T he warning/indicator light (E lectronic Power Control) illumi -
nates when you turn o n the ignition as a function chec k.
[ i ] Tips
If this warning/indicato r light ill uminates while you are driving, then
there is a malfunct ion in the engine e lectron ics . Have the malfunct ion
co rrected as soon as possib le by yo ur autho rized Audi dealer or qua l­
ified workshop .•

Glow plug system
The control light illuminates when the glow plug system
is active.
If the indicato r ligh t illum inates, the g low p lug system is active .
You should start the eng ine immed iate ly after the ind icator light
switches off. The ind icator ligh t only illumina tes for approximately 1
second if the engine is warm or if the outside temperature is above 46
2F (8 2C).
(I] Tips
• If the glow plug indicator light illuminates while driving, there is
an engine control malfunction. The engine should be checked imme­
diately .
• If the indicator light does not ill uminate at all when switching the
ign ition on, the re may be a ma lfunction in the glow plug system. The
engine should be checked .•
Electronic stabilization program (ESP) ~ / t:.
This warning/indicator light monitors the electronic
stabilization program .
If the indicator lamp blinks w hile driving, the ESP or ASR (Anti-Slip
Regulation) is actively regulat ing .
If the ~ indicator lamp illuminates, the system has switched the ESP
off. In this case , you ca n swi tch t he ignition off and then on to swi tch
the ESP on again. The system is functioning completely when the
ind icator lamp sw itches off.
If the ind icator lamp illuminates, the ESP was switc hed off w ith the
I~ OFF! button .
ESP/ ABS fault ! See own er' s manual
If the • indicator lamp and the ~ ABS indicator lamp illuminate and
the d river message appea rs, the ABS or e lectronic differentia l lock is
ma lfunction ing . This also interrupts the ESP . The brakes still funct ion
w ith their normal power, but ABS is not act ive .
Dr ive to your author ized A udi deale r immediately to have the
malfunction corrected.

& WARNING
• If the .. (USA models )/ ...,. (Canada models ) wa rning light
does not go out , or if it comes on while driving, the ABS system is
not working properly. The vehicle can then be stopped only with
the standard brakes (without ABS ). You will not have the p rotec­
tion ABS provides. Contact your authorized Audi dealer a s soon as
pos sible.
• USA models : If the BRAKE warning light and the M, warning
light come on together, the rear wheels could lock up fir st under
hard braking. Rea r wheel lock-up can cause loss of vehicle cont rol
and an accident . Have your vehicle repaired immediately by your
autho rized Audi dealer or a qualified work shop. Dri ve slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light 0 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 imme­
diately by you r authorized Audi dealer or a qualified wo rkshop.
Drive slowly and avoid sudden , hard brake applications .•

& WARNING (continued)
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 used up by fading brakes could lead
to an accident. •

& WARNING
• Always pay attention to traffic even when the cruise control is
switched on. You are always responsible for your speed and the
di stan ce between your vehicle and other vehicle s.
• For safety reasons , the cruise control should not be used in the
city, in stop-and -go traffic, on twisting roads and when road
conditions are poor (such as ice , fog, gravel , heavy rain and hydro­
planing) -risk of accident.
• Turn off the cruise control temporarily when entering turn
lanes , highway exit lane s or in construction zone s.
• Please note that inadvertently " re sting" you r foot on the accel­
erator pedal causes the cruise control not to brake. This is because
the cruise control is overridden by the driver's acceleration .
• Never use the cruise control when driving off-road or on
unpaved roads . The Cruise control is intended for use only when
the vehicle is being operated on paved roads, and is not suitable
for use off-road or on unpaved roads.
[ i ] Tips
The cruise control cannot ma inta in a constant speed when d riving
dow nhill. The ve hicl e will accele rate unde r its own we igh t. D ownshift
to a Lower gear or use the brakes to slow down .•

& WARNING (continued)
the veh icle s afely when you follow another vehicle too closely.
Alway s rem ember that the Adaptive Cruise Control has a braking
powe r that is only about 30 % of the vehicle's maximum braking
ability. The automatic braking function cannot bring th e ve hicle to
a sudden or emergency stop . Always be prepared to brake and take
evasive action to avoid collisions and other accident situations .
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to
slow your vehicle safely. If closing speed is too h igh, you must
apply the brake s your self to reduce the ri sk of a rear-end cra sh .
• Never rest your foot on the accelerator pedal , especially when
the Adaptive Crui se Control is being used. Pressure on the acceler­
ator will overr ide the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brake s
must be applied .
• Never u se Adaptive Cruise Control when you cannot drive safely
at a steady speed, including on city streets , on winding roads or
when road conditions are poor (for example , on ice, gravel, in fog ,
heavy rain or on wet roads that increase the risk of hydroplaning ).
• The radar sensor's
vi sion can be redu ced by rain, snow and
heavy road spray. These and similar conditions can prevent vehi­
cle s up ahead from being accurately detected and in some cases
they may not be detected at all. Do not use ACC when the radar
sensors cannot accurately detect vehicles mo ving ahead of you in
traffic .
• Always turn off Adaptive Crui se Control when entering turn
lanes, exit lanes and con struction zones or in similar situat ions
because the vehicle will automatically accelerate to the stored
speed when the road ahead i s clear .
• To prevent unintended operation , always switch ACC off when
it is not being used .

How does Adaptive Cruise Control work?
Vehicles traveling ahead ore detected with the aid of a
radar sensor.
Fig. 132 Basic prin­
ciple diagram: Radar
sensor measurement
range
Adaptive Cruise Control uses a radar sensor in the front of the vehicle
=>
page 138, fig. 132 . The system has limitations=> page 149.
Things that are not moving in your lane and in your direction of travel
w ill not be detected. The sensor measures the distance to reflective
surfaces that must have a certain size. The system responds only
after the distance measurement has been made . If a measurement is
not possible, the system cannot respond and will not react to a
vehicle or someth ing else up ahead.
Open road
When the road is clear, the Adaptive Cru ise Control works like cruise
control. It maintains a constant target speed specified by the driver .
Driving in traffic
If a slower veh icle driv ing ahead is detected, the Adaptive Cruise
Control decelerates (within the limits of the system)=>
page 148,
"Driver intervention prompt" and => page 149, "System limitations"
to its speed and after adjusting, tries to ma inta in the set distance
from the vehicle ahead. The vehicle may temporarily drive slower
than the set speed whi le adjusting=>
& in "Descr iption" on
page 136.
If the vehicle in front accelerates, Adaptive Cruise Control also accel­
erates up to the speed that you have set.
If the vehicle ahead slows to a stop, ACC w ill slow your vehicle down
and to a complete stop if this is possible within the system's limits
and capabilities . ACC will not make an emergency stop. The text
message
ACC off: manual control! appears in the instrument cluster
display. Once the vehicle stops, you must depress the brake pedal to
prevent the veh icle from moving forward or "creeping". Depressing
the brake pedal turns off ACC. When the vehicle ahead accelerates
you can reactivate ACC =>
page 141, as soon as your vehicle has
reached a speed of 1 mph (2 km/h) .
Situations requiring driver intervention
In some situations you will have to use the footbrake to slow the
vehicle down in order to keep a safe distance from vehicle in front of
you or to avoid a rear-end collision. In this situation, a symbol
appears and a warning tone sounds=>
page 148.
Passing another vehicle
If you move into the passing lane and no vehicle is detected ahead,
the Adaptive Cruise Control accelerates to the speed you have set and
maintains it.
Overriding ACC
You can increase your speed at any time by stepping on the acceler ­
ator pedal. After you release the accelerator pedal, the system
adjusts back down to the speed you previously set.
Reduc ing stopping distance
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum distance, the brakes are automatically
prepared for emergency braking by the driver. The brake pads are
moved very close to the brake discs withou t actually bra king the
vehicle. This brake assistant feature reacts more quickly to the driver's braking, and also works when Adaptive Cruise Control is off.
The stopping d istance is reduced as a result of this advance brake .,_

man eu ver s by its elf; th e dr iver m ust alway s app ly the b ra kes .
& WARNING
If ACC initiates a braking maneuver, the brake pedal will be
retracted . Interference with the brake pedal can prevent ACC from
slowing the vehicle down and cause a crash and serious personal
injury .
• Never put anything in the driver's footwell or let anything fall
into it. An object in the driver 's footwell can interfere with the
pedals and prevent the accelerator from being used to override
ACC or prevent ACC from being switched off when the brake pedal
is depressed and also prevent the vehicle from being slowed down
or stopped.
• Only use floor mats that keep the area around the pedals free
and that can be securely fastened to the footwell.
• Never drive with your foot underneath the brake pedal.
• Always read and heed the information and WARNINGS~
& in
" Description " on
page 136.
& WARNING
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely. If closing speed is too high , you must
apply the brakes yourself to reduce the risk of a rear-end crash.
