In case of a blinking indicator lamp
;,
pressure on the fuel tank system needs to be
released first.
A malfunction in the system has been
detected if
R the indicator lamp ; fails to stop blinking
after approximately 10 seconds after the
fuel filler flap switch : has been pressed
R the indicator lamp ; does not come on at
all
R the malfunction indicator lamp ! (USA
only) or ; (Canada only) comes on
The fuel filler flap is located on the right-hand
side of the vehicle towards the rear.
i In case the fuel filler flap switch does not
release the fuel filler flap, see “Opening the
fuel filler flap manually” ( Y page 31).G
Warning!
Remove fuel filler cap slowly. Fuel spray may
cause injury.
Complete refueling within 20 minutes after
opening the fuel filler flap. Otherwise fuel may
spray out and cause injury. If the refueling
process cannot be completed within
20 minutes, press the fuel filler flap switch
again.
i Leaving the combustion engine running
and the fuel filler cap open can cause the
yellow fuel tank reserve warning lamp to
flash and the malfunction indicator
lamp ! (USA only) or ; (Canada
only) to illuminate.
For more information on refueling, see
Operator's Manual. X
Opening: Pull fuel filler flap = out in
direction of arrow.
X Turn fuel filler cap ? counterclockwise.
X Take off fuel filler cap ?.
! The fuel filler cap is tethered to the fuel
filler neck. Do not drop the cap. It could
damage the vehicle paint finish.
X Set fuel filler cap ? on fuel filler flap =.
X Fully insert filler nozzle unit and refuel.
X Only fill your tank until the filler nozzle unit
cuts out – do not top off or overfill .
X Closing: Turn fuel filler cap ? until it
audibly engages.
X Close fuel filler flap =.
The fuel filler flap is locked.
The indicator lamp on the fuel filler flap
switch goes out ( Y page 20). Engine oil
The amount of oil your combustion engine
consumes will depend on a number of factors,
including driving style. Increased oil
consumption can occur when the vehicle is
new or the vehicle is driven frequently at
higher engine speeds.
Engine oil consumption checks should only
be made after the vehicle break-in period.
! Do not use any special lubricant additives,
as these may damage the drive assemblies. Operation

Notes
Your vehicle is equipped with a 12-volt
battery and a high-voltage battery. The high-
voltage battery stores the power required for
the hybrid transmission. The hybrid
transmission also starts the combustion
engine.
Have any work on the batteries performed at
an authorized Mercedes-Benz Center.
i Read and observe the safety notes
(Y page 8) and the notes on the 12-volt
battery in the Operator’s Manual. G
Warning!
The electrolyte, i.e. the battery fluid, is toxic
and caustic. Do not allow this fluid to come in
contact with eyes, skin or clothing, for
example in case of an accident.
In case it does, immediately flush affected
area with water and seek medical help
immediately.
For information on the location of the 12-volt
battery and the high-voltage battery, see
(Y page 12). !
Deep discharge caused by prolonged
periods of the vehicle not being used, can
damage the high-voltage battery.
During such periods, operate the vehicle
every 4 weeks for several minutes in order
to charge the high-voltage battery.
During the charging process, switch off
electrical consumers that are currently not
needed, e.g. climate control system or seat
heating.
If necessary, get a jump start. G
Warning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and lead to death. Do not
run the engine in confined areas (such as a
garage) which are not properly ventilated.
If you do not intend to operate your vehicle
for an extended period of time, contact an
authorized Mercedes-Benz Center about
steps you need to observe. Charging the battery
Charging the 12-volt battery G
Warning!
Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit approved by Mercedes-Benz is
being used. Gases may escape during
charging and could cause an explosion that
may result in personal injury, paint damage or
corrosion.
An accessory battery charge unit specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for
information and availability. 32

Warning!
Comply with all valid regulations with respect
to handling, storing, and disposing of service fluids. Otherwise you could endanger persons
or the environment.
Keep service fluids out of the reach of
children.
For health reasons, you should prevent
service
fluids from coming into direct contact
with your skin or clothing.
If a service fluid is swallowed, contact a
physician immediately. Model
