STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 15-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!
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 shift
lever. Do not leave the Key Fob in or near the vehicle,
or in a location accessible to children, and do not
(Continued)
WARNING!(Continued)
leave the ignition of a vehicle equipped with keyless
Enter-N-Go in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.

Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Cycle the ignition to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, cycle the ignition to the OFF position,
wait five seconds, then repeat the “Normal Starting”
procedure.
