Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician should
connect equipment to the OBD II connection
port in order to read the VIN, diagnose, or
service your vehicle.
If unauthorized equipment is connected to the
OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access, infor-
mation stored in your vehicle systems,
including personal information.

Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans-
mission into PARK and apply the parking
brake.
Always make sure the keyless ignition node is
in the OFF position, key fob is removed from
the vehicle and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren in a vehicle unattended is dangerous for
a number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the gear selector.
WARNING!
