Trunk pass-through hatch
A trunk pass-through hatch is incorporated in the rear seat backrest
to enable long, narrow items to be carried inside the car.
Items should not weigh more than 33 lbs. (15 kg) nor be more than
2 yards (2 metres) in length. See the label on the hatch.
1 Fold down the armrest.
2 Raise the hatch by lifting the handle.
Before loading or unloading long items, switch off the engine and
apply the handbrake. This averts the danger of the car moving off
suddenly if a long item were to knock the gear or selector lever into
gear.
• Anchor the load securely (e.g. using middle safety belt) to
avoid danger of injury resulting from displacement of load on
hard braking.
• Do not exceed the load capacity of the car, as this will alter its
handling characteristics (see page 258).
Tie Downs
Four tie downs for securing the load are fitted inside the trunk. Place
the load as far in as possible.
