STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the Key Fob
from the vehicle, and lock the vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children 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 trans-
mission gear selector.
(Continued)
WARNING!(Continued)
•Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children), and do not

Keyless Enter-N-Go™) in the ACC or ON/RUN
mode. A child could operate power windows, other
controls, or move the vehicle.
