Battery Level Protection
Caution: If the battery is not capable of starting the engine,
replace the battery as soon as possible.
Using vehicle electrical systems such as the infotainment system,
with the ignition ON, but the engine OFF, will drain the battery
charge.
To prevent battery voltage falling below the level required to start
the vehicle, the vehicle's battery monitoring system will shut
down non-essential electrical systems before this happens.
After approximately 2 to 10 minutes (dependent on the rate of
battery charge drain) a message is shown in the infotainment
display.
If a low battery warning message shows, start the engine and let
it idle so the battery can recharge
charger or conditioner.
If driving the vehicle to recharge the battery, a journey distance of
1.
approximately 30 miles or 48 km will be sufficient to recharge the
battery.

Vehicle Battery Disposal
The incorrect disposal of a vehicle battery can be extremely
hazardous to health and the environment. Most batteries contain
materials that, when disposed of incorrectly, may leak into the
environment. This can contribute to soil and water pollution and
endanger wildlife.
Do not dispose of a battery in fire or water.
Follow your local authorized standards for disposal. Call your
local authorized recycling centre to find out more about recycling
automotive batteries. Do not dispose of your vehicle battery in
the household waste.
