low temperatures
Allow the interior of the vehicle to
warm up before using the liquid
crystal information display. At
extremely low temperatures, the

sive engine braking and possibly
an accident resulting in death or
injury.

WARNING
■Back door closer
●In the event that the back door
is left slightly open, the back
door closer will automatically
close it to the fully closed posi-
tion. It takes several seconds
before the back door closer

sure they are safe and let them
know that the back door is
about to open or close.
●If the power back door system is
turned off while the back door is
operating automatically, the
automatic operation is stopped.
The back door then has to be
operated manually. Take extra
care when on an incline, as the
