The combustion engine is operated on ly as need
ed . Gene rally, the combustion engine turns off
when the vehicle is stationary and the high vo lt
age battery powers the electrical vehicle sys
tems.
The purpose of automatica lly shutting the com
bustion engine off in hybrid drive mode is to save
fuel. All of the important vehicle systems, such
as steering, brakes and the A/C system, continue
to rema in active. In some cases, systems may re
qu ire the combustion eng ine to continue running
when the vehicle is stationary . When dr iving in
congested traffic for long periods of t ime, the
combustion engine will cycle on when the veh icle
is stat iona ry to keep the h igh voltage battery
charged.
Gliding
If the gas pedal is not pressed and the D posit ion
is selected, the combustion engine remains
turned off up to speeds of app roximately 99 mph
(160 km/h) . D riving conservat ively like th is can
reduce fuel c:on5umption .
Energy recovery (recuperation )
When braking, the electric motor will act as a
generator creating electr ic energy that is then
sto red in the high voltage battery. This also oc
curs when the ve hicle is coasting or dr iving down
hill. The combustion engine is automatica lly
turned off in this case.

The vehicle is braked with the electric motor by
applying early and even pressure to the brakes
and using short pedal movements~

fig. 110 @. By doing this, a large amount of the
kinetic energy is recovered and may be stored as
electric energy in the high voltage battery. Dur

so act ivated

The energy recovery is shown in the MMI d isplay

Automatic start of the combustion engine
Various operating conditions cause the combus
t ion eng ine to start automatically:
- The high vo ltage battery charge level is low.
- The temperatu re of the combustion engine is
low.
- The temperature of the catalytic converter is
low.
- The power output needed for the A/C system is
high.
- The vehicle speed is high .
- The vehicle acceleration is high .
- The incline is steep .
- High charge level for the high voltage battery
when coasting. In this case, the high voltage battery cannot absorb any more energy and so
the electric motor cannot slow down the veh i
cle . The combust ion engine turns on (engine
brake). In th is situation the high voltage bat
tery will show a Max charge.

Airbag syste m
The side airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col
lision . The airbag deploys only in side impacts
and only when the vehicle acceleration registered
by the control unit is high enough . If this rate is
below the reference value programmed into the
control unit, the s ide a irbags wi ll not be tr ig
gered, even tho ugh the car may be badly dam
aged as a result of the collision. It is not possible
to define an airbag triggering range that will cov
er every possible angle of impact, s ince the cir
cumstances will vary cons iderably between one
coll is ion and another. Important factors include,
for example, the nature (hard or soft) of the im pacting object, the ang le of impact, vehicle
speed , etc.
r::;, page 167, Important safety in
structions on the side airbag system .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas
senger in pos it io n in the event of a s ide collision
so that the side a irbags can provide protection .
The airbag system is
not a subst itute for your
safety belt. Rathe r, it is part of the overa ll occu
pant restraint system in your vehicle . Always re
member that the s ide airbag system can only
he lp to p rotect yo u if you are wea ring your safety
be lt and we aring it properly. This is ano ther rea
son why you should always wear your safety
be lts, not just because the law requires you to do
so
r::;, page 143, General information.
It is important to remember that whi le the sup
p lemental side a irbag system is des igned to re
duce the likelihood of serious injuries, other inju
ries , for example, swelling, bruising, and minor
abrasions can also be associated with deployed
side airbags . Remember too , side airbags will de
ploy o nly once and only in certain kinds of acci
dents -your safety belts are always there to offer
p rotection .
Veh icle damage, repa ir costs or even the lack of
veh icle damage are not necessarily an indication
of over -sensitive or failed airbag activation . In
some coll is ions, both front a nd side a irbags may
inflate. Remembe r too, that airbags will deploy
only once and only in ce rtain k inds of coll is ions -
166
your safety be lts are always there to offer protec
tion in those accidents in which a irbags are not
supposed to deploy or when they have already
deployed .
The si de airbag system will not d eploy:
- when t he ign it ion is tu rned off
- in side co llisions whe n the accele ration meas-
ured by the sensor is too low
- in front-end collis ions
- in rear-end collisions
- in rollovers .
In some types of accidents the front airbags, side curtain airbags and side airbags may be triggered
together .
A WARNING
--Safety belts and the airbag system will only
provide protect ion when occupants are in
the prope r seat ing pos ition
r::;, page 167.
- If the a irbag ind icator light<=> page 16
comes w hen the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer. It is possib le that
the airbag will inflate when i t is no t sup
posed to, or wi ll not inf late when it sho uld .
How supplemental side airbags work
Side airbags deploy instantly and can help re
duce the risk of upper torso injuries for occu
pants who are properly restrained.

Fuel and R efu eli ng
Gasoline additives
Applies to veh icles: w ith gaso li ne engine
A major concern among many auto manufactur
ers is carbon deposit build- up ca used by the type
of gasoline you use.
Although gasoline grades d iffer from one manu
facturer to another, they have certain things in
common. All gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake valves . Al
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas
oline. For more information on TOP TIER Deter
gent Gasoline, please go to the official website (www.toptiergas.com).
After an extended pe riod of using inadequate
fue ls, built-up carbon depos its can rob your en
gine of peak performance.
(D Note
- Damage or ma lfunction due to poor fue l
quality is not covered by the Audi New Vehi
cle Limited Warranty.
- Do not add aftermarket fuel additive prod
ucts to yo ur fuel tank.
Diesel fuel
Applies to veh icles: w ith d iese l e ngine
Always use ULSD (Ultra Low Su lfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM D97S.
Diese l fuel with concentrations of biodiesel high
er than S % such as 811,820 or 8100 are strictly prohibited.
Service station f uel pumps are labeled with the
correct fue l information for easy recognition by
the user.
If the diesel fuel pump is not labeled
ask the station operator what fuel is be ing dis
pensed before filling up your vehicle .
ULSD No . 2 may not be availab le outside the USA
and Canada . Be sure to check before traveling to
other countries .
214
ULSD No. 2 can become thicke r in very cold tem
peratures, and this can impair the engine's start
i ng and running. Depend ing on the season, gas
stations provide ULSD No. 2 that flows better in
cold temperatures so that you can continue oper
at ing your vehicle as usual.
(D Note
- Your vehicle's diese l eng ine was designed
so ley for use w ith ULSD No. 2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system and the engine. Such damage will no t be
c ove red by your New Vehicle Limited War
ranty .
-If you pu t any amo unt of inco rre ct fuel in
the fuel tank, do not start the engine u nder
any circumstances. Immed iate ly contact the
nearest authorized Audi dealer or author
ized Audi Serv ice Facility for ass istance .
These fuels contain substances that can se
verely damage the fuel system and the en gine if the engine is started .
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap .
If the power lock ing system shou ld fai l, you can
still open the flap manually -fo r detailed instruc
