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.

Potential Issues
OnStar cannot perform
Remote Door Unlock or Stolen
Vehicle Assistance after the
vehicle has been off
continuously for an extended
period of time without being
started. To find out the
duration of time that applies
for the vehicle, contact an

.Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;

area with very dense trees.
If GPS signals are not
available, the OnStar system
should still operate to callOnStar. However, OnStar
could have difficulty
identifying the exact
location.
.In emergency situations,
OnStar can use the last
stored GPS location to send
to emergency responders.
A temporary loss of GPS can
cause loss of the ability to
send a Turn-by-Turn
Navigation route. The Advisor
may give a verbal route or may
ask for a call back after the
vehicle is driven into an
open area.
Cellular and GPS

features to function properly.
These systems may not
operate if the battery is
discharged or disconnected.
