W eig ht dis tri buti on
Towing a loaded trailer with an empty car resu lts in a high ly
unstable distribution of weight . If this cannot be avoided drive at
ve ry low speeds only to avoid the risk of los ing steering control.
A "ba lanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and permis ­
sib le whi le keeping the trailer as light as possib le under the circum ­
stances. Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle while observing tongue load
requirements and vehicle loading considerations .
Speed
The higher the speed, the more difficult it becomes for the driver to
contro l the rig . Do not drive at the maximum permissible speed.
Reduce your speed even more under unfavorable load, weather or
wind condi tions -particularly when going downhill.
Reduce vehicle speed
imm ed iately if the trailer shows the slightest
sign of swaying.
Do not try to stop the s waying by a ccelerating .
Observe speed limits. In some areas speeds for vehic les towing
trai lers are lower than for regular vehicles.
Always app ly brakes early. When driving downhill, shift into lower
gear to use the engine braking effect to slow down the vehicle. Use
of the brakes alone can cause them to overheat and fail.
C oo lan t tem pe ra ture
The coolant temperature gauge~ page 73 must be observed care ­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or switch off the air conditioner.
If the coolant temperature warning light in the instrument cluster
starts flashing -~- , pul l off the road, stop and let the engine
idle for
about two minutes to prevent heat build -up .
& WARNING
An yone not prop erl y r estr ained in a mo ving ve hic le is at a much
gre ater ri sk in an accident. N ever let an yone rid e in your car who
is not p roperl y wearing the r estraint s pro vid ed by Audi.
c
Trailer towing tips
Important to know
Your vehicle handles differently when towing a trai ler because of
the additional weight and weight distribution . Safety, performance
and economy will great ly depend on how carefu lly you load your
trai ler and operate your rig.
Before you actually tow your trailer, practice turn ing, stopping and
backing up in an area away from traffic. Keep practicing unti l you
have comp letely become familiar with the way your vehicle -trailer
combination behaves and responds .
Backing up is difficu lt and requires practice. Backing up with a
trailer genera lly requires s teering action opposite of that when
backing up your vehic le without a trailer.
Maintain a greater distance between you r vehicle and the one in
front of you. You will need more room to stop.
To compensate for the trailer, you wi ll need a larger than normal
turning radius .
When passing, remember that you cannot accelerate as fast as you nor mally wou ld because of the added load . Make sure yo u have
enough room to pass. After passing, allow plenty of room for your
trai ler before changing lanes again .
Avo id jerky starts, sharp turns o r rapid lane changes.

[ i ] Tip s
• 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 ex tra load=>

Parking on a slope
---'--------------------
Do not park with a trailer on a slope. If it cannot be
avoided, do so only after doing the following:
Wh en p arking :
-Apply the foot brake.
- Have someone p lace chocks under both the veh ic le and
the trailer wheels .
- Wit h chocks in p lace, s low ly release t he brakes until
wheel blocks absorb t he load.
- T urn t he wheels towards the curb .
- Apply the parking brake .
- Place an automatic transmission in
P , respect ively a
manual transmission in first or reverse gear.
Wh en restarting after p arking :
- Start the e ngine .
- Shift transmiss ion into gear.
- Re lease the parking brake and slowly pull out and away
from the w heel blocks.
- Stop and have someone retr ieve t he wheel blocks.

[ i ] Tip s
If you move the selector lever of the automatic transmission to P
before applying the parking brake and before blocking the wheels,
you may have to use more force later to move the lever out of the
P
position .•

Closing the engine hood
-Pull t he hood down until the pressure from the strut is
reduced.
- Let t he hood
drop down and latch in place. Do not try to
push it shut;
it may fai l to engage ~& .
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area
~ 6 .
& WARNING
To help avoid injury, before you check anything under the hood :
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park);
put manual transmission in Neutral.
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood .
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire.
• Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary :
- Always disconnect the battery .
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine
is running or being started, never touch :
- Ignition cables
- Other components of the high voltage electronic ignition
system.
• If you must perform a check or repair with the engine running:

Tires and wheels -
----------------
•
• The tire pressures should only be checked and adjusted when
t he t ires are co ld . The s lightly raised press ures of warm tires must
not be reduced .
• Adjust t he tire p re ssure to the load you are carrying.
• Reinstall the va lve stem cap on the valve.
When should I check the tire pressure?
The correc t tire p re ssur e is espec ially i mportant at high speeds. The
pressure should there fore be c hecked at least once a month and
a lways before starting a journey. Do not forget to check the tire pres ­
su re for t he spare whee l::::>
page 291.
When should I adjust the tire pressures?
Adjust the ti re pressur e to the load you are carrying. A fter chang in g
a wheel
or replacing whee ls you have to adj ust t he t ire pressure s on
a ll whee ls. In addition, o n ve hicles w ith t ire pressure monito ring
system * you must then store the new tire pressures in the system
=> page 41.
& WARNING
Incorrect tire pres sures and /or underinflation can lead sudden tire
failure, loss of control , collision, serious personal injury or even
death .
• When the warning symbol ( appears in the instrument
cluster , stop and inspect the tires .
• Incorrect tire pressure and /or underinflation can cause
increased tire wear and can affe ct the handling of the vehicle and
stopping ability .
• Incorre ct tire pressures and /or underinflat ion can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehi cle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle . The appli cable pre ssure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
& WARNING (continued )
• Only when all tires on the veh icle are filled to the correct pres­
s ure, the tire pressure monitoring system * 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 values for the tires and the correct pres­
sures for the function of the tire pressure monitoring system*.
• Alway s inflate tires to the recommended and corre ct 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.
• Excessive speed and /overloading can cause he at build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high , the tires 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 che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
valves. To p revent this, a lways make sure tha t factory installe d va lve
stem caps on al l wheels are securely mounted on the va lve .
<£> For the sake of the environment
Underinflated tires wi ll a lso increase the fue l consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehic le and
any tire can carry. A vehicle that is overloa ded wil l n o t handle well _,.
