Driving

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. 936)
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
Please consult at any authorized dealer or repairer, or another duly qualified
and equipped professional when installing trailer lights, as incorrect instal-
lation 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 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 tow-
ing a load that exceeds the maximum permissible axle capacity.
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 compared
to normal driving.
Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).

2444-1. Before driving
GS450h_300h_OM_OM30D53E_(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
coupled by practicing in an area with no or light traffic.
When reversing with a coupled trailer, hold the section of the
steering 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
corrosion, which will weaken the section concerned and may result in dam-
age. Apply a rust inhibitor to parts that will come in contact when attaching
a steel bracket.

has been exceeded. Do not use the system when stopped on a slippery road.
NOTICE
When parking the vehicle
The brake hold system is not designed for use when parking the vehicle for
