The instrument illumination (for dials and
needles) turns on when the ignition is on
and the vehicle lights are turned off. As
the daylight fades, the illumination of the
dials likewise dims automatically and wil l
go out completely when the outside light
is very low. This feature is meant to rem ind
you to switch on the headlights when out­
side light conditions become poor.
Engine coolant temperature gauge
The engine coolant gauge CD¢ fig. 3 only
works when the ignition is on . To prevent
damage to your eng ine, please note the fol­
l owing important points:
Engine cold
If only the LEDs at the bottom of the gauge
turn on, the eng ine has not reached operating
temperature yet . Avoid high engine speeds,
heavy engine loads and heavy throttle applica­
tions.
Normal temperatu re
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving cond i­
t ions. The LEDs higher up may turn on when
the engine is under heavy load or the exterior
temperature is high. This is no need to worry
as long as the. warning light in the instru­
ment cluster does not illuminate. If the LEDs
in the upper area of the disp lay and the indica­
tor light . in the instrument cluster display
turn on, the coolant temperature is too high

A WARNING
-Always observe the warn ing in

fore opening the hood and checking the

wheels co uld 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 Aud i dealer or a qua li­
fied workshop. Drive slowly and avoid sudden, hard brake applications.
- Canada models: If the brake warn ing

dent. Have your vehicle repaired immedi­
ately by your authorized Audi dealer or a
qualified workshop. Dr ive slowly and
avo id sudden, hard brake applicat ions.
- If the brake warning/indicator light does not go out after a few seconds and the
park ing brake is released, or lights up
wh ile you are driving, the fluid level in
the brake f luid 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 in ­
spected.
- Always keep in mind that after several
brake applications, yo u will need greater
pressure on the brake peda l to stop your
vehicle. Do not re ly on stra ined brakes to
respond w ith maximum stopp ing power
in critical situations. You must allow for
increased brak ing distances . The extra
distance used up by fad ing brakes could
lead to an acc ident.

(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev ­
el. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel,
and always before going on a long trip.
- The yellow oil level warning indication
l!I requires oil refill or workshop serv­
ice without delay. Do not wait until the
red oil pressure warning. starts to
flash before you respond to the low oil level warning
1!11. By then, your engine
may already have suffered serious dam­
age.
