Vehicle Care 10-15
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans
should be running. If it is not, the
vehicle needs service. Turn off the
vehicle.
Cooling System (High
Voltage Battery)
During vehicle operation and also
during charging, the high voltage
battery cells in the vehicle are kept
within a normal operating
temperature range. If the
temperature rises above this
temperature, the battery cooling
system turns on the air conditioning
compressor and cools the coolant
until the correct temperature is
reached. If the temperature falls
below this temperature, a high
voltage heater, located in the
battery, heats the coolant until the
correct temperature is reached.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled with
a 50/50 mixture of DEX-COOL
®
engine coolant and deionized water.
If using this mixture, nothing else
needs to be added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule on
page 11-2.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery coolant
reservoir is in the engine
compartment. SeeEngine
Compartment Overview on
page 10-8.
Check to see if coolant is visible in
the high voltage battery coolant
reservoir. If coolant is visible but the
coolant level is below the cold fill
line, there could be a leak in the
cooling system.
The high voltage battery coolant
should only be serviced by a
qualified technician.

{Caution
.Using the wrong fluid can
badly damage brake
hydraulic system parts. For
example, just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can damage
brake hydraulic system parts
so badly that they will have to
be replaced. Do not let
someone put in the wrong
kind of fluid.
.If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Be careful not to
spill brake fluid on the
vehicle. If you do, wash it off
immediately.
Battery
This vehicle has a high voltage
battery and a standard 12-volt
battery.High Voltage Battery
If the vehicle is in a crash, the
sensing system may shut down the
high voltage system. When this
occurs, the high voltage battery is
disconnected and the vehicle will
not start. The SERVICE VEHICLE
SOON message in the Driver
Information Center (DIC) will be
displayed. Before the vehicle can be
operated again, it must be serviced
at your dealer.
See
“If a Crash Occurs” under
Collision Damage Repair on
page 13-8 andHigh Voltage Safety
Information on page 1-19. If an
airbag has inflated, see What Will
You See after an Airbag Inflates? on
page 3-24.
Only a trained service technician
with the proper knowledge and tools
should inspect, test, or replace the
high voltage battery. See your
dealer if the high voltage battery
needs service. The dealer has
information on how to recycle the high voltage battery. There is
also information available at
http://www.recyclemybattery.com.
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.

{Warning
Batteries are dangerous and can
cause injury. Batteries contain
acid and can explode or ignite.
They contain electricity that can
burn. Follow the exact steps
provided or injuries could occur.
Using an open flame near a
battery can cause battery gas to
explode; you or others could be
hurt. Battery acid can cause
blindness.
Be sure the battery in the other
vehicle has enough water. Add
water if the level is low. A low
water level could cause explosive
gas to be present.
Battery fluid contains acid that
can burn. If battery fluid gets in
eyes or on skin; flush with water
and get medical help immediately.
{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 jump
start the ELR must have a

10-72 Vehicle Care
{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 (+)
jumper cable goes to positive (+)
battery terminal or a remote
positive (+) terminal if available.
Negative (−) jumper cable goes
to negative (−) battery terminal
or a remote negative (−) terminal
if available. Do not connect
positive (+) to negative (−) or
there will be a short that may
damage the battery and other
parts of the vehicle.

high voltage battery to charge
the 12-volt battery. The jumper
cables can then be
disconnected. If the ELR does
not start, call your dealer or
Roadside Service. See
Roadside Service on page 13-5. Disconnecting the Jumper Cables
1. Disconnect the black negative
(−) jumper cable from the ELR.
Do not let the other end of the
cable touch anything until after
the next step.
2. Disconnect the black negative (−) jumper cable from the other
vehicle with the good battery.
3. Disconnect the red positive (+) jumper cable from the other
vehicle. Do not let the other end
of the cable touch anything until
after the next step.
4. Disconnect the red positive (+) jumper cable from the ELR.
Jump Starting Another Vehicle
When using the ELR to jump start
another vehicle with a run-down
battery, jumper cables are
connected directly to the positive (+)
and negative (−) terminals on the
12-volt battery in the rear
cargo area.
