Operation of each component
GS450h_300h_OM_OM30D53E_(EE)
Note for the push-start function
Even when the electronic key is within the effective range (detection areas),
the system may not operate properly when the electronic key is on the
instrument panel, rear package tray or floor, or in the door pockets or glove
box when the hybrid system is started or power switch modes are changed.
Even if the electronic key is not inside the vehicle, it may be possible to
start the hybrid system if the electronic key is near the window.
When the vehicle is not driven for extended periods
Vehicles with entry function: To prevent theft of the vehicle, do not leave
the electronic key within 2 m (6 ft.) of the vehicle.
The smart entry & start system can be deactivated in advance. (P. 942)
Alarm (if equipped)
Using the smart entry & start system to lock the doors will set the alarm sys-
tem.
(P. 97)
To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention function
may not operate.)
Do not leave the electronic key inside the luggage compartment.
The key confinement prevention function may not operate, depending on
the location of the key (close to a spare tire [if equipped], the inside edge of
the luggage compartment), conditions (inside a metal bag, close to metallic
objects) and the radio waves in the surrounding area. (P. 189)
If the smart entry & start system does not operate properly
Locking and unlocking the doors and opening the trunk: Use the mechani-
cal key.
(P. 908)
Starting the hybrid system: P. 9 0 9

Driving
GS450h_300h_OM_OM30D53E_(EE)
If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If
the engine coolant temperature gauge indicates that the engine is
overheating, turn the air conditioning off immediately, leave the
road and stop the vehicle in a safe place. (P. 915)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever
to P.
CAUTION
To avoid accident or injury
Do not tow a trailer when the compact spare tire is installed on your vehi-
cle.
Do not tow a trailer when the tire installed is repaired with the emergency
tire puncture repair kit.
Do not use cruise control (if equipped) or dynamic radar cruise control (if
equipped) when trailer towing.
Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while
descending steep or long downhill grades.
Operation of the brake pedal
Do not hold the brake pedal depressed often or for long periods of time.
Doing so may result in the brake overheating or reduce braking effects.

3464-5. Using the driving support system
GS450h_300h_OM_OM30D53E_(EE)
CAUTION
Situations unsuitable for LKA
Do not use LKA in any of the following situations.
Otherwise, the system may not function correctly and could result in an
accident.
When driving with snow tires, tire chains, a spare tire, or similar equip-
ment
When the tires have been excessively worn, or when the tire inflation
pressure is low
When there are objects or structures along the roadside that might be mis-
interpreted as lane markers (such as guardrails, curb, reflector posts, etc.)
When driving on snowy roads
When pavement lane markers are difficult to see due to rain, snow, fog,
sand, dirt, etc.
When there are visible lines on the pavement from road repairs, or if the
remains of old lane markers are still visible on the road
When driving on slippery roads, such as those covered with rain, ice or
snow
When driving in a lane other than the driving or passing lanes on a free-
way or highway
When driving on a road with lane closures due to maintenance, or when
driving in a temporary lane
When towing a trailer
NOTICE
To prevent damage to or incorrect operation of the LKA system
Do not modify the headlights or attach stickers to the surface of the lights.
Do not modify the suspension, or replace them with non-genuine parts.
Do not install or place anything on the hood or the grille. Also, do not
install a grille guard (bull bars, kangaroo bar etc.).
Do not modify the sun visor or replace it with anything other than a genu-
ine Lexus product.

GS450h_300h_OM_OM30D53E_(EE)
CAUTION
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dan-
gerous handling characteristics, which may lead to an accident resulting in
death or serious injury.
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
Do not use tire sizes other than those recommended by Lexus.
Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
Vehicles with an emergency tire puncture repair kit (if equipped): Do not
tow anything if a tire that has been repaired using the emergency tire
puncture repair kit is installed. The load on the tire may cause unexpected
damage to the tire.
When initializing the tire pressure warning system (vehicles with the tire
pressure warning system)
Do not operate the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or
it may come on when the tire inflation pressure is actually normal.

Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width
and inset
*.
Replacement wheels are available at any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
*: Conventionally referred to as “off-
set”.
Lexus does not recommend using the following:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straightened
Steel wheels (except for vehicles with a steel spare wheel)
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or cause
a loss of handling control.

Maintenance and care
GS450h_300h_OM_OM30D53E_(EE)
Use only Lexus wheel nuts and wrenches designed for use with
your aluminum wheels.
When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1600 km (1000 miles).
Be careful not to damage the aluminum wheels when using tire
chains.
Use only Lexus genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.
When replacing wheels (vehicles with the tire pressure warning system)
The wheels of your vehicle are equipped with tire pressure warning valves
and transmitters that allow the tire pressure warning system to provide
advance warning in the event of a loss in tire inflation pressure. Whenever
wheels are replaced, tire pressure warning valves and transmitters must be
installed. (P. 756)
Aluminum wheel precautions
CAUTION
When replacing wheels
Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in a loss of handling control.
Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
Do not install steel wheels.
The wheel contact surface could be damaged, and the wheel could come
off while driving, which could lead to an accident resulting in death or
serious injury. (except for vehicles with a steel spare wheel)
Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
