If the upward movement of the window is
blocked during the closing procedure, the
window will stop and open slightly.Stopping windows during Express-op-
eration

Press or pull the respective power win-
dow switch again.
Synchronizing power windows
The power windows must be synchronized

after the battery has been disconnect-
ed


if the power windows cannot be fully
opened (Express-open) or closed
(Express-close)
Synchronizing

Close all doors.

Switch on the ignition (
page 34).

Pull switch2 to 5 until the side win-
dows are completely closed.

Hold on to switches2 to 5 for ap-
proximately one second.
The power windows are synchronized.
Summer opening feature
If the weather is warm, you can ventilate
the vehicle before driving off by simulta-
neously:

opening the side windows


opening the tilt/sliding sunroof*


turning on the seat ventilation* for the
driver’s seat
Warning!
G
Driver’s door only:
If within five seconds switch is again pulled
past the resistance point and released, the
automatic reversal will not operate.!If the upward movement of the window
is blocked during the closing proce-
dure, the window will stop and open
slightly.
Remove the obstruction, pull the re-
spective power window switch again
past the resistance point and release.
If the window still does not close when
there is no obstruction, pull and hold
the respective power window switch.
The side window will then close without
the obstruction sensor function.
iThe seat ventilation* for the driver’s
seat is automatically set to the highest
level if activated via summer opening
feature.

232 Controls in detailDriving systemsDistronic*
When activated, the Distronic adaptive
cruise control system increases driving
convenience afforded by the cruise control
during travel on expressways and other
major roads.

If the Distronic distance sensor detects
a slower moving vehicle directly ahead,
your vehicle speed will be reduced so
that you follow that vehicle at a preset
distance.


If there is no vehicle directly ahead of
you, Distronic will function in the same
way as cruise control (
page 236).
Warning!
G
Distronic adaptive cruise control is no sub-
stitute for active driving involvement. It does
not react to stationary objects, nor recog-
nize or predict the curvature and lane layout
or the movement of vehicles ahead.
Distronic can only apply a maximum of 20%
of the vehicle’s braking power.
It is the driver’s responsibility at all times to
be attentive to traffic and road conditions
and to provide the steering, braking and oth-
er driving inputs necessary to retain control
of the vehicle.Warning!
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. However, it
is not intended to, nor does it, replace the
need for extreme care. The responsibility for
the vehicle speed and the distance to the ve-
hicle ahead, including most importantly
brake operation to assure safe stopping dis-
tance, always rests with the driver.
Distronic cannot take street and traffic con-
ditions into account.
Warning!
G
Distronic requires familiarity with its opera-
tional characteristics. We strongly recom-
mend that you review the following
information carefully before operating the
system.iUSA only:
This device complies with Part 15 of
the FCC Rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful
interference, and
(2) this device must accept any inter-
ference received, including interfer-
ence that may cause undesired
operation.
Any unauthorized modification to this
device could void the user’s authority
to operate the equipment.

242 Controls in detailDriving systemsThe most likely cause for a malfunctioning
system is a dirty sensor (located behind
the hood grille), especially at times of snow
and ice or heavy rain. In such a case,
Distronic will switch off, and the message Currently unavailable See Operator’s
Manual
appears in the multifunction
display.
For cleaning and care of the Distronic sen-
sor, see “Cleaning the Distronic* system
sensor cover” (
page 347).Turns and bends
In turns or bends, Distronic may not detect
a moving vehicle in front, or it may detect
one too soon. This may cause your vehicle
to brake late or unexpectedly.
iIf the message

See Operator’s Manual
disappears
during driving and the last speed stored
flashes for approximately five seconds,
the dirt (e.g. slush) has dissolved;
Distronic works again.

294 OperationDriving instructionsCatalytic converter
Your vehicle is equipped with monolith-
ic-type catalytic converters, an important
element in conjunction with the oxygen
sensors to achieve substantial control of
the pollutants in the exhaust emissions.
Keep your vehicle in proper operating con-
dition by following our recommended
maintenance instructions as outlined in
your Maintenance Booklet.
Emission control
Certain systems of the engine serve to
keep the toxic components of the exhaust
gases within permissible limits required by
law.
These systems, of course, will function
properly only when maintained strictly ac-
cording to factory specifications. Any ad-
justments on the engine should, therefore,
be carried out only by qualified
Mercedes-Benz Center authorized techni-
cians. Engine adjustments should not be
altered in any way. Moreover, the specified
service jobs must be carried out regularly
according to Mercedes-Benz servicing re-
quirements. For details refer to the
Maintenance Booklet.
!To prevent damage to the catalytic con-
verters, use only premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel
may reach the catalytic converter,
causing it to overheat and potentially
start a fire.
Warning!
G
As with any vehicle, do not idle, park or op-
erate this vehicle in areas where combusti-
ble materials such as grass, hay or leaves
can come into contact with the hot exhaust
system, as these materials could be ignited
and cause a vehicle fire.

318 OperationTires and wheelsChecking tire inflation pressure
Regularly check your tire inflation pressure
at least once a month.
Check and adjust the tire inflation
pressure when the tires are cold. The tires
can be considered cold if the vehicle has
been parked for at least three hours or
driven less than one mile (1.6 km).
If you check the tire inflation pressure
when the tires are warm (the vehicle has
been driven for several miles or sitting less
than three hours), the reading will be
approximately 4 psi (0.3 bar) higher than
the cold reading. This is normal. Do not let
air out to match the specified cold tire in-
flation pressure. Otherwise, the tire will be
underinflated.
Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
Remove the cap from the valve on one
tire.

Firmly press a tire gauge onto the
valve.

Read tire inflation pressure on tire
gauge and check against the recom-
mended tire inflation pressure on the
placard on the driver’s door B-pillar
(page 316). If necessary, add air to
achieve the recommended tire inflation
pressure.

Install the valve cap.

Repeat this procedure for each tire.Checking tire inflation pressure elec-
tronically*
The tire pressure monitoring system* only
functions on wheels that are equipped with
the proper electronic sensors. It monitors
the tire inflation pressure, as selected by
the driver, in all four tires. A warning is is-
sued to alert you to a decrease in pressure
in one or more of the tires.
You can call up the tire pressure monitor-
ing display using the control system
(
page 167).
iIf you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.
iAfter you have reactivated the tire
pressure monitoring system*, the cur-
rent tire inflation pressures will only be
shown after a few minutes’ driving
time.
During this time, you will see the follow-
ing message in the display:Tire pressure

displayed only
after driving
a few mins.

Vehicle care
Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.Cleaning the Distronic* system sensor
