Jacking And Vehicle Support; Disconnecting The Battery - Opel Zafira B MPV 2006 Owners Workshop Manual

The jack supplied with the vehicle tool kit
should only be used for changing roadwheels
- see Wheel changing at the front of this
manual. Ensure the jack head is correctly
engaged before attempting to raise the
vehicle. When carrying out any other kind of
work, raise the vehicle using a hydraulic jack,
and always supplement the jack with axle

axle stands
Numerous systems fitted to the vehicle
require battery power to be available at
all times, either to ensure their continued
operation (such as the clock) or to maintain
control unit memories which would be erased
if the battery were to be disconnected.
Whenever the battery is to be disconnected
therefore, first note the following, to ensure
that there are no unforeseen consequences of
this action:
a) First, on any vehicle with central locking,
it
is a
wise precaution to remove the key
from the ignition, and to keep it with you,
so that it does not get locked in, if the
central locking should engage accidentally
when the battery is reconnected.
b) Depending on model and specification,
the Vauxhall anti-theft alarm system may
be of the type which is automatically
activated when the vehicle battery is
disconnected and/or reconnected. To
prevent the alarm sounding on models so
equipped, switch the ignition on, then off,
and disconnect the battery within
15 seconds. If the alarm is activated
when the battery is reconnected, switch
the ignition on then off to deactivate the
alarm.
c) If
a
security-coded audio unit is fitted,
and the unit and/or the battery is
disconnected, the unit will not function
again on reconnection until the correct

stands positioned under the vehicle jacking
points.
When jacking up the vehicle with a trolley
jack, position the jack head under one of the
relevant jacking points. Use a block of wood
between the jack or axle stand and the sill -
the block of wood should have a groove cut
into it , in which the welded flange of the sill

will locate. Do not jack the vehicle under the
sump or any of the steering or suspension
components. Supplement the jack using axle
stands (see illustrations).
A
Warning: Never work under,
around, or near
a
raised vehicle,
unless it is adequately supported
in at least two places.
Axle stands should be placed under, or
adjacent to the jacking point (arrowed)

security code is entered. Details of this
procedure, which varies according to the
unit fitted, are given in the vehicle audio
system operating instructions. Ensure
you have the correct code before you
disconnect the battery. If you do not
have the code or details of the correct
procedure, but can supply proof of
ownership and
a
legitimate reason for
wanting this information,
a
Vauxhall dealer
may be able to help.
d) The engine management electronic
control unit is of the 'self-learning' type,
meaning that as it operates, it also
monitors and stores the settings which
give optimum engine performance
under all operating conditions. When the
battery
is
disconnected, these settings
are lost and the ECU reverts to the base
settings programmed into its memory at
the factory. On restarting, this may lead
to the engine running/idling roughly for
a
short while, until the ECU has relearned
the optimum settings. This process is
best accomplished by taking the vehicle
on
a
road test (for approximately 15 min-
utes), covering all engine speeds and
loads, concentrating mainly in the 2500
to 3500 rpm region.
e) On models equipped with automatic
transmission, the transmission selector
lever assembly incorporates an
electrically-operated selector lever lock
mechanism that prevents the lever being
moved out of the P position unless the
ignition is switched on and the brake
pedal is depressed. If the selector lever
is in the P position and the battery
is
disconnected, it will not be possible to
move the selector lever out of position
P by the normal means. Although it is
possible to manually override the system
(see Chapter 78), it is sensible to move
the selector lever to the N position before
disconnecting the battery.
f) On models with electric windows, it will
be necessary to reprogramme the motors
to restore the one-touch function of the
buttons, after reconnection of the battery.
To do this, fully close both front windows.
With the windows closed, depress the
up button of the driver's side window for
approximately 5 seconds, then release it
and depress the passenger side window
up button for approximately
5
seconds.
g) On models with an electric sliding
sunroof, it will be necessary to fully open
and fully close the sunroof after battery
reconnection, to recalibrate the sensors.
h) On all models, when reconnecting the
battery after disconnection, switch on the
ignition and wait 10 seconds to allow the
electronic vehicle systems to stabilise and
re-initialise.
