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.

2. Get the vehicles closeenough so the jumper
cables can reach, but make
sure the vehicles are not
touching each other.
Caution
If the vehicles touch each
other while jump starting, a
ground connection may
occur that disables your
vehicle and/or damages the
electrical systems of one or
both vehicles.
To avoid the possibility of
the vehicles rolling, set the
parking brake firmly on both
vehicles involved in the jump
start procedure. Put the
vehicles into P (Park). If the
other vehicle has a manual
transmission, put the vehicle
in N (Neutral) before setting
the parking brakes.
3. Turn off both vehicles. Unplug unnecessary
accessories plugged into
the cigarette lighter or the accessory power outlet.
Turn off the radio and all
lamps that are not needed.
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.

with drive axle tires on the
ground. Damage is not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with an electric parking
brake and/or an electronic
shifter. In the event of a loss
of 12-volt battery power, the
electric parking brake
cannot be released, and the
vehicle cannot be shifted to
N (Neutral). Tire skates or
dollies must be used under
the non-rolling tires to
prevent damage while
loading/unloading the
vehicle. Dragging the vehicle
will cause damage not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with a tow eye. Improper use
of the tow eye may cause
damage to the vehicle and is
not covered by the vehicle
warranty. If equipped, use
the tow eye to load the
vehicle onto a flatbed tow
truck from a flat road
surface, or to move the
vehicle a very short distance
at a walking pace. The tow
eye is not designed for
off-road recovery. The
vehicle must be in
N (Neutral) with the electric
parking brake released when
using the tow eye.
Contact a professional towing
service if the disabled vehicle
must be transported. GM
recommends a flatbed tow
truck to transport a disabled
vehicle. Use ramps to help
reduce approach angles,
if necessary. If equipped, a tow eye may be
located near the spare tire or
emergency jack. Do not use
the tow eye to pull the vehicle
from the snow, mud, sand,
or ditch. Tow eye threads may
have right or left-hand
threads. Use caution when
installing or removing the
tow eye.
The vehicle must be in
N (Neutral) and the electric
parking brake must be
released when loading the
vehicle onto a flatbed tow
truck.
