CAUTION
■If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning light not
come on when you turn to “IG-ON” mode, this could mean that these systems are
not available to help protect you in an accid ent, which could result in death or seri-
ous injury. Have the vehicle inspected by your Lexus dealer immediately if this
occurs.
■ Warning lights
Warning lights inform the driver of malfunctions in the indicated
vehicle’s systems. ( P. 4 3 8 )
*: These lights turn on when the power switch is turned to “IG-ON” mode
to indicate that a system check is being performed. They will turn off
after the hybrid system is on, or af ter a few seconds. There may be a mal-
function in a system if the lights do not come on, or turn off. Have the
vehicle inspected by your Lexus dealer.

When driving
Multi-information display
The multi-information display presents the driver with a variety of driving-
related data, including the status of the hybrid system.
●Energy monitor ( P. 6 )
Displays the status of the hybrid
system.
●Trip information ( P. 120)
Displays driving range, fuel con-
sumption and other cruising
related information.
●Intuitive parking assist dis-
play (if equipped) ( P. 143)
Automatically displayed when
using intuitive parking assist.
●Dynamic radar cruise con-
trol display (if equipped) 
( P. 1 3 2 )
Automatically displayed when
using dynamic radar cruise con-
trol.
●Warning messages 
( P. 444)
Automatically displayed when a
malfunction occurs in one of the
vehicle’s systems.

When driving
Cruising in vehicle-to-vehicle distance control mode This mode employs a radar sensor to detect the presence of vehicles
within 400 ft. (120 m) ahead and to judge the distance between your
vehicle and those vehicles.
Note that vehicle-to-vehicle distance will close when trave ling on long down-
hill slopes.
Example of constant speed cruising (when there are no vehicles
ahead): When vehicle speed is set at 62 mph (100 km/h)
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehi-
cle distance can also be set by operating the vehicle-to-vehicle distance
switch.
Example of deceleration cruising (wh en the vehicle ahead is driving
slower than the set speed): When fixed speed cruising is set at 62 mph
(100 km/h) and the vehicle ahead is driving at 50 mph (80 km/h)
When a vehicle is detected running ahead of you, in the same lane, the sys-
tem automatically decelerates your vehicle. When a greater reduction in
vehicle speed is necessary, the system applies the brakes. A warning tone
warns you when the system cannot decelerate sufficiently to prevent your
vehicle from closing on the vehicle ahead.

2-4. Using other driving systems
Example of follow-up cruising (when following a vehicle driving slower
than the set speed): When the speed is set at 62 mph (100 km/h) and
the vehicle ahead is driv ing at 50 mph (80 km/h)
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration (when ther e are no longer vehicles driving
slower than the set speed in the lane ahead): When the speed is set at
62 mph (100 km/h) and the vehicle ahead driving at 50 mph (80 km/
h) is out of the lane
When the vehicle ahead of you executes a lane change, the system slowly
accelerates until the set vehicle speed is reached. The system then returns to
fixed speed cruising.
■Dynamic radar cruise control warn ing lights, messages and buzzers
Warning lights, messages and buzzers are us ed to indicate a system malfunction or
to alert you to the need for caution while driving. ( P. 4 4 6 )
■The dynamic radar cruise can be set when
●The shift lever is in “D” or the “4”, “5” or “6” range of “S”.
●Vehicle speed is between approximately 27 mph (43 km/h) and 87 mph (139
km/h).
■Accelerating
The vehicle can be accelerated normally. After acceleration, the set speed
resumes.

■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice or plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.

When driving
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 mult i-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, an d one in each corner of the bumper,
to detect obstacles in those areas. 
The dual sensors detect obstacles ahea d of the vehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. [25 cm] of the vehicl e), 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.

Sensor detection display, obstacle distance and beepsWhen the intuitive parking assist is activated, the approximate distance to
the obstacle is displayed. Also, if an obstacle with which a collision is pos-
sible is detected, a warning beep will sound.
■ Dual sensor
• If the shift lever is in “R”, only th e corner sensors will detect obstacles.
