In extreme cases, EDL a utomatica lly switches off
to help keep the brake on the braked whee l from
overheating. EDL w ill switch on again automati ­
cally when conditions have returned to normal.
Steering re commendat ion
The ESC helps to stabilize the ve hicle by chang ing
the steering torque.
I n vehicles with dynamic steeri ng*, ESC also
h e lps to stabilize the steering in critical s itua­
tions .
Electronic interaxle differential lock* /
sel ectiv e wheel torque control*
The electron ic in teraxle d iffe ren tial lock (front
wheel drive) or the selective wheel torq ue contro l
(all wheel drive) operates when driving through
curves. The front whee l on the ins ide of the cu rve
or both whee ls on the inside of the curve are
braked selectively as needed. Thi s allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions .
_&, WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
ci al ly impo rtant on slippe ry or wet roads. If
the sys tems begin acting to stabilize your
Switching on/off
Smart Technology
veh icle, you shou ld immediately change
your speed to matc h the road and traffic
conditions. Do not let the increased safety
provided by these systems tempt you to
take risks . Do ing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle inc reases when dr iving
too fast, espec ially through curves and on
slippery or wet roads, and when dr iving too
close to vehicles up ahead . The ESC and its
integrated systems cannot a lways prevent
coll isions -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth su rfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that can not always help to reduce
the risk of loss of vehicle cont rol.
{!) Tips
-ABS and ASR only work correct ly when a ll
four wheels are equipped w ith ident ica l
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine.

The ESC is designed to function in levels. Depend­
i ng on the level that is selected, the stabilization
function o f the ESC is limited or switched off . The

amount of s tabilization control will differ de­

Smart Technolog y
Clean off accumulated salt coating from
brake discs and pads w ith a few carefu l
brake applications .
- If you damage the front spoiler, or if you in­
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc ­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake c ircuit will impair the
braking capab ility result ing in an increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest autho rized
Audi dealer or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
- If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .
Electro-mechanical

The electro-mechanical power assist helps the
driver when steering.
Power steering adapts electronically based on
the vehicle speed .
Indicator lights and me ssages
• Stee ring defe cti ve! D o not dr ive vehicle!
If this indicator light tu rns on and stays on and
this message appears, the power steering may
have fai led .
Do

c on tinu e dr iving
If the indicator light turns on and the message
appears, the steer ing may be more difficult to
move or mo re sensitive than us ual. The steer ing
wheel may also be at an ang le when dr iv ing
straight.

Drive slowly to your authorized Audi dea ler or
qualified workshop to have the ma lf u nction cor­
rected.
' -r, ij Dynamic ste ering: i nitializing
If this driver message appears and the indicator
li ght is flashing on the i nstrume nt pane l, dynam­
i c steer ing* is being rein it ia lized . After sta rting
the engine, the steer ing whee l w ill move sligh tly.
Re-initialization might be necessary if the steer ­
ing whee l was moved hard to th e left and right
whi le the vehicle was not moving . The display
goe s out as soon as initiali zation is comp lete.

@ Tips
- If the . or 'T fl indicator light only stays on
for a short time, you may cont inue driving.

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right dir ection .
Using a spare tire with a tread pattern
intended for use in a specific direction
When us ing a spa re tire w ith a t read pa tte rn in­
t e nded fo r use in a specific d ir e ct ion, p lease no te
the following:
- The direction of rotation is marked by an
arrow
on the side of the tire .
-If the spare t ire has to be installed in the incor­
rect direction, use the spare tire only tempora­
rily since the tire will not be able to achieve i ts
o ptimum performanc e character istics wit h re­
gard to aquaplaning, noise and wea r.
- We recommend that you pay pa rticular atten­
t io n t o this fact du ring wet weat he r and t hat

Notes on wheel changing
P lease read the information ¢ page 212, New
tires or wheels
i f you are going to use a spare tire
which is different from the tires on your ve hicle.
Afte r you change a tire:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as po s­
sible by your authorized Audi dealer or quali­
fied workshop .
- With steel and alloy wheel rims , the wheel
bolts are correctly tightened at a torque of 90
ft lbs. (120 Nm ).
- If you notice th at the wheel bolt s are corroded
and difficult to turn while changing a tire ,
they should be replaced before you check the
tightening torque .
Emergency assistance
-Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover .
Until then , drive with extra care and at reduced
speed s.
_& WARNING
