In order to become familiar with the gearshift indictor, at first just
drive the way you are used to . If the current gear -and the driving situation
-is not the best one for conserving fuel, then the indicator
will display the recommended gear . The display shows the current
gear and the gear that is recommended~ fig. 11.
• Upshifting The display will light up to the right of the gear
currently selected if it is recommending a higher gear.
• Downshifting: The display will light up to the left of the gear
currently selected if it is recommending a lower gear .
Sometimes the indicator will recommend skipping a gear (3
> 51.
If there is no gearshift recommendation, then just drive in the
appropriate gear for conserving fuel.
[ i ] Tips
• This indicator can help you conserve fuel. This indicator is not
meant to show you which gear you should always be in in all driving
situations. Sometimes , in situations such as passing , driving
through mountains or when towing a trailer, there won't be any
gearshift recommendation.
• The disp lay does not light up when the clutch peda l is being
depressed .•

& WARNING
Pedals that cannot move freely can cause loss of vehicle control
and increase the risk of serious injury.
• Never place any objects in the driver's footwell . An object could
get into the pedal area and interfere with pedal function. In case
of sudden braking or an accident, you would not be able to brake
or accelerate!
• Always make sure that nothing can fall or move into the
driver's footwell. •
Floor mats on the driver side
Always use floor mats that can be securely attached to
the floor mat fasteners and do not interfere with the free
movement of the pedals.
- Make sure that the floor mats are properly secured and
cannot move and interfere with the pedals =>& .
Use only floor mats that leave the pedal area unobstructed and that
are firmly secured so that they cannot slip out of position . You can
obtain suitable floor mats from your authorized Audi dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached to these fasteners .
Properly securing the floor mats will prevent them from sliding into
positions that could interfere with the pedals or impair safe opera­
tion of your vehicle in other ways.
& WARNING
Pedals that cannot move freely can result in a loss of vehicle
control and increase the risk of serious personal injury.
• Always make sure that floor mats are properly secured.
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued)
• Never place or install floor mats or other floor coverings in the
vehicle that cannot be properly secured in place to prevent them
from slipping and interfering with the pedals or the ability to
control the vehicle.
• Never place or install floor mats or other floor coverings on top
of already installed floor mats. Additional floor mats and other
coverings will reduce the size of the pedal area and interfere with
the pedals.
• Always properly reinstall and secure floor mats that have been
taken out for cleaning.
• Always make sure that objects cannot fall into the driver foot­
well while the vehicle is moving. Objects can become trapped
under the brake pedal and accelerator pedal causing a loss of
vehicle control. •

Low brake fluid level
Ma lfu ncti ons can occ ur in th e brake system if the bra ke flu id leve l is
too low. The brake fluid leve l is monitored e lectronically.
Brake lining wear status Bra ke lining wear may be checked by visual inspection of the condi ­
t ion of the brake pa ds through the o pen in g s in t he wheel. If neces ­
sary, the wheel may be removed for this inspection=>
page 312,
" C hanging a whee l" .
& WARNING
• You should perform braking maneuver s for the purpose of
cleaning the brake system only if road cond itions permit . Other
road u sers must not be put at risk -you may cause an accident !
• Before des cending a steep grade , reduce speed and shift trans ­
mission into a lower gear or lower driving range. Do not ride the
brake s or hold the pedal down too long or too often . This could
c ause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake. This may cause the brakes to overheat, p rem ature wear and in creased stopping distance .
• Under certain climatic and operating conditions such as
passing through water , driv ing in heavy rain or after washing 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 for a test. Brakes will dry and ice coatings
will be cleaned off afte r a few careful b rake appli cations .
• Driving for an extended period of time on salt -covered roads
without using your brakes can also affe ct braking effic ien cy. 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 flow to the front brakes is not obstru cted .
Otherwise the brake system could overheat reducing the effe ctive­
ness of the entire brake system .
& WARNING (continued )
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping distance . Avoid driv ing the
vehicle and have it towed to the nearest authorized Audi dealer or
qu alified workshop. •
Brake booster
The bra ke boos ter adds e xtra bra king pow er.
Th e brake boost er wo rks wit h vacuum p ressu re wh ich is created
only when the engine is running=>& .
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working , for e xample 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 . •
Functioning of Anti-Lock Brake System (ABS}
A BS p revents t he wheels from lockin g up unde r braking.
The ABS co ntrib utes effectively to ve hic le c ont ro l since it preven ts
the whee ls from locking when the bra kes are app lied. Th is means
that the vehicle remains stee rable and is less l ikely to skid .
With ABS you do not need to
pump the brake. Just hold the brake
pedal down .
Ho wever , do not e xpect the AB S to sho rten braking d istance under
all circumstances. When driving o n grave l or on newly fallen snow
o n t op of icy su rfaces, b raking distance may be even lo nger, there ­
f ore, unde r these circumsta nces, it is especially impo rtan t th at you
drive slow ly and with great ca re. ._

-Traile r t ow ing
----- -=---------------------------------
Tr a ii er towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor­
tation.
If you plan to tow a trailer, please remember that the additional load
wi ll affect durability , economy and performance.
Trai ler towing not on ly p laces more stress on the vehicle, it a lso ca lls
for more concentration from the driver.
For this reason, always fol low the operating and driving instructions
provided and use common sense. •
Technical requirements
Traile r hit ch
Use a weight -carrying hitch conforming to the gross trailer weight.
The hitch must be suitab le for your vehicle and tra iler and must be
mounted secure ly on the vehicle's chassis at a
technically sound
location . Use only a trailer hitch with a removable ball mount.
Always check with the trai ler hitch manufacturer to make sure that
you are using the correct hitch.
D o not u se a b umper hit ch .
The hitch must be installed in such a way that it does not interfere
w ith the impact-absorbing bumper system . No modifications
should be made to the vehicle exhaust and brake systems . From
time to time, check that all hitch mount ing bolts remain securely
fastened.
When you are not towing a trailer, remove the trailer hitch ball
mount. This prevents the hitch from causing damage should your
vehic le be struck from behind =:> & .
Tra iler br akes
If your trailer is equipped with a braking system, check to be sure
that it conforms to al l regu lations.
T he trailer hydraulic brake system must not be directly connected to
the vehicle's hydraulic brake system=:>& .
Safet y cha ins
Always use safety chai ns between y our vehicle and the trailer .
Traile r lights
Trai ler lights mus t meet all regulations. Be su re to check with your
authori zed Audi dealer for correct wiring, switches, and relays .
Mirrors
If you are unable to see the traffic behind you using the regu lar
outside mirrors, then you
must instal l extended m irrors. It is impor ­
tant that you
always have to the rear .
& WARNING
• If a trailer ha s el ectri cal brake s please note that the se brak es
are n ot act iva ted by the fa ctory -fitted control unit · ri sk of acc i­
dent !
• After remo ving the tr ailer hit ch , d o n ot store it in yo ur vehi cle.
In ca se of sudden b raking , th e hitch could fly forw ard and injure
you or your p assengers . •
Operating instructions
M ax imum tr aile r w eight
A trai ler for your vehicle is limited to a typica l class 1 or class 2
trai ler.

Trailer load d is trib ut ion
Be sure the load in the trailer is held securely in place to prevent it
from shifting forward, backward or sideways.
Ne ver allo w a passen ger to rid e i n a tr ailer => & in "Driving instruc ­
tions" on
page 249.
En gin e c ool ing syst em
Towing a trailer makes the engine work harder. It is important that
the cooling system 's performance is up to the additiona l load. Make
sure that the cooling system has enough flu id.
Ti re press ure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the labe l located either on the
driver's side B-pillar (visible when the door is open} or inside the fuel
filler flap . Inflate trailer tires to trai ler and tire manufacturers' spec ­
ifications.
Ligh ts
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 .
Safe ty c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
permit 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 veh icle and trailer,
please note t he following :
Do not tow a loaded trailer when your car itself is not
loaded .
- Be especia lly careful when passing other vehicles .
Observe speed l imits .
Do not drive at the maximum permissible speed.
Always apply brakes early.
Monitor the temperature gauge.
W eight distrib utio n
Towing a loaded trailer with an empty car results in a h ighly
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 control. This means that
t he tow vehicle should be loaded to the extent possible and permis ­
sible, while 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 whi le observing tongue load
requirements and vehicle loading considerations.
S pee d
The higher the speed, the more difficu lt it becomes for the d river 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 downhill .
Reduce vehicle speed
i mmed iatel y if the trailer shows the slightest
sign of swaying .
Do not try to st op the swa ying b y accelerating.
Vehicle care Do-it-yourself service Technical data

___ T_ r _a_ il_e _r_ t_ o_ vv_ in__... g,_ __________________________________________________ _
Observe speed limits. In some areas, speeds for vehicles towing
trailers are lower than for regular vehicles.
Always apply brakes early. 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.
Coolant temperature
The coolant temperature gauge=> page 8 must be observed care­
ful ly . If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditioner .
If the coolant temperature warning light in the instrument cluster
starts flashing
-F- , pul l off the road, stop and let the engine idle for
about two minutes to prevent heat build-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 . •
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 great ly depend on how careful ly you
load your trailer and operate your rig.
Before you actual ly tow your trailer, pract ice turning, stopping and
backing up in an area away from traffic. Keep practicing unti l 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
t rai ler genera lly 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 trai ler, you wi ll 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, al low plenty of room for your
trai ler 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 339. •
Parking on a s•ope
Do not pork on a slope with a trailer. If it cannot be
avoided, do so only ofter doing the following:
When parking:
Apply the foot brake.
- Have someone p lace chocks under both the vehicle and
the trailer wheels.
With chocks in place, slow ly release the brakes until the
wheel chocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake.
