Electronic Differential Lock (Edl) - Audi allroad 2001 Owner's Manual

VEHICLE OPERATION
'4 WARNING continued
Before descending a steep
•
grade, reduce speed and shift
transmission into a lower gear or
lower driving position. Do not ride
the brakes or hold the pedal down
too long or too often. This could
cause the brakes to get hot and di­
minish braking efficiency.
If you damage the front spoiler,
•
or if you install a different spoiler,
be sure the air flow to the front
brakes is not obstructed. Other­
wise the brake system could over­
heat reducing the effectiveness of
the entire brake system.
Failure of one brake circuit will
•
impair the braking capability re­
sulting in an increased stopping
distance.
Avoid driving the vehicle and have
it towed to the nearest Audi Dealer
or qualified workshop.

Electronic differential lock (EDL)

The EDL operates in conjunction with the
ABS. The EDL acts automatically, i.e. with­
out the driver's intervention.
With the aid of the ABS sensors, this sy­
stem monitors the speed of the driven
wheels up to about 50 mph, 80 km/h.
Within the speed range at which this sy­
stem operates, i f the wheels spin (e.g. on
slippery surfaces) they are braked in a con­
trolled manner, and more of the engine's
power is directed to whichever wheels
achieve greater traction.
Please note:
When driving off, always be sure to keep
•
road conditions in mind as you accelerate.
If a drive wheel spins because it's on a slip­
perier surface, gradually increase the pres­
sure on the accelerator pedal until the car
starts to move.
When accelerating on slippery surfaces,
•
such as on ice or snow, always be careful
when depressing the accelerator pedal.
Even with the EDL working, the drive
wheels can spin and reduce your ability to
control your car.
To prevent the disc brake of the braked
•
wheel from overheating, if subjected to ex­
cessive loads the EDL cuts out temporarily.
The vehicle remains operational and be­
haves in the same way as a vehicle without
EDL
If a fault occurs in the ABS the EDL is also
not functioning. This is indicated by the ABS
warning light - see page
125.
ftl WARNING
The increased safety afforded by
EDL does not mean that you can
take safety risks. Always adapt
your driving style to the road con­
ditions and traffic situation.
