• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up
may cause serious injury or death.
• When leaving the vehicle, always make
sure the keyless ignition node is in the
"OFF" mode, 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. Allow-
ing children to be in a vehicle unattended is
dangerous for a number of reasons. A child
or others could be seriously or fatally in-
jured. Children should be warned not to

dren, 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.
ENGINE BLOCK HEATER — IF
EQUIPPED
The engine block heater warms engine coolant
and permits quicker starts in cold weather. Con-
nect the heater cord to a ground-fault interrupter
protected 110–115 Volt AC electrical outlet with
a grounded, three-wire extension cord.
Its use is recommended for environments that
routinely fall below -10°F (-23°C). It should be
used when the vehicle has not been running for
long periods of time and should be plugged in
two hours prior to start. Its use is required for
cold starts with temperatures under -20°F
(-28°C).
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your autho-
rized dealer) is recommended.
