Outside temperature indicator
The outside temperature indicator is
displayed in the multifunction display
(Y page 120).
GWarning!
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.
Fuel gauge
The fuel gauge is on the left-hand side of the
instrument cluster (Y page 28). Once the fuel
level has fallen below the reserve mark, the
yellow fuel tank reserve warning lamp 8
for the fuel reserve comes on.
Control system
Introduction
The control system is activated as soon as the
starter switch is in position 2.
The control system enables you to call up
information about your vehicle and to change
vehicle settings.
For example, you can use the control system
to find out when your vehicle is next due for
maintenance service, to call up statistical
data on your vehicle, and much more.
GWarning!
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.
The control system relays information to the
multifunction display.
