Instruments and indicator lights
(+S °C), a snowflake symbol appears in front of
the temperature display.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed may
be slightly higher than the actual temperature
outside due to the heat radiating from the en
gine.
A WARNING
Do not assume the roads are free of ice based
on the outside temperature display . Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+S
0
()
and that ice can increase the risk of accidents .
@ Tips
You can change the measurement units, for
example for temperature or speed, in the
MMI.
Fuel level
The display @ q page 10, fig. 3 only works when
the ignition is switched on. When the display has reached the reserve mark, the bottom LED will
turn red and the
tj] indicator light turns on
q page 24. Th e bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level~
page 29, On-board comput
er display.
For the tank capacity in your vehicle , refer to the
Technical Data
qpoge 303.
(D Note
Never drive until the tank is completely emp
ty . The irregular supply of fuel that results
from that can cause engine misfires . Uncom
busted fuel will then enter the exhaust sys
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica
t or, an indicator light . will turn on when the
12
coolant temperature is too high q page 20. Re
fer to
q 0 .
The coolant temperature indicator @ q page 10,
fig. 3
only works when the ignition is switched
on. To prevent engine damage, please observe
the following notes about the temperature rang
es .
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem
perature yet. Avoid high engine speeds, full ac
ce lerating and heavy engine loads.
Normal range
The engine has reached its operating tempera
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions. The
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
T his is no cause for concern as long as the. in
dicator light in the instrument cluster does not
turn on.
Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high
q page 20 .
A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment . This increases the risk of
burns . Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area. Stop the engine and
allow it to cool before working in the engine
compartment. Always follow the informa
tion found in¢
page 236, Working in the
engine comportment.
([) Note
-In vehicles with a boost pressure indicator*,
this indicator replaces the temperature dis
play. To promote a long engine service life,
avoiding high engine speeds, full

Driv ing in city traffic -
Accelerate moderately and brake

- Intentionally take your foot off of
the gas peda l to allow for Lengthy
coast ing .
Driv ing on highways
-Reduce the vehicle speed by re-
and expressways leasing the accelerator pedal and
not by braking.
- Use the S selector lever position
and tiptronic mode sparing ly.
- Do not run the gasoline engine
while the vehicle is parked to warm
the engine.
- Use the rear window/exterior

-Park the vehicle in a garage over -

Vehicle behavior
The kinetic energy of the vehicle is used to
move the vehicle.
The gasoline engine turns
off automati -
cally and disengages when you release the
accelerator pedal comp letely. The veh icle
glides without being propelled .
The electric motor brakes the vehicle. By
doing this, a large amount of the kinetic
energy is recovered and may be stored in
the high-voltage battery in the form of
electric energy .
The kinetic ene rgy of the veh icle is used to
move the vehicle.
The gasoline engine turns

cally and disengages when yo u release the

g lid es without being p ropelled .
Fu el cons umption can be reduced by
coasting .
A sporty driv ing style increases fue l con-
sumpt ion.
The temperat ure of the gasoline eng ine
rises very s lowly and the fuel consump-
tion increases considerably .
This conserves the energy in the high-volt-
age battery so that it is availab le to run
the vehicle in electric mode.
This reduces exposure of the high-voltage
battery to cold temperatu res . The re-
quired temperature range for the high-
voltage battery will then be reached more
quickly after you start driving.
