MAINTENANCE BATTERY CONDITION - Td5
Remove
1.Remove drivers seat base.
2.Release clip securing battery cover.
3.Remove battery cover.
NOTE: The vehicle may be fitted with an
alarm and immobilisation system. To
prevent the alarm from sounding, it is
important that the following procedure is used
when disconnecting the battery.
4.Turn the ignition switch to position’II’, and then
to position’0’.
5.Remove the ignition key.
6.Disconnect the vehicle -ve terminal within 15
seconds.
NOTE: Always disconnect the -ve terminal
first. When replacing, connect the +ve
terminal first.
Check
The battery fitted to Td5 models is designed to be
maintenance free, so topping-up is not possible. On
the top of the battery is a battery indicator. When the
indicator shows:
GREEN - The battery is in a good state of charge.
DARK (turning to black) - The battery needs
charging.
CLEAR (or light yellow) - The battery needs
replacing. Do not charge the battery or jump start
the vehicle in this condition.
If the green dot is missing, the battery needs
charging.
NOTE: If the indicator shows clear or
yellow, tap the indicator with the handle of
a screwdriver to disperse any air bubbles.
If the indicator colour remains unchanged, the
battery will need replacing.
Refit
7.Clean and grease battery terminals and leads
with petroleum jelly.
8.Connect leads to battery (+ve first) and tighten
clamp bolts.
9.Fit battery cover and secure with clip.
10.Fit drivers seat base.

DESCRIPTION AND OPERATION Remote Handset
The remote handset is a separate unit from the vehicle key and is used to arm and disarm the alarm system. The
handset comprises two buttons; lock and unlock. The handset contains a battery (CR3032) and a printed circuit
board containing the circuitry to generate the RF signals.
NOTE: In selected markets, the vehicle key, when used in the drivers door key barrel switch, will
not disarm the alarm system.
The remote handset RF code consists of two parts. One part is a fixed code that is unique to the handset and the
second part is a rolling code which changes in accordance with a predetermined pattern. The anti-theft alarm ECU
can store the codes of up to four different remote handsets at any one time.
If the remote handset battery falls below a predetermined level, the handset will transmit an additional RF signal
code to the anti-theft alarm ECU when either button is depressed. The security LED will display this as two rapid
flashes every 0.5 seconds to visually display the low handset battery condition. This will continue for the 10
second confirmation period or until the ignition is switched on.
Resynchronisation of Remote Handset
If either the remote handset battery or the vehicle battery is removed or disconnected, the rolling part the handset
code is lost and the handset(s) need to be resynchronised to the anti-theft alarm ECU. The resynchronisation
procedure is as follows:
Disconnect the vehicle battery.
Wait for 30 seconds for residual current to dissipate.
Reconnect the vehicle battery.
Carefully prise the remote handset apart and remove the battery. Avoid unnecessary handling of the battery.
With the battery removed, press either the lock or unlock button several times to remove residual current from
the circuitry.
Check the handset battery with a voltmeter. If the battery voltage is less than 2.7 volts, replace the battery.
Ensure that the battery contact surfaces are clean and replace the battery in the handset clip with the + symbol
uppermost. Put the two halves of the handset case back together.
DO NOT press any buttons.
With the handset within range of the vehicle, press the lock button four times in quick succession. The
anti-theft alarm ECU will respond by locking the vehicle.
Press the unlock button once to complete the resynchronisation procedure.
