Recording Data - Volvo V70 Owner's Manual

When there is a series of illustrations for
step-by-step instructions each step is
numbered in the same way as the corres-
ponding illustration.
There are numbered lists with letters
adjacent to the series of illustrations
where the order of the instructions is not
significant.
Arrows appear numbered and unnum-
bered and are used to illustrate a move-
ment.
Arrows with letters are used to clarify a
movement when the reciprocal order is of
no relevance.
If there is no series of illustrations for step-by-
step instructions then the different steps are
numbered with normal numbers.
Position lists
Red circles containing a number are used
in overview images where different com-
ponents are pointed out. The number
recurs in the position list featured in con-
nection with the illustration that describes
the item.
Bulleted lists
A bulleted list is used when there is a list of
points in the owner's manual.
Example:
•
Coolant
•
Engine oil
Related information
Related information refers to other sections
containing related information.
Images
The manual's images are sometimes sche-
matic and may deviate from the car's appear-
ance depending on equipment level and mar-
ket.

01 Introduction

Recording data

Certain information about the vehicle's opera-
tion and functionality, and any incidents, are
recorded in the car.
Your vehicle contains a number of computers
whose function is to continuously check and
monitor the vehicle's operation and function-
ality. Some of the computers can record
information during normal driving if they
detect an error. In addition, information is
recorded in the event of a collision or inci-
dent. Parts of the recorded information are
required so that technicians can diagnose
and rectify faults in the vehicle during servic-
ing and maintenance and so that Volvo can
fulfil legal requirements and other regulations.
In addition to this, the information is used for
research purposes by Volvo in order to con-
tinually develop quality and safety, as the
information can contribute to a better under-
standing of the factors that cause accidents
and injuries. The information includes details
of the status and functionality of various sys-
tems and modules in the vehicle with regard
to engine, throttle, steering and brake sys-
tems, amongst other things. This information
may include details regarding the way the
driver drives the vehicle, such as vehicle
speed, brake and accelerator pedal use,
steering wheel movement and whether or not
the driver and passengers have used their
seatbelts. For the reasons given this informa-
tion may be stored in the vehicle's computers
