
Break-in schedule
Lexus recommends that vehicles fitted with new power train components
should not be used for towing trailers for the first 800 km (500 miles).

Maintenance

Maintenance must be performed more frequently when using the vehicle
for towing due to the greater weight burden placed on the vehicle com-
pared to normal driving.

Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).

Safety checks before towing

Check that the maximum load limit for the towing hitch/bracket hitch
ball is not exceeded. Bear in mind that the coupling weight of the trailer
will add to the load exerted on the vehicle. Also make sure that you will
not be towing a load that exceeds the maximum permissible axle capac-
ity.

Ensure that the trailer load is secure.

Supplementary outside rear view mirrors should be added to the vehicle
if the traffic behind cannot be clearly seen with standard mirrors. Adjust
the extending arms of these mirrors on both sides of the vehicle so that
they always provide maximum visibility of the road behind.
NOTICE

When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that
area.
When steel and aluminum come into contact, there is a reaction similar to
corrosion, which will weaken the section concerned which may result in
damage. Apply a rust inhibitor to parts that will come in contact when
attaching a steel bracket.

When installing a towing harness to the vehicle
To prevent inoperative stop lights and damage to the vehicle stop light wir-
ing, take care when connecting a trailer harness to the vehicle. A relay with
a separate power source must be added to limit the current draw on the vehi-
cle stop light wiring.
