ab o ut data
re cord e d by
vehicle
control
modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event w ithout the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle
systems such as, for example, engine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehicle-related data
during norma l vehicle operation for diagnostic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit. Some
of the data then stored may relate to vehic le speed, direction,
braking as well as restraint system use and performance in the
event of a crash or other condition . Stored data can only be read and
downloaded with special equipment. •

The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDS)
and Anti-Slip Regulation System (ASR) are integrated in the Elec-
tronic Stabilization Program (ESP!. It increases contro l over the
vehic le in hand ling conditions close to the limit of "grip", such as
when accelerating and cornering. It reduces the risk of skidding
under all road condit ions and at all speeds and improves vehicle
stability. When road conditions are poor, ESP makes it easier to start
from a complete stop as well as accelerate and drive up hills . ESP
switches on automatically when you start the engine. It should
nor mally be activated at all times because this ensures optimum
vehic le stability.
Critic a l driving
sit u ation s
With an oversteering vehicle (the vehicle turns too sharply and the
rear wheels slide toward the outside of a curve), ESP pr i marily
brakes the outside front whee l, with an
understeering
vehicle (the
vehic le does not turn sharply enough and pushes out of a curve) it _,.
