The yellow ESP warning lampv in the speedometer
dial comes on with the electronic key in starter switch
position 2. It should go out with the engine running.
If the ESP warning message is displayed, a malfunction
has been detected in the system. Only partial engine
output will be available.
Have the ESP checked at your authorized
Mercedes-Benz Center as soon as possible.
For ESP warning message, see page 288.
With the ABS malfunctioning, the ESP is also switched
off.
Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lamp in speedometer
dial comes on). For this reason, all wheels, including the
spare wheel, must have the same tire size. When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and / or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the ESP warning message may
be displayed with the engine running.
Turn steering wheel completely to the left and then to
the right. The ESP warning message should go out.

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.
See page 354 for manual release of fuel filler flap.
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, see
page 283 for notes on the “CHECK ENGINE” lamp.
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.

When turning the electronic key in starter
switch to position 1 the indicator lamp “SRS”
in the instrument cluster comes on. If no
fault is detected, the lamp will go out after
approximately 4 seconds.
When turning the electronic key in starter switch to
position 2 the indicator lamp “SRS” in the instrument
cluster comes on. If no fault is detected, the lamp will go
out when the engine is running.
The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the electronic key in starter switch
to position 1 or 2.
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 72 for notes on airbags, see page 70 for belt
tensioners and page 62 for infant and child seat
restraint.
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.

Fuel reserve warning
1Fuel reserve indicatorWhen 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 US gal (8 liters). In addition to the
warning lamp, the message “RESERVE FUEL” –“VISIT
FUEL STATION” appears in the multifunction display.
See page 278 for notes on refueling the vehicle.
After refueling the vehicle, the message
“1 MALFUNCTION” appears in the multifunction
display when turning the electronic key in starter
switch to position 2. This malfunction message has to be
cleared, see page 119 for notes on the malfunction /
warning message memory.

The ABS malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in starter switch position 2
and should go out with the engine running.
When the ABS malfunction indicator lamp symbol and
warning 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.
A malfunctioning ABS control unit can possibly affect
the operation of other systems (e.g. Navigation,
Automatic transmission). Be guided accordingly with
respect to the use of those systems and have the system
checked at your authorized Mercedes-Benz Center as
soon as possible.With the ABS malfunctioning, the BAS and ESP are also
switched off. The malfunction indicator lamps and
malfunction messages 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 272 for notes on antilock brake system (ABS).

Electronic stability program (ESP) — warning lamp
The yellow ESP warning lamp in the
speedometer dial comes on with the
electronic key in starter switch position 2.
It should go out with engine running.
If the ESP malfunction indicator lamp remains
illuminated with the engine running, a malfunction has
been detected in the system. Pressing the accelerator
pedal will require greater effort. Only partial engine
output will be available.
See electronic stability program (ESP) on page 274 if the
warning lamp lights up or flashes when the vehicle is
moving.Seat belt nonusage warning lamp
With the electronic key in starter switch
position 2, the seat belt nonusage warning
lamp comes on, and a warning sounds for a
short time if the drivers seat belt is not fastened.
After starting the engine, the seat belt nonusage
warning lamp blinks for a brief period to remind the
driver and passengers to fasten seat belts.
