Driving and environment
(I] Tip s
The consumption estimates as pub lished by ENV IRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating .
-Avo id unnecessary accelerating and braking.
Vehicles use the most fue l when they a re accele rating. If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example when you see that the next traffic l ight is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed .
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approx imately three
qua rters of top speed, fuel consumption will be reduced by one half.
Never drive faster than the posted speed limit and weather condi­
tions permit.
a Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
-
Shut the engine off when yo u are not driving the vehicle.
- Do not warm up the vehic le by letting the eng ine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting for
trains to pass at rai lroad crossings, o r at traffic lights that have long
wa its on red . Turn ing the eng ine off for just 30-40 seconds saves
more fuel than is burned starting the engine again.
It takes a long t ime for the engine to warm up fully when it is running
at idle. Howeve r, wear and noxious emissions are espec ially high
when the eng ine is wa rm ing up. So you sho uld d rive away as soon as
you start the engine and avoid running at hig h rpms while the eng ine
is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which cou ld result in
overheat ing o r othe r damage to the vehicle or other p roperty. •
Regular maintenanc_e ____________ _
A badly tuned engine unnecessarily wastes a lot of fuel .
- Have your vehicle serviced at regular intervals .
By having yo ur vehicle regularly se rviced by an Audi dealer helps to
ensure that it runs properly and economically . T he condition of your
vehicle not only a ffects its safety and ability to ho ld its va lue, it a lso
affects
fu el con sumption .
Check your o il e ach tim e you fill you r tank.

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor ­
tation .
If you p lan to tow a t railer, p lease remember that the additional load
w ill affect durability, economy and performance.
Tr ailer towing not on ly p laces mo re s tress on the vehicle, it also calls
for more concentration from the driver.
For this reason, a lways follow the operating and dr iv ing inst ructions
prov ided and use common sense .
0 Note
If you are going to tow a trailer, you must activate the tra iler ope ra­
tion mode =>
page 170, "Towing a tra iler". •
Technical requirements
Trailer hitch
Use a we igh t-car rying h itch co nform ing to the gross tra iler we ig ht.
The h itch must be suitab le for your vehicle and trailer and must be
mou nted securely o n th e vehi cle's ch assi s at a
techni cally sound loc a­
tion . Use only a trailer hitch with a removab le ball mount. Always
check wit h the t railer h itch manufactu rer to make sure that yo u are
using the correct h itch .
Do not use a bumper hitch.
The h itch mus t be installed in such a way t hat it does not in terfe re
w ith t he impact-absorb ing bumper system. No modifications shou ld be made to t
he veh icle exha ust and bra ke systems. From t ime to
time, check that a ll hitch mounting bo lts rema in securely fastened.
W hen you are no t tow in g a tra ile r, remove the t railer hit ch ball
mount. This prevents the hitc h from caus ing damage should your
vehicle be str uck from behind=>& .
Trailer brakes
If your trail er is e quipped w ith a b raking system, che ck to be s ure t hat
it conforms to all regulations.
T he tra ile r hydrau lic brake system m ust not be directly connected to
t he vehicle's hyd raulic b rake sys tem .
Safety chains
Always use safety chains between your veh icle and t he tra ile r.
Trailer lights
Trailer lights must meet all regulations. Be sure to check w ith your
Audi de aler fo r corr ec t wir ing , sw itches and re lays.
Mirrors
If you are unab le to see t he t raff ic be hind you using t he regular
outs ide mirrors, then you
must install extended mi rrors. It is impor­
t an t th at yo u
always ha ve clear vi sion to the re ar.
& WARNING
After removing the trailer hitch, do not store it in your vehicle. In
case of sudden braking , the hitch could fly forward and inju re you
or your passengers. •

Operating instructions
Max imum tr aile r weight
A trai ler for your vehicle is lim ited to a typical class 1 or class 2 trailer.
Trail er lo ad di stribut ion
Be sure the load in the t ra iler is held secu rely in place to prevent it
from shift ing forward, backward or sideways.
N ev er a llow a pa ssenge r to ride in a traile r=>
& in "Driving instr uc­
tions".
Eng ine c ooling s ystem
Towing a trailer makes the eng ine work harder. It is important that
the cooling system 's performance is up to the addi tional load. Make
sure that the cooling system has enough fluid.
Tire pre ssur e
When towing a tra iler, inflate the tires of your veh icle to the co ld tire
pressu re listed under "Full load" on the label located on the d river's
side 8 -pillar (visible when the door is open) . Inflate traile r tires to
t rai ler and tire manufacture rs' specificat io n s.
Light s
The headl ight sett ings shou ld be checked with the tr ailer attached
before driving off. Check to make sure both vehicle and trailer lights
are working properly .
Safety chain s
Be sure traile r safety cha ins are p roperly connected from the trai ler
to the hitch on the vehicle. Leave enough slack in the chains to perm it
tu rning corners. When you install sa fe ty cha ins, make s ure they will
not drag on the road when you are driving.
T he chains should cross under the trai ler tongue to prevent it from
dropping in case of separation from the h itch .

Driving instructions
Driving with a trailer always requires e xtra care and
consideration .
To obtain the best possible handling of vehic le and trailer,
please note the following:
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other veh icles .
- Observe speed limits .
- Do not dr ive at the maximum permissible speed.
- Always apply brakes early .
- Monitor the temperature gauge .
Weight distribut ion
T owing a loaded tra iler w ith an empty car results in a highly unstable
distribution of we ight . If this cannot be avoided, d rive at very low
speeds only to avoid the risk of losing steering control.
A "balanced" r ig is easier to operate and control. This means that the
t ow ve hicle sho uld be loaded to the exte nt poss ible and permissib le,
wh ile keeping the tra iler as light as poss ible under the circumstances.
Whenever poss ible, tra nsfer some cargo to the l uggage compart ­
ment of the tow vehicle while observing tongue load requirements
and vehicle load ing considerations .

Trailer towing
"---------------------------------------------------
Speed
T he higher the speed, the more difficult it becomes for the driver to
control the rig. Do not dr ive at the max imum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icu larly when go ing downhill.
Reduce vehicle speed
immediately if the tra iler shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for veh icles towing
trailers are lower than for regu lar vehicles.
Always apply brakes early. When driv ing dow nhill, shift in to a lower
gear to use the eng ine braking effect to slow the veh icle. Use of the
bra kes alone can cause them to overheat and fail.
Coolant temperature
Th e 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 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 m inutes 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 tow ing a trailer because of the
additiona l weight and different weight distribution. Safety, perfor- mance and economy will greatly depend on how carefully you load
your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopp ing and
backing up in an area away from traffic. Keep practicing until you have
become completely familiar with the way your vehicle-t railer comb i­
nation behaves and responds.
Backing up is difficult and requires practice. Backing up with a trailer
generally requires steering action oppos ite to that when backing up
your vehicle without a trai ler.
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
enoug h room to pass. After passing, allow plenty of room for your
trai ler before changing lanes again.
Avoid jerky sta rts, sharp tur ns or rapid lane changes.
W Tips
• Do not tow a trailer during the break-in per iod of your veh icle.
• If you tow a trai ler, your Audi may require more frequent mainte­
nance due to the extra load
~ page 346. •
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 p lace 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 whee ls towards the curb .
- Apply the parking brake.
- Move the selector lever to
P.
When restarting after parking:
- Apply the foot brake.
- Start the eng ine .
- M ove the selector lever to
D.
-Release the parking brake and slowly pu ll out and away
from the wheel chocks .
- Stop and have someone retrieve the wheel chocks .
[ i ) Tips
If you move the se lector lever of the automat ic t ransm ission to P
before applying the parking brake and before blocking the whee ls,
yo u may have to use mo re force later to move the leve r out of t he
P
position. •
