W eig ht d is tri buti on
Towing a loaded tra iler wit h 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 avo id the risk of losing 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
compar tment of the tow veh icle whi le observi ng tongue load
requirements and vehicle loading considerations.
Speed
T he higher the speed, the more difficu lt 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 conditions -part icularly when going dow nh ill.
Reduce vehicle speed
immedi ately if the trailer shows the slightest
sign of swaying.
Do not tr y to stop the s waying by a cceler ating .
Observe speed limits . In some areas speeds for veh ic les towi ng
trai lers are lower than for regular vehicles.
Always app ly brakes early. When driving downhi ll, 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 la nt tempe ra tu re
The coola nt temperature gauge => page 13 must be observed care ­
ful ly. 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 te mperature 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 p rop erl y res trained in a mo ving vehicl e is at a much
gre ate r risk in an accident. Never let an yone rid e in your car who
is not p rop erl y wear ing the re stra int s pro vided b y Aud i. •
Trailer towing tips
Important to know
Your vehicle handles differently when towing a tra iler because of
the additional weight and weight distribution. Safety, performance
and economy wi ll great ly depend on how carefu lly you load your
trai ler and operate your rig.
Before you actual ly tow your tra iler, practice turning, stoppi ng and
backing up in an area away from traffic. Keep practicing unti l you
have comp letely become familiar with the way yo ur vehicle -trailer
combination behaves and responds .
Backing up is difficu lt and requires practice. Backing up with a
trai ler genera lly requ ires steering action oppos ite of that when
backing up your vehic le without a trailer.
Mainta in a greater distance between you r vehic le 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 normal
t urning radius .
When passing, remember that you cannot accelerate as fast as you nor mally wou ld because of t he added load . Make sure yo u have
enough room to pass. After passing, al low plenty of room for your
trai ler before changing lanes again .
Avo id jerky starts, sharp turns or rapid lane changes.

Traile r to win g -______________ _,..,_l'flllll
[ 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 extra load
=> page 346 . •
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 arkin g:
-Apply the foot brake.
- Have someone place chocks under both the veh ic le and
the trailer wheels .
- Wit h chocks in p lace, s lowly 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 re starting aft er p arking:
- Start the e ngine .
- Shift transmission into gear.
- Re lease the parking brake and slowly pull out and away
from the wheel blocks.
- Stop and have someone retrieve the whee l blocks.

For example, a charging current of 4.5 amps would be used on a
battery rated at 45 Ah. Rated capacity of the battery in your vehicle
is listed on the battery housing .
The battery caps should
not be opened when charging a battery.
& WARNING
Charging a battery can be dangerous.
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery.
• Never charge a frozen battery . It may explode because of gas
trapped in the ice. Allow a frozen battery to thaw out first.
• Do not reuse batteries which were frozen. The battery housing
may have cracked and weakened when the battery froze.
• Charge the battery in a well ventilated area. Keep away from
open flame or electrical spark. Do not smoke. Hydrogen gas gener ­
ated by the battery is explosive.
• To reduce the danger of explosion, never connect or disconnect
charger cables while the charger is operating.
• Fast charging a battery is dangerous and should only be
attempted by a competent technician with the proper equipment.
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid.
0 Note

The tire pressure label on your Audi lists the recommended cold tire
inf lation pressures for the new, original equipmen t tires that were
on your vehic le at the time it was manufactured . For the location of
the
labe l=> page 297, fig. 217 .
Most tires lose a ir natural ly over time. They can a lso lose some air if
you drive over a potho le or hit a curb wh ile parking. It is usually not
possible to see whether the radial t ires used today are under inflated
just by looking at them.
Therefore, be su re to check tire pressures at least once a month and
always before going on a long trip . Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you wou ld not cons ider to be
" long ."
See => page 301, "Tires and vehicle load limits" for more
important i nformation .
A lways use an accurat e tire pressure gaug e when checking and
adjusting inflat ion pressures. Check a ll of the tires and be sure not
to forget the spare tire . If the pressure in any tire is too high when
the t ire is "cold," let air o ut of the t ire slowly with the edge of the tire
gauge and keep check ing the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you p lan to do .
I f the pressure in any tire is too low, note the difference between the
pressure in the co ld tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) fo r the t ires on your veh ic le as listed on
the on your vehicle and in this manual and the kind of driving you pl an to do .
Never exceed the m aximum inflation pressure li sted on the tire
s idewall for an y re ason .
Remem ber that the vehic le manufacturer, not t he tire manufacturer,
determines the correct tire pressure for the tires on your vehicle .
I t is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the t ire pressure label
located either on driver 's side B -pillar or inside the fuel fi ller flap . •
Turn the va lve stem cap counter -clockwise to remove it from the
t ire valve .
• Place the air pressure gauge on the valve.
• The tire pressures should only be checked and adjusted when
the tires are cold. The s lightly raised pressures of warm tires must
not be reduced.
• Adjust the tire pressure to the load you are carrying.
• Reinstal l the va lve stem cap on the valve .
When should I check the tire pressure?
The correct tire pressure is especially important at high spe eds . The
pressure should the refore be checked at least once a mo nth and
a lways before starting a journey. Do not forget to check the tire pres ­
sure for the spare whee l
=> page 317.
Wh en should I adjust th e tir e pre ssur es?
Adjust t he tire pressure to the load you are carry ing . After changing
a wheel
o r replacing whee ls you have to ad just the tire pressures on
a ll whee ls . In addition, on vehicles w ith tire pressure monito ring
system* you must then store the new tire pressures in the system
=> page 45.
& WARNING
Incorrect tire pre ssure s and /or underinflation can lead sudden tire
f ai lure , loss of control , collision , seri ous per sonal injury or even
death.
• When the w arning symbol
(l) appe ars in the in strument
clu ster , stop and inspect the tire s.
• Incorrect t ire pres sure and /or underinflat ion can cause
increa sed tire wear and can affect the handling of the vehicle and
s topping ability.
• Incorrect tire pres sures and /or underinflation can also lead to
s udden tire fa ilure , inc luding a blowout and sudden defl ation ,
cau sing los s of vehicle control .
