(optional)
When activated the Distronic system increases driving
convenience, for example over long distances, as it
automatically maintains a speed set by the driver by
actively regulating the throttle setting. It also maintains
within certain limitations a preset distance to a vehicle
ahead.
With Distronic switched off, the multifunction display
continues to show the distance to the vehicle ahead, if
so selected, see page 266.
The distance notification function can be activated
separately, see page 264.
In Distronic mode, if the distance sensor detects a
slower moving vehicle directly ahead, your vehicle
speed will be reduced to the extent permitted by
red uced t hrottl e a nd up to 20% of veh icl e bra king power,
so that you follow that vehicle at a preset distance, see
page 265.
Maximum range of detection is approximately 500 ft.
(150 m).Any given speed between 25 mph (Canada: 30 km/h)
and 110 mph (Canada: 180 km/h) can be maintained
with the Distronic by operating the control lever on the
steering column.
Wa r n i n g !
Distronic is a convenience system, its speed
adjustment reduction capability is intended to
make cruise control more effective and usable
when traffic speeds vary. It is not, however,
intended to nor does it replace the need for extreme
care. The responsibility for the vehicle speed and
the distance to the vehicle ahead, including most
importantly brake operation to assure safe stopping
distance, rests always with the driver.Wa r n i n g !
Distronic requires familiarity with its operational
characteristics. We strongly recommend that you
review the following information carefully before
operating the system.

cluster displayPractical hints Car care Index Driving with Distronic activated
With the electronic key in starter switch position 2, the
distance warning lamp l in the speedometer dial comes
on and goes out with the engine running.
If th e distance sensor detects a slower veh ic le moving in
front, your vehicle speed will be reduced by
deceleration and braking of up to 20% of the vehicle
braking capacity, so that you follow the vehicle ahead at
the preset distance, see page 265. Segments in the
speedometer illuminate to indicate the speed range from the speed of the vehicle in front up to your
vehicle’s selected speed. See also page 266 for notes on
the multifunction displays.
Wa r n i n g !
Distronic brakes (up to 20% of vehicle braking
power) the vehicle to restore the preset distance or
to maintain the speed. The brake pedal is
automatically retracted as this happens.Keep driver’s foot area clear at all times, including
the area under the brake pedal. Objects stored in
this area may impair pedal movement which could
interfere with the braking ability of the Distronic
system.Do not place you r foot under th e brake pedal – you r
foot could become caught.

279 Parking system
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Parking assist (Parktronic)
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 or with the gear selector lever
in position “N”, the front as well as the rear areas are
monitored.
With the electronic key in starter switch 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 283 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 378 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.

1 One or more tires def late rapidly or tire pressure is already below
minimum value. Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers. For reference on changing
wheels, see page 337.
2 The tire pressure on one or more tires is already below minimum
value. Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. For reference on changing
wheels, see page 337.
3 For tire inflation pressure monitor, see page 150.4 Tire pressure in one or more tires is low. Check and correct tire
pressure, see page 345.
5 The tire pressure monitor cannot be activated with the engine
running. Turn off the engine and repeat activation, see page 151.
6 When the message appears after starting the engine, the tire
inflation pressure on all road wheels should be checked and
corrected according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 345.
The tire inflation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 151.
7 The tire inflation pressure monitor system is unable to monitor the
tire pressure due to the presence of several wheel electronics in
the vehicle (e.g. a deflated road wheel in the trunk), or nearby
radio interference source, or excessive wheel sensor temperatures,
or unrecognized wheel sensors mounted.
8 The tire inflation pressure monitor is defective or a wheel without
proper sensor was installed. Visit your authorized Mercedes-Benz
Center.Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire will cause excessive heat build-up and possibly
a fire.
