until the
coolant temperature gauge appears. During severe operating conditions and
stop-and-go city traffic, the coolant tem-
perature may rise close to 248°F (120°C).
The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Trip odometer
Check to see that the trip odometer
and main odometer (

pear in the multifunction display.
Press and hold the reset knob on the in-
strument cluster (
page 22) until the
trip odometer is reset.
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.

a warning in the multifunction display
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the

104 Controls in detailInstrument clusterOutside temperature indicatorThe 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. This
means that 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.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.

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 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 (approximate-
ly 13.5 m) every second.

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
repeatedly, you will pass through each
menu one after the other.
If you press button
k
or
j
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 in-
structions on using these submenus, see
the “Settings menu” section (
page 114).
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.

G
Malfunction and warning messages are only
indicated for certain systems and are inten-
tionally not very detailed. The malfunction
and warning messages are simply a remind-
er with respect to the operation of certain
systems and do not replace the owner’s
and/or driver’s responsibility to maintain
the vehicle’s operating safety by having all
required maintenance and safety checks
performed on the vehicle and by bringing
the vehicle to an authorized Mercedes-Benz
Center to address the malfunction and
warning messages (
page 252).
