& WARNING
• USA models: If the BRAKE warning light and the warning
light come on together, the rear wheels could lock up first under
hard braking. Rear wheel lock-up can cause lo ss of vehicle control
and an accident . Have your vehicle repaired immediately by your
authorized Audi dealer or a qualified work shop . Drive slowly and
avoid sudden, hard brake applications.
• Canada model s: If the brake warning light (CD) and the ABS

fir st under hard braking . R ear wheel lock -up can cause lo ss of
vehicle control and an accident. Have your veh icle repaired imme­
diately by your authorized Audi dealer or a qualified workshop.
Drive slowly and avoid sudden, hard brake applications .
• If the brake warning /indicator light doe s not go out after a few
seconds and the parking brake released, or lights up while you are
driving , the fluid level in the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified repair facility
and have the brake sy stem 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 re spond with maximum stopping
power in critical situations. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident . •

(I] Tips
For s afety reasons, t he pa rking br ake is r eleased automatically only
when the driver 's safety belt is engaged in the buck le .•
Starting off with a trailer
To prevent rolling back unintenti onally on an incline, do
the following :
-Keep the switch pu lled and depress the accelerator. T he
parking brake stays a pp lied and prevents the vehic le from
ro lling backward.
- You can re lease the switch once you are sure tha t you are
deve lopi ng enough driving force at t he wheels by
depressing the accelerator .
Depending on the we ight of the rig (vehicle and trailer) and the
sever ity o f the in cl ine, you may roll backwa rds as you start . You can
prevent roll ing backwards by holding the park ing brake sw itch pulled
out and accele ra ting -just as you wou ld when starting on a hill wi th a
conventional hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks .
-In an emergen cy , pull t he sw itch and contin ue to pull it to
slow your vehic le down with t he p arking brake.
- As soon as you re lease t he swi tch or acce lerate, the
bra king process s tops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking fu nction is initiated . The vehicle is braked at all four wheels by activating the
hydraulic brake system.
Th e b rake pe rformance is s imila r to mak ing an eme rge ncy sto p .=>
&
In order not to act ivate the emergency brak ing by m istake, an audib le
warning tone (buzzer) sounds when the switch is pulled. As soon as
t he swi tch is re leased, or the acce lerator pedal is dep ressed , emer ­
gency braking stops .
& WARNING
Emergency braking should only be used in an eme rgency , when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle down as if you had made a full brake application . The
laws of physics cannot be suspended e ven with ESP and its associ ·
at ed components (ABS, ASR, EDS ). 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 break away· ri sking an accid ent. •
Driver messages in the instrument cluster
Warning Vehicle incline i s excessive
Th is message appears when the parking brake is applied on an incline
t ha t exceeds abo ut 3 0%.
I n th is case the braking power of the parking brake may
not be
adequate
to prevent the vehicle from rolling unintentionally.
Pl ease release parking brak e
Please note that for safety reasons the pa rking brake is re leased auto ­
matically on ly if the d river's seat be lt is fully engaged i n the buck le .
To relea se the parking brake pre ss the brake pedal
Th is dr iver message appears when the switch to release the parking
