Warning (Continued)
passengers to ride in any area of

reminder to buckle the seat belts.

Seat Belt Assurance System
This vehicle may have the Seat Belt
Assurance System, which prevents
the vehicle from shifting out of
P (Park). A message displays in the
Driver Information Center (DIC)
indicating the shift lever is locked
when the brake pedal is applied and
the seat belts for either the driver or
front outboard passenger are not
buckled. The vehicle will not shift
out of P (Park). Buckle the seat
belts to unlock the shift lever. If the
front passenger seat is unoccupied,
only the driver seat belt must be
buckled to unlock the shift lever.
This system may not allow the
vehicle to shift out of P (Park) if an
object
—
such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device
—
is on
the front outboard passenger seat.
If this happens, remove the object
from the seat or buckle the
seat belt.
If the driver or front outboard
passenger unbuckles their seat belt
while driving, the seat belt reminder
chime and light(s) will come on. See
The Seat Belt Assurance System
will time out 30 seconds after the
brake pedal is initially pressed.
A message displays in the DIC
indicating the shift lever is unlocked
allowing the vehicle to be shifted out
of P (Park). See
“
Seat Belts
”
and
“
Child Restraints
”
in the Index for
information about the importance of
proper restraint use.
This system may not function
properly if the airbag readiness light
is on. See
Why Seat Belts Work
When riding in a vehicle, you travel
as fast as the vehicle does. If the
vehicle stops suddenly, you keep
going until something stops you.
It could be the windshield, the
instrument panel, or the seat belts!
When you wear a seat belt, you and
the vehicle slow down together.
There is more time to stop because
you stop over a longer distance and,
when worn properly, your strongest
bones take the forces from the seat
belts. That is why wearing seat belts
makes such good sense.
