General information
Breaking in
A new vehicle must be broken in for the first
1,000 mi les (1,500 km). Do not dr ive at speeds
that will exceed 2/3 of the maximum permitted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid full acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles
(1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into p lace with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initia l
break-in period, particularly when running a cold
engine . This will reduce eng ine wear and improve
the m ileage .
Do not drive at too low of an engine speed (RPM) .
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced.
Reducing the risk of vehicle damage
([) Note
When driving on poor roads, by curbs and on
steep ramps , make su re that low-hang ing
components such as the spoiler and exhaust
system do not come into contact with these
or they could be damaged. This especially ap­
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driv ing through water, for example
on flooded roads :
- The water must not be any higher than the bot­
tom of the vehicle body.
D riving
- Do not drive faster than walking speed.
A WARNING
After driv ing through water or mud, the effec­
tiveness of the brakes may be reduced due to moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes and restore the full braking ef­
fect .
(D Note
- Vehicle components such as the engine,
transmission, suspens ion or electrical sys-
tem can be severely damaged by driving
through water.
- Always switch the Start/Stop system" off
when driving through water¢
page 84.
(D Tips
-Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid driv ing through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
T he amount o f fuel consumpt ion, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an ant icipatory and economic driving
style, fuel consumption can be reduced by ap­ proximately 10-15%. The following tips will help
you conserve the environment and your money at the same time.
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a gear ..,.

Driving
engaged, for examp le when you notice that the
next traffic light is red . This produces an engine
braking effect, wh ich helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during decelera­
tion) .
Shift efficientl y
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari­
ly .
Press down on the acce lerator peda l slowly and
avoid "k ick -down".
Avoid full acceleration
You sho uld rarely t ravel a t the maximum vehicle
speed. High speeds cause a disp ropor tionately
h igh increase in fuel consumption, emissions and
traffic noise . Driving more slowly saves fue l.
Reduce idling time
The Start/Stop system* helps to reduce the id ling
time automatically. In vehicles wi tho ut the Start/
Stop system*, it is efficient to switch the engine
off when stopped at rai lroad crossings and long
red lights . Stopping the engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
I t takes a very long time in idle to wa rm the en ­
gine up to operating temperature . Wear and
emissions are especially high in the wa rm -up
phase. Therefore, yo u should begin driving im­
mediately after starting the engine. Avoid high
RPMs while do ing th is .
Have ma intenance performed regularly
By having maintenance performed regu larly on
your veh icle, you can help to reduce f uel con­
sumpt ion before yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long -term value but a l­
so impacts f uel consumption . A poorly main­
tained engine can lead to f uel consumpt ion that
is 10% higher tha n normal.
80
Avoid short trips
The eng ine and exh aust clean ing syste m mus t
r each their op tima l operating temperatu re to ef­
fectively reduce consumption and emissions.
A cold engine uses a d isp roportion ately high
amoun t of fue l. The e ngine re aches opera ting
temperat ure and cons umption norma lizes on ly
after approximate ly 2.S mi les ( 4 km).
Check the tire pressure
To save fue l, ma ke sure the t ires are always in­
flated to the corre ct press ure
~ page 343. The
f uel consumpt ion c an increase by S% if the p res­
s ur e is only 0 .S bar too low. Due to the inc reased
rol ling resistance, low tire pressures w ill also
l ead to greater tire wear and will affect driving
behavior.
Do not drive on winter tires year -round, as this
will consume up to 10% more f ue l.
Eliminate unnecessary weight
Since eve ry po und of ext ra weight increases f uel
consump tion, a quick inspect io n of the luggage
compartment may be wo rth it to avoid unneces ­
sary weight .
When not be ing used, a roof ra ck sho uld be re­
moved to decrease the w ind resis tance of the ve­
hicle . This will save yo u approx ima tely 12% fue l
at speeds from 62 -7S mph (100 -120 km/h) .
Save energy
The engine d rives the generator, which generates
electri city; the f uel consumpt ion also increases
with t he deman d for e lec tricity . T he refore, sw itch
electrica l eq uipment o ff when you no longe r
need it . Examples of eq uipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
CJ) Note
Do not leave engine idling unattended after
starting. If warning lights s hould come on to
i ndicate imprope r operation, they would go
unheeded. Extended idling also prod uces
h eat, which could result in overheating or
other damage to the vehicle or othe r proper­
ty .

Operating instructions
Trailer towing weights
The maximum permissible unbraked trailer
weight is 1,650 lbs (750 kg) .
The maximum permissible braked trailer weight
is:
- Q7 2.0: 5,500 lbs (2,500 kg)
- Q7 3 .0: 7,700 lbs (3,500 kg)
These specifications apply when driving on roads having an incline of less than 12% .
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maximum allowable or
slightly lower . You can get an approximation of
the tongue load with a bathroom scale or you can
measure the load at a trucking company or
weighing station.
The maximum permissible load on the ball hitch may not exceed:
- Q7 2.0: 550 lbs (250 kg)
- Q7 3 .0: 770 lbs (350 kg)
It is recommended to use the maximum permis­
sible load. Please also observe the information
¢page 343, ¢page 347.
Trailer load distribution
Be sure the load in the trailer is held securely in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.
in Messages on page 100.
Ball mount
The trailer hitch may only be used with suitable ball mount and ball. Installation of the hitch ball
must be carried out in accordance with the manu­
facturer's instructions .
Trailer towing
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the label <:!;>
page 343. Inflate trailer
tires to trailer and tire manufacturers' specifica­
tions.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle .
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
Setting drive select(air suspension)*
Make sure the vehicle is on a level surface before
hitching the trailer and before adjusting the
tongue weight. The driving mode must be in
Au­
to or Comfort ¢page 134, ¢ (D
If you would like to drive in the Dynamic driving
mode, then you must select this mode before
hitching the trailer and before adjusting the
tongue weight. Please note that your vehicle will
lower and the ground clearance is reduced.
If you have to drive through difficult road condi­
tions, you can raise the vehicle again after hitch­
ing the trailer or after adjusting the tongue
weight

Assistance systems
Electronic speed Limiter
Your v ehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum sp eed
of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­ ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
lim iter prevents your vehicle from going faster
than the t ire speed rating. For mo re information
<=> page 333.
If the engine control unit receives faulty vehicle
road speed s ignals , the Malfunction Indicator
L amp (MIL)
¢..ffi will illumina te . If this occurs,
con tact the nearest au thorized A ud i dealer for
assistance.
_& WARNING
Always observe the posted speed limits and
adjust you r speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the tires installed .
Speed warning system
Introduction
Applies to: vehicles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
-
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
A wa rning tone will sound as soon as you r speed
ex ceeds the s tored v alue s light ly. Th e indicato r
light also turns on in the instrument cluster dis ­
p lay
ct] (USA models)/ [SJ (Canada models) and
a message . The indicator light
(CJ / [SJ and the
message turn off if the speed falls back be low
the stored maximum speed.
Se tting a threshold is recommended if you would
like to be reminded when yo u reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gene r-
102
al speed limit or if there is a spec ified maximum
speed for winter tires.

:E Air suspension*
The air suspension* is an electronically-control­
l ed air suspens ion and damping sys tem . The ad­
justment depends on the driving mode selected, steer ing movements, the driver's braking and ac­
celeration, and as the road surface, vehicle speed
and load. The vehicle ground clearance depends
on the mode selected and the speed .
The ground clearance increases s ignificantly
when the vehicle is in the
Allroad mode . At
speeds from approximately 50 mph (80 km/h) to
75 mph (120 km/h), the ground clearance re­
duces in stages. When the speed decreases, the
ground clearance increases again automat ically .
The ground clearance is the lowest in
Dynamic
mode.
Steering
The power steering adapts. Ind irect steer ing that
moves easily as in
Comfort mode is especially
suited to long drives on highways. The
Dynamic
mode provides sporty, direct steering.
All-wheel steering*
All-wheel steer ing increases driving comfort by
providing addit ional steering ability at the rear
axle . Steer ing in the opposite d irection at low
speeds decreases the turning rad ius. Steering in
the same d irect io n at high speeds improves the
response time while increasing driving stability at
the same time .
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 152, the sport diffe rential dis­
tributes the dr iv ing power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the selected mode
from moderate
( Comfort ) to sporty (Dynamic ).
The goal is a high level of agility and ability to ac ­
celerate on curves . The vehicle is very responsive
to steering.
Adaptive cruise control (ACC)*
The behavior when accelerating can be adjusted
from comfortab le to sporty, depending on the
drive select mode. Adaptive cruise control also
Assistance systems
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
T he eng ine sound adapts to the current mode
and can be subtle to sporty .
(D Note
Applies to: vehicles wi th air suspensio n
-Make sure there is enough clearance above
and below the vehicle when parking. The
height of the ve hicle (gro und clearance) can
change once it is parked due to temperature
fluctuations, changes to the load conditions
and changes to the dr iving modes.
- When transporting the vehicle on a car car­
rier, train, ship or by other means, only tie
the vehicle down at the running surface of
the tires, which is the outer c ircumference.
Sec uring the vehicle at the axle compo­
nents, suspension struts o r towing eyes is
not permitted because the pressure in the
air suspens ion struts can change during
transport. The vehicle may not be secured
sufficiently if this happens.

All-wheel drive (quattro)
General informat ion
I n all whee l drive, the dr iv ing power is dis trib ut­
ed between all four whee ls when needed . This
happens automatically depending on your driving
behavior as we ll as the c urrent road cond it ions.
Also see ¢
page 148, Electronic stabili zation
control (ESC).
The all-whee l drive system distributes the driving
power va riably to the front and rear axle. It works
together with selective wheel torq ue control,
which act ivates when dr iv ing through curves
¢ page 148. With the sport d ifferent ial*, power
dist ribution to the rear wheels is variable and can
be adjusted using the drive se lect
¢ page 134.
The all wheel drive concept is designed for high
engine power . Your vehicle is except iona lly pow ­
erfu l and has excellent driving charac teristics

:E: ' Snow chains
If there are snow cha in laws, snow chains must
a lso be used on vehicles with a ll wheel drive

Replacing tires
For vehicles w ith all wheel dr ive, only whee ls w ith
the same ro lling circumference shou ld be used .
Avoid using tires w ith different tread depths
¢ page 340, New tires or wheels .
.&_ WARNING
-Also, in vehicles with all wheel drive, adapt
yo ur 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 isk 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 wheel dr ive vehi­
cl e. Do not be tempted to accelerate to a
high speed when the road is slippe ry, be­
ca use this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hyd roplane" if d riving at speeds that
are too high . Unlike front whee l drive
vehicles, the engine does not rev higher su d­
denly when the vehicle begins hyd roplaning .
For this reason, adapt your speed to the
road conditions to reduce the risk of an acc i­
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.
W hen a ve hicle w ith a convent ional energy sys­
tem is not driven for a long tim e, the vehicle bat ­
t ery is dra ined by equipment (fo r example, the
i mmobilizer). In certain circumstances, there
could may not be enoug h energy to start the en­
gine .
Intellig ent Technology
Your vehicle is equipped with an intell igent ener­
gy management system for dist ributing electrici ­
ty . Th is sign ificantly improves the start ing ability
and increases the vehicle battery life.
T he ene rgy management system Is made up of
battery diagnosi s, idling cu rrent management ,
and dynamic energy management .
Battery diagnosis
T he battery diagnos is determines the vehicle ba t­
te ry charge level. The sensors determine the bat­
te ry vo ltage, the batte ry cu rrent, and the battery
temperat ure. The cur rent charge level and the
performa nee of the vehicle battery a re deter ­
mined based on this.
Idling current management
T he idling cur rent management decreases the
energy used while parked . With the engine
switched off, it ma nages the energy distribution
to the d ifferent e lectr ica l components . Data from
the battery d iagnosis is taken into account for
th is.
Depending on the vehicle battery charge level,
electrical equ ipment is switched off one item af­
ter the other to prevent the vehicle battery from
dra ining and to ma intain the starting ab ility .
Dynamic energy manag ement
While driving, dynamic energy management dis ­
t ributes the appropr iate amo unt of energy to the
electrical eq uipment. It contro ls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to maintain an optimal vehicle battery charge
level.

:E: ' -The tire pressure must correspond to the
load. The tire pressure label lists the recom­
mended cold tire inflation pressures for the
vehicle at its maximum capacity weight and
the tires that were on your vehicle at the
time it was manufactured. For recommend­
ed tire pressures for normal load condi­
tions, please see chapter

Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .
Use the tie-downs to secure your cargo properly
c:> page 261, Loading the luggage compartment.
In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury. Items in the vehicle possess energy which
vary with vehicle speed and the weight of the
item . Vehicle speed is the most significant factor .
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 -lb
(4 .5 kg) object are about 20 times the normal
weight of the item . This means that the weight
of the item would suddenly be about
200 lbs . (90 kg). You can imagine the injuries
that a 200 lbs. (90 kg) item flying free ly through
the passenger compartment could cause in a col ­
lision like this.
A WARNING
Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard
braking or in a collision and cause serious per­
sonal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from shifting or flying forward as dan­
gerous missiles .
- When the rear seat backrest is folded down,
always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from flying forward as dangerous
missiles into the passenger compartment .

Driving safety
-Never attach a child safety seat tether strap
to a tie-down.
Reporting Safety Defects
Applicable to U.S.A.
If you believe that your vehicle
has a defect which could cause a
crash or could cause injury or
death, you should immediately in­
form the National Highway Traffic
Safety Administration (NHTSA) in
addition to notifying Audi of
America, Inc.
If NHTSA receives similar com­
plaints, it may open an investiga­
tion, and if it finds that a safety
defects exists in a group of
vehicles, it may order a recall and
remedy campaign. However,
NHTSA cannot become involved in
individual problems between you,
your dealer, or Audi of America,
Inc.
To contact the N HTSA, you may
either call:
Tel.:
1-888-327-4236 (TTY:

General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.
