Warning
Make sure there is no one in the way of the power tailgate as it is opening
and closing, and keep hands away from the tailgate hinges when in use. You or others
could be injured if caught in the path of the power tailgate or tailgate hinges...
The Keyless Access system allows for doors and the tailgate to be accessed without
pressing the RKE transmitter button. The RKE transmitter must be within 1m (3 ft)
of the tailgate or door being opened. If the vehicle has this feature, there will
be a button on the outside door handles...

If equipped, there is a small convex mirror built into the upper and outer corner
of the driver outside mirror. It can show objects that may be in the vehicle's blind
zone.
Driving with the Blind Spot Mirror

Actual Mirror View
When the approaching vehicle is a long distance away, the image in the main
mirror is small and near the inboard edge of the mirror.
As the vehicle gets closer, the image in the main mirror gets larger and
moves outboard.
As the vehicle enters the blind zone, the image transitions from the main
mirror to the blind spot mirror.
When the vehicle is in the blind zone, the image only appears in the blind
spot mirror.
