Operating instructions
Max im um tra iler weight
A trailer for your vehicle is limited to a typical class 1 or class 2
trailer.
T ra ile r l oa d di stributio n
Be sure the load in the trailer is he ld securely in place to prevent it
from shifting forward, backward or sideways .
Never allo w a passe nger to r ide in a tr aile r~ & in "Driving instruc­
tions" .
Engin e c oolin g sys te m
Towing a trailer makes the eng ine work harder. It is important that
the cooling system's performance is up to the additiona l load. Make
sure that the coo ling system has enough fluid .
Tire pr ess ure
When towing a trailer, inflate the tires of your vehicle to the co ld tire
pressure listed under "Full load" on the labe l located either on the
driver's side B -pil lar (visible when the door is open) or inside the fuel
filler flap . Inflate trai ler tires to trai ler and tire manufacturers' spec­
ifications.
L ig ht s
The head light settings should be checked wit h the trai ler attached
before driving off. Check to make sure both vehicle and trai ler lights
are working properly .
Safe ty c ha in s
Be sure traile r safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
perm it turning corners . When you i nsta ll safety chains, make sure
they will not drag on the road when you are driving.
T he chains should cross under the trailer tongue to prevent it from
dropping in case of separat ion from the hitch.

Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of veh icle and trailer,
please note t he following :
- Do not tow a loaded trailer when your car itself is not
loaded.
Be espec ia lly careful whe n passing other vehicles.
- Observe s peed limits .
Do not drive at the maximum permiss ible speed .
Always apply brakes ear ly.
Moni tor t he temperature ga uge.
Weight distr ibution
Towing a loaded trailer with an empty car results in a highly
unstable distr ibution 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 control. This means that
the tow vehicle should be loaded to the extent possible and perm is ­
s ib le, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfe r so me cargo to t he luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considera tions . .,

Speed
The higher the speed, the more difficult it becomes for the driver to
control the rig. Do not drive at the maximum permissible speed. Reduce your speed even more if load, weather or wind conditions
are unfavorable -particularly when going downhi ll.
Reduce vehicle speed
im med ia tel y if the trailer shows the slightest
sign of swaying.
Do not try to s top the swayi ng by accelerating.
Observe speed limits. In some areas, speeds for vehicles towing
trai lers are lower than for regular vehicles .
Always apply brakes ear ly. When driving downhill, shift 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.
C ool ant t emp era tur e
The coolant temperature gauge=> page 12 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immed iately and/or turn off the air conditioner.
If the coolant temperature warning light in the instrument cluster
starts flashing
- F- , pull off the road, stop and let the engine idle for
about two minutes to prevent heat build-up.
& WARNING

g re ater ri sk in an accident . Never let any on e r ide in y our car who
is n ot pr operl y wea ring th e re stra ints pr ovided b y Audi . •
Trailer towing tips
Important to know
Your vehicle handles differently when towing a trailer because of
the additional weight and different weight distribution. Safety, performance and economy will greatly depend on how carefully you
l
oad your trailer and operate your r ig.
Before you actually tow your trailer, practice turning, stopping and
backing up in an area away from traffic . Keep practicing unti l you
have become comp letely familiar with the way your vehicle-trai ler
combination behaves and responds.
Back ing up is difficult and requires practice. Backing up with a
trailer generally requires steering action opposite to that when backing up your vehic le without a tra iler.
Ma intain a greater distance between your veh ic le and the one in
front of you . You will need more room to stop. To compensate for
the trai ler, you w ill need a larger than norma l turning radius.
When passing, remember that you cannot accelerate as fast as you nor mally wou ld because of the added load . Make su re you have
enough room to pass. After passing, allow plenty of room for your
trai ler befo re changing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
[ i ] T ips
• Do not tow a trailer during the break -in period of your vehicle.
• I f you tow a trailer, your Audi may require more frequent main te­
nance due to the extra load=>
page 382. •
Parking on a slope
Do n ot park on a slope with a trailer. If it cann ot be
avoi ded, do so only after d oing the followi ng:
When p arking :
-Apply the foot brake.
- Have someone p lace chocks under both the vehicle and
the trailer wheels. ._

crashes and serious personal in jur ies . Have worn or da maged t ires
replaced immediately .
• Tires age even if they are not being u sed and can fail suddenly ,
especially at high speeds. T ires that are more than 6 years old can
only be used in an emergency and then w ith special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the co mbined we ig ht ( in excess o f those sta nda rd items
which may be rep laced) of automatic transmission, power steering,
power brakes, power w indows, powe r seats, rad io, a nd heater, to
the extent that these items are avai lab le as factory-installed equip­
m ent (w hether insta lled or not).
Aspect ratio means t he ratio o f th e height to t he w idt h of the tire in perce nt.
N umbers of 55 or lower indicate a low sidewa ll for improved

• Never mount used tires on your vehicle if you are not sure of
their "previous history. " Old used t ire s may ha ve been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and lo ss of vehicle control.
• If you noti ce unusual vibration or if the vehicle pulls to one side
when driving , always stop as soon as it is safe to do so and check
the wheels and tires for damage . •

Tires and wheels -_______________ _____.
Tire service life
The service life of tires depends on a lot of different things
including proper installation and balancing, correct tire
pressure and driving style.
_/l
l '-------- ,)
Tread Wear Indicator (TWI)
Fig. 276 Tire tread:
tread wear indicators
(TWI)
Fig . 277 Rotating tires
for more even wear
The original tires on your vehicle have 1/16 inch (1.6 mm) high "wear
indicators":::::, fig. 276 running across the tread. Depending on the
make, there will be six to eight of them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions of the tread wear indicators. Worn tires must
be replaced. Different figures may apply in other countries.:::::,&.
Tire pressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month .:::::,
page 333.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals. Please
remember the following:
• Tire rotation intervals may differ from the vehicle service inter­
vals outlined in your Warranty
& Maintenance booklet.
• The longer one tire is used in one location on the vehicle, the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer 's suggested tire rotation intervals .
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro®l .
• Please rotate tires as shown .:::::, fig. 277.
• Extra care must be taken when rotating direction -specific tires
:::::, page 359.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usually feel through the
steering wheel.
Unbalanced wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed. _,,
