Driving
Under certain circumstances, (such as driving in
the mountains or towing a trailer), it may be use
ful to switch temporarily to the manual shift pro gram in order to manually adapt the gear to the
driving conditions
c::> page 71.
On inclines, activate the parking brake first and
then move the selector lever to the P position
c::> page 65. This prevents the locking mechanism
from being loaded too heavily and will make it
easier to move the selector lever out of the P po
sition .
_& WARNING
-The vehicle can also roll when the engine is
stopped.
- Unintended vehicle movement can cause se
rious injury.
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, ac
tivate the parking brake and move the selec
tor lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre
vent the vehicle from "creeping", you must
keep your foot on the brake when the en
gine is running and the selector lever is in D/
Sor R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is running .
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptron ic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re
duces braking performance, increases brak
ing distance or causes complete failure of
the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
70
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati
cally when it becomes too hot from the
overload. An indicator lamp . illuminates
and a driver message appears
c::> page 72
when the clutch is overloaded.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure these
lector lever has securely engaged and is
locked in P with the parking brake set
c::> page 159. Otherwise, any increase in en
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac
celerator pedal while a driving gear is se
lected. This can cause the automatic trans
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when th@ engine
is stopped while the selector lever is in the
N position will damage the automatic trans
mission, because it is not lubricated under
those circumstances
c::> page 211, Towing
with a tow truck.
- The transmission can overheat and be dam
aged under certain driving and traffic condi
tions such as frequent starts, creeping for a
long time, or stop-and-go traffic. If the.
indicator light turns on, stop the vehicle at
the next opportunity and let the transmis
sion cool down

Hill descent control
The hill descent control system assists the driver
when driving down hills.
Hill descent control is activated when the selec
tor lever is in the D or S position and you press
the brake pedal. The transmission automatically
selects a gear that is suitable for the hill. Hill de
scent control tries to maintain the speed ach- ieved at the time of braking, within physical and ..,.

Trailer towing
Sp eed
The higher the speed, the more d ifficult it be
comes for the driver to contro l the rig. Do not
dr ive at the maximum permissible speed. Reduce
your speed even more if load, w eather or wind
conditions are unfavorable -particularly when
going downhill.
Red uce vehicle speed
immediatel y if the trai le r
shows the s lightest sign of swaying .
Do not try
to stop the swayin g by ac cele rating.
Observe speed limits . In some areas, speeds for
vehicles towing trailers are lower than for reg ular
ve hicles.
A lways apply b rakes early . When dr iving down
hi ll, shi ft into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes a lone can cause them to overheat and fail.
Coolant temperature
The coolant temperatu re gauge ¢ page 8 must
be observed ca refully . If the needle moves close
to the upper end of the scale, reduce speed im
mediately and/or turn off the air conditioner .
I f t he coolan t temperature warn ing light i n the
instr ument cluster s tarts flashing ., pull off
the road, stop and let the engine
idle for about
two minutes to prevent heat bu ild-up .
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci
dent . Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi .
Trailer towing
information
Important to know
Your veh icle hand les different ly when tow ing a
tra iler because of the additional weight and dif
fe rent weight d istr ibut ion . Safety, performance
and economy w ill great ly depend on how careful
ly you load you r trailer and operate your rig .
76
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic . Keep pract icing unt il yo u h ave be
come comp lete ly familiar w ith the way your vehi
cle-tra iler combination behaves and responds.
Backing up is difficult and requires practice .
Backing up w ith a trailer generally req uires steer
i ng action opposite to that when backing up your
vehicle without a trailer.
Maintain a greater distance between your vehicle
and the one in front of you . You will need more
room to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When passing, remember that you cannot accel erate as fast as you normally wou ld because of
the added load. Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again.
Avo id jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri
od of your veh icle.
- If you tow a trai ler, your Audi may requi re
more frequent maintenance due to the ex
tra load
¢ page 218.
' Parking on a slope
Do not park on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
.,. App ly the foot bra ke .
.,. Have someone place cho cks under bot h the ve
hicle and the trailer wheels .
.,. With choc ks in place, slowly release the brakes
until the wheel chocks absorb the load.
.,. Turn the wheels towards the curb .
.,. App ly the parking brake .
.,. Move the selector lever to P .
When restarting after parking :
.,. App ly the foot brake .
.,. Start the eng ine .
.,. Move the se lector lever to D/S.

Electronic Stabilization
Control (ESC)
Description
Elect ronic Stabilization Control (ESC) suppo rts
driver safety.
It red uces the risk of slipping and
improves dr iving stability. ESC detects crit ica l sit
uations such as the veh icle oversteering and un
dersteering or the wheels are sp inning. The vehi
cle is stabilized by app lying the brakes or reduc
ing engine torque. When ESC engages, the
G1 i n
d icator light blinks in the inst rument cluste r.
The fo llow ing systems are integrated in the ESC:
Anti -lock b raking system (ABS)
ABS prevents the whee ls from loc king when brak
i n g . The vehicle can sti ll be steered even d uring
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assi st sy stem
The brake assist system can dec rease braking dis
tance. It increases brak ing power when the driver
presses the brake pedal quick ly in emergency sit
uations . You must press and hold the brake pedal
until the dangerous situat io n is over .
Anti- s lip regulation (ASR )
ASR reduces eng ine power when the drive w heels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler
ate and dr ive up h ills .
Electron ic differential lock (EDL)
The ED L bra kes wheels that a re spinning and
transfers the drive power to the other drive
wheel or wheels if the ve hicle is equipped with a ll
wheel drive*) . This funct ion is not ava ilable at
h igher speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over heating. The vehicle is still work ing correctly. EDL
92
will switch on again au tomatically when condi
tions have returned to normal.
Steering recommendation
The ESC he lps to s tabili ze the vehicle by cha ng ing
t h e s teer ing torque .
Selective wheel torque control
Selective wheel to rque cont rol is used when d riv
i ng o n curves . The front whee l on the inside of
t h e curve or both wheels on the i nside of th e
cu rve are braked se lective ly as needed. This al
l ows mo re pre cise driving in curves .
Automatic post -collision braking system
The "automat ic post -coll is io n braking system"
can help to reduce the risk of sl iding and of addi
tiona l co llisions after an acc ident. If the a irbag
c ontro l modu le detects a collision above a cert ain
vehicle speed, the veh icle is braked by the ESC.
The veh icle does n ot brake automatically if:
- the drive r presses the accelerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle elect ri
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. This is es pec ially impo rtan t
on sl ippery or wet roads. If the systems be
gi n a cting to stabili ze yo ur vehicle, you
s hould immedi ately alte r your speed to
match the road and tra ffic conditions . Do
not let t he in creased safety provi ded tempt
you into taking risks . This could increase
your r is k of a coll is ion.
- Please note the r is k of a coll is ion increases
when dr iv ing fast, especially th rough c urves
and on slippery or wet roa ds, and when dr iv
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre
ve nt co llisions - there is st ill a risk of acci
dents!

The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Dr iving in deep snow or on loose ground
- Driving on rough terrain when much of the car's
weight is lifted off the wheels (axle articula

Hill descent assist
Applies to: vehicles with hill hold assist
Hill descent assist makes it possible to drive
down a hill at a constant speed.
Fig . 100 Center console: hill descent assist button
.,. To switch the hill descent assist on, press the
~ button in the center console c:> fig. 100. The
LED in the button turns on.
.,. Press the button again to switch it off. The LED
in the button turns off.
Hill descent assist brakes all four wheels auto
matically in order to limit speed when driving ei
ther forward or reverse on hills with a grade up to
approx imately 50%.
When hill descent assist is on, the speed your ve hicle was traveling when it entered the hill is
maintained. It is only possible to switch on the
assist when driving slower than 37 mph (60 km/
h). The assist occurs br iefly after start ing to drive
up to approximately 19 mph (30 km/h). The driv
er can increase or decrease the vehicle speed
94
within these limits by pressing the accelerator or
brake peda l.
However, there must be enough tract ion. Hill de
scent assist
cannot function as expec ted, if fo r
example the hill is icy or if the surface is loose
c:>,& .
Active assistance at a specific speed up to about
19 mph (30 km/h) is shown in the instrument
cluster through a blinking indicator light •. The
indicator light shines continuously when in the
ready mode.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h). The system is
then in ready-mode . This is indicated by the LED
i n the button turning on. The system automat i
ca lly switched off when you drive faster than 37
mph (60 km/h) . The LED will also turn off in this
scenario.
Hill descent assist is automatically activated un
der the following conditions:
- the LED in the button turns on,
- the vehicle speed is lower than 19 mph (30 km/
h),
- the incline angle is at least around 10%.
_&. WARNING
-Always adapt your speed to the weather,
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident .
-
-The hill descent ass ist system cannot over
come the laws of physics. Your driving style
must always be adapted to the current road
and traffic conditions.
- Hill descent ass ist may not be ab le to hold
your vehicle at a constant speed under all
conditions while dr iv ing on a hill (for exam
ple if ground u nder the vehicle is loose).

All wheel drive (quattro)
A ppl ies to: ve hicles wit h all wheel drive
In oil wheel drive, oil four wheels ore powered.
General info rmation
I n all wheel drive, t he driving power is divided be
tween all four wheels . This happens automatical
ly depending on your driving behavior as well as
the current road conditions. Also see
¢ page 92.
The a ll wheel d rive concept is designed for h igh
engine powe r. Your vehicle is exceptionally pow
erful and has excellent driving characteristics both under norma l driving conditions and on
snow and ice. Always read and fo llow safety pre
cautions ¢.&. .
Winter t ires
By using all wheel drive, yo ur vehicle has good
forward motion with standard tires in w inter con
ditions. However, we recommend using winter or
all season tires on
all four whee ls in the winter,
because this will improve the
broking effect.
Snow cha in s
If there are snow chain laws, snow chains must
a lso be used on vehicles with a ll wheel drive
¢ page 186, Snow chains.
Replacing t ires
F or vehicles w ith all wheel dr ive, only wheels w ith
the same ro lling circumference shou ld be used .
Avoid using tires with different tread depths
¢ page 178, New tires or wheels .
A WARNING
-Also, in vehicles with a ll wheel drive, adapt
your dr iv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into tak ing risks,
because th is increases the r is k of an acci
dent.
- The braking ability of your veh icle is limited
to the tract ion of the wheels . In this way, it
is not diffe rent from a two whee l dr ive vehi
cl e. Do not be tempted to accelerate to a
high speed when the road is slippe ry, be
cause this increases the risk of an accident .
Intellig ent Technology
- Note that on wet streets, the front wheels
can "hydrop lane" if dr iv ing at speeds that
are too high . Un like front wheel drive
veh icles, the engine does not rev higher sud
denly when the vehicle begins hydroplan ing .
For this reason, adapt yo ur speed to the
road conditions to red uce the risk of an acci
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys
tem is not driven for a long time , the vehicle bat
tery is drained by equipment (for example, the
immobilizer). In certa in circumstances, there
could may not be enough energy to start the en
gine.
Yo ur vehicle is equipped with an intel ligent ener
gy management system for distributing electrici
ty . Th is sign ificantly improves the start ing ability
and increases the vehicle battery life .
The energy management system Is made up of
battery diagnosis , idling current manag em en t,
and dynamic energy manag ement .
Battery diagn osis
The battery diagnosis determines the vehicle bat
tery charge level. The sensors determine the bat
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery a re deter
mined based on this.
Idling current management
The idling current management decreases the energy used while parked. With the engine
switched off, it manages the energy dis tribution
to the d ifferent e lectr ica l components. Data from
the battery d iagnosis is taken into account for
t hi s.

Intelligent Technology
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability.
Dynamic energy manag ement
W hile driving, dynamic energy management d is
trib utes the appropriate amount of energy to the
e lectrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount be ing generated in or
der to mainta in a n optima l vehicle battery charge
level.
(D Tips
- Ene rgy management cannot ove rcome the
l aws of physics . Note that the charge level
and length of the vehicle battery life a re
l imi ted.
- When the starting ability is endangered, the
(•) indicator light turns on

What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when dr iv ing short d ista nces, dur ing c ity dr iving,
and at cold times of the year . A lot of energy is
used but little is ge nerated.
It is a lso critical
when the engine is not runn ing but e lectr ica l
eq uipment is switc hed o n. In this case, energy is
used bu t none is ge ne ra te d.
In s ituations like this, energy manageme nt will
actively regu late the d istribution of ene rgy .
Long periods without use
I f yo u do not drive your vehicle for seve ral days or
weeks, electrical equipment is gradually scaled
back or switched off . This red uces energy use and
ensu res the veh icle w ill be able to star t afte r long
pe riods of time . Some convenience functions ,
such as inte rior lighting or powe r seat adjust
men t, may not be available unde r certa in ci rcum
s tances. These co nvenience functions will be
ava ilab le again once you switch the ign ition on
and start the engine .

With the engine switched off
The vehicle b attery wi ll dr ain if you use Info tain
ment func tions such as lis teni ng to the radio
while the engine is switched off.
The veh icle's abili ty to s ta rt may be impa ired by
the e nergy use, a message will appe ar i n t he I n
fota inment system display.
The message indicates that the system wi ll
swi tch off autom atically soon .
If you would lik e
to co ntin ue usi ng the func tio ns , you mus t start
t h e engine.
With the engine running
Althoug h electrica l energy is gene rated w hile
driv ing, the veh icle ba tte ry can dra in. This can
happe n if li tt le ene rgy i s generate d but much is
u sed, and the ch arge level of the vehi cle b attery
i s not optimal.
To resto re t he ba lan ce of energy, co mponents
t h at req uire large amo unts of energy a re tempo
ra rily sc aled b ack or sw itche d off. Heat ing sys
tems in partic ular re quire a great deal of energy .
If you notice, for example, that the seat heating*
or r ear window defogger is not work ing, then it
has been tempora rily reduced or switched off.
These systems are avai lab le aga in as soon as t he
energy supply has bee n restored .
In ad dition, yo u may notice that the idle speed
has slightly increased. That is normal and no
cause for concern. By increasing the idling speed,
the addit ional required energy will be ge nerated
and the veh icle battery w ill be charged .
