40 Opening and closing
& WARNING
-Never close the rear lid inattentively or
without checking first. Although the
closing force of the rear lid is limited,
you can still seriously injure yourself or
others.
-Always ensure that no one is within
range of the rear lid when it is moving, in
particular close to the hinges and the up­
per and lower edges -fingers or hands
can be pinched.
- To help prevent poisonous exhaust gas
from being drawn into the vehicle, al­
ways keep the rear lid closed while driv­ ing. Never transport objects larger than
those which fit completely into the lug­ gage area, because then the rear lid can­
not be fully closed .
- Never leave your vehicle unattended es­ pecially with the rear lid left open. A
child could crawl into the car through the
luggage compartment and pull the lid
shut, becoming trapped and unable to get out . To reduce the risk of personal in­
jury, never let children play in or around
your vehicle . Always keep the rear lid as
well as the vehicle doors closed when not in use.
- If there is a luggage rack or bicycle rack
mounted on the rear lid, it may not be
able to open completely or an opened rear lid may close by itself because of the
added weight . So the open rear lid must
be supported or the weight must be re­
moved from the luggage rack first .
(D Tips
-When the vehicle is locked, the rear lid
can be unlocked separately by pressing
the button
~ on the master key. When
the rear lid is closed again, it locks auto­
matically .
- The following applies to vehicles equip­
ped with the convenience key* feature: if
the remote control key is left in the lug­
gage compartment, luggage compart­
ment will automatically unlock itself af- ter you
lock the vehicle. This prevents
you from unintentionally locking your
key in the luggage compartment.
- If the vehicle battery charge drops be­
low a certain level, you can still open or
close the rear lid manually, however, you
will need to apply more force to close it.
