.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often . This could cause the
brakes to get hot and dimin ish b raking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the b rakes to
overheat, premat ure wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa
ter , driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
Int ellig ent technolog y 201
for a test. Brakes will dry and ice coat
ings w ill be cleaned off after a few care
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
f low to the front brakes is not obst ruct
ed. Otherw ise the brake system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one brake circuit will impair
the braking capability resulting in an in
creased stopping distance . Avoid driving
the vehicle and have it towed to the near
est a uthori zed Audi dea ler or qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

212 Trailertowing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen
ger transportation .
If you plan to tow a trai ler, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
T ra ile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita
ble for your vehicle and trailer and mu st be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
h itch with a removable ball mount. A lways
check with the trai ler h itch manufact urer to
make sure that you are using the correct
hitch.
Do n ot use a bumper hi tch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb
ing bumper system . No modifications should
be made to the vehicle exhaust and brake sys
tems . From t ime to time, check that all hitch
mounting bo lts remain securely fastened.
When you are not towing a trailer, remove the
trailer h itch ball mount. This prevents the
h itch from causing damage should your veh i
cle be struck from behind
¢ A .
Traile r brak es
If your tra iler is equipped w ith a braking sys
tem, check to be sure that it conforms to a ll
regulat ions . The trailer hydraulic brake system must not be
direct ly connected to the vehicle's hydraulic
brake system
~ A .
Saf ety ch ain s
Always use safety chains between your veh icle
and the trai le r.
Trail er light s
Trailer lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct wiring, sw itches, and relays.
Mirror s
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors .
It is important
that you always have clea r vis io n to the rear.
,8. WARNING
- I f a trai ler has electrical brakes p lease
note that these brakes are not activated
by the factory -fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve
h icle. The vehicle was not designed for
these kinds of trailer h itches. The h itch
attachment can fail, caus ing the trailer
to tear loose from the veh icle.
- The Gross Vehicle Weight Rating for your
veh icle, found on the safety compliance
label on the driver's s ide B-pillar, must
never be exceeded under any c ircumstan
ces. Exceeding the Gross Vehicle Weight
Rating of yo ur vehicle is likely to damage
your vehicle, and such damage will not
be covered by yo ur Limited New Ve hicle
Warranty . Exceeding the Gross Vehicle
Weight Rating will a lso change the per
formance and handling characteristics of
your veh icle, wh ich could cause a crash
resulting in serious injury or death.

Fig. 190 Permit ted ball position of the trailer hitch
Trailer towing weights
With a factory-installed or an aftermarket
trailer hitch, the maximum permissible trailer
weight is 4,400 lbs (2,000 kg). The maximum permissible unbraked trailer weight is 1,650
lbs (750 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 al
lowable or slightly lower . You can get an ap
proximation of the tongue load with a bath
room scale or you can measure the load at a
trucking company or weighing station.
With a
factory-installed or an aftermarket
trailer hitch, the maximum permissible load
on the ball hitch may not exceed 440 lbs
(200 kg).
It is recommended to use the maxi
mum permissible load.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢.&. in Driving instructions on page 214.
Ball mount
The trailer hitch may only be used with suita
ble ball mount and ball¢
fig. 190. Installa
tion of the hitch ball must be carried out in ac-
Trailer towing 213
cordance with the manufacturer's instruc
tions.
Engine cooling system
Towing a trailer makes the engine work hard
er .
It is important that the cooling system's
performance 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 cold tire pressure listed under
"Full load" on the tire pressure label. The tire
pressure label is located on the driver's side B
pillar. Inflate trailer tires to trailer and tire
manufacturers' specifications.
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 con
nected from the trailer to the hitch on the ve
hicle. Leave enough slack in the chains to per
mit turning 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.
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 following :
.,. Do not tow a loaded trailer when your car it
self is not loaded .
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits.
•
•

214 Trailer towing
• Do not drive at the maximum permissible
speed.
• Always apply brakes early .
• Monitor the temperature gauge.
W eig ht distribution
Towing a loaded tra ile r with an empty car re
sults in a highly unstable distribution of
weight . If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con
trol. This means that the tow vehicle should
be loaded to the extent possible and permissi
b le, while keeping the trailer as light as possi
ble under the circumstances. Whenever possi
ble, transfer some cargo to the luggage com
partment of the tow vehicle wh ile observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be
comes for the driver to control the rig . Do not
drive at the maximum permissible speed . Re
duce your speed eve n mo re if load, weathe r or
wind condi tions are unfavorable -part icu larly
when going dow nhill.
Reduce vehicle speed immediately if the t rail
e r shows the slightest sign of swaying. Do not
tr y to s top the sw ayin g by acce ler atin g.
Observe speed limits . In some areas, speeds
for vehicles towing trailers are lower tha n for
regula r vehicles.
Always apply brakes early . When driv ing
downhill, shift into a lower gear to use the en
g ine b raking effect to slow the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
T he coolant temperature gauge
c:> page 10
must be observed carefully . If the needle
moves close to the upper end of the scale , re
duce speed immed iate ly and/or turn off the
a ir cond itione r. If the coolant temperature warning light in
the instr ument cluster starts flashing., pull
off the road, stop and let the engine
idle for
about two minutes to prevent heat build-up.
A WARNING
Anyone not properly restrained in a mov
i ng vehicle is at a much greater risk in a n
accident . Never let anyone ride in your ca r
who is not p roperly wea ring the rest raints
p rov ided by Audi.
Trailer towing tips
Important to know
Your vehicle handles d ifferently when towing
-
a trai ler because of the additional weight and
different weight distr ibut ion. Safety, perform
ance and economy will greatly depend on how ca refully you load your trai ler and ope rate
you r rig.
Befo re you actually tow your tra iler, practice
turning, stopping and backing up in an area
away from t raffic. Keep pract ic ing unt il you
have become completely familiar wit h the way
yo ur vehicle-tra iler combination behaves and
responds.
Backi ng up is difficult and requ ires practice.
Backi ng up w ith a t railer gene rally requires
stee ring action opposite to tha t when backing
u p you r vehicle witho ut a tr ailer.
Maintai n a greater d ista nce between your ve
hicle and the one in front of you. You w ill need
more room to stop. To compensate fo r the
t railer, you w ill need a larger than normal
tu rning rad ius.
When passing, remembe r that you cannot ac
ce le rate as fas t as you no rma lly would be
ca use of the added load. Make sure yo u have
enough room to pass . After passing, a llow
plenty of room for yo ur trailer before cha ng
ing lanes again.
Avoid jer ky s tarts, sharp t urns o r rapid lane
changes.

-Always make sure that the total load be
ing transported - including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi
cle heav ier than the vehicle's Gross Vehi
cle Weight Rating.
Determining correct load limit
Use the example below to cal
culate the total weight of the
passengers and luggage or oth
er things that you plan to trans
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your ve
hicle's placard (tire inflation
pressure label)
¢ page 252,
fig. 203.
2. Determine the combined
weight of the driver and pas sengers that will be riding in
your vehicle.
3. Subtract the combined
weight of the driver and pas sengers from
"XXX" kilo
grams or
"XXX" pounds
Tires and wheels 257
shown on the sticker
¢page 252, fig. 203.
4. The resulting figure equals
the available amount of car
go and luggage load capaci
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five
150
lbs. passengers in your vehi
cle, the amount of available
cargo and luggage load ca
pacity is
650 lbs. (1400-7 50
(5
X 150) = 650 lbs.)
5. Determine the combined
weight of luggage and cargo being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step
4.
6. If your vehicle will be towing
a trailer, load from your trail
er will be transferred to your
vehicle. Consult this manual
to determine how this re duces the available cargo
and luggage load capacity of
your vehicle.
.,. Check the tire sidewall
(¢ page 259, fig. 207) to de
termine the designated load rating for a specific tire.
