cluster, see “Instrument cluster”
(page 26).
The instrument cluster is activated when

press the reset button (
page 26)
switch on the exterior lamps
Opening a door will activate the instrument
cluster only for about 30 seconds.
You can change the instrument cluster set-
tings in the Instrument cluster submenu of
the control system (
page 156).Adjusting instrument cluster

1Reset buttoni
The instrument cluster illumination is
dimmed or brightened to suit ambient light con-
ditions.
Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, do so with
added caution. Visit an authorized
Mercedes-Benz Center as soon as possible.

Coolant temperature gauge
Trip odometer
Make sure you are viewing the trip
odometer display (
page 139).
If it is not displayed, press the j or
k button on the multifunction
steering wheel repeatedly until the trip
odometer appears.
Press and hold reset button1
(page 136) until the trip odometer is
reset.
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
from the engine if you see or hear steam
coming from it.
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 337)
and a warning in the multifunction display
(
page 371).
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.
i
During severe operating conditions, e.g.
stop-and-go traffic, the coolant temperature may
rise close to 248°F (120°C).

138 Controls in detailInstrument clusterTachometer
The red marking on the tachometer de-
notes 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 26), depending on the setting
(page 156).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.

Control system
Control system
The control system is activated as soon
as the SmartKey in the starter switch is
turned to position1 or as soon as the
KEYLESS-GO start/stop button is in
position 1. The control system enables
you to
call up information about your vehicle
change vehicle settings
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to set the language for
messages in the instrument cluster dis-
play, 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
multifunction display shows the main
odometer and the outside temperature,
while the trip odometer appears in the
right multifunction display. 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,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit 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
(approximately 14 m) every second.

The displays in the multifunction display
and the settings in the control system are
controlled by the buttons on the multifunc-
tion steering wheel.
Depending on the selected menu, pressing
the buttons on the multifunction steering
wheel will alter what appears in the multi-
function display.
The information available in the multifunc-
tion display is arranged in menus, each
containing a number of functions or sub-
menus.

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 ar-
ranged in a circular pattern.
If you press button è or ÿ re-
peatedly, you will pass through each
menu one after the other.
If you press button k or j re-
peatedly, 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 in-
structions on using these submenus, see
“Settings menu” (page 153).
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.
