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 a vehicle equipped with Keyless Enter-N-Go™
(if equipped) in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Turn the key fob to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key fob to the OFF position, wait five
seconds, then repeat the “Normal Starting” procedure.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting into any
driving range.
