Repl acing wheel s/tires
Vehicles wi th all wheel drive must a lways have tires of t he same size.
Also avoid tires with different tread depths. For details see page
=> page 307, "New tires and rep lacing tires and wheels".
Off -Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road veh icle . It is therefore best to avo id ro ugh tracks and uneven
terrain as m uch as possible . Also refer to=>
page 251.
& WARNING
Alway s adju st your driving to road and traffi c conditi ons. Do not
let the ex tra safety afforded by all wheel dr ive tempt you into
taking extra risks.
• Although the all wheel dri ve is ve ry effecti ve, always
remember that braking capacity is limited by tire traction. You
should therefore not dri ve at ex cessive speeds on icy or slippery
road surfaces .
• On wet road surfaces , be careful not to drive too fast because
the front wheel s could begin to slide on top of the water (aqua­
planing ). If th is should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle. Always drive at speeds which are suited to the road cond i­
tions -ris k of crash.

Energy management
Starting ability is optimized
E
nergy management contr ols th e distributi on of elec­
tri cal energy and thus optimizes the availabili ty of elec­
tri cal energ y for star ting the engin e.
If a vehicle with a conventiona l energy system is not dr iven for a long
per io d of time, t he battery is di sch arged by idling cur rent consume rs
(e .g. immob il izer) . In certain c ircumstances it can result in there
being insuffic ien t energy av a ilab le to start t he eng ine .
Inte lligent energy management in your ve hicle hand les the d istribu ­
tion of e lectrical energy . Starting ability is ma rkedly improved and
the l if e of the battery is extended.
Bas ically, energy management consists of
battery d iagnos is, idling
current management
a nd dynamic energy management .
Battery diagnosis
Battery d iagnosis con tinuously dete rmines the st ate o f the batte ry.
Sensors determ ine battery vo ltage, battery current and battery
t empe ra ture. This de termine s the cur rent sta te of cha rge and the
power of the battery.
Idling current management
I d ling current management reduces energy consumption wh ile the
vehicle is s tanding. W ith t he igni tion swi tched off, it con trols the
energy supply to the var io us electrical components. Data from
b att ery diag nosis is considered .
Depend ing on the battery 's state of charge, individual consumers a re
gradually t urned off to p revent excessive discha rge of the battery and
thus main tain start ing capab ility.
Dynamic energy management
Whi le the vehicle is being dr iven , dynamic energy management
dis tributes the energy generated a cco rding to the needs o f th e in di-

Observe speed limits. In some areas, speeds for vehicles towing
t railers are lowe r than for regular veh icles.
Always apply brakes early. When dr iv ing downh ill, sh ift in to a lower
gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge~ page 8 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditione r.
If the coolant temperature warning light in the instrument cluster
star ts flashing
-t- , pull off the road, stop and let the engine idle for
about two minutes to prevent heat bu ild-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi. u
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a tra iler because of the
additiona l weight and different weight distribution. Safety, perfor ­
mance and economy will greatly depend on how carefu lly you load
your trailer and operate your rig .
Before you actua lly tow your trailer, practice turning, stopping and
backing up in an area away from traffic. Keep pract icing until you have
become completely familiar with the way your vehicle-t railer combi­
nation behaves and responds.
Controls and equip­
ment Safety first Vehicle operation
Backing up
is d iff icult and requ ires 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 fo r the
trailer, you will need a larger than norma l 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 you r
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes .
[I) Tips
• Do not tow a trai ler during the break-in per iod of your vehicle.
• If you tow a tra iler, your Audi may requi re more frequent mainte­
nance due to the extra toad~
page 343. •
Parking on a slope
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 se lector lever to
P.

- Release the parking brake and slowly pull out and away
from the wheel chocks .
- Stop and have someone retrieve the wheel chocks.
(I] Tip s
If you move the se lector lever of the automat ic transm ission* to P
before applying the parking brake and before blocking the wheels,
you may have to use mo re force late r to move the lever out of the
P
position.

Under certain circumstances, weekly washing may be necessary .
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the underside of the vehicle shou ld be thoroughly
washed preferably in a professional car wash.
& WARNING
Always read and heed all WARNINGS and other information
~page 260. •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
Th e vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However, the
effect on the paint depends to a lar ge exten t on the design of the
facility, the filtering of the wash water, the type of wash and care material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash.
The power top does not require special precautions before passing
through a car wash .
However, the car must not be treated with hot
wax after the wash cycle!
The wax could adverse ly affect the power
top and even damage the fabr ic over a period of time .
The power top does not have to be washed every time you use a car
wash. The power top can be spared if the car wash facility is equ ipped
with manually adjustable roof brushes or rollers.
Before going thro ugh a car wash, be sure to take the usual precau­
tions such as closing the windows . Remove antenna if applicable.
If you have installed additional accessories on the vehicle -such as
spoilers, etc. -it is best to ask the car wash operator if these should
be removed.
