could lock up first under hard braking . Lock-up of the rear whee l
brakes can cause loss of vehicle control and an accident. Have your
vehicle repaired immediat ely by your authorized Audi dealer or a
qualified work shop. Drive slowly and avoid sudden, hard brake
application
• If the brake warn ing/indicator light does not go out after a few
se cond s and the parking brake rel eased, or light s up while you are
driving , the fluid level in the brake fluid reservoir is too low. If you
believe that it i s safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified workshop and
have the brake system in spe cted.
• Please be very careful and always keep
in mind that after
s everal brake application s, you will need greater pressure on the
brake pedal to stop your vehicle. Consequently, you must allow
for increased braking distances. Trying to brake a s quickly a s usual
could lead to an accident. •

Stopping on an incline
- Always
hold t he vehicle with the footbrake or parking
b rake in order to preve nt "ro llback "=> & . Do not try to
p reve nt t he v ehicle from ro lli ng back by re vving th e e ngine
whi le it is in gea r.
Starting on a hill
- Apply the hand bra ke fi rmly.
- With t he eng ine in gear , gra dually acce lerate a nd release
the hand bra ke.
T he eng ine c an only be started with the selector leve r in P or N
=>
page 107 . At low amb ient temperatures (14 °F /-10 °(), it i s only
possible to start the engine with the selector lever in P.
W hen pa rking on leve l grou nd , it is suff ic ient to p lace the se lector
lever in P. On a steeply sloping road, you shou ld f irst app ly the
par king brake firmly and then p lace t he selecto r leve r in P. T his way,
you do not overload the paw l mechanism and it is easier to move the
selector lever out of P.
& WARNING
• Never leave your vehicle with the engine running while in ge ar.
If you must lea ve your vehicle with the engine running, set the
parking brake and engage the park lo ck .
• When the eng ine i s running and the transmi ssio n is in gear (D ,
Sor R ) or in "tiptronic " mode, it is ess ential that you stop the
v ehicle with the footbrake. When idling , the transmiss ion of
power doe s not stop completely -the vehicle "creeps".
• Do not a ccelerate when you change the selector leve r position
with th e vehicle stationary and the engine runn ing -risk of an acci­
dent!
• Never place the selector lever in the R or N position wh ile the
v ehicle is moving -risk of a n accident!
& WARNING (continued )
• If you have to bring your vehicle to a stop while on an incline ,
keep the foot brake depressed all the way down so that the vehicle
does not start to roll backward. You should never hold the veh icle
using the clutch if you are going to b e stopped on an incline. If you
do , the clutch will start to slip when it o verheats c aused by the
c onstant overload . Thi s is danger ous be cau se if the vehicl e start s
to roll backward , you could cause an accident. If the clutch should
s tart to slip, you will fee l the vehicle "jerk " and the selector lever
d isplay w ill start blinking.
• Befor e driving down a st eep slope, reduc e your speed and shift
i nto a lower gear w ith "tipt ronic ".
• Do not ride the brakes or apply the brake pedal too often or too
long . Constant b raking causes the brakes to overheat and
s ub stantially reduces braking performan ce, in creases braking
d istance or causes complete failure of the b rake system . •

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieva l after an accident or crash event. ED R's are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED R's that were installed 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 w ith
a number of electronic control modu les for various vehicle systems
such as, for example, engine function, emission control, as well as for
the airbags and safety belts.
T hese electronic contro l modules also record vehicle-re lated data
during normal vehicle operation for diagnostic and repair purposes .
Th e recording capacity of the e lectronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally 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 well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment.
Electronic Stabilization Program
(ESP)
General
The Electronic Stability Program increases driving
stability .
With ESP, contro l over the vehicle is increased in situations when the
vehicle is close to the limits of grip, such as dur ing accelerat ion and in
curves. ESP reduces the risk of sk idding and improves vehicle stability
unde r all road conditions.
It operates at all speeds.
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDS) and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
How ESP works
The ESP control unit processes the following data from high-sensitive
sensors: the rotationa l speed of the vehicle about its vertical axis,
fore-and -aft and lateral acceleration forces, brake pressure and
steering angle .
Us ing stee ring ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
actual vehicle behavior. If the two do not match, for example when
the vehicle beg ins to skid, ESP brakes the appropriate whee l auto­
matically.
The vehicle is stabilized aga in by the forces act ing on the whee l
during braking. With an oversteering veh icle (tendency for the rear
end to skid out of the curve), the brake app lication is mainly at the
front wheel on the outside of the curve, with an understeering vehicle
(tendency to run wide in the curve) at the rear wheel on the insid e of
the curve or additionally at the other wheels as needed. This brake
application is accompanied by noises. _,
