shift forward and come into
the passenger area, injuring
you and others. If you put
things in the bed of your truck,
you should make sure they
are properly secured.
Caution
Overloading the vehicle may
cause damage. Repairs would not
be covered by the vehicle
warranty. Do not overload the
vehicle.
Using heavier suspension
components to get added
durability might not change the
weight ratings. Ask your dealer
to help load the vehicle the
right way.
Warning
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
Put things in the cargo
area of the vehicle. Try to
spread the weight evenly.
Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
Do not leave an
unsecured child restraint
in the vehicle.
When you carry
something inside the
vehicle, secure it
whenever you can.
Do not leave a seat
folded down unless you
need to.
There is also important loading
information for off-road driving in
this manual. See Loading the
Vehicle for Off-Road Driving
under Off-Road Driving 0 242.
Two-Tiered Loading
Depending on the model of the
pickup, an upper load platform
can be created by positioning
three or four 5 cm (2 in) by
15 cm (6 in) wooden planks
across the width of the pickup
box. The planks must be
inserted in the pickup box
depressions.
When using this upper load
platform, be sure the load is
securely tied down to prevent it
from shifting. The load's center
of gravity should be positioned
in a zone over the rear axle. The
zone is located in the area
between the front of each wheel
well and the rear of each wheel
