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 10-second
intervals. Waiting a few seconds between such intervals
will protect the starter from overheating.
WARNING!
•When leaving the vehicle, always make sure the
keyless ignition node is in the OFFmode, 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. Allowing children to
be 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.
(Continued)
WARNING! (Continued)
•Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not 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.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
Normal Starting
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.
