7-16 Maintenance
Battery lead disconnection
Note:
• Upon battery lead reconnection the
radio security code will be required
and the clock will need to be reset.
• Electrically operated door windows
must be reset to learn the anti-trap
function.
• If the battery is disconnected for more
than 72 hours the radio preset
channels will need to be reset upon
battery reconnection.
• The trip computer will lose all
recorded trip data and all trip
functions will be reset to zero. The
vehicle total odometer reading is
retained.
Caution:
1. Under no circumstances should a
battery be disconnected whilst
the ignition circuit is live, as
permanent damage to the
instrument cluster may occur.
2. Disconnect the negative lead
(earth terminal) first.
Open the bonnet and unclip the battery
box cover.
Slacken the negative lead pinch bolt and
disconnect the negative (–) battery lead.
Slacken the positive lead pinch bolt and
disconnect the positive (+) battery lead.
Clean the battery posts and coat the post
bases with petroleum jelly.
Battery lead connection
Note: Upon battery reconnection the
security system will be armed. Opening
any protected entry will sound the alarm.
Make sure that a key or key transmitter is
available.
Caution: Do not overtighten the
pinch bolts.
Connect the positive (+) lead, tighten the
pinch bolt and clip the positive terminal
cover on the battery. Connect the
negative (–) lead and tighten the pinch
bolt.
After the battery has been reconnected
and the ignition switch is turned to
position ‘II’, the message centre display, if
fitted, will initially show an erroneous
reading i.e. – – – – – –. This will remain
until after the bulb check sequence, when
the correct recorded mileage will be
displayed. This is a normal function of the
instrument cluster.
Note: When the battery is disconnected
and reconnected, some abnormal drive
symptoms may occur while the vehicle
relearns it’s adaptive strategy. The vehicle
may need to be driven 16 kilometres
(10 miles) or more to relearn the strategy.
Reset the clock to the correct time.
The radio will not operate until the
correct security code has been
re-entered. Refer to the Audio Systems
Handbook.
Reset the window anti-trap feature.
