Speedometer
In vehicles with Active Distance Assist
DISTRONIC, there are illuminated segments on
the speedometer dial.
These segments show you what speed range is
available:
Variable limiter activated (
R
The segments light up from the start of the
scale to the selected limit speed.
Active Distance Assist DISTRONIC switched
R
on ( page 164)
/
One or two segments light up in the saved
speed range.
Active Distance Assist DISTRONIC detects a
R
vehicle in front.
The segments light up from the speed of the
vehicle in front up to the saved speed.
You can show the speed as a digital speedometer
on the display as well.
If you change your vehicle's wheel size, check its
assignment to the wheel size group
( page 267). If the assignment changes with‐
/
out recoding the control units in the vehicle, the
speedometer will not display the speed accu‐
rately. The current vehicle speed may then be
higher than the speed shown by the speedome‐
ter. Driving and driving safety systems may then
be operationally impaired or may detect a mal‐
function and switch themselves off.
In some countries, an audible signal will sound
and/or a message will appear on the display

Coolant temperature display
& WARNING Risk of burns when opening
the bonnet
If you open the bonnet when the engine has
overheated or when there is a fire in the
engine compartment, the following situations
may occur:
You could come into contact with hot
R
gases.
You could come into contact with other
R
hot, escaping operating fluids.
Before opening the bonnet, allow the
#
engine to cool down.
In the event of a fire in the engine com‐
#

the instrument cluster's rev counter.
During normal driving and if the coolant level is
correct, the display is permitted to rise to 120°C.
