_& WARNING
- Always pay attent ion to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your veh icle and other vehicles .
- For reasons of safety, cru ise control
should not be used in the city, in stop
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro
p lani ng) -risk of accident.
- Turn off the cruise control temporarily
when enter ing turn lanes, highway exit
lanes or in construction zones .
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration .
-If a brake system malfunction such as
overheating occurs when the cruise con
trol system is switched on, the braking
function in the system may be switched off. The other cruise control functions re

@ Tips
-Veh icles with manual transmiss ion: You
can attain the set speed only if the gear
that is currently engaged will allow it, or
if it does not tax the engine and allows i t
to run smoothly. Therefore shift into a
higher or lower gear in a timely manner.
- The brake lights illuminate as soon as
the brakes apply automatically.

When accelerating, the transmission will au
tomatically shift into the next gear before the
engine reaches its maximum RPM .
If you apply a light throttle when accelerat
ing, tiptronic will automatically shift from 1st
to 2nd gear to save fuel. If you apply a heavy
throttle, the transm iss ion will stay in 1st gear
until near maximum RPM is reached, or until
the driver shifts into 2nd gear .
If you take your foot off the accelerator pedal
when driving down a steep incline, tiptronic
will downshift from the selected gear into the
next lower gear until it reaches 1st gear,
based on road speed and engine RPM . Auto ·
matic downshifting is interrupted as soon as
you apply the throttle again .
(D Tips
-When you shift into the next lower gear,
the transmission will downshift only
when there is no possibility of over-rev
ving the engine.
- When the kick-down comes on, the
transmission will shift down to a lower
gear, depending on vehicle and engine
speeds .

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys
tem, anti -slip regulation (ASR) , e lectronic dif
ferential lock (EDL), dynamic steering* and electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain s ituations when you need

off ASR by press
i ng the button~~
page 186, fig. 159 or
~ page 186, fig. 160. Be sure to sw itch ASR
on again when you no longer need less trac
tion.
Anti-lock b ra king s ystem (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even d uring hard brak ing . Apply ste ady p res
sure to the brake pedal. Do not pump the ped
a l. A pulsing in the brake peda l indicates t hat
the system is he lping you to brake the vehicle .
Brake assist system
The brake assist system can decrease bra king
d istance. It increases braking power when the
d river presses the brake pedal quick ly in eme r
gency situations . You must press and hold the
brake peda l until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
d istance detected to the veh icle ahead is too
small.
Anti- slip regulati on (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Elect ronic diffe renti al lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-
Intellig ent technolog y 185

Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab il ize the s teer ing in crit ica l sit uat io ns.
Electronic interaxle differential lock* /
selective wheel torque control*
T he electronic i nteraxle differential lock (front
whee l dr ive) or the se lective whee l to rque
control (all-whee l dr ive) opera tes when dr iv
ing thro ugh curves. The front wheel on the in
side of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
cu rves . The applicable system may not acti
vate when dr iv ing in wet or snowy conditions.
A WARNING
- ESC, ABS , ASR, EDL dynam ic steering*
a nd the elect ronic interaxle differential
loc k* /se lective wheel torque control*
function cannot overcome the laws of
physics. This is especially important on
slippery or wet roads . If the systems be
gin acting to stabilize your vehicle, you
should immediately change yo ur speed
to match the road and traff ic conditions.
Do not let the increased safety provided
by these systems tempt you to take risks .
Doing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per
sonal injuries.
- Always adapt your speed to road, traffi c
and wea ther conditions. The risk of los
ing con tro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se
lective whee l torque control* function
cannot prevent collisions.

A WARNING ,~ ~
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner.
11-Always use lead-free gasoline q page 210,
Fuel supply .
"'" Never run the tank down a ll the way to
empty.
11-Never put too much motor oil in your en-
gine
q page 220, ~ Adding engine oil .
11-Never try to push -or tow-start your veh icle .
The catalytic converter is an efficient "clean up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere .
Drivin g and en vironm ent 193
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert
er and proper funct ion ing of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other mate rial wh ich can
cause a fir e.
- Do not apply additional undercoating or rustp roof ing on or near the exhaust
manifold, exhaust pipes, catalytic con
ve rter or heat shields. During driv ing, the
substance used for undercoating co uld
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fu el w il l already ser iously de
gra de the performance of the catalytic
c onverte r.
- Do not ex ceed t he cor rect eng ine oil level
qpage 220.
- Do not drive until the fue l tank becomes
comple tely empty. The engine co uld m is
fire . Unburned fuel could also get in to
the exhaust system and th is co uld cause
the catalytic converter to overheat .
- Do not turn off the ignition while the ve
hicle is moving.
- Do not continue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalytic converte r. T his
cou ld result in overheating of the con
verter, requir ing its replacement.

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 sealed and generally re
quires little attention.
The cooling system has been filled at the fac
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly
col-basedcoolant additive G 13 antifreeze with
anticorrosion add itives (SO% for USA mode ls;
60% for Canadian models). This mixture both
assures the necessary frost protection and protects metal components in the engine's
cooling system from corrosion and scaling. It
a lso raises the boiling point of the coolant .
Do not reduce the concentration of the coo l
ant in the summer by adding plain water .
The
p ro po rti on of c ool ant add it iv e mu st b e at
lea st 50 % but not mo re th an 60%
to main
tain antifree ze protection and cooling efficien
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i
cle heating and eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31° F(-3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
_& WARNING
Before yo u check anything in the engine
compartment, always read and heed all
WARNINGS
¢ &. in Working in the engine
compartment on page 215.
(]) Note
-
- Before winter sets in, have the coolant
checked to see if the coo lant additive in
your vehicle is s uffic ient to meet the cli
mate cond it ions . Th is is especially impor
tant if you live in a region where the w in
ter is extremely cold . If necessary, in- crease the p
roportion of coo lant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend us ing on ly coolant ad
d itive G12++ or G13 for your veh icle .
This coolant additive is availab le at au
thor ized Audi dealers. Other types of
ant ifreeze can s ignificantly reduce cor
rosion pro tection. The resulting cor ro
sion can cause a loss o f coolant and se
rious engine damage.
- Do not add any type of rad iator leak seal
ant to yo ur vehicle's engine coolant .
Adding radiator repair fl uid may adverse
ly affect the function and performance of
your cooling system and cou ld resu lt in
damage not covered by your New Veh icle

the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is unde r press ure and
can get ve ry hot. Reduce the risk of sca ld
