Replacing the handset battery
The handset battery should last for
approximately one year depending on use.
When the battery needs replacing, you’ll
notice a deterioration in performance. For
example, you’ll gradually need to be closer
to the vehicle to operate the handset.
To replace the battery:
1. Insert a screwdriver into the top of the
handset and carefully separate the two
halves. Avoid damaging the seal
between the two halves.
2. Remove the battery, taking care to
avoid touching the circuit board or the
contact surfaces of the battery holder.
3. Fit the new battery (type CR2032)
with the ‘
+ ’ sides facing upwards.
If possible, avoid touching the flat
surfaces of the battery because finger
marks will reduce battery life. Wipe the
battery clean before fitting.
4. Re-assemble the two halves of the
handset by aligning them and pressing
them together until they snap into
place.
Vehicle immobiliser
Your vehicle is equipped with a vehicle
immobiliser that, when active, prevents
the vehicle from being started.
To switch off the immobiliser press the
Unlock button on the handset.
Note: Unless the starter switch is turned to
the ON position within 45 seconds of the
handset Unlock button being pressed, the
immobiliser will be reactivated. Press the
Unlock button on the handset again to
start the vehicle.
If the immobiliser is active when the
starter switch is turned to the ON position
a message will be displayed on the touch
screen advising you to switch off the
immobiliser. Press the unlock button on
the handset.
The immobiliser is automatically activated
when the vehicle is locked using the
handset or 45 seconds after the starter
switch is turned from the ON position to
the ACC or OFF position.
Note: If for any reason you cannot unlock
the vehicle using the handset, you will not
be able to switch off the immobiliser. Call
Roadside Assistance for help.
