Distronic menu in the control system
In the Distronic menu you can read the cur-
rent settings for Distronic. What appears in
the multifunction display depends on
whether Distronic and the distance warn-
ing function are turned on or off.
Press buttonè orÿ repeatedly

Distronic brakes your vehicle with a maxi-
mum deceleration of 6.5 ft / s
2 (2 m / s
2).
This corresponds to about 20% of the maxi-
mum deceleration ability of your vehicle.
Distronic brakes the vehicle in an effort to
restore the preset distance or to maintain
the speed.

Useful features
Programming the integrated remote
control
Step 1:
Switch on the ignition (
page 36).
Step 2:
If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator lamp1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.
If you later wish to program a second
and/or third hand-held transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and be-
gin directly with step 3.Step 3:
Hold the end of the hand-held remote
control5 of the device you wish to
train approximately 2 to 5 in
(5 to12 cm) away from the signal trans-
mitter button (2, 3 or4) to be pro-
grammed, while keeping the indicator
lamp1 in view.
Step 4:
Using both hands, simultaneously
press the hand-held remote control
button6 and the desired signal trans-
mitter button (2, 3 or4). Do not
release the buttons until step 5 is com-
pleted.
The indicator lamp1 will flash, first
slowly and then rapidly.
When programming a garage door opener, it
is advised to park outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide
(CO), and inhaling it can cause unconscious-
ness and possible death.

337 Operation
Winter driving
Block heater* (Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at an
authorized Mercedes-Benz Center.
Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.Please observe the following guidelines
when using snow chains:
Use of snow chains is not permissible
with all wheel/tire combinations.
Snow chains should only be used on
the rear wheels. Follow the manufac-
turer’s mounting instructions.
Only use snow chains that are ap-
proved by Mercedes-Benz. Your
authorized Mercedes-Benz Center will
be glad to advise you on this subject.
Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.
!When driving with snow chains, always
select the raised level of the level con-
trol system Airmatic (
page 239).
Other settings may result in damage to
your vehicle.
iWhen driving with snow chains, you
may wish to deactivate the ESP
®
(
page 88) before setting the vehicle
in motion. This will improve the vehi-
cle’s traction.

473 Technical terms
Control system
The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to
adjust settings.
Cruise control
Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.
Distronic*
A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:
If there is no vehicle directly ahead,
the system operates in the same
way as conventional ->cruise con-
trol.
If a slower moving vehicle is ahead,
Distronic will reduce your vehicle
speed to the extent permitted by
reduced throttle and up to 20%
braking power to maintain the pre-
set minimum following distance.
DOT
(Department o
f Transportation)

page 332)
DTR
(->Distronic*)
Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine pro-
duced.Engine oil viscosity
Measurement for the inner friction
(viscosity) of the oil at different temper-
atures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
ESP
®(Electronic S
tability Pr
ogram)
Improves vehicle handling and direc-
tional stability.
ETD
(E
mergency T
ensioning D
evice)
Device which deploys in certain frontal
and rear collisions exceeding the sys-
tem’s threshold to tighten the seat
belts.
