Keep the vehicle plugged in, even
when fully charged, to keep the high
voltage battery temperature ready
for the next drive. This is important
when outside temperatures are
extremely hot or cold.
A vehicle cover, which can reduce
sun loading on the vehicle and
improve high voltage battery life, is
available from your dealer.
12-Volt Battery
The 12-volt battery is in the trunk,
under the center compartment
cover. Refer to the replacement
number shown on the original
battery label when a new 12-volt
battery is needed. The vehicle has
an Absorbed Glass Mat (AGM)
12-volt battery. Installation of a
standard 12-volt battery will result in
reduced 12-volt battery life.
When using a 12-volt battery
charger on the 12-volt AGM battery,
some chargers have an AGM
battery setting on the charger.
If available, use the AGM setting on
the charger, to limit charge voltage
to 14.8 volts. Follow the charger
manufacturer's instructions.{Warning
WARNING:Battery posts,
terminals, and related

{Warning
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. See Jump Starting -
North America 0299 for tips on
working around a battery without
getting hurt. Up to four weeks
.
Plug in the high voltage battery
charge cord if temperatures will
exceed 35 °C (95 °F) and keep
the 12-volt battery cables
connected.
Four weeks to 12 months
. Discharge the high voltage
battery until two or three bars
remain on the battery range
indicator (Battery symbol) on the
instrument cluster.
. Do not plug in the high voltage
battery charge cord.
. Remove the black negative (−)
cable from the 12-volt battery.
Attach a trickle charger to the
battery terminals or keep the
12-volt battery cables connected
and trickle charge from the

Jump Starting
Jump Starting - North
America
Jump starting is connecting jumper
cables between the two vehicles to
enable vehicle starting. If the ELR or
another vehicle has a run-down
12-volt battery, it can be jump
started using good condition jumper
cables.
{Warning
The high voltage battery cannot
be jump started either with
another vehicle or battery
charger. Personal injury, death,
or damage to the vehicle could
result.

Proposition 65 Warning 0236.
{Warning
Batteries can hurt you. They can
be dangerous because:
. They contain acid that can
burn you.
. They contain gas that can
explode or ignite.
. They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you.
{Warning
Electric fans can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fans.
Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
Jump Starting the ELR
If the ELR will not start, the 12-volt
battery may be run down. To jump
start the ELR, jumper cables are
connected directly to the positive (+)
and negative (−) terminals on the
12-volt battery in the rear
cargo area.

1. Positive (+) Terminal
2. Negative (−) Terminal
1. The other vehicle used to jumpstart the ELR must have a
12-volt battery with a negative
ground system.
Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting. 2. Park both vehicles close
enough so that the jumper
cables can reach both vehicles'
positive (+) and negative (−)
terminals. The vehicles must
not touch each other. It could
cause an unwanted ground
connection that could damage
both vehicles' electrical
systems.
Put both vehicles in P (Park)
for an automatic transmission
or electric drive unit. For a
manual transmission, place the
vehicle in Neutral and set the
parking brake.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting. 3. Turn off the ignition on the
other vehicle. Turn off the
radio, all lamps, and
accessories that are not
needed in both vehicles.
Unplug accessories from the
cigarette lighter or the
accessory power outlets. This
avoids sparks and helps save
both batteries and accessories.
4. Locate the positive (+) and negative (−) terminals on the
other vehicle.
5. Locate the positive (+) and negative (−) battery terminals
on the ELR. The access cover
is under the load floor access
cover in the rear cargo area.
Open the access covers for the
positive (+) terminal (1) and the
negative (−) terminal (2).
6. Check that the jumper cables do not have loose or missing
insulation or a shock could
result and the vehicles could
be damaged.
Before connecting the jumper
cables, here are some basic
things to know. Positive (+)
