Trailer towing Driving with a trailer
General information
Your veh icle is primar ily intended for transport­
ing people and luggage. However, if you dr ive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg­
u lations.
Driving with a trailer affects the vehicle 's fuel
consumption, performance and wear. It also re­
quires highe r concentration from the driver.
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
hitch mount and ball hitch. The trailer hitch must
be perm itted for the vehicle, the trailer and the
permitted total weight of the trailer being
pu lled. Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If the tra iler has its own brake system, then fol­
l ow the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Trailer towing
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The coo ling sys­
tem must be designed for additiona l load and
contain enough coo lant
i::> @ .
@ Note
Longer inclines cannot be driven without a
suitab le cooling system, especia lly if t he out­
side temperatures are high . otherwise, this
increases the risk of engine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribut ion can negatively
impact vehicle handling.
- Store objects preferably in the vehicle luggage
compartment . The vehicle should always carry
the heaviest poss ible load and the trailer
should have the lightest possible load.
- Distribute the load in the trailer so that the
heavy objects are as close to the axle as poss i­
b le.
- Secure objects from sl iding out of place .
- Ut ilize the maximum permitted tongue weight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure sticker
c::>page 211.
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom­ mendat ion .
Winter tires should be mounted on the vehicle and on the trailer during winter temperatures.
Outside mirrors
If you cannot see the tra ffic behind the trailer
with the standard exterior mirrors, then you
81

Trail er to wing
must attach additiona l exterior mirrors . Adjust
them so you have a sufficient visibility behind
you .
Exterior lighting
Follow the lega l regulat ions regard ing the light ­
ing eq uipment on your trailer . Conta ct an author ­
ized Audi dealer or authorized Audi Service Facili­
ty for more information.
Before start ing to drive, check a ll l ight ing equip­
men t on the hitc hed trailer.
The headlig ht range contro l adjusts automatical­
ly to the light range of the headl ights.
Safe ty chain s
Make su re the safety chains are correctly applied
when pulling a trailer . The chains should hang
enough so t hat the trailer can dr ive around
curves. However, they must not touch the
g round .
Air su spension
Applies to: vehicles with air suspension
The air suspension must be at the standard vehi­
cle height before you set the tongue weight on
the trailer a nd h itch the trailer ¢@ ,
¢page 106,
Raising/lowering the vehicle .
For ve hicles w ith a factory-installed tra iler hitch,
the air suspension trailer mode will automat ically
sw itch on if you connect the trailer cable to the
socket.
F or ve hicles w ith a retro fitted trailer hitch, you
must switch on the air suspension trailer mode
manually . Select in the Infota inment system:
ICARI function button > ( Car )* s yste m s contro l
button
> V ehicle setting s > Air su spen sion : trail ­
e r > On .
Switch it off again after tow ing a tra ile r.
You can also switch off tra iler mode ma nually
while driving , for example, when using a bicycle
rac k system .
If you have to drive through difficult road condi­
tions , you can raise the vehicle aga in after hitch­
ing the t rai ler or after adjust ing the tongue
weight .
82
@ Note
Applies to: vehicles with air suspension
-Changes i n temperature or load can affect
the height of the vehicle .
- Set the air suspension to the standard veh i­
cle he ight, otherwise the applicable tongue
we ight no longer appl ies to your veh icle .
(D Tips
-Use chocks when park ing on inclines if the
trai ler is loaded.
- We recommend also hav ing the vehicle in­
spected between the inspection intervals if
you are towing a trailer frequently .
- Avoid driv ing with a trai ler dur ing the veh i­
cle break-in per iod.
Driving with a trailer
Driving with a trailer requires extra caution.
Sp eed
Adhere to t he lega l speed lim its . Fo llow the legal
regu lat ions
sp ecific to the country.
As the speed increases, the dr iv ing stab il ity of
t h e tra ile r decreases. Therefore you should not
exceed the max imum lega l speed lim it w hen
t h ere are unfavorab le road, weather and/or wind
conditions. This especia lly applies when driving
downh ill.
Yo u m ust always red uce your speed as soon as
you notice even the slightest swinging motion o f
the trai ler . Never try to "straight en out" the trai l­
er by acce lerating.
The we ight d istr ibution is very poor if the vehicle
is empty and the trai ler is loaded. However if you
must drive under these circumstances, then drive
especially slowly .
Brakes
B rake in a time ly manner. Downs hift befo re dr iv ­
i ng down hill so that the engine can assist with
braking ¢&. .
When using a trailer w it h over run bra kes, fi rst
bra ke gently t hen q uick ly. This red uces the r isk of
j erking while braking if the trailer wheels lock up .

Wear Brake pad
wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently
in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy ra in, after overnight con­
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica ­
tions.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time. This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
f ir st when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avo iding heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty brake pads .
If you usually avoid heavy braking or if there is
corros ion present, occasional heavy braking at
high speeds is recommended to clean the brake
rotors and
pads¢ &..
Brake system malfunction
If you notice that the brake pedal travel has sud­
denly
increased, then a brake circuit in the dual­
circu it brake system may have malfunct ioned.
Drive to an authorized Aud i dealer or authorized
Intelligent Technology
Audi Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake peda l harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur . The brake fluid level
is e lectronically monitored.
Brake booster
T he brake booster amplifies the press ure you ap­
ply to the brake pedal. It on ly works w hen the en­
gine is running.
A WARNING
-
-Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permit. You must not en­
danger other road users. This increases the
risk of an accident .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
- New brake pads do not ach ieve the ir full
braking effect dur ing the first 250 m i
(400 km). They must be "broken in" first .
However, you can compensate fo r the
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy b rak­
ing during the break -in period.
- Ce rtain weather and operating conditions
such as driving through water, dr iv ing in
heavy rain or driving after washing your ve ­
hicle can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap­
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im­
pa ired by dr iv ing for long stretches on roads
covered with salt without using the brakes.
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes several times.

Checking and Filling Fuel
Gasoline grade
A pplies to: ve hicles with gasoline engines
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven with
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additiona l information on TOP TIER Deter­
gent Gasoline can be found on the official web­
site (www .topt iergas.com).
The individual gasoline grades are differentiated
by
octane ratings. T his value is given with (R +M)/
2 equating to AKI or in RON.
The following headings match the corresponding
sticker in the fuel fi ller door.
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regular/ MIN. RON 91 Regular
Use regu lar gasoline with minimum 87 AKI/
91 RON
i::> (@ .
The maximum engine power is only reached if
premium gasoline 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN . (R
+M)/2 91 / SUPER MIN. RON 95
Using premium gasoline with minimum 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also
use regular gasoline 87 AKI/ 91 RON . However
this does reduce the engine power slightly.
({D) Note
-Fill in g the tank just one time with leaded
fuel or other metallic additives will cause
permanent deterioration to the catalytic
converter function.
- When gasoline with an octane rating that is
too low is used, high speeds or heavy engine
load can lead to eng ine damage.
Checking and Filling
(D Tips
The vehicle may be filled with fuel that has a
higher octane rating than what is required by
the engine .
Blended gasoline
Applies to : vehicles wi th gasoli ne e ngi ne
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al ­
coho l or MTBE (commonly referred to as oxygen­
ates) if the blended mixture meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must contain no more than
3% metha-
nol.
- Blend must contain more than
2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must not conta in more than
15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend must not contain more than
15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iving . Dur­
ing seasonal change-over, we suggest that you
fill up at busy gas stat ions where the seasonal
adjustment is more likely to be made in time .
@ Note
-Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plast ic and rubbe r components in the
fuel system.
- Do not u se fuels that fail to meet the speci-
fied criteria in this chapter.

stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running for a
short time. This is norma l and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
quired, we strong ly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your veh icle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
o il, let the eng ine cool down to the touch.
-
-When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine .
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Cont inuous contact w ith used engine oil is
harmful to your sk in. Always protect your
sk in by washing oil off thoroughly w ith soap
and water.
@ Note
Never mix oil addit ives with your engine o il.
These additives can damage your eng ine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
Checking and Filling
@) For the sake of the environment
-Before changing your oi l, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine oi l properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled wit h a mixture
of purified water and coolant additive at the fac ­
tory. This coolant must not be not changed.
T he coolant level is monitored through
the . in­
dicator light
r=:>poge 13. However, we do recom­
mend occasionally checking the coolant leve l
manua lly.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coo lant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freezing and
corrosion protection agents. Only use the follow­
ing coolant additives. These additives may be
mixed with each other .
Coolant additive Specification

Checking the engine coolant level
• Park the vehicle on a leve l surface .
• Switch the ignition off.
• Read the coolan t leve l on the coo la nt expansion
tank~ page 192, fig . 179. The coolant level
must be between the MIN and MAX markings

• Let the engine cool down .
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockw ise
~ & -
... Add coo lant m ixed in the cor rect ratio
~ page 195 up to the MAX marking.
• Make sure that the fluid level remains stab le .
Add more coolant if necessary .
• Close the cap securely.
Coolant loss usually ind icates there is a leak . Im­
mediate ly drive your vehicle to an authorized
Audi dealer or authorized Audi Service Fac ility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheat ing
and being pushed out of the cooling system .
A WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion ta nk cap
when the engine is hot. This increases the
risk o f bur ns.
- The coolan t addi tive and the coolant can be
dangerous to your health. For t his reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. A ir cou ld enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Serv ice Facility for assis­
tance.

Checking and Filling
(D Note
If the vehicle will be parked for long periods
of t ime , protect it against the co ld so that it
will not be destroyed by "freezing"
c;,page 198 .
Vehicle battery
The term "vehicle battery " refers to the 12 Volt
bat tery in your vehicle.
Not running the vehicle for long pe riods of
t ime
If you do not drive your vehicle for several days o r
weeks , electri cal equipment is gr adually scaled
back or switched off . This reduces energy use and
ensures the veh icle w ill be able to start after long
periods of
time r:::;, page 123 . Some conve nience
functions, s uch as interior lighting or power seat
adj ustment, may not be available under certa in
circumstances. These convenience f unct ions w ill
be ava ilab le aga in once you switch the ignition on
and start the engine .
E ven w hen electrica l equ ipme nt is swi tched off,
the equipment can still d rain the vehicle battery
if the vehicle is not driven for long periods of
time . Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery .
The vehicle battery must be charged every month
t o reduce the risk of this happening

Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING -
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases .
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-volt rating . The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah " rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c>page 189.
@ Note
- Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
( + ) terminals are connected.
