IS300h_EE(OM53B95E)
CAUTION
Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious
injury.
Remove any heavy loads, such as snow and ice, from the trunk lid before
opening it. Failure to do so may cause the trunk lid to suddenly shut again
after it is opened.
When opening or closing the trunk lid, thoroughly check to make sure the sur-
rounding area is safe.
If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
Use caution when opening or closing the trunk lid in windy weather as it may
move abruptly in strong wind.
Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on the trunk lid may cause the lid to suddenly shut
again after it is opened.
The trunk lid may suddenly shut if it is
not opened fully. It is more difficult to
open or close the trunk lid on an incline
than on a level surface, so beware of the
trunk lid unexpectedly opening or closing
by itself. Make sure that the trunk lid is
fully open and secure before using the
trunk.
When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When the vehicle is stopped
Do not depress the accelerator pedal unnecessarily.
If the shift lever is any position other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.
In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indicator on,
and apply the parking brake as necessary.
If the vehicle is stopped on an incline, in order to prevent accidents caused by
the vehicle rolling forward or backward, always depress the brake pedal and
securely apply the parking brake as needed.
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible mate-
rial is nearby.
When the vehicle is parked
Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic
material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior
of the vehicle, and may also cause a short circuit in the vehicle’s electrical
components.
Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place
such as the glove box or on the floor, it may be lit accidentally when luggage
is loaded or the seat is adjusted, causing a fire.
Do not attach adhesive discs to the windshield or windows. Do not place con-
tainers such as air fresheners on the instrument panel or dashboard. Adhesive
discs or containers may act as lenses, causing a fire in the vehicle.
Do not leave a door or window open if the curved glass is coated with a met-
allized film such as a silver-colored one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.
Always apply the parking brake, shift the shift lever to P, stop the hybrid sys-
tem and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system is operating.
Do not touch the exhaust pipes while the hybrid system is operating or imme-
diately after turning the hybrid system off.
Doing so may cause burns.

IS300h_EE(OM53B95E)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or fire
due to hybrid system overheating. Additionally, if the vehicle is parked in a
poorly ventilated area, exhaust gases may collect and enter the vehicle, leading
to death or a serious health hazard.
When braking
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one
side of the vehicle to brake differently than the other side. Also, the parking
brake may not securely hold the vehicle.
If the electronically controlled brake system does not operate, do not follow
other vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase. Have your
brakes fixed immediately.
The brake system consists of 2 or more individual hydraulic systems; if one of
the systems fails, the other(s) will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. Have your brakes fixed immediately.

Cargo and luggage
Take notice of the following information about storage precautions,
cargo capacity and load:
CAUTION
Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk:
Receptacles containing gasoline
Aerosol cans
Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly, may
block the driver’s vision, or may result in items hitting the driver or passengers,
possibly causing an accident.
Stow cargo and luggage in the trunk whenever possible.
To prevent cargo and luggage from sliding forward during braking, do not
stack anything in the enlarged trunk. Keep cargo and luggage low, as close to
the floor as possible.
When you fold down the rear seats, long items should not be placed directly
behind the front seats.
Never allow anyone to ride in the enlarged trunk. It is not designed for pas-
sengers. They should ride in their seats with their seat belts properly fastened.
Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
• On the dashboard
• In front of the navigation system screen (if equipped) or Lexus Display
Audio screen (if equipped)
Secure all items in the occupant compartment.
Load and distribution
Do not overload your vehicle.
Do not apply loads unevenly.
Improper loading may cause deterioration of steering or braking control
which may cause death or serious injury.

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. 570)
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.
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 towing 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 extend-
ing arms of these mirrors on both sides of the vehicle so that they always pro-
vide 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 nor-
mal 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 cor-
rosion, 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.
