Parking assist (Parktronic)
(optional)
The Parktronic system assists the driver during parking
maneuvers. It visually and audibly indicates the relative
distance between the vehicle and an obstacle.
The front area of the vehicle is monitored when driving
forward. When reversing, the front as well as the rear
areas are monitored.
With the electronic key in steering lock position 2,
Parktronic engages automatically at speeds up to
approximately 10 mph (15 km / h) and deactivates
during higher speeds.
Parktronic can be switched off by a control switch
located in the center console. It engages automatically
again when starting the engine.
See page 236 for parktronic switch.
Wa r n i n g !
Parktronic is a supplemental system. It is not
intended to nor does it replace the need for extreme
care. The responsibility during parking and other
critical maneuvers rests always with the driver.Special attention must be paid to objects having
smooth surfaces or low silhouettes (e.g. trailer
couplings, painted posts, or street curbs). Such
objects may not be detected by the system and can
damage the vehicle.The operational function of the Parktronic can be
affected by dirty sensors, especially at times of
snow and ice. See page 311 for notes on cleaning
the parktronic system sensors.Interference caused by other ultrasonic signals
(e.g. working jackhammers or the air brakes of
trucks) can cause the system to send erratic
indications, and should be taken into
consideration.

1Sensors located in bumper
(front bumper shown)A total of 10 sensors (1) monitor the vehicle’s front and
rear areas. Six sensors are located in the front bumper,
four sensors in the rear bumper.
For proper operation of the Parktronic always keep the
sensors clean, especially at times of snow and ice.
See page 311 for instructions on cleaning the sensors in
the bumpers.

Warning indicators
1Frame
2SegmentsVisual and audible signals indicate to the driver the
relative distance between the vehicle and an obstacle.
Warning indicators for the front area are located above
the center air outlets in the dashboard.
Warning indicators for the rear area are located in the
rear passenger compartment lamp.
The frames are illuminated when the Parktronic is
engaged.
Each warning indicator has 6 yellow and 2 red
segments.
As soon as the sensors detect an obstacle, one or more
segments light up, depending on the distance. An
intermittent acoustic warning will also sound as the
seventh segment lights up and a constant acoustic
warning lasting a maximum of 3 seconds will sound for
the eighth segment.

The obstacle may not be recognized if outside the
shaded sensor field, and no longer be indicated when
approaching it any closer (warning indicators go out).
Parktronic malfunction
All red segments of the warning indicators light up, and
a warning sounds for 3 seconds, if Parktronic does not
function properly.
A dirty sensor could be the reason. (See page 311 for
instructions on cleaning the sensors in the bumpers.)
After cleaning the sensors, turn electronic key in
steering lock to position 2. If the defect continues to be
displayed, have the system checked at your authorized
Mercedes-Benz Center.Parktronic switch

237 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 302 for notes on fuel filler flap, manual
release.
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 242 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.

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, 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 244 for
fuel cap placement warning.
