HITCHES
D
Use only a weight carrying
designed for the total trailer weight.
Toyota does not recommend using a
weight distribution (load equalizing)
hitch.
D
The hitch must be bolted securely to
the vehicle frame and installed accord-
ing to the hitch manufacturer's instruc-
tions.
D
The hitch ball and king pin should have
a light coat of grease.
D
Toyota recommends removing the hitch
when not towing to prevent injury and/
or damage due to the hitch in event of
a rear end collision. After removal of
the hitch, seal the installation area to
prevent entry of exhaust fumes and
mud.
NOTICE
Do not use an axle−mounting hitch as
it may cause damage to the axle
housing, wheel bearings, wheels and
or tires.

BRAKES AND SAFETY CHAINS
D
hitch Toyota recommends
brakes that conform to any applica-
ble federal and state/provincial regu-
lations.
D
A safety chain must always be used
between the towing vehicle and the
trailer. Leave sufficient slack in the
chain for turns. The chain should
cross under the trailer tongue to
prevent the tongue from dropping to
the ground in case it becomes dam-
aged or separated. For correct safety
chain procedures, follow the hitch or
trailer manufacturer's
tions.
CAUTION
D
If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.
D
Never tap into your vehicle's hy-
draulic system as it would lower its
braking effectiveness.
