prehea ter connection
soc ket
T he engine preheater slow ly warms the engine coolant using a
heating element when the vehicle is parked. The included cable
4>
must be connected to a 120 Volt Ground Fault Circuit (GFI) protected
outlet that is protected from water (in your garage, for instance).
When the coo lant is preheated, the engine reaches its operating
temperature more qu ickly and will use less fuel and produce fewer
polluting emissions during the warm-up phase.
Preheat ing the engine can take up to 3 hours depending on the
temperature outside.
Conn ect ing th e engin e pr ehe ate r
• Only use the cable provided.
• All cables and connectors that are used must not be damaged

& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhau st fume s from the engine contain carbon monoxide, a color ­
less and odorless gas. Carbon monoxid e can be fatal if inhal ed.
• Never leave the engine idling unattended . An unattended
vehicle with a runn ing engine poses a danger of personal injury or
theft .
0 Note
• Avoid high engine speeds, fast acceleratio n or heavy engine loads
w hile the engine is still cold. This cou ld damage the eng ine .
• Th e engine c annot be sta rted by p ush ing or tow ing the veh icle .
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce e xhaust emissions,
do not let your vehicle stand and warm up . Be ready to dr ive off imme ­
diately after starting your vehicle. Maintain moderate speed unti l the
eng ine is comp letely warm . Remember, the engine performs best at
operat ing temperature. •
Stopping the engine
-Turn the ignition key to position @~poge 106, fi g. 107 .
& WARNING
• Nev er turn off the engine until the vehicle has come to a
c omplete stop.
• The brake booster and servotronic only work when the eng ine
i s running . With the ignition turned off , you have to apply more
force when steering or bra king. Since you cannot st eer and stop
normally , thi s can lead to accident s and serious injuries.
& WARNING (contin u ed )
• The radiator fan can continue to run for up to 10 minute s even
a fter you have turned off the engine and removed the ignition key.
The radi ator fan can also tur n on agai n if the engine coolant heats
up be cause of intense sunlight or heat build-up in the engine
compartment.
0 Note
Do not stop the engine immed iately after hard or extended driving.
Keep t he engine run ning for approximate ly two minutes to prevent
excessive hea t build-up. •

Trailer towingL _____________________________________________ _
ment 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
control the rig. Do not drive at the maximum permissible speed. Reduce your speed even more under unfavorable load, weather or
wind conditions -particularly when going downhill.
Reduce vehicle speed
immediately if the trailer shows the slightest
sign of swaying .
Do not try to stop the swaying by accelerating.
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 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.
Coolant temperature
The coolant temperature gauge~ page 9 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
-t-, pull 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 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
completely become familiar with the way your vehicle-trailer combi­
nation behaves and responds.
Backing up is difficult and requires practice. Backing up with a trailer
generally requires steering action opposite of 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~

engin e fro m ove rhea ting and i t pro tec ts th e engine from
f ree zin g in t he win ter .
The cooling system is sealed and genera lly requ ires little attention.
Th e cooling system has been filled at the factory wit h a permanent
coo lant which does not need to be c hanged. The coolant cons ists of a
mixt ure of water an d the manufacturer's glyco l-basedcoolant ad di­
tive G12 ++ a ntifree ze with a nticorros ion addit ives (50% fo r USA
mode ls; 60% for Canadian models). This mixture both ass ures the
nece ssary frost protec tion and p rotects meta l components in the
eng ine's cooling system from corrosion and scaling. It also raises the
boiling poin t of the co olant.
Do not red uce the co ncent ration of the coolant in the summer by
add ing p la in water.
The proportion of coolant additive must be at
least 50 % but not more than 60%
to ma inta in an tifreeze protectio n
and coo ling efficiency. If the coolant frost protect ion is too low, t he
coo lant co uld free ze and damage t he veh icle h eating and eng ine
