WARNING!
Do not leave children or animals inside

parked vehicles in hot weather. Interior

vehicle and lock the vehicle.
WARNING! (Continued)
Never leave children alone in a vehicle, or

with access to an unlocked vehicle.
Allowing children to be in a vehicle unat-
tended 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.
Do not leave the key fob in or near the

vehicle, or in a location accessible to chil-
dren, and do not leave the ignition of a
