GS450h_300h_OM_OM30D53E_(EE)
For safety and security
Canceling and automatic re-enabling of the intrusion sensor and tilt sensor
The alarm will still be set even when the intrusion sensor and tilt sensor are
canceled.
After the intrusion sensor and tilt sensor are canceled, pressing the power
switch or unlocking the doors using the entry function, wireless remote con-
trol or mechanical key will re-enable the intrusion sensor and tilt sensor.
The intrusion sensor and tilt sensor will automatically be re-enabled when
the alarm system is deactivated.
Intrusion sensor detection considerations
The sensor may trigger the alarm in the following situations:
Places with extreme vibrations or noises, or situations in which the vehicle
is subject to repeated impacts or vibrations:
• When parked in a parking garage
• When the vehicle is transported by a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed
• When the vehicle is in an automatic or high-pressure car wash
• When in a hail or lightning storm
A window or the moon roof is open.
In this case, the sensor may detect the
following:
• Wind or the movement of objects
such as leaves and insects inside the
vehicle
• Ultrasonic waves emitted from
devices such as the intrusion sensors
of other vehicles
• The movement of people outside the
vehicle
Unstable items, such as dangling acces-
sories or clothes hanging on the coat
hooks, are in the vehicle.

GS450h_300h_OM_OM30D53E_(EE)
Tilt sensor detection considerations (if equipped)
The sensor may trigger the alarm in the following situations:
The vehicle is transported by a ferry, trailer, train, etc.
The vehicle is parked in a parking garage.
The vehicle is inside a car wash that moves the vehicle.
Any of the tires loses air pressure.
The vehicle is jacked up.
An earthquake occurs or the road caves in.
NOTICE
To ensure the intrusion sensor function correctly
Installing accessories other than genuine Lexus parts or leaving objects
between the driver’s seat and front passenger’s seat may reduce the detec-
tion performance.
To ensure that the sensors operate prop-
erly, do not touch or cover them.
Do not spray air fresheners or other
products directly into the sensor holes.

2264-1. Before driving
GS450h_300h_OM_OM30D53E_(EE)
Make sure that the parking brake is set and shift the shift lever to
D.
Gently depress the accelerator pedal.
Release the parking brake.
When starting off on a uphill
The brake hold is available. (P. 269)
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the
windows may become fogged-up, and the road will be slippery.
Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is rec-
ommended:
For the first 300 km (186 miles):
Avoid sudden stops.
For the first 800 km (500 miles):
Do not tow a trailer.
For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.

Trailer towing (vehicles without towing package)
Lexus does not recommend towing a trailer with your vehicle.
Lexus also does not recommend the installation of a tow hitch or
the use of a tow hitch carrier for a wheelchair, scooter, bicycle, etc.
Your vehicle is not designed for trailer towing or for the use of tow
hitch mounted carriers.

2384-1. Before driving
GS450h_300h_OM_OM30D53E_(EE)
Trailer towing (vehicles with towing package)
Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle
Mass), MPAC (Maximum Permissible Axle Capacity), and per-
missible draw bar load before towing. (P. 926)
Towing hitch/bracket
Lexus recommends the use of the Lexus hitch/bracket for your
vehicle. Other products of a suitable nature and comparable qual-
ity may also be used.
To prevent an accident
The handling of the vehicle will feel different when towing a
trailer. Beware of the 3 most common causes of towing-related
accidents: driver error, excessive speed, and overloading.
The strain of towing a trailer will have a negative impact on the
running performance, handling, fuel consumption and endurance
of your vehicle. Use the vehicle features in the correct manner and
operate the vehicle with care for safer driving and optimal comfort.
Damage and/or malfunctions that occur as a result of towing per-
formed for commercial purposes are not covered by the Lexus war-
ranty.
Ask your local authorized Lexus dealer or repairer, or another duly
qualified and equipped professional for further details before tow-
ing, as there are additional legal requirements in some countries.

GS450h_300h_OM_OM30D53E_(EE)
Total trailer weight and permissible drawbar load
Total trailer weight
Weight of the trailer itself plus
the trailer load should be within
the maximum towing capacity.
Exceeding this weight is dan-
gerous. (P. 926)
When the total trailer weight is
greater than the vehicle weight,
we recommend the use of a fric-
tion stabilizer (sway control
device).
Permissible drawbar load
Allocate the trailer load so that
the drawbar load is greater than
25 kg (55.1 lb.) or 4% of the
towing capacity. Do not let the
drawbar load exceed the indi-
cated weight. (P. 926)
Important points regarding trailer loads

2404-1. Before driving
GS450h_300h_OM_OM30D53E_(EE)
Information tag (manufacturer’s label)
Gross vehicle mass
The combined weight of the
driver, passengers, towing hitch,
total curb mass and drawbar
load should not exceed the gross
vehicle mass by more than 100
kg (220.5 lb.). Exceeding this
weight is dangerous.
Maximum permissible rear
axle capacity
The weight borne by the rear
axle should not exceed the max-
imum permissible axle capacity
by 15% or more. Exceeding this
weight is dangerous.
The values for towing capacity
were derived from testing con-
ducted at sea level. Take note
that engine output and towing
capacity will be reduced at high
altitudes.

CAUTION
When the gross vehicle mass limit or maximum permissible axle capacity is
exceeded
Do not exceed the established speed limit for towing a trailer in built-up
areas or 100 km/h (62 mph), whichever is the lower.

Driving
GS450h_300h_OM_OM30D53E_(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. 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).
