Driving
■When starting off on a uphill
The hill-start assist control will activate. (P. 2 7 2 )
■For fuel-efficient driving
Keep in mind that hybrid vehicles are similar to conventional vehicles, and it is necessary
to refrain from activities such as sudden acceleration. ( P. 2 7 8 )
■Driving in the rain or adverse weather conditions
●Drive carefully, because visibility may be reduced, the windows may become fogged-
up, and the road will be slippery.
●Drive carefully when it gets we t or icy, because the road surface will be especially slip-
pery.
●Slow down when water is present on the roadway, 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 output (Brake Override System)
●When the accelerator and brake pedals are de pressed at the same time, the hybrid sys-
tem output may be restrained.
●A warning message is displayed 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.
■Breaking in your new Lexus
To extend the life of the ve hicle, observing the followin g precautions is recommended:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• 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.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes periodically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding down
operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehi cle registration laws and confirm the availability of the cor-
rect fuel. ( P. 5 4 3 )
■Eco-friendly driving

Driving
■S mode
●When the shift range is 4 or lower, holding the shift lever toward “+” sets the shift range
to 6.
●To prevent excessive engine speed, a function was adopted that automatically selects a
higher shift range before the engine speed becomes too high.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
the engine brake will not operate in the S mo de, even when downshifting to 5 or 4.
(  P. 2 3 4 )
■Downshifting restrictions warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever is operated. (A buzzer will sound twice.)
■If the S indicator does not come on ev en after shifting the shift lever to S
This may indicate a malfunct ion in the hybrid transmission system. Have the vehicle
inspected by your Lexus dealer immediately.
(In this situation, the transmission will operat e in the same manner as when the shift lever
is in D.)
■If the shift lever cannot be shifted from P
 P. 5 2 0
■AI-SHIFT
AI-SHIFT automatically select s the suitable gear according to driver performance and
driving conditions.
AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever to S
cancels the function.)
WA R N I N G
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause th e vehicle to spin or skid, resulting in an
accident.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid batter y (traction battery) will not be charged even
when the engine is running. Therefore, if the ve hicle is left with the shift lever in N for a
long period of time, the hybrid battery (tr action battery) will discharge, and this may
result in the vehicle not being able to start.

PCS (Pre-Collision System)
◆Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.
◆Pre-collision brake assist
When the system determines that the po
ssibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.
: If equipped
The pre-collision system uses a radar sensor and camera sensor to detect
vehicles and pedestrians
*1 in front of your vehicle. When the system deter-
mines that the possibility of a frontal collision with a vehicle or pedestrian is
high, a warning operates to urge the driver to take evasive action and the
potential brake pressure is increased to help the driver avoid the collision. If
the system determines that th e possibility of a frontal collision with a vehicle or
pedestrian is extremely high, the brakes are automatically applied
*2 to help
avoid the collision or help reduce the impact to the vehicle occupants and the
vehicle in the collision.
The pre-collision system can be disabl ed/enabled and the warning timing can
be changed. ( P. 2 0 4 )
*1: Depending on the region in which the vehicle was sold, the pedestrian detection
function may not be available. Contact your Lexus dealer for details.
*2: Depending on the region in which the vehicle was sold, the pre-collision brakingfunction (automatic braking function) may not be available. Contact your Lexus
dealer for details.

LDA (Lane Departure Alert with steering control)
When driving on highways and freeways with white or yellow lines, this function
alerts the driver when the vehicle might depart from its lane and provides assis-
tance by operating the steering wheel to keep the vehicle in its lane.
The LDA system recognizes visible
white or yellow lines with the camera
sensor on the upper portion of the front
windshield.
◆Lane departure alert function
When the system determines that
the vehicle might depart from its
lane, a warning is displayed on the
multi-information display, and either
the warning buzzer sounds or the
steering wheel vibrates to alert the
driver.
When the warning buzzer sounds or
the steering wheel vibrates, check
the surrounding road situation and
carefully operate the steering wheel
to move the vehicle back to the cen-
ter within the white (yellow) lines.

the vehicle might depart from its
lane, the system provides assistance
as necessary by operating the steer-
ing wheel in small amounts for a
short period of time to keep the
vehicle in its lane.
If the system detects that the steering
wheel has not been operated for a
fixed amount of time or the steering
wheel is not being firmly gripped, a
warning is displayed on the multi-
information display and the function
is temporarily canceled.
◆Ve h i c l e s w a y w a r n i n g
When the vehicle is swaying or
appears as if it may depart from its
lane multiple times, the warning
buzzer sounds and a message is dis-
played on the multi-information dis-
play to alert the driver.
