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
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 become completely familiar with the way your vehicle -trailer
combination behaves and responds.
Backing up is difficult and requires practice. Backing up with a
trailer generally requires steering action opposite to that when
backing up your vehicle 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 accelerate 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.
[ i] Tips
• Do not tow a trailer during the break-in period of your vehicle. • If you tow
a trailer, your Audi may require more frequent mainte­
nance due to the extra load~
page 401. •
Parking on a s1ope
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 vehicle 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.
- Move the selector lever to
P.
When restarting after parking:
- Apply the foot brake.
- Start the engine.
- Move the selector lever to
D.
-Release the parking brake and slowly pull out and away
from the wheel chocks.
- Stop and have someone retrieve the wheel chocks.
[ i] Tips
I f you move the selector lever of the automatic transmission to P
before applying the parking brake and before blocking the wheels, II-

you may have to use more force later to move the lever out of the P
position .•

Technical data

Tires a nd wh eels -
----------------
•
Because technical changes may be made to vehicle equipment
during the mode l year, always compa re the tire size designation on
the tire pressure label on your vehic le with the tires on your vehicle.
Make sure that the tire size information on the vehicle labe l is the
same as the size of the tires on the vehicle . This is especially impor­
tant if the vehicle belongs to someone else or you bought the
veh ic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers also depends
on making sure that load limits are not exceeded. Vehicle load
includes everybody and everything in and on the vehicle . These load
limits are technically referred to as the vehicle's Gross Vehicle
Weight Rating ("GVWR"l. The Gross Axle Weight Rating ("GAWR"l is
the maximum load that can be applied at each o f the vehicle's two
ax les . The Gross Vehic le Weight Rating and the Gross Ax le Weight
Rating are l isted on the safety compl iance sticker labe l located
either on the driver's side 8 -pillar or on the inside of the fuel fi ller
flap. The ti re pressure labe l on your Audi lists the maximum
combined we ight of a ll of the occupants and luggage or other cargo
t hat the vehic le can carry. For the location of the tire pressure la bel

c au sin g lo ss of vehi cle co ntr ol. •
Checking tire pressure
The correct tire pressure for the tires originally installed
o n your vehicle is listed on the tire pressure label located
either on driver's side 8 -pil/ar or inside the fuel filler flap .
The recommended tire pressures are on the tire pressure label and
in the table=>
page 351, "Cold tire inflation pressure" .This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of mi les (kilomete rs} at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal fric tion as i t flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold ."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Co ld tire inflation
pressure" recommendations=>
page 351 . The tires wou ld then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recomme nded cold tire
inflation pressures at maximum capacity for the new, origina l equip -.,.

& WARNING (continu ed )
• Incorrect tire pressure and /or under inflation can cause
in creased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect t ire pressures and /o r underinflat ion can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing lo ss of vehicle control .
• The driver is respon sible for the correct tire pressures for all
tires on the vehicle. The applicable pre ssure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
• Only when all tires on the vehicle are filled to the correct pres ­
sure , the tire pressure monitoring sy stem can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure value s for the tires and the correct pres ­
sures for the function of the tire pressure monitoring system.
• Always inflate tires to the re commended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build-up ,
s udden tire failure and lo ss of control .
• If the tire pres sure is too low or too high , the t ires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to check the t ire pressure and add air as required.

LJ}. WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident , serious personal injury , and even death .
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handl ing properly and increase the
ri sk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly ,
including a blowout and sudden deflation , causing loss of control
and a crash .
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
& WARNING (continued)
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating .•
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and
luggage or other things that you plan to
transport 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 OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehicle's placard (tire infla ­
tion pressure label)=>
page 351, fig. 291.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
~

3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker=>
page 351, fig. 291.
4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400-750 (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 trailer will be transferred
to your vehicle. Consult this manual to determine how this reduces the avail­
able cargo and luggage load capacity of
your vehicle.

-Check the tire sidewall (=> page 359,
fig. 295) to determine the designated
load rating for a specific ti re. •
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.

Changing a wheel
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing a wheel.
-After you experience a tire failure, pull the car well away
from moving traffic and try to reach
level ground before
you stop => & .
- All passengers should
leave the car and move to a safe
location (for instance, behind the guardrail)=> &.
- Engage the
parking brake to prevent your vehicle from
rolling unintentionally=> &. -
Move
selector lever to position P =:> & .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Block the diagonally opposite wheel with the folding
chocks or other objects.
- Take the
jack and the inflatable spare tire out of the
luggage compartment=>
page 370.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flashers on and use other warning
devices to alert other motorists.
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack , always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed with the
folding chocks or other objects. When one front wheel is lifted off
the ground, placing the Automatic Transmission in "P" (Park) will
not prevent the vehicle from moving.
• Before you change a wheel, be sure the ground is level and firm .
If necessary, use a sturdy board under the jack.
• After installing the inflatable spare tire, make sure that you
replace the flat tire/wheel in its storage area properly and tighten
the knurled retaining screw securely. •

outside temperatures, in very dusty regions, when towing a trailer
very frequen tly, etc., some service work shou ld be performed
between the intervals specified. This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
By regularly maintaining your vehicle, you help make sure that emis­

the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the general ly increasing technical
complexity of today's automobi les, have steadi ly reduced the scope
of maintenance and repa irs which can be carried out by vehicle
owners.
Al so, sa fety a nd e nvironment al concerns p lace very strict
limi ts on the na ture of repairs a nd adjustments to engine and trans ­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing dev ices and other equipment ava ilable to specially trained
workshop personnel in order to assure proper performance, reli ­
ability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs can impair the
ope ration and re liability of your vehic le and even void your vehic le
warranty. Therefore, proof of servicing in accordance with the main­
tenance schedu le may be a condition for upholding a pos sible
warranty claim made within the warranty period. Above all, operational safety can be adversely affected, creating
unnecessary r isks for you and your passengers .
If in doubt about any servicing, have it done by your authorized Audi
dea ler or any other properly equipped and qualified workshop. We
strongly urge you to give your authorized Audi dealer the opportu­
nity to perform all scheduled maintenance and necessary repairs.
Your dealer has the fac ilities, origina l parts and trained spec ial ists
to keep your vehicle running proper ly.
