The brightness of the instrument illumination is set automatically depending
on the ambient lighting throughout. If the visibility is poor and the lights are
not on, the brightness of the instrument lighting reduces to alert the driver to
switch on the lights in due time.
The brightness of the instrument lighting can be activated/deactivated in the
» Owner´s Manual - Infotainment .
Rev counter
The tachometer
1
» Fig. 17 on page 28 or » Fig. 18 on page 28 shows the ac-
tual engine speed per minute.
The beginning of the red scale range of the tachometer indicates the maxi-
mum permitted engine speed of a driven-in and operating warm engine.
You should shift into the next highest gear before the red scale of the revolu- tion counter is reached, or select mode D / S on the automatic gearbox.
The gear recommendation is important to note in order to maintain the opti-
mum engine speed » page 38.
CAUTION
The rev counter pointer may only move into the red area for a short time - oth-
erwise risk of engine damage!123456728Using the system

, the engine has not yet reached its
operating temperature. Avoid high speeds and high engine loads.
Operating range - the pointer is in the range

High temperature range - the pointer is in the range
C
. The coolant tempera-
ture is too high. The warning light illuminates in the instrument cluster

Fuel gauge
Fig. 20
Fuel gauge: in the instrument cluster / the display of the instru-
ment cluster
The display » Fig. 20 only works if the ignition is switched on.
The fuel tank has a capacity of about 55 litres.
If the fuel level reaches the reserve level A or B, the warning light illumi-
nates in the instrument cluster » page 33.WARNINGFor the vehicle systems to function correctly, and thus for safe driving,
there must be sufficient fuel in the tank. Never drain the fuel tank com-
pletely – risk of accident!
CAUTION
Never drive until the fuel tank is completely empty! Irregular supply of fuel can
cause misfiring, which can result in damage to parts of the engine and the ex-
haust system.
Note
■ After filling up, it can occur that during dynamic driving (e.g. numerous
curves, braking, driving downhill and climbing a steep hill) the fuel gauge indi-
cates a fraction less.■
The arrow
next to the symbol
within the fuel gauge displays the installa-
tion location of the fuel filler on the right side of the vehicle.

The warning lights in the instrument cluster indicate certain functions or
faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test. If the tested systems are OK, the corresponding warning lights go
out a few seconds after switching on the ignition or after starting the engine.
The warning lights are at the following locations in the instrument cluster

damage to the vehicle.■
If you have to stop for technical reasons, then park the vehicle at a safe
distance from the traffic, switch off the engine and switch on the hazard
warning lights » page 57. Place the warning triangle at the prescribed
distance.
■
