LATCH Lower
anchorages and tethers
for children
Child Restraint System anchors and how
are they related to child safety
To provide a s imp ler and more prac ticable way
to attach the chi ld restraint on the vehicle
seat, Federa l reg ulations require specia l lower
anchorages in vehicles and devices on new
child restraints to attach to the vehicle ancho­
rages.
The combination of the tether anchorages and
the lower anchorages is now generally called
the
LATCH system for " Lower Anchorages and
T ethers for Children."
F orward-facing child rest raints manufactured
after September 1, 1999, are required by U .S .
federal regulations to comply with new child head movement performance requirements. T
hese new performance req uirements make a
tethe r necessary on most new child seats.
Installing a c hild restra int tha t requires a top
tether wi thou t one can seriously impa ir the
performance of the chi ld restra int and its abil ­
ity to protect the child in a collision . Insta lling
a chi ld restraint that req uires a top tether
without the top tether may be a violat ion of
state law.
Child restraint manufacturers offer LA TCH
lower anchorages on their child seats w ith
hook-on or push-on connectors attached to
adjustable straps.
In addition to the LATCH lower anchorages,
these chi ld restraint systems usua lly require
the use of tether straps to he lp keep the chi ld
restraint firmly in place.
A WARNING ,.__ -
Improper installat ion of child restra ints
will increase the r isk of injury and death in
a crash.
- Always follow the instructions provided
by the manufacture r of the child re­
straint you intend to install in your ve hi­
cle.
- Never install a chi ld restrai nt without a
p roperly attached top tether strap if the
child res tra int m anufa cture r's instruc­
tions require the top tether st rap to be
used .
- I mp roper use of child restraint LA TC H
lowe r ancho rage poin ts can lead to injury
in a co llision. The LATCH lower anchorage
points are designed to withstand on ly
those loads imposed by correctly fitted
child restraints.
- Never mo unt two child restraint systems
on one LATCH lower anchorage point.
- Never secure or attach any luggage or
other item to the LATCH lower anchorag­
es.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 189
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
JjJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface. If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds.
Always adjust your speed and driving style to
road, traffic and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by usin g the driver 's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti- lock brake system (ABS), brake assist sys -
tem, anti-slip regu lation (ASR), electronic

differential lock (EDL), dynamic steering* and
selective whee l torque control. ESC is switch­
ed on all the t ime. In certa in situations when
you need less traction, you can switch off ASR
by pressing the button
[ill c> page 191,
fig. 180. Be sure to switch ASR on again when
you no longe r need less traction .
Anti-loc k br ak ing system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even during hard brak ing. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal ind icates that
the system is he lp ing you to b rake the vehicle.
B rake as sist sys tem
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quick ly in emer ­
gency situations. You must p ress and hold the
b rake pedal until the situation is over. I n
vehicles w ith adaptive cru ise cont rol*, the
b rake assist system is more sens it ive if the
d istance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR)
ASR reduces engi ne power when the d rive
wheels begin to spin and ad apts the fo rce to
the road condit ions. This makes i t easier to
start, accelerate and drive up hills .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the d rive powe r to the other d rive
wheel o r whee ls if the vehi cle is equipped wi th
a ll-w hee l drive* . This function is available up
to about 75 mph (120 km/h).
I n extreme cases, ED L automat ica lly swit ches
off to help keep the brake o n the braked whee l
from overheating . EDL wi ll switch on again au­
tomatically when conditions have returned to
norma l.
Dynamic steering*
On vehi cles w ith dy namic stee ring*, ESC helps
stabilize the steering i n critical s ituations.
Selective wheel torque control
T he sele ctive whee l torq ue con trol ope rates
when driving through c urves . The front whee l
on the inside of th e curve o r both wheels on
the inside of the curve are braked selectively
as needed. This minimizes sliding in the front
whee ls and allows for more precise driving
t hr ough curves. The appl icable system may
not act ivate when dr iv ing in wet or snowy con­
ditions .
,&. WARNING
-ESC, ABS, ASR, EDL, dy namic steeri ng*
and the select ive wheel torq ue con trol
c a nnot ove rcome the laws of physics.
T his is especially important on slippery
or wet roads.
If the systems begin acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traffic conditions. Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and ser ious per­
sonal injur ies.
- Always adapt your speed to road, traffic
and wea ther conditions. The risk of los­
ing con trol of t he vehicle increases when
d riving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, ASR, EDL, dynam ic steering* and
the selective wheel torque contro l can­
not prevent collisions .
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow .
The drive wheels can spin eve n w ith
these assistan ce systems that cannot al­
ways he lp to re duce the risk of loss of ve ­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheels are equipped with identi­
cal tires. D iffe ren t tire si zes can lead to a
reduction in engine power.

Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and

tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.

The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see
c::;, page 208.
Your vehicle fue l tank has an on board refuel­
li ng vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never

to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Fai lure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filter neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a ce llular telephone while re­
fue ling. Th e electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fueling.
If in exceptional circumstan ces
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open flame any­
where in or near your veh icle when refu­
eling or filling a portable fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable

fuel container in your vehicle. The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for example, in the lugga ge compart­
ment, or on the tr unk). Static electrici­
ty can bui ld up while fi lling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the fi ller nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. Th is w ill
help prevent static electricity from dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable .
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852 -86) .
(D Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint.
~ For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the first
time, the tank is full. Do not try to add
more fue l because fuel may spill out . In
add it ion, the expans ion space in the fuel
tank will be fi lled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
Fuel supply and filling your fuel tank 211
@ Tips
-Running your engine while refue lling
may cause vapors to escape or even
cause fuel to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not ind icate the correct fuel
level after refuell ing .
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from

by your authorized Audi dealer. It is not
enough merely to add coolant .
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
&_ WARNING
-
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in

-To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system
or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire .
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle 's engine coolant. Add-
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited

Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS <=>.&. in Working in the engine compart­
ment on page 213.
"'Turn off the engine.
"'Let the engine cool down .
"' Place a thick rag over the coolant expansion
tank
<=> page 220, fig. 191 and carefully
twist the cap counter-clockwise <=>_& .
"'Add coolant mixed in the correct ratio
<=> page 220, Coolant.
"'Twist the cap on again tightly.
Replacement engine coolant must conform to
exact specifications <=>
page 220, Coolant.
We recommend using only coolant addi-
tive G12++, G13 or in an emergency G12+. Do
not use a different additive. In an emergency
use plain water until you can get the correct
additive 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 cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex -
cess coolant will be forced out through the ..,.
