How to recover the vehicle with a
discharged 12V or HV battery
If the 12V battery has become discharged, the
parking brake must be released to enable the
vehicle to be towed away. This can be done once
the 12V battery is recovered. To recover the 12V
battery please contact your McLaren retailer.
WARNING: When the 12V battery is
discharged, only use a 12V slave
battery to energise the system to
release the parking brake. Any other
voltage source could cause serious
damage to your vehicle.
WARNING: Before use, check that all
the cables are in good condition; do
not use cables that are damaged.
Attempt to release the parking brake (see
Parking brake, page 2.07). If the brake does not
release, please contact your nearest McLaren
retailer.
Make this information available to any third
parties that may be assisting in the recovery of
your McLaren.

12V battery charging safety
Before using the 12V battery charger, familiarise
yourself with the following safety information.
WARNING: Your McLaren is fitted with
two lithium-ion batteries. A 12V
battery and a High Voltage (HV)
battery. The 12V battery is charged
by the HV battery. A 12V battery
charger should only be used to charge
the 12V battery when access to a HV
charging cable is not available.
Contact your McLaren retailer for
more information.
WARNING: The lithium-ion batteries
fitted to your McLaren are sealed for
life and no attempt should be made
to break the battery seal to inspect
the battery cells.
WARNING: Have the 12V battery
tested by your McLaren retailer, once
a year or after 6,000 miles (10,000
km) and replaced if necessary. Your
McLaren retailer will inform you if it
is necessary to replace the 12V
battery.
WARNING: Leave the HV charging
cable plugged in and connected to
your vehicle during periods when
your vehicle is not in regular use. This
will help maintain the life of both the
HV battery and the 12V battery.
WARNING: If access to a HV charging
cable is not available, leave a suitable
12V battery charger connected to the
12V battery and switched on during
periods when your vehicle is not in
regular use. This will help maintain
and prolong the life of the battery.
WARNING: Before use, check that all
cables are in good condition; do not
use cables that are damaged.
Ensure that all cables are kept away
from sharp edges, are not pinched or
trapped and are not close to hot
surfaces or water.
The battery must only be charged in
a well ventilated area; the charger
must never be covered or placed on
the battery.
Do not place any metal objects on a
battery. You could cause a short
circuit and the battery could ignite.
