Press buttonè orÿ repeatedly
until you see the standard display in
the multifunction display (

Warning!G

Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously
burned.

Steam from an overheated engine can
cause serious burns which can occur
just by opening the hood. Stay away
f r o m t h e e n g i n e i f y o u s e e o r h e a r s t e a m
coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.
!Excessive coolant temperature triggers the
coolant temperature warning lamp (
page 306)
and a warning in the multifunction display
(
page 335).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C). Doing so
may cause serious engine damage which is not
covered by the Mercedes-Benz Limited
Warranty.
iDuring severe operating conditions, e.g.
stop-and-go traffic, the coolant temperature may
rise close to 248°F (120°C).

Tachometer
The red marking on the tachometer
(
page 29) denotes excessive engine
speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature is displayed in
the left or right multifunction display
(
page 117), depending on the setting for
the standard display (
page 132). The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-
ature can only be verified by comparison to
a thermometer placed next the sensor, not
by comparison to external displays, e.g.
bank signs, etc.
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
!Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

display, and much more.
The control system relays information to
the multifunction display.
Multifunction display
The multifunction display consists of the
display fields in the speedometer and the
tachometer. In its default state, the left
display field shows the outside tempera-
ture and main odometer, while the trip
odometer and the clock appears in the
right display field. This default setting is
referred to as the standard display.

Warning!G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions
permit it to be done safely.
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.

Depending on the selected menu, pressing
the buttons on the multifunction steering
wheel will alter what appears in the
multifunction display.
The information available in the multifunc-
tion display is arranged in menus, each
containing a number of functions or
submenus.
The individual functions are then found
within the relevant menu (radio or CD op-
erations under
AUDIO, for example). These
functions serve to call up relevant informa-
tion or to customize the settings for your
vehicle.It is helpful to think of the menus, and the
functions within each menu, as being
arranged in a circular pattern.

If you press buttonè orÿ
repeatedly, you will pass through each
menu one after the other.

If you press buttonk orj
repeatedly, you will pass through each
function display, one after the other, in
the current menu.In the
Settings menu, instead of functions
you will find a number of submenus for
calling up and changing settings. For
instructions on using these submenus, see
“Settings menu” (
page 129).
The number of menus available in the sys-
tem depends on which optional equipment
is installed in your vehicle.
The menus are described on the following
pages.
