Instrument cluster
A full view illustration of the instrument
cluster can be found in the “At a glance”
section of this manual (
page 26).
You can change the instrument cluster
settings in the instrument cluster submenu
of the control system (
page 168).
Multifunction display
The multifunction display is activated when
you:

open a door

switch on the ignition

switch on the exterior lamps
The language setting for the multifunction
display can be changed via control system
(
page 168).
Warning!G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warning/
indicator lamps, malfunction/warning mes-
sages or the failure of any systems. Driving
characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.

Coolant temperature gauge
The coolant temperature gauge is on the
left side in the instrument cluster
(
page 26).
iThe instrument cluster illumination is
dimmed or brightened automatically to suit am-
bient light conditions.
The instrument cluster illumination will also be
adjusted automatically when you switch on the
vehicle’s exterior lamps.
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 and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing 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.

Tachometer
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 indicated in the
multifunction display (
page 151).
!Excessive coolant temperature triggers a
warning in the multifunction display
(
page 402).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C), i.e. in
the red zone of the coolant temperature gauge.
Doing so may cause serious engine damage
which is not covered by the Mercedes-Benz Lim-
ited Warranty.
iDuring severe operating conditions,
e.g. stop-and-go traffic, the coolant temperature
may rise close to 248°F (120°C), i.e. close to
the red zone of the temperature gauge.
!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.

150 Controls in detail
Instrument cluster
The outside temperature sensor is located
in the front bumper area. Due to its loca-
tion, the sensor can be affected by road or
engine heat during idling or slow driving.
Therefore, the accuracy of the displayed
temperature can only be verified by com-
parison to a thermometer placed next to
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.Fuel gauge
The fuel gauge is on the left-hand side of
the instrument cluster (
page 26). Once
the fuel level has fallen below the reserve
mark, the yellow fuel tank reserve warning
lamp 4 for the fuel reserve comes on
(
page 380).

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
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
(approximately 14 m) every second.

Depending on the selected menu
(
page 155), pressing the buttons on the
multifunction steering wheel will alter what
is shown in the multifunction 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.
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
“Submenus in the Settings menu”
(
page 166).
It is helpful to think of the menus, and the
functions within each menu, as being
arranged in a circular pattern.The number of menus available in the sys-
tem depends on which optional equipment
is installed in your vehicle.
