Engine coolant temperature gauge
The engine coo lant gauge CD i=;, page 10, fig. 3
only works when the ign ition is on. To prevent
10
damage to your engine, please note the follow­
i ng important poi nts :
Engin e cold
If only the LEDs at the bottom of the gauge t urn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, heavy en­
gine loads and heavy thrott le app lications.
No rmal temperatu re
The eng ine has reac hed its operating tempera­
ture once the LEDs up to the center of the ga uge
turn on under normal driving conditions. The
LEDs higher up may turn on when the eng ine is
under heavy load or the exterior temperature is
high . This is no need to worry as long as the.
warning light in the instrument clus ter does not
ill uminat e. If the L EDs in the uppe r area of the
display and the in dicator light . in the inst ru ­
men t cluster d isp lay tur n on, the coo lant tempe r­

nal is also given.
A WARNING
- Always observe the warn ings in
c::> page 218, before opening the hood and
checking the brake flu id.
- Dr iving with low brake f luid is a safety haz­
ard. Stop the car and get professional assis­
tance .

author ized Audi dealer or other qualified ..,.

workshop and have the malfunction correct­ed.
- If the brake warning/indicator light does
not go out after a few seconds and the park­
ing brake is 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 situa­
tions. You must allow for increased braking
distances. The extra distance used up by
fading brakes could lead to an accident.
PARK/( ®) Electromechanical parking brake
The warning/indicator light monitors the elec­
tromechanical parking broke.
If the indicator light- (USA models)/ .
(Canada models) turns on, the parking brake was
set .
- (USA models) • (Canada models) Cau­
tion: Vehicle parked too steep
If the indicator light blinks and the message ap­
pears, there is not enough braking power to keep
the vehicle from rolling. The brakes have over­
heated. The vehicle could roll away even on a
small incline.

- L Engine cooling system malfunction
A malfunction in the engine cooling system must
be repaired as soon as possible.
• Switch off engine and check coolant level
