Maintenance
To Connect a Battery Conditioner
1. Insert the accessory socket
plug (B) into the accessory
socket (A) located in the
trunk, rear wall, right side.
2. Insert the mains plug (C)
into the mains supply.
3. Gently close, but do not
latch, the trunk lid. This
avoids possible damage to
the trunk lid water seal from
the battery conditioner
power cable.
With the trunk lid left open the vehicle doors can be locked and
armed.
To remove the battery conditioner first disconnect from the mains
supply, then from the vehicle socket.
Battery Protection Mode
Replace the battery as soon as possible, if the battery is not
capable of starting the engine.
Using the vehicle electrical systems, i.e. the infotainment system, with
the vehicle key at position ‘I’ (ignition OFF) will drain the battery
charge. Eventually the battery will drain to such a low level that it will
not start the engine.
To avoid this happening, a series of safety mechanisms shut down
nonessential electrical systems before excessive battery drain takes
place.
Frequently Asked Questions

[B] : LOW BATTERY
11.27
Maintenance
What should I do next?
Set all unnecessary electrical systems to OFF to reduce battery drain.
Start the engine to recharge the battery. Run the engine for a
reasonable length of time.
What happens if I ignore the warning messages?
After approximately two to ten minutes (dependent on the rate of
battery charge drain) the following messages will show:
[A] : INFOTAINMENT WILL BE SHUT DOWN 2 MINUTES (For 10
seconds).
[B] : LOW BATTERY POWER SAVE.
If the audio system is ON the sound will mute for 10 seconds and a
short ‘Beep’ will be heard when the message is first shown.
What should I do if these messages are shown?
Set all unnecessary electrical systems to OFF. Start the engine to
recharge the battery. Run the engine for a reasonable length of time.
What happens if I ignore second warning messages?
The infotainment system will shut down in two minutes. No other
electrical system will be shut down. This significantly reduces the rate
of battery drain. The following functionality will be lost:
• CD Player
• Navigation System
• Radio Tuner
What should I do if the infotainment system shuts down?
Start the engine to recharge the battery. Run the engine for a
reasonable length of time.
The infotainment system will not operate without the engine running
until the battery has regained its charge. With the engine running the
infotainment system will start up.
What is a reasonable length of time to run the engine?
The vehicle battery normally requires a journey of approximately 30
miles to recharge. Additionally, use the battery conditioner to restore
the vehicle battery charge.
What if I cannot restart the engine?
If the battery has been run down to a point where it will not start the
engine then an external battery charger
1
will be required or your
vehicle will require a ‘jump start’ (Refer to ’Jump Start From Another
Vehicle’, page 11.22).
1.
A battery conditioner is designed for conditioning of partially or fully
charged batteries. It will not effectively charge a discharged battery.
