nal is also given .
A WARNING
-Always observe the warnings i n
c::> page 220, before opening the hood and
checking the bra ke fluid.
- Dr iving with low brake fluid is a safety haz­
ard. Stop the car and get profess ional assis­
tance .
-If the 1111 (USA models)/ . (Canada mod­
e ls) brake system indicato r light turns on to­
gethe r wi th the A BS and ESC indic ator
lights, the A BS/ ES C r egu lating function may
have fa iled . Functions that stabilize the ve ­
hicle are no longer availab le. T his co uld
cause the vehicle to swerve and increase the
risk of slid ing . Stop the car and get profes­
sional ass istance.
- If the brake warning/indicator light does
not go out after a few seconds and the park­
ing brake is released, or lights up wh ile you
are driving, the fluid level in the brake f luid
reservoir is too low . If yo u be lieve that i t is
safe to do so, proceed immediately at low
spee d to the ne arest a uthori zed Audi dealer
~

or qualified repair facility and have the
brake system inspected.
- Always keep in mind that after several brake
applications, you will need greater pressure
on the brake pedal to stop your vehicle. Do
not rely on strained brakes to respond with
maximum stopping power in critical situa­
tions. You must allow for increased braking
distances . The extra distance used up by
fading brakes could lead to an accident.

brake is automatically released and your vehicle
beg ins to move.
When stopping at a traffic signa l or stopping in
city traffic, the parking brake can be applied. The
vehicle does not have to be held with the foot­
brake . The parking brake eliminates the tendency
to creep w ith a dr ive range engaged. As soon as
you drive off as usual, the parking brake is re ­
leased a utomat ically and the vehicle starts to
move .
Starting on slopes
When starting on incl ines, the sta rting assist pre­
vents the vehicle from un intent iona lly rolling
back. The braking force of t he parking brake is
not released u nti l sufficient dr iv ing force has

'SI: .... .... Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
11-Keep the sw itch<®) pulled and depress the ac­
celerator. The parking brake stays applied and
prevents the vehicle from rolling backward .
11-You can release the switch© once you are su re
that you a re deve loping enough forwa rd mo­
mentum at the whee ls as you depress the ac­
celerator .
Depending on the weight of the rig (vehicle and
trailer) and the seve rity of the incline, you may
roll backwards as you start. You can prevent roll­
ing backwards by holding the parking brake
switch C®> pulled out and accelerating -just as
you would when starting on a hill with a conven­
tional hand brake.
Emergency braking
In the event that the conventional brake system
fails or locks.
11-In an emergency, pull the sw itch<®) and contin­
ue to pull it to s low your vehicle down with the
parking brake.
11-As soon as you release the switch © or acceler-
ate, the brak ing process stops.
If you pull the switch<®> and hold it above a
speed of about 5 mph (8 km/h), the emergency
braking function is in itiated. The vehicle is braked
at all four wheels by activating the hydrau lic
brake system . The brake performance is sim ilar
to making an emergency stop¢,& .
In order not to activate the emergency brak ing by
mistake, an audib le warning tone (bu zzer)
sounds when the sw itch(®) is pu lled . As soon as
the switch(®) is released, or the accelerator pedal
i s depressed, emergency braking stops .
A WARNING
Emergency braking should only be used in an
emergency, when the normal foot brake has
fai led or the brake pedal is obstructed. Using
t he parking brake to perform emergency
braking will slow your vehicle down as if you
D riving
had made a full brake applicat ion . The laws of
physics cannot be suspended even with ESC
and its associated components (ABS, ASR,
EDL). In corners and when road or weather
conditions are bad, a full brake application
can cause the vehicle to skid or the rear end to
b reak away -risking an acc ident.
Start/Stop system
Description
Applies to: vehicles with Start-Stop-System
The Start-Stop -System can help increase fuel
economy and reduce CO2 emissions.
In the Start-Stop-mode, the engine shuts off au­
tomatica lly when the vehicle is stopped, such as
at a traffic light . The ign ition remains switched
on during this stop phase. The eng ine will be au­
tomat ically restarted when needed.
The last Start-Stop-System setting (on/off using
the b utton
10 -I) will be restored when the igni­
t ion is turned on. The LED in the
10 ~1 button turns
on when the Start-Stop-System is switched off
manually .
Basic requirements for the Start-Stop mode
-The driver's door is closed.
- The driver' seat belt is latched .
- The hood is closed.
- The vehicle must have bee n driven faster than
2.5 mph (4 km/h) since the last stop.
- A trailer is not hitched to the vehicle .
A WARNING
-
-Never let the vehicle roll with the engine
switched off. You could lose contro l over the
veh icle. Th is can lead to a collision and seri­
ous injuries .
- The brake booster and the steering support
do not work while the engine is switched
off . More force is required to stop and to
steer the vehicle.
- To reduce the risk of injur ies, ma ke sure that
the Sta rt-Stop-System is turned off when
working in the engine compartment

Additional information
The engine will switch off in the P, D, N and S po­
sitions as well as in manual mode. In the P posi­
tion , the engine will also remain off if you take
your foot off the brake pedal. The eng ine starts
again when you select another selector lever po­
sition and take your foot off the brake pedal.
If you select the R position during a Stop phase,
the engine will start again.
Shift from D to P quickly to prevent the engine
from starting unintentionally when shifting
through R.
You can determine for yourself if the engine will
stop or not by reducing or increasing the amount
of force you use to press the brake pedal. For ex­
ample , if you only light ly press on the brake ped­
al in stop-and and-go traffic or when turning, the
engine will not switch off when the vehicle is sta-
86
tionary. As soon as you press the brake down
harder, the engine will switch off.
