Seats and Restraints 69
1. Turn the vehicle off.
2. Remove the child restraintfrom the vehicle.
3. Remove any additional items from the seat such as
blankets, cushions, seat
covers, seat heaters,
or seat massagers.
4. Reinstall the child restraint following the directions
provided by the child
restraint manufacturer and
refer to Securing Child
Restraints (With the Seat
Belt in the Front Seat) 090
or Securing Child Restraints
(With the Seat Belt in the
Rear Seat) 088.
Make sure the seat belt
retractor is locked by pulling
the shoulder belt all the way
out of the retractor when
installing the child restraint,
even if the child restraint is
equipped with a seat belt
lock off. When the retractor
lock is set, the belt can be
tightened but not pulled out
of the retractor. 5. If, after reinstalling the child
restraint and restarting the
vehicle, the ON indicator is
still lit, turn the vehicle off.
Then slightly recline the
vehicle seatback and adjust
the seat cushion,
if adjustable, to make sure
that the vehicle seatback is
not pushing the child
restraint into the seat
cushion.
Also make sure the child
restraint is not trapped
under the vehicle head
restraint. If this happens,
adjust the head restraint.
See Head Restraints 038.
6. Restart the vehicle.
The passenger sensing
system may or may not turn
off the airbags for a child in a
child restraint depending upon
the child’s size. It is better to
secure the child restraint in a
rear seat. Never put a
rear-facing child restraint in
the front seat, even if the ON
indicator is not lit.If the Off Indicator Is Lit
for an Adult-Sized
Occupant
If a person of adult size is
sitting in the front outboard
passenger seat, but the OFF
indicator is lit, it could be
because that person is not
sitting properly in the seat or
that the child restraint locking
feature is engaged. Use the
following steps to allow the
system to detect that person
and enable the front outboard
passenger frontal airbag and
knee airbag:

1. Turn the vehicle off.
2. Remove any additionalmaterial from the seat, such
as blankets, cushions, seat
covers, seat heaters,
or seat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the
seat cushion, with legs
comfortably extended.
5. If the shoulder portion of the belt is pulled out all the
way, the child restraint
locking feature will be
engaged. This may
unintentionally cause the
passenger sensing system
to turn the airbag off for
some adult-sized occupants.
If this happens, unbuckle the
belt, let the belt go back all
the way, and then buckle
the belt again without
pulling the belt out all
the way. 6. Restart the vehicle and
have the person remain in
this position for two to
three minutes after the ON
indicator is lit.
{Warning
If the front outboard
passenger airbag is turned
off for an adult-sized
occupant, the airbag will not
be able to inflate and help
protect that person in a
crash, resulting in an
increased risk of serious
injury or even death. An
adult-sized occupant should
not ride in the front
outboard passenger seat,
if the passenger airbag OFF
indicator is lit.
Additional Factors
Affecting System
Operation
Seat belts help keep the
passenger in position on the
seat during vehicle maneuvers and braking, which helps the
passenger sensing system
maintain the passenger airbag
status. See
“Seat Belts” and
“Child Restraints” in the Index
for additional information
about the importance of
proper restraint use.
A thick layer of additional
material, such as a blanket or
cushion, or aftermarket
equipment such as seat
covers, seat heaters, and seat
massagers can affect how well
the passenger sensing system
operates. We recommend that
you not use seat covers or
other aftermarket equipment
except when approved by GM
for your specific vehicle. See
Adding Equipment to the
Airbag-Equipped Vehicle 071
for more information about
modifications that can affect
how the system operates.
The ON indicator may be lit if
an object, such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device, is

72 Seats and Restraints
In addition, the vehicle has a
passenger sensing system for
the front outboard passenger
position, which includes
sensors that are part of the
passenger seat. The
passenger sensing system
may not operate properly if
the original seat trim is
replaced with non-GM covers,
upholstery, or trim; or with GM
covers, upholstery, or trim
designed for a different
vehicle. Any object, such as an
aftermarket seat heater or a
comfort-enhancing pad or
device, installed under or on
top of the seat fabric, could
also interfere with the
operation of the passenger
sensing system. This could
either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system
from properly turning off the
passenger airbag(s). See
Passenger Sensing System
066. If the vehicle has rollover
roof-rail airbags, see Different
Size Tires and Wheels
0352
for additional important
information.
If the vehicle must be modified
because you have a disability
and have questions about
whether the modifications will
affect the vehicle's airbag
system, or if you have
questions about whether the
airbag system will be affected
if the vehicle is modified for
any other reason, call
Customer Assistance. See
Customer Assistance Offices
0 386.
Airbag System Check
The airbag system does not
need regularly scheduled
maintenance or replacement.
Make sure the airbag
readiness light is working. See
Airbag Readiness Light 0112.
Caution
If an airbag covering is
damaged, opened, or broken,
the airbag may not work
properly. Do not open or
break the airbag coverings.
If there are any opened or
broken airbag coverings,
have the airbag covering
and/or airbag module
replaced. For the location of
the airbags, see Where Are
the Airbags? 061. See your
dealer for service.

Cooling System
It is not necessary to regularly
check coolant unless a leak is
suspected or an unusual noise
is heard. A coolant loss could
indicate a problem. Have it
inspected and repaired by
your dealer.
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 outside the
battery on a cradle, heats the
coolant until the correct
temperature is reached.
The cooling system allows the
vehicle to maintain the correct
working temperature.Checking Coolant
The coolant needs to be
replaced at the appropriate
interval. See Maintenance
Schedule
0376.
The coolant reservoir is in the
underhood compartment. See
Underhood Compartment
Overview 0312.
To access the coolant
reservoir under the hood, the
right side access cover needs
to be removed. 1. Park on a level surface and turn the vehicle off.
2. Open the hood. See Hood 0310.
3. The coolant reservoir is
under a cover and side
extension/shield in the
underhood compartment.
Unclip the right side of the
shield and remove the right
side access cover.
