HITCHES
D
If you wish to install a trailer hitch, you
should consult with your Toyota dealer.
D Use only a hitch recommended by the
hitch manufacturer and the one which
conforms to the total trailer weight re-
quirement.
D According to the hitch receiver type,
the maximum gross trailer weight and
hitch that can be used differs. Refer to
the above illustrations to confirm the
hitch receiver type for your vehicle.
D
If you wish to install an aftermarket
hitch, the hitch must be bolted securely
to the vehicle frame and installed ac-
cording to the hitch manufactures' in-
structions.
D The hitch ball and king pin should have
a light coat of grease.
D
Toyota recommends the ball mount as-
sembly be removed when not towing to
prevent injury and to prevent damage
in the event of a rear end collision.
After removing the ball mount assem-
bly, install the grommet to the hitch to
prevent entry of dirt and mud.
CAUTION
Do not tow the vehicle using the
hooked portion of the weight carrying
hitch. The hooked portion may break
and cause serious injury or damage
to the vehicle.
NOTICE
z Do not install weight distributing
hitch to weight carrying hitch re-
ceiver because it will be damaged
your vehicle.
z Do not use axle- mounted hitches as
they can cause damage to the axle
housing, wheel bearings, wheels or
tires. Also, never install a hitch
which may interfere with the normal
function of an Energy Absorbing
Bumper, if so equipped.
