2324-1. Before driving
GS350_250_OM_OM30E16E_(EE)
■Tire information
●Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater
than the recommended value when towing. ( →P. 6 4 5 )
●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. 2 2 8 )
●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).

Driving
GS350_250_OM_OM30E16E_(EE)
Your vehicle will handle differently when towing a trailer. In order to avoid
accident, death or serious injury, keep the following in mind when towing:
■Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection between
the trailer and lights after driving for a brief period as well as before
starting off.
■Practicing driving with a coupled trailer
●Get the feel for turning, stopping and reversing with the trailer cou-
pled by practicing in an area with no or light traffic.
●When reversing with a coupled trailer, hold the section of the steer-
ing wheel nearest to you and rotate clockwise to turn the trailer left
or counterclockwise to turn it right. Always rotate a little at a time to
prevent steering error. Have someone guide you when reversing to
lessen the risk of an accident.
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 corro-
sion, which will weaken the section concerned and may result in damage. Apply a
rust inhibitor to parts that will come in contact when attaching a steel bracket.
