■Tire information
●Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm 2
or bar, 3 psi) greater than
the recommended value when towing. ( P. 629)
●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 any authorized Lexus retailer or Lexus authorized repairer, or any reli-
able repairer 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 systemand 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. 234)
●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).
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 damage. Apply a rust inhib-
itor to parts that will come in co ntact when attaching a steel bracket.

WARNING
■For your safety
●Please drive safely.
The function of this system is to assist you in making the Emergency Call in case of
accidents as traffic accidents or sudden medi cal emergencies, and it does not protect
the driver or the passengers in any way. Plea se drive safely and fasten your seatbelts
at all times for your safety.
●In case of an emergency, make lives the top priority.
●If you smell anything burning or another unus ual smell, do not stay inside the vehicle

●The airbag may not inflate even in case of an accident, if it does not involve high
impact. In such cases, the system may not make emergency calls automatically. The
system may also not make automatic emergency calls even if the airbag has been
inflated. If any of these should occur, plea se report to the Public Safety Answering
Point (PSAP) by operating the “SOS” button.
●For safety, do not make the Emergency Call while driving.
Making calls during driving may cause mish andling of the steering wheel, which may
lead to unexpected accidents.
Stop the vehicle and confirm the safety of the area before making the Emergency
Call.
●When changing fuses, please use fuses that correspond to the described standard.
If you use fuses other than those described, it may cause ignition or smoke in the cir-
cuit and may lead to a fire.
●Using the system while there is smoke or an unusual smell may cause a fire. Stop
using the system immediately and consult any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
