- Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine running while in gear. If you must leave
your veh icle when the engine is running,
set the parking brake and move these­
lector lever to the P position .
- Power is still transferred to the wheels
when the engine is runn ing at idle. To
p revent the vehicle from "c reeping", you
must keep you r foot on the brake when
the engine is running and the selector lever is in the D, So r R position or "tip­
tronic" mode is selected .

134 Safety belts
Important safety instructions about
safety belts
Safety belts must always be correctly posi­
tioned across the strongest bones of your
body.
,.. Always wear safety belts as illustrated and
described in this chapter.
,.. Make sure that your safety belts are always
ready for use and are not damaged.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death. Safety belts can
work only when used correctly .
- Always fasten your safety belts correctly
before driving
off and make sure all pas­
sengers are correctly restrained.
- For maximum protection, safety belts must always be positioned properly on
the body .
- Never strap more than one person , in­
cluding small children, into any belt.
- Never place a safety belt over a child sit­ ting on your lap.
- Always keep feet in the footwell in front
of the seat while the vehicle is being driv­
en .
- Never let any person ride with their feet on the instrument panel or sticking out
the window or on the seat.
- Never remove a safety belt while the ve­
hicle is moving. Doing so will increase
your risk of be ing injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable
objects in or on your clothing, such as
eye glasses, pens, keys, etc., as these
may cause injury.
- Never allow safety belts to become dam­
aged by being caught in door or seat
hardware .
- Do not wear the shoulder pa rt of the belt
under your arm or otherwise out of pos i­
tion . -
Several layers of heavy clothing may in­
terfere with correct positioning of belts
and reduce the overall effectiveness of
the system .
- Always keep belt buckles free of anything
that may prevent the buckle from latch­
ing securely .
- Never use comfort clips or devices that
create slack in the shoulder belt . Howev­
er, special clips may be required for the
proper use of some child restraint sys­
tems .
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an
accident. Inspect belts regularly .
If web­
bing, bindings, buck les, or retractors are
damaged, have belts replaced by an au ­
thorized Audi dealer or qualified work­
shop.
- Safety belts that have been worn and
loaded in an accident must be replaced
with the correct replacement safety belt
by an authorized Audi dealer . Replace­
ment may be necessary even if damage
cannot be clearly seen . Anchorages that
were loaded must also be inspected.
- Never remove, modify, disassemble, or
try to repair the safety belts yourself.
- Always keep the belts clean. Dirty belts
may not work properly and can impair
the function of the inert ia reel

""Insert the tongue into the correct buckle of
your seat until you hear it latch securely
c::>fig. 117.
.., Pull on the belt to make sure that it is se-
curely latched in the buckle.
Automatic safety belt retractors
Every safety belt is equipped with an automat­
ic belt retractor on the shoulder belt . This fea­
ture locks the belt when the belt is pulled out
fast, during hard braking and in an accident.
The belt may also lock when you drive up or
down a steep hill or through a sharp curve. During normal driving the belt lets you move
freely.
Safety belt pretensioners
The safety belts are equipped with a belt pre­
tensioner that helps to tighten the safety belt
and remove slack when the pretensioner is ac­
tivated
c::> poge 137. The function of the pre­
tensioner is monitored by a warning light
c::> page 21.
Switchable locking feature
Every safety belt except the one on the driver
seat is equipped with a switchable locking fea­
ture that
must be used when the safety belt is
used to attach a child seat. Be sure to read the important information about this feature
c::> page 177 .
A WARNING
Improperly positioned safety belts can
cause serious injury in an accident
c::> page 135, Safety belt position.
-Safety belts offer optimum protection
only when the seatback is upright and
Safety belts 135
belts are properly positioned on the
body.
- Always make sure that the rear seat
backrest to which the center rear safety
belt* is attached is securely latched
whenever the rear center safety belt is
being used. If the backrest is not secure­
ly latched, the passenger will move for­
ward with the backrest during sudden
braking, in a sudden maneuver and espe­
cially in a crash .
- Never attach the safety belt to the buck­
le for another seat . Attaching the belt to
the wrong buckle will reduce safety belt
effectiveness and can cause serious per­
sonal injury.
- A passenger who is not properly restrain­
ed can be seriously injured by the safety
belt itself when it moves from the stron­
ger parts of the body into critical areas
like the abdomen.
- Always lock the convertible locking re­
tractor when you are securing a child seat in the vehicle

Your vehicle is equipped w ith an intelligent
energy management system for distrib uting
e lectricity. This sign ificantly improves the
start ing ability and increases the battery life.
The energy management system Is made up
of
battery diagnosis , idling current manage­
ment
and dynamic ene rgy man agement.
Battery diagnosis
The b attery diagnos is determines the ba tte ry
cha rge leve l. The sensors de termine the bat ­
tery vo ltage, the battery c urrent , and the bat ­
tery temperature . The c urrent charge level
and the performance of the battery are deter­
mined based on th is.
Idling current management
The idling current ma nagement decreases the
ene rgy used whi le par ked . W it h the engine
switche d off, it ma nages the ene rgy distribu ­
tion to the d ifferent e lectr ica l components.
Date from battery d iagnosis is taken into ac­
count for th is .
D epending on t he battery charge level, elec­
tr ica l equipment is sw itched off one item after
the ot her, to prevent the battery from dra in­
i n g a nd to retain the starting abil ity.
Dynamic energy management
W hile dr iving, dynamic energy management
d istributes the approp riate amount of energy
to the electrical equipment. It contro ls the
battery c harge level so that more energy is
n ot used the n is being generated in o rder to
main tain an opt imal batte ry charge level.
{!) Tips
- Energy management cannot overcome
the laws of physics . Note that the charge
l eve l and length of the battery life are
li mi ted.
- Wh en the star ting ability is endangered,
the (•) indica to r li ght turns on
9page20.
Smart Technolog y 191
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is placed o n the batte ry when
driv ing s hort d ista nces, in traffic, and at cold
times of the year . A lot of e ne rgy is used but
li ttle is generated .
It is also cr it ica l when the
engine is not r unning but electr ical eq uip­
ment is switc hed on. In this case, e nergy is
u sed but none is gener ated.
In si tuat ions like this , energy management
will active ly r egu lated t he di st ribution of e n­
ergy.
Long periods without use
If you do not d rive your vehicle for several
days or weeks, elect rical eq uipment is gradu­
a lly scaled back or sw itched off. This reduc es
energy u se and en sures the ve hicl e w ill be
a ble to s tart aft er long per iod s of ti me . S ome
co nve nience fun ctions such as ope ning wi th
the remote con tro l key may not be available.
T hese convenience functions
will be ava ila bl e
again once you switch t he ignit io n on and
start the eng ine.
With the engine switched off
F o r example, if you listen to the r adio w hen
th e engine is swi tc h ed off, the bat tery will
drain .
If the st arting ability is en dangere d due to the
energy cons umption, an error message ap­
p ears in vehicles wi th a driver informat ion sys ­
