Resetting trip odometer
Make sure you are viewing the trip
odometer display (
page 157).
If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel (
page 158) repeatedly until
the trip odometer appears in the multi-
function display.
Press and hold reset button 2

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 indicated in the
multifunction display (
page 157).
!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
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the
road surface 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 (
page 40) or as
soon as the KEYLESS-GO start/stop
button* is in position1 (
page 41). The
control system enables you to

call up information about your vehicle

change vehicle settings
For example, you can use the control
system to find out when your vehicle is
next due for maintenance service, to set
the language for messages in the instru-
ment cluster display, and much more.

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.

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.
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.
