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.

! 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

covered by the Mercedes-Benz Limited
Warranty.
For further information contact an
authorized Mercedes-Benz Center.
Notes on checking engine oil level

be parked on level ground and the vehicle
must have been stationary for at least
5 minutes with the combustion engine turned
off. Checking engine oil level
Before opening the hood do the following:
X Engage the parking brake.
X Shift the automatic transmission into park
position P.
X Switch off the ignition.
The READY indicator (Y page 16) in the
instrument cluster goes out.
X Remove the SmartKey from the starter
switch or remove the SmartKey with
KEYLESS-GO from the vehicle.
X Observe the safety notes on the danger of

charge the 12-volt battery. Jump starting
When the 12-volt battery or the high-voltage
battery is discharged, the combustion engine
can be started with jumper cables and the
battery of another vehicle. Observe the following:
R
Jump starting should only be performed
when the combustion engine and the
catalytic converter are cold.
R Do not jump start if the battery is frozen.
Let the battery thaw out first.
R Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a more powerful battery could damage
the vehicle’s electrical system, which is not
covered by the Mercedes-Benz Limited
Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
R Should the battery be drained completely,
let the donating power source charge the
vehicle for several minutes before
reattempting the starting process.
i Jumper cables and additional information
on jump starting are available at any
authorized Mercedes-Benz Center.
! Jump starting should only be performed
using the jump-start terminals located in
the engine compartment.
Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick-charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation. Practical hints
