General

1 Two types of speedometer drive
mechanism have been fitted. Vehicles built

before 1987 have a conventional speedometer
cable, which drives the speedometer remotely,
by means of a cable with a rotating, flexible
inner shaft.
2 An erratic or inconsistent speedometer
display, such as needle flickering or jumping,
may be attributable to wear in the
speedometer drive cable.

3 Vehicles built after 1987 are fitted with an
electronic transducer in place of the drivegear.
This device measures the rotational speed of
the transmission final drive, and converts the
information into an electronic signal, which is
then sent to the speedometer module in the
instrument panel. The signal is also used as an
input by the engine management system ECU
(and where fitted, the cruise control ECU, the

trip computer, and the traction control system

ECU).

Removal

4 Refer to the relevant paragraphs of Chap-
ter 11, Section 27, and remove the panel from
the top of the facia.
5 With reference to Chapter 3, remove the air
ducting from above the instrument panel.
6 Disconnect the drive cable from the rear of
the speedometer module.
7 Release the cable from the clips securing it
to the inside of the facia, then pull the free end
of cable through the bulkhead into the engine
bay, noting the cable routing. Do not use
excessive force, as this may damage the
rubber grommet at the bulkhead.
8 At the gearbox, unscrew the knurled nut at
the point where the speedometer cable enters
the differential casing. Withdraw the cable
inner from the drivegear.
9 Remove the speedometer cable from the
vehicle.

Refitting

10 Refit the speedometer drive cable by
reversing the removal process. Follow the

same routing behind the facia as the original
drive cable, ensuring that all moving
components are avoided. Do not force the
cable to follow tight curves, as this may
adversely affect the rotation of the cable inner.

unit dismantling procedure.

General

1 The windscreen, tailgate and headlight
washer jets are all supplied by one electric
pump, which is mounted on the washer fluid
reservoir.
2 The mounting position of the fluid reservoir
depends on the age of the vehicle. On earlier
vehicles, the reservoir is screwed to the left-
hand inner wing, in front of the battery tray. On
later models, the fluid reservoir is mounted
inside the right-hand wing cavity, in front of

At the time of writing, very little detailed

information was available regarding the anti-
theft alarm. It is recommended that any
problems or queries with the system should be
referred to a Saab dealer.

All models are fitted with thermostatically-

regulated heated front seats. Individual control

switches are provided for each seat, which
allow the heating element temperature to be
set to one of three levels, or switched off
completely.

Two heating elements are fitted to each seat

- one in the backrest, and one in the seat
cushion. Access to the heating elements can
only be gained by removing the upholstery
from the seat - this is an operation which
should be entrusted to a Saab dealer.

All models have a wiring connector already

wired up for a tow bar located in the luggage
compartment. For further information
regarding this component contact your local
Saab dealer.
