Trailer load distribution Be sure the load in the trailer is held securely
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ .&. in Driving instructions on page 212.
Engine cooling system
Towing a trailer makes the engine work hard
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac
turers' specifications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains Be sure trailer safety chains are properly con
nected from the trailer to the hitch on the ve
hicle . Leave enough slack in the chains to per
mit 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 .
Adjusting the Audi drive select Make sure the vehicle is on a level surface
be
fore
hitching up the trailer and before adjust
ing the tongue weight. The vehicle must be in
auto or comfort driving mode and not raised
¢page 108, ~CD .
Make sure that the vehicle is lowered. In Info
tainment, select:
ICARI function button> low
er control button .
Trailer towing 211
If you must drive under poor road conditions,
you can raise the vehicle
after coupling the
trailer or
after adjusting the tongue weight
¢ page 110.
@ Note
- Changes in temperature or load can af
fect the height of the vehicle.
- Always select auto or comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following:
.,. Do not tow a loaded trailer when your car it
self is not loaded .
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits.
.,. Do not drive at the maximum permissible
speed .
.,. Always apply brakes early .
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car re
sults in a highly 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 con
trol. This means that the tow vehicle should be loaded to the extent possible and permissi
ble, while keeping the trailer as light as possi
ble under the circumstances . Whenever possi
ble , transfer some cargo to the luggage com
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be
comes for the driver to control the rig. Do not .,.

Engine oil consumption
The e ngine in your vehicle dep ends on an ade
quate amount of oil to lubricate and cool all
of its m oving parts .
In order to provide effective l ubrication and
cooling of internal engine components, all in
ternal combustion eng ines consume a certain
amo unt of o il. O il cons umption varies from
engine to eng ine and may c hange significant ly
over the li fe o f the eng ine . T yp ica lly, eng ines
with a specified break -in per io d (see
¢
page 205) cons ume more oi l during the
b reak-in period than they consume after oil
consumption has stabilized.
Unde r norma l conditions, the ra te of oil con
sumption depends on the quality and viscosity
of the oi l, the RPM (revo lutions per minute) at
which the eng ine is operated, the ambient
temperature and road condit ions. Further fac
tors are t he amount of oil d ilution from wate r
condensation or fuel residue and the ox ida
t ion level of the o il. As any engine is subject to
wear as mileage bu ilds up, the o il consump

236 Check ing and filling
@ For the sake of the environment
- Before changing your oil , first make sure
you know where you can properly dispose
of the used oil.
- Always dispose of used engine oil proper
l y. Do not dump it on garden soi l, wood
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro tects the engine from freezing in the winter.
The cooling system is sea led and generally re
qu ires little attention .
The cooling system has been filled at the fac
tory with a pe rmanent coolant which does not
need to be c hanged. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer 's glycol-based coo lant add i-
tive G l3 antifreeze with ant icorrosion addi
tives (50% for USA models ; 60% for Canadian
mod els). This mixture both assures the nec es
sary frost protection and protects metal com ponents in the engine's cooling sys tem from
corrosion and scaling . It a lso raises the boil
ing point of the coolant .
Do not red uce the concentration of the coo l
ant in the summer by adding plain water.
The
proportion of coolant add it ive mu st be at
l e a st 50 % but not more than 60 %
to main
tain antifreeze protection and cooling efficien
cy . If the coolant frost prote ct ion is too low,
the coo lant cou ld freeze and damage the veh i
cle hea ting and eng ine cooling system.
For yea r-round d riving, antifreeze is added at
the fac to ry for temperatures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada. If
you must add coolant, use a mixture o f wa
ter and coolant additive . Mixing the coo lant
additive with distilled water is recommended.
A WARNING
-
Before you c heck anything in the engine
compartment, always read and heed a ll
WAR NINGS
c::, & in Working in the engine
compartment on page 228.
(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli mate conditions . This is especia lly impor
tant if you live in a reg ion where the win
ter is ex treme ly cold. If ne cessa ry, i n
crease the pr opo rtion of coo lant add itive
t o 60%.
- Whe n adding coolant additive to yo ur
c ooling sys tem, remembe r:
- We recommend using on ly coolant ad
d itive Gl2++ or Gl3 for your vehicle .
This coolant additive is availab le at au
thor ized Audi dealers . Other types of
ant ifreeze can s ignificant ly reduce cor
rosion protection. The resulti ng cor ro
sion can ca use a loss o f coolan t and se
rio us engine damage.
- Do not add any type of rad iator leak seal
a nt to yo ur vehicle 's engine coolant.
Add ing radiator repai r fl ui d may adverse
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not covered by yo ur New Vehicle

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 204 Eng ine compartme nt: cover o n the coolant
expansion tank
Before you check anything in the engine com
partment,
a lway s read and he ed all WARN
INGS ¢ & in Working in the engine compart
ment on page 228.
Park your vehicle on a level surface.
~ Switch off the ignition.
~ Read the engine coolant leve l from the cool
ant expansion tank¢
fig. 204, ¢ page 230.
With a cold engine, the coolant level should
be between the "min" and "max" markings.
When the engine is warm, the level may be sl ightly above the ''max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration ¢
page 230 .
To obtain an accurate reading, the engine
must be switched off.
The expansio n tank in your vehicle is equipped
with an electric coolant level sensor.
When t he coo lant level is too low, the warning
light in the Auto-Check System¢
page 15 will
illuminate unti l yo u add coolant and the level
has been restored to normal. Even thoug h
there is an electric coolant level sensor, we
still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool-
Checkin g and fillin g 237
ing system shou ld be inspected immediately
by your authorized Audi dealer . It is not
eno ugh merely to add coo lant .
In a
s ealed system, losses can occu r on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Red uce the risk of scald
ing from hot coolant by follow ing these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id a nd steam by cover ing the
cap with a la rge, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap
p lyi ng lig ht, dow nward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti
freeze o r coolan t on the exhaust system
or ho t engine parts. Und er certa in cond i

• Make sure that the fluid level rema ins sta-
ble. Add more coolant if necessary.
• Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 236, Coolant.
We recommend using only coolant additive
G12++, G13 or in an emergency G12+ . Do not
use a different additive . In an emergency use
p la in water unt il you can get the correct add i
tive and can restore the correct ratio. This
should be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add co ld antifreeze
and cold water only when the engine is co ld.
Always use
new eng ine coolant when refilling .
Do not fi ll coolant above the "MAX" mark. Ex
cess coolant will be forced out through the pressure relief valve in the cap when the en
g ine becomes hot .
A WARNING
- T he coo ling system is under p ressure and
can get very hot. Reduce the risk of
scalding from ho t coolant by following
these steps.
-Turn off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from escaping flu id and steam by cover ing
the cap with a large, thick rag.
- T urn the cap slowly and very carefully
in a counter-clockwise d irect ion while
apply ing light, downward pressure on
the top of the cap.
- To avo id being burned, do not sp ill an
tifreeze or coolant on the exhaust sys
tem or hot engine parts . Under certa in cond
it ions, the ethylene g lycol in en
gine coolant can catch fire.
- Antifreeze is poisonous . A lways store an
tifreeze in its origina l container and well
out of the reach of children.
- If you dra in the coo lant, it must be
caught and safely stored in a proper con
tainer clearly marked "po ison".
@ Note
- Do not add coolant if the expansion tank
is empty. Air co uld enter the cooling sys
