2-5. Driving information

Tire information

Ensure that your vehicle's tires are properly inflated. Adjust the tire pres-
sure to the recommended pressure. (P. 633)

Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the values recommended by the manufac-
turer of your trailer.

Trailer lights

Check that the turn signal lights and stoplights are operating correctly
every time you hitch up the trailer. Directly wiring up to your vehicle
may damage the electrical system and stop the lights from functioning
correctly.

Please consult at any authorized dealer or repairer, or another duly quali-
fied and equipped professional when installing trailer lights, as incorrect
installation may cause damage to the vehicle's lights. Please take care to
comply with your state's laws when installing trailer lights.

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).

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.

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).
