Tire information
■
Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm
●
than the recommended value when towing. (→P. 645)
Increase the air pressure of the trailer tires in accordance with the total trailer
●
weight and according to the values recommended by the manufacturer of your
trailer.
Trailer lights
■
Please consult at any authorized dealer or repairer, or another duly qualified 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.
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.
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 and 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 the total load exerted on the vehicle is
within the range of the weight limits. (→P. 228)
Ensure that the trailer load is secure.
●
Supplementary outside rear view mirrors should be added to the vehicle if the traf-
●
fic 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 tow-
●
ing due to the greater weight burden placed on the vehicle compared to normal
driving.
Retighten all bolts securing the hitching ball and bracket after towing for approxi-
●
mately 1000 km (600 miles).
