remote start, but the column should
unlock after the brake pedal is
pressed and the vehicle is started.
No message will display during a
remote start.
.A message that the steering wheel
must be turned and the vehicle
must be started again indicates that
the column lock mechanism is
bound, the column locking device
was unable to unlock the steering
column, and the vehicle did not
start. If this happens, immediately
turn the steering wheel from side to
side to unbind the column lock.
If this does not unlock the steering
column, turn the vehicle off and

SEATS AND RESTRAINTS 47
Buckle To Drive
If equipped, this feature prevents the
vehicle from shifting out of P (Park)
when the driver seat belt is not
buckled. The Buckle to Drive feature
must be turned ON in the
infotainment system to work. See
Vehicle Personalization0123 and if
equipped, Teen Driver 0189. If the
engine is running, the driver seat belt
is not buckled, and the brake pedal is
pressed with the vehicle in P (Park), a
message displays in the Driver
Information Center (DIC). Buckle the
driver seat belt to shift out of P (Park).
Shifting from P (Park) will be
prevented once for each ignition cycle.
For some fleet vehicles, the feature is
always ON and it cannot be turned
OFF in the infotainment system.
Shifting from P (Park) will be
prevented each time the above
conditions exist.
On some models, Buckle to Drive may
also prevent shifting out of P (Park) if
a front passenger is unbuckled under
similar conditions. A message displays
in the DIC. Buckle the front passenger
seat belt to shift out of P (Park). This feature 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 passenger seat. If this
happens, remove the object from the
seat or buckle the seat belt to shift
out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains
unbuckled, the DIC message will turn
off after several seconds and the
vehicle can be shifted out of P (Park).
See
“Seat Belts” and“Child Restraints”
in the Index for information about the
importance of proper restraint use.
If the driver seat belt, and in some
vehicles the front passenger seat belt,
is unbuckled when driving, the seat
belt reminder chime and light(s) will
come on. See Seat Belt Reminders
0 101. This feature may not function
properly if the airbag readiness light is
on. See Airbag Readiness Light 0102.

Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the vehicle may affect vehicle operation.
See
Add-On Electrical Equipment 0307.
See your dealer if assistance is needed.
The vehicle may not pass
inspection if:
.The light is on when the engine is
running.
.The light does not come on when
the ignition is in Service Mode.
.Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
