facility could void
authorization to use this
equipment.
Vehicle Storage
The best way to store the
vehicle for any length of time
is to plug in the charge cord
and leave it plugged in. The
vehicle monitors and maintains
the 12-volt battery daily. It is
okay to leave the vehicle
plugged in for extended
periods of time. Once charged
to full, very little energy is
required to maintain the
12-volt battery and high
voltage battery.
If it is not possible to charge
the vehicle with the charge
cord left plugged in, be sure to
fully charge the high voltage
battery before storing. The
vehicle will stop maintenance
of the 12-volt battery if the
high voltage battery state of
charge gets too low.When storing the vehicle on a
long-term basis:
‐
Keep the high voltage
battery state of charge
at 30%.
‐ Attach an AGM/VRLA
compatible battery tender or
trickle charger to the 12-volt
battery.
‐ Keep the remote key more
than 3 m (10 ft) away from
the vehicle.
12–volt Battery
{Warning
Batteries have acid that can
burn you and gas that can
explode. You can be badly
hurt if you are not careful.
Always wear eye protection.
See Jump Starting - North
America 0356 for tips on
working around a battery
without getting hurt.
A trickle charger may be
attached to the 12-volt battery
terminals or trickle charge from the underhood remote
positive (+) and negative (–)
terminals. See Jump Starting -
North America
0356 for
location of these terminals.
Caution
The vehicle is equipped with
an AGM/VRLA 12-volt
battery, which can be
damaged by using the
incorrect type of trickle
charger. An AGM/
VRLA-compatible charger
must be used, with the
appropriate setting
selected. Follow the trickle
charger manufacturer
instructions.
With a trickle charger
connected to the 12-volt
battery, the vehicle will still
monitor the 12-volt battery
daily, but it will not use energy
from the high voltage battery
for maintenance.

{Warning
Driving on a flat tire will
cause permanent damage to
the tire. Re-inflating a tire
after it has been driven on
while severely underinflated
or flat may cause a blowout
and a serious crash. Never
attempt to re-inflate a tire
that has been driven on
while severely underinflated
or flat. Have your dealer or
an authorized tire service
center repair or replace the
flat tire as soon as possible.
If a tire goes flat, avoid further
tire and wheel damage by
driving slowly to a level place,
well off the road, if possible.
Turn on the hazard warning
flashers. See Hazard Warning
Flashers 0145.

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.
Use eye protection when
handling the battery. If you
do not follow these steps
exactly, some or all of these
things can hurt you.

6. Remove the covers of thepositive and negative
terminals.
7. Locate the battery positive (+) terminal and
negative (−) grounding point.
8. Check that the jumper cables do not have loose or
missing insulation. If they do,
you could get a shock. The
vehicles could be
damaged too.
9. Connect one end of the red positive (+) cable to the
discharged battery
positive (+) terminal. Do not
let the other end touch
metal.
10. Connect the other end of the red positive (+) cable to
the good battery positive (+)
terminal.
11. Connect one end of the black negative (−) cable to
the good battery negative
(−) terminal.
Do not let the other end
touch anything until the
next step. 12. Connect the other end of
the negative (−) cable to the
discharged battery negative
(−) grounding point.
13. Now start the vehicle with the good battery and keep
the vehicle running for a
while.
14. Try to start the vehicle that had the dead battery. If it
will not start after a few
tries, it probably needs
service.
Caution
If the jumper cables are
connected or removed in the
wrong order, electrical
shorting may occur and
damage the vehicle. The
repairs would not be
covered by the vehicle
warranty. Always connect
and remove the jumper
cables in the correct order,
making sure that the cables
do not touch each other or
other metal. Jumper Cable Removal
Reverse the sequence exactly
when removing the jumper
cables.
After starting the disabled
vehicle and removing the
jumper cables, allow it to idle
for several minutes.
