• USA models : If both the BRAKE warning light and the ABS
warning light come on at the same time, the rear wheels could lock up first under hard braking. Rear wheel brake lock-up can
cause loss of vehicle control and an accident . Have your vehicle
repaired immediately by your authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden , hard brake application .
• Canada models : If both the brake warning light ((DJ and the ABS
warning light
0 come on at the same time , the rear wheels could

& WARNING
• USA models : If the BRAKE warning light and the ABS warning
light come on together , the rear wheels could lock up first under
hard braking . Rear wheel lock-up can cause loss of vehicle control
and an accident . Have your vehicle repaired immediately by your
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models : If the brake warning light
{(j)) and the ABS
warning light
0 come on together , the rear wheels could lock up
first under hard braking . Rear wheel lock-up can cause loss of
vehicle control and an accident. Have your vehicle 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 does 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 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 situations . You must allow for increased braking
distances . The extra distance u sed up by fading brakes could lead
to an accident . •

Tire pressure monitoring system
Applies to veh ic les: with tir e pr essure monitor in g system
General notes
As an adde d safe ty feature, your vehicle has been equ ipped wit h a
tire pressure monitoring sys tem (TPMS) that i lluminates a low tire
pressure te llta le when one or more of your tires is significant ly
under-inflated . The TPMS only provides a low tire pressure warning
and does not reinflate your tires.
According ly, when the low tire pressure te llta le i llum inates, you
shou ld stop and check your tires as soon as possib le, and infla te
them to the proper pressure . Driv ing on a significantly under
inf lated tire causes the tire to overheat and can lead to tire failure.
Under -inflation a lso reduces fue l efficiency and tire tread life, and
may affect the vehicle 's hand ling and stopping ab ility .
0 Note
• Please note that the TPMS is not a substitute for proper tire
maintenance , and it is the driver's responsibility to maintain correct
