Setting a lower speed
Briefly tip the cruise control lever in di-
rection of arrow2 (
page 221) to de-
crease vehicle speed in increments of
5 mph (Canada: 10 km/h).
The new speed is set.
The stored speed is displayed in the
multifunction display for approximately
five seconds (
page 221), and one or
two segments around the stored speed
come on the speedometer
(
page 219).Fine adjustment in 1 mph
(Canada: 1 km/h) increments
Faster

Briefly tip the cruise control lever in di-
rection of arrow4 (
page 221).Setting to last stored speed (“Resume”
function)

Briefly tip the cruise control lever in di-
rection of arrow4 (
page 221).
Distronic is set to the last stored
speed.

Remove your foot from the accelerator
pedal.
iWhen you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the rate of de-
celeration is too low.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed could cause an accident and/or seri-
ous injury you and others.

268 Controls in detailUseful featuresStep 12:
Confirm the garage door operation by
pressing the programmed integrated
signal transmitter button (2, 3
or4).
Step 13:

To program the remaining two buttons,
repeat the steps above starting with
step 3.Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the
programming procedures, replace step 4
with the following:Step 4:

Continue to press and hold the inte-
grated signal transmitter button (2,
3 or4) while you press and re-press
(“cycle”) your hand-held remote con-
trol transmitter6 every two seconds
until the frequency signal has been
learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.

Proceed with programming step 5 and
step 6 to complete.

(pass-through for electronic signals)
331.5 in (80 cm)
419.0 in (48 cm)
51.75 in (4.5 cm)Your vehicle is equipped with infrared re-
flecting glass which reduces the amount of
radiated heat entering the interior through
the windows.
The infrared reflecting glass also prevents
the transmission of signals through the
glass by in-vehicle electronic devices (e.g.
electronic toll collection devices).
To allow the use of these devices in the ve-
hicle, two infrared transparent areas
(1and2) are placed in the windshield.

280 OperationDriving instructionsStanding water
Passenger compartmentDriving abroad
Abroad, there is an extensive
Mercedes-Benz service network at your
disposal. If you plan to drive into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from
an authorized Mercedes-Benz Center.Control and operation of radio trans-
mitters
COMAND*, radio, and telephone*
!Do not drive through flooded areas or
water of unknown depth. Before driving
through water, determine its depth.
Never accelerate before driving into
water. The bow wave could force water
into the engine and auxiliary equip-
ment, thus damaging them.
If you must drive through standing wa-
ter, drive slowly to prevent water from
entering the passenger compartment
or the engine compartment. Water in
these areas could cause damage to
electrical components or wiring of the
engine or transmission, or could result
in water being ingested by the engine
through the air intake causing severe
internal engine damage. Any such dam-
age is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry ob-
jects.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle safely.
Only operate the COMAND (Cockpit Man-
agement and Data System), radio, or tele-
phone
1 if road, weather and traffic
conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
1Observe all legal requirements.

292 OperationEngine compartmentBe careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
Screw filler cap1 back on filler neck.
For more information on engine, see the
“Technical data” section (
page 429) and
(
page 431).
Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the automatic transmission.Active Body Control* (ABC*) fluid level
Regular fluid level check is not required. If
you notice fluid leaks or malfunction mes-
sages in the multifunction display, have an
authorized Mercedes-Benz Center check
the ABC-system.
Coolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze.
When checking the coolant level,

the vehicle must be parked on level
ground, and


the engine must be cool.
!Excess oil must be siphoned or drained
off. It could cause damage to the en-
gine and catalytic converter not cov-
ered by the Mercedes-Benz Limited
Warranty.


309 Operation
Tires and wheels
iThe recommended tire inflation pres-
sures for your vehicle can be found on
the tire placard located on the driver’s
door B-pillar. The tire inflation pres-
sures are not listed in the owner’s man-
ual.Warning!
G
The tire inflation pressure monitor does not
indicate a warning for wrongly selected tire
inflation pressures. Always adjust tire infla-
tion pressure according to the placard on
the driver’s door B-pillar or, if available, the
inside of the fuel filler flap.
The tire inflation pressure monitor is not
able to issue a warning due to a sudden dra-
matic loss of tire inflation pressure (e.g. tire
blowout caused by a foreign object). In this
case bring the vehicle to a halt by carefully
applying the brakes and avoiding abrupt
steering maneuvers.
iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the tire inflation pressure moni-
tor to malfunction.
Warning!
G
Follow recommend tire inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified load limit or vehicle capacity
weight as indicated on the placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout.

338 Practical hintsWhat to do if …?Lamps in instrument cluster
General information:If any of the following lamps in the instru-
ment cluster fails to come on during the
bulb self-check when switching on theignition, have the respective bulb checked
and replaced if necessary.Problem
Possible cause
Suggested solution
-
The yellow ABS malfunction in-
dicator lamp comes on while
driving.
The ABS has detected a malfunction and
has switched off. The BAS and the ESP are
also switched off (see messages in multi-
function display).
The brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as Parktronic*,
Distronic*, and the automatic transmission
may also be malfunctioning.

Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.

Read and observe messages in the mul-
tifunction display (
page 347).

Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions increas-
es the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS has switched off.
The battery may not be charged sufficiently.

Switch off electrical consumers that are
currently not needed, e.g. seat heat-
ing*.

If necessary, have the generator
(alternator) and battery checked.
When the voltage is above this value again,
the ABS is operational again.
