What you should know at the gas station
Fuel supplyOpen flap by pushing near front (arrow). Turn fuel cap
to the left and hold on to it until possible pressure in
tank has been released, then remove cap. Failure to
remove slowly could result in personal injury.
Manual release of fuel filler flap, see page 296.
Fuel
To prevent fuel vapors from escaping into open air, fully
insert filler nozzle unit. Only fill fuel tank until the filler
nozzle unit cuts out – do not top up or overfill.
Leaving the engine running and the fuel cap open can
cause the “CHECK ENGINE” lamp to illuminate.
Fuel tank capacity approx. 16.4 US gal (62.0 l).
This includes approx. 2.1 US gal (8.0 l) reserve. Use
premium unleaded gasoline: Posted Octane Index 91
(Average of 96 RON/86 MON).
Wa r n i n g !
Gasoline is highly flammable and poisonous. It
burns violently and can cause serious injury.
Whenever you are around gasoline, avoid inhaling
fumes and skin contact, extinguish all smoking
materials. Never allow sparks, flame or smoking
materials near gasoline!
Wa r n i n g !
Overfilling of fuel tank may result in creating
pressure in the system which could cause a gas
discharge such as the gas spraying back out upon
removing the filler nozzle which could cause
personal injury.

Malfunction and indicator lamps
in the instrument cluster
General information:
If a bulb in the instrument cluster fails to light up
during the bulb self-check when turning the electronic
key in steering lock to position 2, have it checked and
replaced if necessary.
On-board diagnostic system
Check engine malfunction indicator lamp
Engine malfunction indicator lamp. If the
“CHECK ENGINE” malfunction indicator
lamp comes on when the engine is running,
it indicates a malfunction of the fuel management
system, emission control system, systems which impact
emissions, or the fuel cap is not closed tight (check the
fuel cap). If the “CHECK ENGINE” lamp is illuminated
continuously and the vehicle is driving normally, you
may still drive the vehicle, however, in all cases, we
recommend that you have the system checked at your
authorized Mercedes-Benz Center as soon as possible.
If the “CHECK ENGINE” lamp comes on continuously
and / or the vehicle is not driving normally (e.g.
malfunction of the fuel management system or running out of fuel), serious damage can occur to the emission
system. Please contact your authorized Mercedes-Benz
Center immediately.
The Sequential Multiport Fuel Injection (SFI) control
module monitors emission control components that
either provide input signals to or receive output signals
from the control module. Malfunctions resulting from
interruptions or failure of any of these components are
indicated by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster and are
simultaneously stored in the SFI control module.
If the “CHECK ENGINE” malfunction indicator lamp
comes on, have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
With some exceptions, the control module switches off
the “CHECK ENGINE” malfunction indicator lamp if the
condition, causing the lamp to come on, no longer exists
during three consecutive cycles. See also page 226 for
fuel cap placement warning.
An on-board diagnostic connector is located in the
passenger compartment near to the parking brake
pedal, allowing the accurate identification of system
malfunctions through the readout of diagnostic trouble
codes.

Except Canada
Canada only
When the brake warning lamp and message appear
while the engine is running, this means:
•there is insufficient brake fluid in the reservoir
(engine running and parking brake released), or
•the parking brake is set (engine running).Note:
If you find that the brake fluid in the brake fluid
reservoir has fallen to the minimum mark or below,
have the brake system checked for brake pad thickness
and leaks.
BRAKE
Wa r n i n g !
Driving with the brake warning lamp illuminated
can result in an accident. Have your brake system
checked immediately if the brake warning lamp
stays on. Don’t add brake fluid before checking the
brake system. Overfilling the brake fluid reservoir
can result in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You can be
seriously burned.

Supplemental restraint system (SRS) indicator lamp
The operational readiness of the airbag
system is verified by the indicator lamp
“SRS” in the instrument cluster when
turning the electronic key in steering lock to position 1
or 2. If no malfunction is detected, the lamp will go out
after approximately 4 seconds; after the lamp goes out,
the system continues to monitor the components and
circuitry of the airbag system and will indicate a
malfunction by coming on again.
See page 61 for notes on airbags, see page 60 for belt
tensioners and page 69 for infant and child seat
restraint.Fuel reserve and fuel cap placement warning
When the warning lamp (1) comes on after starting the
engine, or if it comes on while driving, it indicates that
the fuel level is down to the reserve quantity of
approximately 2.1 gal (8 liters).
The warning lamp blinks when the fuel cap is not
closed, or a fuel system leak has been detected.
Retighten cap and see if lamp goes out after restart and
next OBD selfcheck.
If the warning lamp continues to blink after closing the
fuel cap correctly, have the fuel system checked at your
authorized Mercedes-Benz Center as soon as possible.
Leaving the engine running and the fuel cap open can
also cause the “CHECK ENGINE” lamp to illuminate, see
page 224.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have the
system checked; otherwise the “SRS” may not be
activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy
unexpectedly and unnecessarily which could also
result in injury.SRS

The yellow ESP warning lamp in the
speedometer dial comes on with the
electronic key in steering lock position 2.
It should go out with engine running.
See page 216 if the warning lamp lights up or flashes
when the vehicle is moving.
BAS / ESP malfunction indicator lamp
The malfunction indicator lamp for the ESP
is combined with that of the BAS.
The yellow BAS/ESP malfunction indicator
lamp in the instrument cluster comes on with the
electronic key in steering lock position 2. It should go
out with the engine running.
If the BAS/ESP malfunction indicator lamp remains
illuminated with the engine running, see page 212 for
notes on the brake assist (BAS) and page 216 for notes
on the electronic stability program (ESP).ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in steering lock position 2 and
should go out with the engine running.
When the ABS malfunction indicator lamp and the
malfunction message in the instrument cluster remains
illuminated while the engine is running, it indicates
that the ABS has detected a malfunction and has
switched off. In this case, the brake system functions in
the usual manner, but without antilock assistance.
With the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lamps and the
ABS malfunction message in the multifunction display
come on with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
See page 214 for notes on the antilock brake system
(ABS).
