Driving
IS300h_EE(OM53D89E)
■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.

2164-1. Before driving
IS300h_EE(OM53D89E)
Your vehicle will handle differently when towing a trailer. In order to avoid acci-
dent, death or serious injury, keep the following in mind when towing:
■Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection between the
trailer and lights after driving for a brief period as well as before starting off.
■Practicing driving with a coupled trailer
●Get the feel for turning, stopping and reversing with the trailer coupled by
practicing in an area with no or light traffic.
●When reversing with a coupled traile r, hold the section of the steering
wheel nearest to you and rotate clockwis e to turn the trailer left or counter-
clockwise to turn it right. Always rotate a little at a time to prevent steering
error. Have someone guide you when reversing to lessen the risk of an
accident.
■Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the di stance to the vehicle running ahead of
you should be equivalent to or greater than the combined length of your vehi-
cle and trailer. Avoid sudden braking th at may cause skidding. Otherwise, the
vehicle may spin out of control. This is especially true when driving on wet or
slippery road surfaces.
■Sudden acceleration/steering input/cornering
Executing sharp turns when towing may re sult in the trailer colliding with your
vehicle. Decelerate well in advance when approaching turns and take them
slowly and carefully to avoid sudden braking.
■Important points regarding turning
The wheels of the trailer will travel closer to the inside of the curve than the
wheels of the vehicle. To make allowance for this, take the turns wider than you
would normally do.

Louder
Lower
When the dial is turned to the lowest
volume, driving sound will be turned off
and the indicator will go off.
■ASC is enabled when
The vehicle is being driven in normal mode or sport mode. ( P. 348)
■Situations that may disable the ASC system
The ASC system may be disabled depending on the driving conditions, such as when the
tires slip due to sudden acceleration.
ASC (Active Sound Control)
: If equipped
The ASC system is an electronic soun d system that generates driving sound,
conveying the kinetic situations of the vehicle’s acceleration and deceleration
to the driver through the speakers behi nd the instrument panel. The vehicle’s
response to the driver’s acceleration behavior and shift operations are also
conveyed in sound. When sport mode is selected, the sound conveyed to the
driver will be louder.

Lexus Safety System+
: If equipped
The Lexus Safety System+ consists of the following drive assist systems and
contributes to a safe and co mfortable driving experience:
WARNING
■Lexus Safety System+
The Lexus Safety System+ is designed to operate under the assumption that the driver
will drive safely, and is designed to help reduce the impact to the occupants and the vehicle in the case of a collision or assist the driver in normal driving conditions.
As there is a limit to the degree of reco gnition accuracy and control performance that
this system can provide, do not overly rely on this system. The driver is always responsi- ble for paying attention to the vehicl e's surroundings and driving safely.

2584-5. Using the driving support systems
IS300h_EE(OM53D89E)
The pre-collision system is equipped with a sophisticated computer that will
record certain data, such as:
• Accelerator status
•Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distance an d relative speed between your vehicle
and the vehicle ahead or other objects)
The pre-collision system does not record conversations, sounds or pictures.
●Data usage
Lexus may use the data recorded in this computer to diagnose malfunctions,
conduct research and develo pment, and improve quality.
Lexus will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if
the vehicle is leased
• In response to an official request by the police, a court of law or a govern-
ment agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or
vehicle owner
