer, your vehicle's handling
characteristics will be different in comparison to
when driving without atrailer and it will con-
sume more fuel.
Change into alower gear in good time on long
and steep downhill gradients.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
This will use the braking effect of the engine, so
less braking will be required to maintain vehicle speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary.
R Maintain agreater distance to the vehicle in
front than when driving without atrailer.
R Avoid braking abruptly.Ifp ossible,brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The valuesg iven for gradient-climbing capa-
bilities from astandstill refer to sea level.

WARNING
If the required tyre pressure is not reached
after driving for ashort period, the tyre is too
badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damaged tyres and atyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
i In yourv
ehicle, you willf indasticker with
the Mercedes-Benz Service24h telephone
number, e.g. on the B-pillar on the driver's
side.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi) .See the tyre pres-
sure table on the fuel filler flap for values.
X To increase the tyre pressure: switch on
the tyre inflation compressor. X
To reduce the tyre pressure: depress pres-
sure release button :next to pressure
gauge ;.
X When the tyre pressure is correct, unscrew
the filler hose from the valve of the sealed
tyre.
X Screw the valve cap onto the tyre valve of the
sealed tyre. X
To remove the tyre sealant bottle from the
tyre inflation compressor, press together the
locking tabs on the yellow cap.
X Pullt he tyre sealant bottle out of the tyre
inflation compressor.
The filler hose stays on the tyre sealant bottle.
X Drive to the neares tqualified specialist work-
shop and have the tyre changed there.
X Have the tyre sealant bottle and the filler hose
replaced as soon as possible at aqualified
specialist workshop.
X Have the tyre sealant bottle replaced every
four years at aqualified specialist workshop. Battery (vehicle)

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of apos-
itive terminal and an earth point, in the engine compartment.
All vehiclese xcept vehiclesw ithalithium-ion battery: G
WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing. Do not breathe in any battery gases. Do not lean over the battery. Keep the batteries out of the reach of children. Immediately rinse off battery acid
thoroughly with plenty of clean water and seek medical attention at once. G
WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, naked flames, creating sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting. Do not lean over abattery. G
WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jump leads.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the dis-
charged battery has frozen.Int his case you may neither jump-start the vehicle nor charge the
battery. The service life of abattery that has been thawed may be reduced. The starting charac-
teristics may be impaired, especially at low temperatures. Have the thawed battery checked at a
qualified specialist workshop.

WARNING
If you fit unsuitabl eaccessories onto tyre
valves, the tyre valve smay be overloadeda nd
malfunction, which can caus etyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can alsor esult in tyre pressure loss. There is a
risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
yourv ehicleonto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly ,the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in atyre
blow-out. There is arisk of accident.
R Check the tyre for foreig nobjects.
R Check whethe rthe whee lislosing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact aqualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
The recommende dtyre pressures for various
operating conditions can be found in the tyre
pressure table on the fuel filler flap
(Y page1 67).
Operation with an emergency spare wheel:
information on operation with an emergency
spar ewhee lcan be found in the genera lnotes in
the "Emergency spar ewheel" section
(Y page3 67).
Operation with atrailer: the applicable value
for the rear axle is the maximu mtyre pressure
valu estated in the table insid ethe fuel filler flap.
Additionally, the tyre pressure table may also
state tyre pressures for different loadc ondi-
tions. These are defined in the table as different numbers of passengers and amounts of lug-
gage .The actua lnumber of seats may vary ;for
more information, please refer to the vehicle's
registration documents.
If tyre sizes are not specified ,the tyre pressures
stated on the tyre pressure table apply for all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the fol-
lowing tyre pressure information is only vali dfor
that tyre size.
Use asuitable pressure gauge to check the tyre
pressure. The outer appearance of atyre does
not permi tany reliablec onclusion about the tyre
pressure. On vehicles fitted with the electronic
tyre pressure monitor, the tyre pressure can be checked using the on-board computer.
If possible,o nly correct tyre pressures when the
tyres are cold.
The tyres are cold:
R if the vehicl ehas been parked with the tyres
out of direct sunlight for at least three hours
and
R if the vehicl ehas not been drive nfurther than
1.6 km
Depending on the ambient temperature, the
vehicl espee dand the loadont he tyres, the tyre
temperature and thus the tyre pressure changes
by approximatel y10k Pa (0.1 bar/1.5 psi) per
10 †. Take this into account when checking the
pressure of warm tyres. Only correct the tyre
pressure if it is too low for the current operating conditions.
Driving with tyre pressure that is too high or too
low can:
R shorten the service life of the tyres
R caus eincreased tyre damage
R have anegative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are minimu mvalues which offer you good ride com-
fort characteristics.
However, you can alsou se the values given for
higher loads. These are permissible and willn ot
adversely affect the running of the vehicle.
This does not apply to vehicles towing atrailer. Tyre pressure
