210 Driving and Operating
After pressing the P (Park)
button, hold down the regular
brake pedal. If you cannot see
the P (Park) indicator in the
instrument cluster, it means
that the vehicle has not
shifted to P (Park).
Shifting out of Park
This vehicle is equipped with
an electric drive unit. To shift
out of P (Park) the vehicle
must be on, the brake pedal
applied, and the charge cord
unplugged.
Parking the vehicle in extreme
cold for several days without
the charge cord connected
may cause the vehicle not to
start. Plug the vehicle in to
allow the high voltage battery
to be warmed sufficiently.
To shift out of P (Park):1. Apply the brake pedal.
2. Press POWER
Oto turn the
vehicle on. 3. Verify that the vehicle is

vehicle is on, the vehicle ready
light is on, and the brake pedal
is applied when you are
attempting to shift out of
P (Park). If all of these are met
but the vehicle will not shift
out of P (Park), see your dealer
for service. If equipped, the Buckle to
Drive feature may prevent
shifting from P (Park). See

Information
For service and parts needs,
visit your dealer. You will
receive genuine GM parts and
GM-trained and supported
service people.
Genuine GM parts have one of
these marks:
California Perchlorate
Materials
Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt
pretensioners, and lithium
batteries contained in
electronic keys, may contain
perchlorate materials.
Perchlorate Material–special
handling may apply. See
www.dtsc.ca.gov/

Accessories and
Modifications
Adding non-dealer accessories
or making modifications to the
vehicle can affect vehicle
performance and safety,
including such things as
airbags, braking, stability, ride
and handling, emissions
systems, aerodynamics,
durability, Driver Assistance
Systems, and electronic
systems like antilock brakes,

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.

368 Vehicle Care
Caution (Continued)
used on roads for conditions
such as dust and ice. Always
wash the chrome with soap
and water after exposure.
Caution
To avoid surface damage on
wheels and wheel trim, do
not use strong soaps,
chemicals, abrasive polishes,
cleaners, or brushes. Use
only GM approved cleaners.
Do not drive the vehicle
through an automatic car
wash that uses silicon
carbide tire/wheel cleaning
brushes. Damage could
occur and the repairs would
not be covered by the
vehicle warranty.
Brake System
Visually inspect brake lines
and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Inspect disc brake padsfor wear and rotors for
surface condition. Inspect all
other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,
suspension, and chassis
components for damaged,
loose, or missing parts or signs
of wear at least once a year.
Inspect power steering for
proper electrical connections,
binding, cracks, chafing, etc.
Visually check constant
velocity joint boots and axle
seals for leaks.
Body Component
Lubrication
Lubricate all key lock cylinders,
hood hinges, and liftgate
hinges unless the components
are plastic. Applying silicone
grease on weatherstrips with
a clean cloth will make them
last longer, seal better, and
not stick or squeak.
Underbody Maintenance
At least twice a year, spring
and fall, use plain water to
flush any corrosive materials
from the underbody. Take care
to thoroughly clean any areas
where mud and other debris
can collect.
Do not directly power wash
the transfer case and/or
front/rear axle output seals.
High pressure water can
overcome the seals and
contaminate the fluid.
Contaminated fluid will
decrease the life of the
transfer case and/or axles and
should be replaced.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the
body repair shop applies
anti-corrosion material to
parts repaired or replaced to
restore corrosion protection.
