1 General information
1 The bodyshell and underframe is of all-steel
welded construction, and is of computer-
originated design. The assembly and welding
of the main body unit is completed entirely by
computer-controlled robots, and the finished
unit is checked for dimensional accuracy
using computer and laser technology. In
accordance with current practice, the
bodyshell incorporates computer-calculated
impact crumple zones at the front and rear,
with a centre safety cell passenger
compartment. During manufacture the body is
dip-primed, fully sealed and undercoated,
then painted with multi-layered base and top
coats.
Interior equipment electronic
control unit recalibration
2 Many of the vehicles covered by this
manual are equipped with sophisticated
interior electrical systems utilising electronic
control units (ECU’s) for their operation.
Whenever the battery is disconnected and
reconnected, some of these systems will not
work properly until a recalibration procedure
is carried out to restore the values lost from
the ECU memories. The systems affected and
the recalibration procedure is as follows.
Windows and sun roof
3 Operation of the windows and sun roof will
be accompanied by a repetitive warning
“bleep” and the “one-touch” function and
“back-off” function will not operate.
4 To restore correct operation, fully open the
driver’s door window, in one continuous
operation, using the controls on the driver’s
door. When the window is open fully, hold the
switch in the “on” position until the warning
bleep stops sounding.
5 Now shut the window, in one continuous
operation, and holding the switch in the “on”
position as before, until the warning bleep
stops.
6 Repeat the above operations on all the
other windows.
7 Fully open and then shut the sun roof,
holding the switch in the “on” position at the
end of each movement, until the warning
bleep stops.
8 Full operation of the electric windows and
sun roof should now be restored. If not, repeat
the recalibration sequence.
Lazy locking
9 The lazy locking function will not operate
and instead, a warning “bleep” will sound. Full
operation will be restored by carrying out the
procedures for the window and sun roof
memories, as described above.
Seat and mirror positions
10 All the preset positions contained in the
seat and mirror position memories will be lost.
Re-enter and save new positions using the
same procedure as for the original positions.
Radio cassette and CD player
11 The words “CODE” or “ROVER-C” will
appear on the digital display and the set will
not operate. Re-enter the security code as
described in the Rover in-car entertainment
booklet.
2 Maintenance -
bodywork and underframe
1
The general condition of a vehicle’s
bodywork is the one thing that significantly
affects its value. Maintenance is easy, but
needs to be regular. Neglect, particularly after
minor damage, can lead quickly to further
deterioration and costly repair bills. It is
important also to keep watch on those parts of
the vehicle not immediately visible, for instance
the underside, inside all the wheel arches, and
the lower part of the engine compartment.
The basic maintenance routine for the
bodywork is washing - preferably with a lot of
water, from a hose. This will remove all the
loose solids which may have stuck to the
vehicle. It is important to flush these off in
such a way as to prevent grit from scratching
the finish. The wheel arches and underframe
need washing in the same way, to remove any
accumulated mud, which will retain moisture
and tend to encourage rust. Paradoxically
enough, the best time to clean the underframe
and wheel arches is in wet weather, when the
mud is thoroughly wet and soft. In very wet
weather, the underframe is usually cleaned of
large accumulations automatically, and this is
a good time for inspection.
Periodically, except on vehicles with a wax-
based underbody protective coating, it is a
good idea to have the whole of the
underframe of the vehicle steam-cleaned,
engine compartment included, so that a
thorough inspection can be carried out to see
what minor repairs and renovations are
necessary. Steam-cleaning is available at
many garages, and is necessary for the
removal of the accumulation of oily grime,
which sometimes is allowed to become thick
in certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-
applied; the dirt can then be simply hosed off.
Note that these methods should not be used
on vehicles with wax-based underbody
protective coating, or the coating will be
removed. Such vehicles should be inspected
annually, preferably just prior to Winter, when
the underbody should be washed down, and
any damage to the wax coating repaired.
Ideally, a completely fresh coat should be
applied. It would also be worth considering
the use of such wax-based protection for
injection into door panels, sills, box sections,
etc, as an additional safeguard against rust
damage, where such protection is not
provided by the vehicle manufacturer.
After washing paintwork, wipe off with a
chamois leather to give an unspotted clear
finish. A coat of clear protective wax polish will
give added protection against chemical
pollutants in the air. If the paintwork sheen has
dulled or oxidised, use a cleaner/polisher
combination to restore the brilliance of the
shine. This requires a little effort, but such
dulling is usually caused because regular
washing has been neglected. Care needs to be
taken with metallic paintwork, as special non-
abrasive cleaner/polisher is required to avoid
damage to the finish. Always check that the
door and ventilator opening drain holes and
pipes are completely clear, so that water can
be drained out. Brightwork should be treated in
the same way as paintwork. Windscreens and
windows can be kept clear of the smeary film
which often appears, by the use of proprietary
glass cleaner. Never use any form of wax or
other body or chromium polish on glass.
3 Maintenance -
upholstery and carpets
1
Mats and carpets should be brushed or
vacuum-cleaned regularly, to keep them free of
grit. If they are badly stained, remove them
from the vehicle for scrubbing or sponging, and
make quite sure they are dry before refitting.
Seats and interior trim panels can be kept
clean by wiping with a damp cloth. If they do
become stained (which can be more apparent
on light-coloured upholstery), use a little liquid
detergent and a soft nail brush to scour the
grime out of the grain of the material. Do not
forget to keep the headlining clean in the same
way as the upholstery. When using liquid
cleaners inside the vehicle, do not over-wet the
surfaces being cleaned. Excessive damp could
get into the seams and padded interior,
causing stains, offensive odours or even rot.
4 Minor body damage -
repair

Note: For more detailed information about
bodywork repair, Haynes Publishing produce
a book by Lindsay Porter called “The Car
Bodywork Repair Manual”. This incorporates
information on such aspects as rust treatment,
painting and glass-fibre repairs, as well as
details on more ambitious repairs involving
welding and panel beating.

If the inside of the vehicle
gets wet accidentally, it is
worthwhile taking some
trouble to dry it out properly,
particularly where carpets are involved.
Do not leave oil or electric heaters
inside the vehicle for this purpose.
