CD Note
The needle in the tachometer @ Q page 10,
fig. 4 or¢ page 10, fig. 3 may only be in the
red area of the gauge for a short time or there
is a risk of engine damage. The location where
the red zone beg ins varies depending on the
eng ine .
@ For the sake of the environment
Upshifting early helps you to save fuel and re­
duces operating noise .
Fuel level
The display@¢ page 10, fig. 4 or ¢ page 10,
fig. 3 only functions when the ign ition is swi tch­
ed on . When the display has reached the reserve
mark, a red LED appe ars and the
rD indica to r
light t urns on ¢
page 28. The LED blinks red
when the f uel level is very low .
For the tank capacity in yo ur vehicle , refer to the
Te chnical Data
¢ page 38 2.
CD Note
Never d rive until the tank is comple tely emp­
t y. The irregular supp ly of fuel that resul ts
from that can ca use engine misfi res . U ncom­
bus ted fuel will the n enter the e xhaus t sys ­
tem . This can cause overheating and damage
to the cata lytic conve rter .

Trip odometer and odometer
The trip odometer shows the dis tance driven
s ince it was last reset. It can be used to measure
short d istances.
The trip odometer ca n be reset to zero by p ress­
i ng t he rese t button ®¢
page 10, fig. 4 or
¢page 10, fig. 3.
The odometer shows the total d istance that t he
vehicle has been drive n.
Malfunction indicator
If there is a malfunction in the instrument clus­
te r,
DEF will appear in the trip odome ter display .
Have the malfunction corrected as soon as possi­
ble.
Outside temperature display
If your vehicle i s sta tionary or if yo u are driv ing at
very low speeds, t he temperature d isplayed may
be slight ly higher than the actual temperatu re
outside due to the heat radiating from the en ­
gine .
At temperatures be low 41 °F (+S °C), a snowf lake
symbol appears in front of t he temperature dis­
play ¢.&. .
A WARNING
Do not assume the roads are free of ice based
on the outside tempe rature disp lay. Be aware
that t here may be ice on roads even when the
outside temp erature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents .

(D Tips
It may be necessary for the gasoline engine to
r u n longer for technical reasons, such as
when condensation accumu lates in the en­
gine. Driving exclusively in electric mode is
not possible in this phase.
Plug-in hybrid functions
Applies to: vehicles with plug-in hybrid drive
The funct ions descr ibed below act ivate automati­
cally depending on the driv ing sty le.
Full-throttle acceleration (boost)
The boost funct ion is act ivated by pressing the
accelerator pedal farther down (kick-down). The
vehicle is powered by both the gasoline engine
and the electric motor when in full accelerat io n.
Boost is only availab le for a sho rt time , because it
uses a large amou nt of energy. Ava ilability de­
pends on the high-voltage battery charge level.
Coasting
The gasoline engine switches off and disengages
at speeds up to approximate ly 112 mph
(180 km/h) if the accelerator pedal is not p ress-

Driving situations Conditions
e-tron
ed and the "D" position is selected. Driving con­
servative ly like this can reduce fuel consumption .
Energy recovery (recuperation)
When braking, t he e lectr ic moto r will act as a
generato r creat ing elect ric energy that is then
stored in the hig h-voltage battery. This also o c­
curs when the vehicle is coasting or driving down ­
hill .
If the brakes are applied early and evenly, the
electric motor w ill brake the vehicle @
¢
page 95, fig. 98. By doing this, a large amount
of the kinetic energy is recovered and may be
stored as electric energy in the high-voltage bat­
tery . The conventional brakes are also activated
when the brakes are pressed very hard.
The strength of recuperation can depend on the
following factors:
- If you are in tiptronic mode ¢
page 88. Or
- I f the sport dr iv ing mode "S" was se lected.
The energy recovery is shown in the energy flow
display in the instrument cluster display/Info­
ta inment system
