Warning
You or others could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
Caution
To avoid damage to the liftgate or
liftgate glass, make sure the area
above and behind the liftgate is
clear before opening it...
If equipped, when the vehicle is
shifted into R (Reverse), RCTA
displays a red warning triangle with
a left or right pointing arrow to warn
of traffic coming from the left or

coming from up to 20m (65 ft) from
the left or right side of the vehicle...
