by illuminating the low tire pressure
warning light on the instrument
cluster. If the warning light comes
on, stop as soon as possible and
inflate the tires to the recommended
pressure shown on the tire loading
information label located on the
driver side center pillar (B pillar).
See Vehicle Load Limits
on
page 9‑27. The warning light will
remain on until the tire pressure is
corrected. You may notice during cooler
conditions that the low tire pressure
warning light will appear when the
vehicle is first started and then

an early indicator that your tire
pressures are getting low and the
tires need to be inflated to the
proper pressure.
The Tire Pressure Monitor System
can alert you about low tire
pressure, but it does not replace
normal monthly tire maintenance.
It is the driver
’s responsibility to
maintain correct tire pressures.

OnStar service cannot work unless
the vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area. OnStar service also
cannot work unless the vehicle is
in a place where the wireless
service provider OnStar has hired
for that area has coverage, network
capacity and reception when the
service is needed, and technology
that is compatible with the OnStar
service. Not all services are
available everywhere, particularly
in remote or enclosed areas, or at
all times.
The OnStar system can record and
transmit vehicle information. This
information is automatically sent to
an OnStar call center when
Qis

]is pressed, or if the
airbags or ACR system deploy.
This information usually includes
the vehicle's GPS location and, in
the event of a crash, additional
information regarding the crash that
the vehicle was involved in (e.g. the
direction from which the vehicle was
hit). When the virtual advisor feature
of OnStar hands-free calling is
used, the vehicle also sends OnStar
the vehicle's GPS location so they
can provide services where it is
located.
Location information about the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.
