2014 AUDI TT ROADSTER differential

18 Instrum ent s and w arn ing /indic ato r light s
-The light illuminates when the convertib le
top is opened or closed incompletely.
nlfJ Electronic Stabilization Control
(ESC)
If the Ji) indicator lamp blinks while driving,
the ESC or ASR (Ant i-Slip Regulation) is active­
l y regulating .
If the
Ji) indicator lamp illuminates, the sys­
tem has switched the ESC off. In this case, you
can switch the ignition
off and then on to
switch the ESC on again . The system is func­
tioning comp letely whe n the indicator lamp
switches off.
If the
i indicator lamp illuminates, the ESC
was switched
off with the [ru button .
Stabiliz ation prog ram and ABS fault! See
own er's manu al
If the J;.J indicator lamp and the El ABS indi­
cator lamp illuminate and the dr iver message
appears, the ABS or e lec tronic differential lock
is ma lfunctioning . This also interrupts the
ESC. The brakes st ill function with the ir nor­
mal power, but ABS is not active .
Drive to your authorized Aud i dea ler immedi­
ately to have the malfunction corrected .

ABS/ (8 ) Anti-lock brake system
This warning/indicator light monitors the ABS
and the electronic differential lock (EDL).
The warning/indicator light
E (USA mod ­
e ls)
;riJ (Canada mode ls) will come on for a
few seconds when the ignition is sw itched on .
The light will go out after an automatic check
sequence is comple ted.
The re i s a malfuncti on in the ABS when :
-The warning/indicator light does not ill umi­
nate when you switch the ign ition on.
- The warning/indicator light does not go out
after a few seconds . - The warning/
indica tor light i lluminates
while driving .
T he ESC indi cator lig ht also illum inates if
there is a ma lf u nction in the ABS. The mes­

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru. Be sure to
switch ESC on again when you no longer need
less traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking . Apply steady pres ­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to
normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot overcome
th e laws of physics. This is especially im ­
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve­
hicle, you should immediately change
your speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligent technology 143
to take risks. Doing so will increase the
risk of a lo ss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot prevent colli­
sions.
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire si zes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working.
- If the ind icator lightD] orE (USA
models)/ [iJ (Canada models) appears,
there may be a malfunction¢
