All wheel drive (quattro)
App lies to vehicles : with all wheel drive
In all wheel drive, all four wheels are powered .
General information
In all whee l dr ive, the dr iv ing power is divide d be­
tween all four whee ls. Th is happens automat ic al­
l y depending on yo ur driv ing behavior as well as
the cur rent roa d conditions . Refer to r=>
page 188,

Winter tires
By using all whee l dr ive, your ve hicle has good
forward motion with sta ndard t ires in winter con­
dit ions . However, in winter we recommend usi ng
winter or all seaso n tires on a ll fou r wheels, be­
cause this will improve the braking eff ect.
Snow chains
If there are snow chain laws, snow chai ns m ust
also be used o n ve hicles with all wheel drive

Offroad vehicle?
Your Aud i is not an off road vehicle -there is not
enough ground clea rance . For this reason, avo id
difficu lt terrain .
A WARNING
-Also, in vehicles with all whee l dr ive, adapt
your dr iving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks, because t his increases the risk of an acci ­
dent .
- The brak ing ability of yo ur vehicle is lim ited
to the traction of the wheels . In this way, it
is not different from a two wh eel drive veh i­
cl e. Do not be tempted to ac celerate to a
high speed when t he ro ad is s lippery th is in­
cr eases the r is k of an accident .
- Note t hat on wet streets, t he front w heels

are too high. Unli ke front whee l drive
vehicles, the engi ne does not rev higher sud ­
den ly when the vehicle begins hydrop laning.
For this reaso n, pay attent ion to the r oad
condit ions regardless of your speed to re­
duce t he risk of an accident .

Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
~ Shut the engine off when you are not driving
the vehicle.
~ Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automatically reduced for
veh icles with the Start-Stop-System . It is effi­
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at railroad
crossings and long red lights. Turning the engine
off for just 30-40 seconds saves more fuel than is
burned by starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially high when
the engine is warm ing up. So you shou ld drive
away as soon as you start the engine and avoid
running at high rpms while the engine is still
warming up .
(D Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling a lso produces
heat, wh ich could resu lt in overheating or oth­
er damage to the vehicle or other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
~ Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an
Aud i dea ler helps to ensure that it runs properly
and economica lly. The condition of your vehicle
not only affects its safety and ability to hold its
value, it a lso affects fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load
and speed.
Driving and the environment
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile­
age has been driven.
You must drive your veh icle about 3,000 miles
(5,000 kilometers) before you can properly as ­
sess oil consumption .
T h is also applies to fuel consumption and engine
o ut put .
CD Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the em ission contro l system and
cou ld lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, sw itches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips .
~ Try to avoid dr iv ing short distances w ith a co ld
eng ine .
The engine and cata lytic converter have to reach
their optimal operating temperature to reduce
fuel consumpt ion and nox ious em issions effec­
t ively.
Just after starting, a co ld engine in a mid-size car
only achieves a fuel economy of 6-8 mi les per
gallon (30-40 l/100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km). After about
2.5 miles (4 km), the eng ine is
at its proper operating temperature and fuel
economy has reached a norma l level. So you can
see that you should avoid short trips whenever
poss ible. .,.

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, p lease remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trai ler, you must ac­
tivate the trailer operat ion mode
c::> page 201, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a
technically
sound
location. Use only a trailer hitch with a re­
movable ball mount. Always check with the trail­
e r hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact-absorbing
bumper system. No modifications should be
made to the vehicle exhaust and brake systems.
From time to time, check that all hitch mounting
bolts remain securely fastened .
When you are not towing a trailer,
remove the
trailer hitch ball mount. This prevents the hitch
from causing damage should your vehicle be
struck from behind
c::> &, .
Trailer mode
Trailer brakes
If your trailer is equipped with a brak ing system,
check to be sure that it conforms to all regula­
tions.
T he trailer hydraulic brake system must not be di­
rect ly connected to the vehicle's hydraulic b rake
system.
Safety chains
Always use safety chains between your veh icle
and the tra iler.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check with your Aud i dealer for correct wiring,
switches and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision to the rear .
A WARNING
--
After removing the trailer hitch, do not store
i t in your vehicle. In case of sudden braking,
the hitch could fly forward and injure you or
your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held securely in
place to prevent it from sh ifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer c::> &.
in Driving instructions on page 203 .
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 . .,..
201

Trailer mode
Tire pressure
When tow ing a trailer, inflate the tires of your ve­
hicle to the cold tire pressure listed under " Full
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
Check to make sure both vehicle and trailer lights
are working properly .
Safety chains
Be sure trailer safety cha ins are p roperly connect­
ed from the trailer to the hitch on the vehicle.
L eave 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 trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make su re the vehicle is on a level su rface before
h itching up the trailer and before adjusting the
tongue weight . The vehicle must be in
auto or
comfort driving mode and not raised
r::!> page 101, r::!> 0.
Make sure that the vehicle is lowered. In Info­
tainment, select:
ICARI function button > Lower
control button.
If you must drive under poor road conditions, you
can raise the vehicle
after coupling the traile r or
after adjusting the tongue weight c::!> page 103 .
(D Note
-Changes in temperature or load can affect
the height of the vehicle.
- Always select
auto or comfort mode. Other­
wise, the tongue load specified for your ve­
hicle will no longer be applicable.

· Driving instructions
Driving with a trailer always requires extra care
and consideration .
To obtain the best possible handling of vehicle
and trailer, please note the follow ing:
.,. Do not tow a loaded trailer when your car itself
is not loaded .
.,. Be especially carefu l when passing other
vehicles.
.,. Observe speed lim its .
.,. Do not drive at the maximum permissib le
speed.
.,. Always app ly brakes early .
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car results
i n a h ighly unstab le distribution of weight. If th is
cannot be avoided, dr ive at very low speeds only
to avoid the risk of losing steer ing control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, w hile
k eep ing the traile r as light as possible under the
circumstances. Whenever possible, transfer
some ca rgo to the luggage compartment of the
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to contro l the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind cond itions are unfavorab le -particular ly when
going downh ill.
Red uce vehicle speed
immediately if the trailer
shows the slightest sign of swaying .
Do not try
to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds for
vehicles towing trai lers are lower than for regular
vehicles.
Always apply brakes early. When driving dow n­
hill, shift i nto a lower gear to use the engine

braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Air suspension*
When driving with a trailer, activate the trailer
mode of the air suspension. Switch the air sus­
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving. Select in the MMI:
ICARI function button > (Car)* systems control
button>
Vehicle settings> Air susp.: towing>
On.
Coolant temperature
The coolant temperature gauge c::> page 10 must
be observed carefully. The coolant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds . Reduce your speed
immediately if the LEDs in the top part of the dis­
play turn on .
For more information about indicator lights, re­
fer to.
c::> page 15.
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 mode notes
Important to know
-
Your vehicle handles differently when towing a trailer because of the additional weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic . Keep practicing until you have be­
come completely familiar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires practice. Back­
ing up with a trailer generally requires steering
Trailer mode
action opposite to that when backing up your ve­
hicle 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 would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- If you tow a trailer, your Audi may require
more frequent maintenance due to the ex­
tra load
c::> page 2 7 4.
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:
" Apply the foot brake.
" Have someone place chocks under both the ve­
hicle and the trailer wheels.
"With chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
"Turn the wheels towards the curb.
... Apply the parking brake.
"Select the P selector lever position.
When restarting after parking:
"Apply the foot brake.
"Start the engine.
"Select the D/S selector lever position.
"Release the parking brake and slowly pull out
and away from the wheel chocks.
"Stop and have someone retrieve the wheel
chocks .

Care and cleaning
- To reduce the risk of cuts, protect yourse lf
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice i n the winter. The brakes
must be d ried first w ith a few careful bra ke
applications.
(D Note
- If you wash the vehicle in an automatic car
wash, you must retract the rear spoiler if
necessary, and fold the exter ior mirrors in to
r educe the ris k of damage. Power folding
ex ter ior mirrors* must on ly be folded in and
out using the power folding function.
- To prevent pa int damage, do not wash the
vehicle in di re ct s unlight.
- To reduce the risk of damage to the s urface,
do not use i nsec t removing sponges, kitche n
sponges or similar ite ms. - Matte finish painted vehicle components:
-To reduce the risk of damage to the sur-
face, do not use polish ing agents or hard
wax.
- Never use protective wax.
It can destroy
the matte finish effect.
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith matte
finish paint. The pa int co uld be damaged
when the stickers o r mag nets are re­
moved.
@ For the sake of the environment
Only wash t he ve hicle i n facilities spec ially de­
signed for that purpose. Th is w ill re duce the

Checking and F ill in g
Battery
General information
Under no rmal operating conditions, the battery
in your Audi does not need any ma intenance.
W ith
high outside temperatu res or long daily
d rives we recommend that you have the electro­
lyte level checked by a service facility . The elec­
trolyte level should a lso be checked each time
the battery is charged ¢
page 230.
Have the bat tery checked when you take yo ur ve­
hicle in for service . You are we ll advised to re­
p lace a battery that is o lder than 5 years .
W ith certa in types of airbag deploymen t, the bat­
tery is disconnected from the vehicle electrica l
system for safety reasons ¢
.&. in Repair, core
and disposal of the airbags on page 158.
Disconn ecting the battery t erminal s
Some veh icle funct ions (power window regula­
tors, for examp le) are lost if the battery termi ­
na ls are disconnected. These functions have to be
re learned after the battery terminals are con­
nected aga in. To prevent this, the battery shou ld
only be disconnected from the vehicle electrical
system when absolutely necessary for repairs.
Vehicl es not driven fo r long period s
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca­ pability over a longer period¢
page 194. Some
of the convenience funct ions may not operate,
such as the inter ior lights or power seat adjust­
ment. The convenience functions will be ava ilab le
again whe n you swit ch on the igni tion and sta rt
the engine.
Winte r operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is because
mo re power is also consumed w hile starting, and
the head lights, rear w indow defogger, etc ., are
used more often.
Avoid unnecessary power consumption, part icu­
larly in city traffic or when traveling only short
