Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 28). Important safety notes
G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for
the country in which you are currently driving when operating the on-board computer.
PLUG-IN HYBRID vehicles only: G
WARNING
If the instrument cluster has failed or there is a malfunction, you may not know about
safety-related function restrictions. The oper- ating safety of your vehicle may be affected.
There is a risk of an accident.
Immediately stop the vehicle while paying
attention to the traffic conditions and consult
a qualified specialist workshop.
All vehicles, except PLUG-IN HYBRID vehi- cles: G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as
possible. Contact a qualified specialist work-
shop.
The on-board computer only shows messages
or warnings from certain systems in the mul- tifunction display. You should therefore make
sure your vehicle is operating safely at all
times.
For an overview, see the instrument cluster
illustration (Y page 34). Displays and operation

brightness will depend upon the brightness
of the ambient light.
i The light sensor in the instrument cluster
automatically controls the brightness of
the multifunction display.
In daylight, the displays in the instrument
cluster are illuminated. A dimming function
is not possible in daylight. Speedometer with segments
The speedometer is divided into segments on vehicles with DISTRONIC PLUS.
The segments in the speedometer indicate
which speed range is available.
R Cruise control activated (Y page 230):
The segments light up from the stored
speed to the type-tested maximum speed.
R Variable SPEEDTRONIC activated
(Y page 233):
The segments light up from the start of the
scale to the selected limit speed.
R DISTRONIC PLUS activated (Y page 236):
One or two segments in the set speed
range light up.
R DISTRONIC PLUS detects a vehicle in front
moving more slowly than the stored speed:
The segments between the speed of the
vehicle in front and the stored speed light
up. Rev counter
! Do not drive in the overrevving range.
Doing so will damage the engine.
The red band in the rev counter indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
PLUG-IN HYBRID vehicles: when you select
the E-MODE operating mode, the display in
the instrument cluster switches from rev
counter to wattmeter (Y page 289). Outside temperature display
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the measured air tempera-
ture and not the road surface temperature.
The outside temperature display is in the mul- tifunction display (Y page 315).
Changes in the outside temperature are dis-
played after a short delay. Coolant temperature gauge
G
WARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking ser-
vice products. There is a danger of injury.
Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in the engine compartment, leave the bonnet
closed and notify the fire brigade.
All vehicles except PLUG-IN HYBRID vehicles: the coolant temperature gauge is in the lower
section of the rev counter (Y page 34).
PLUG-IN HYBRID vehicles: the multifunction
display shows the coolant temperature in the
Coolant Coolant submenu (Y page 327).
At high outside temperatures and when driv-
ing uphill, the coolant temperature may rise
to the end of the scale.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †. Displays and operation
