■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●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.
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
●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 the low range in the “S” position.
• 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 drums are replaced.
Have your Lexus dealer perform the bedding-down.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (P. 5 9 0 )
■When starting on an incline
The hill-start assist control may operate. (P. 2 1 4 )

CAUTION
■When driving the vehicle
●Moving the shift lever to "N" while the vehicle is moving will disengage the hybrid
system. Engine braking is not available with the hybrid system disengaged.
●During normal driving, do not turn off the hybrid system. Turning the hybrid sys-
tem off while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to steer
and brake, so you should pull over and stop the vehicle as soon as it is safe to do
so.
However, in the event of an emergency, such as if it becomes impossible to stop
the vehicle in the normal way: P. 5 3 4
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill. 
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (P. 1 5 6 )
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Be careful when driving on slippery surfaces, as the vehicle may spin or skid when
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents that may
result in death or serious injury.
●Always check that all passengers’ arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.
●The driver should pay attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). Because there is no engine sounds, the
pedestrians may misjudge the vehicle’s movement.

Intuitive parking assist
: If equipped
Intuitive parking assist uses sensors in the front and rear of the vehicle to
detect the distance between the vehicle and any obstacles, and informs the
driver of this distance using the multi-information display, the touch screen,
and warning beeps.
The system may be used at speeds less than about 6 mph (10 km/h).
■Sensor types
Dual sensors
There are 4 sensors installed in the front bumper, two in the center section
to detect obstacles directly ahead, and one in each corner of the bumper,
to detect obstacles in those areas.
The dual sensors detect obstacles ahead of the vehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. [25 cm] of the vehicle), according to the distance between
the obstacle and the vehicle, and the steering wheel position. The screen
display and beeps will change accordingly.
Rear corner sensors
These sensors detect obstacles around the rear corners of the vehicle.
Back sensors
These sensors detect obstacles behind the vehicle.
