IS300h_EE(OM53D89E)
■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 or wireless remote control will re-enable
the intrusion sensor and tilt sensor.
●The intrusion sensor and tilt sensor will au tomatically be re-enabled when the alarm system is deactivated.
■Intrusion sensor detection considerations
The sensor may trigger the alar m 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 on a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed • When the vehicle is in an auto matic 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 follow- ing:
• 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 vehi-
cles • The movement of peop le outside the vehi-
cle
●Unstable items, such as dangling accessories
or clothes hanging on the coat hooks, are in the vehicle.

■When starting off on an uphill
The hill-start assist control will activate. ( P. 352)
■For fuel-efficient driving
Keep in mind that hybrid vehicles are simila r to conventional vehicles, and it is necessary
to refrain from activities su ch as sudden acceleration. (P. 358)
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows may
become fogged-up, and th e road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially slip- pery.
●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 surface, preventing the steering and brakes from operating properly.
■Restraining the hybrid system ou tput (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the hybrid sys- tem output may be restrained.
●A warning message is displaye d on the multi-information display while the system is
operating. If a warning message is shown on the multi-information display, read the message and follow the instructions.
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is performed, the engine output may be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D
includes S) with the acce lerator pedal depressed, a warning message appears on the multi-information display. ( P. 595)
• When the accelerator pedal is depressed t oo much while the vehicle is in reverse.
●While Drive-Start Control is being activated, your vehicle may have trouble escaping
from the mud or fresh snow. In such case, deactivate TRC ( P. 354) to cancel Drive-
Start Control so that the vehicle may become able to escape from the mud or fresh snow.
■Breaking in your new Lexus
To extend the life of the vehicle, observin g the following precautions is recommended:
●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 a towing package)
Lexus does not recommend towing a trailer with your vehicle. Lexus also does
not recommend the installation of a to w hitch or the use of a tow hitch carrier
for a wheelchair, scooter, bicycle, etc. Yo ur vehicle is not designed for trailer
towing or for the use of to w hitch mounted carriers.

◆Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle Mass), MPAC
(Maximum Permissible Axle Capacity), and permissible draw bar load before
towing. ( P. 644)
◆Towing hitch/bracket
Lexus recommends the use of the Lexus hi tch/bracket for your vehicle. Other
products of a suitable nature and comparable quality may also be used.
◆To prevent an accident
The handling of the vehicle will feel diff erent when towing a trailer. Beware of
the 3 most common causes of towing-rel ated accidents: driver error, exces-
sive speed, and overloading.
Trailer towing (vehicles with a towing package)
The strain of towing a trailer will have a negative impact on the running perfor-
mance, 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. Dama ge and/or malfunctions that occur as
a result of towing performed for comme rcial purposes are not covered by the
Lexus warranty.
Ask your local authorized Lexus retailer or Lexus authorized repairer, or any
reliable repairer for furthe r details before towing, as there are additional legal
requirements in some countries.

■Total trailer weight and permissible drawbar load
Total trailer weight
Weight of the traile r itself plus the trailer load should be within the max-
imum towing capacity. Exceeding
this weight is dangerous. ( P. 644)
When the total trailer weight is
greater than the vehicle weight, we
recommend the use of a friction sta- bilizer (sway control device).
Permissible drawbar load
Allocate the trailer load so that the drawba r load is greater than 25 kg (55.1 lb.) or
4% of the towing capacity. Do not let the drawbar load exceed the indicated weight. ( P. 644)
■Information tag (manufacturer’s label)
Gross vehicle mass
The combined weight of the driver, passengers, luggage, towing hitch, total curb
mass and drawbar load should not exceed the gross vehicle mass by more than
100 kg (220.5 lb.). Exceedin g this weight is dangerous.
Maximum permissible rear axle capacity
The weight borne by the rear axle should not exceed the maximum permissible
rear axle capacity by 15% or more. Exceeding this weight is dangerous.
The values for towing capacity were derived from testing conducted at sea level. Take note that engine output and towing capacity will be reduced at high altitudes.

WARNING
■When the gross vehicle mass or maximum permissible axle capacity is exceeded
Failing to observe this precau tion may lead to an accident causing death or serious
injury.
●Add an additional 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) to the recommended tire infla- tion pressure value. ( P. 652)
●Do not exceed the established speed limit for towing a trailer in built-up areas or 100
km/h (62 mph), whic hever is the lower.

■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. 652)
●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 shou ld be added to the vehicle if the traffic behind cannot be clearly seen with standa rd 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 contact when attaching a steel bracket.
