hicle and/or its systems, including entrap-
ment in windows or inadvertent door lock
activation, do not leave children, people
who require the assistance of others or
pets unattended in your vehicle. Addition-
ally, the temperature inside a closed vehicle
on a warm day can quickly become high
enough to cause a significant risk of injury
or death to people and pets.
CAUTION
When the Intelligent Key battery is dis-
charged or other strong radio wave
sources are present near the operating lo-
cation, the Intelligent Key operating range
becomes narrower, and the Intelligent Key
may not function properly.
The Remote Engine Start function can only
be used when the Intelligent Key is within the
specified operating range from the vehicle.
The Remote Engine Start operating range is
approximately 197 ft (60 m) from the vehicle.

nience feature and is not a substitute for
proper vehicle operation because it has
areas where objects cannot be viewed.
The four corners of the vehicle in particu-
lar, are areas where objects do not al-
ways appear in the bird’s-eye, front, or
rear views. Always check your surround-
ings to be sure that it is safe to move
before operating the vehicle. Always op-
erate the vehicle slowly.
