Seats and storage
- Use the tie-down eyelets to secure your cargo properly
=> fig. 89 -arrows-.
Read and heed all WARNINGS=>
page 199, "Stowing
luggage".
In a collision, the laws of physics mean that even smaller items that
are loose in the vehicle will turn into heavy missiles that can cause
serious injury. Items in the vehicle pick up kinetic energy which
varies w ith the vehicle and the weight of the item. Vehicle speed is
the most significant factor.
For example , in a frontal collision a t a speed of 30 mph (48 km/h),
the forces acting on a 10 -lb (4.5 kg) object are about
20 times the
normal weight of the item . This means that the weight of the item
would suddenly be the equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an item of that weight flying freely
through the passenger compartment can cause in a collision at a
speed considered relatively low .
& WARNING
Weak, damaged or improper straps used to secure items to tie­
downs can fail during hard braking or in a collision and cause
serious personal injury.
• Always use suitable retaining straps and properly secure items
to the tie-downs in the luggage compartment to help prevent
items from shifting or flying forward.
• When the rear seat backrest is folded down, always use suit­
able retaining straps and properly secure items to the tie-downs in
the luggage compartment to help prevent items from flying
forward into the passenger compartment.
• Never attach a child safety seat tether strap to a tie-down. •
App lies to veh ic les: with cargo net
