Coolant temperature gaugeDuring severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture 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
Make sure you are viewing the trip
odometer display (
page 135).
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 132) 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.
Warning!
G
Driving when your engine is badly over-
heated can cause some fluids which
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.
Steam from an overheated engine can
cause serious burns an 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 336) and a warning in the
multifunction display (
page 366).
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.

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 posi-
tion 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 digital speedometer,
while the trip odometer appears in the
right multifunction display. This default
setting is referred to as the standard dis-
play.

mit it to be done safely.
