CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag warning lights not
come on when you start the engine, this could mean that these systems are not
available to help protect you in an accident, which could result in death or serious
injury. Have the vehicle inspected by your Lexus dealer immediately if this occurs.
■Warning lights
Warning lights inform the driver of malfunctions or suspected prob-
lem in any of the vehicle’s systems. ( oP. 4 3 9 )
*: These lights turn on when the “ENGINE START STOP” switch is turned
to IGNITION ON mode to indicate that a system check is being per-
formed. They will turn off after the engine is started, or after a few sec-
onds. There may be a malfunction in a system if a light does not come on,
or if the lights do not turn off. Have the vehicle inspected by your Lexus
dealer.

sumption and other cruising
related information.

play (if equipped)
(oP. 1 6 5 )
Automatically displayed when
using intuitive parking assist.
●Dynamic radar cruise con-
trol display (if equipped)
(oP. 1 5 5 )

When driving
ES350_UExample of constant speed cruising (when there are no vehicles
ahead): When set to 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 (when 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.
Example of follow-up cruising (when following a vehicle driving slower
than the set speed): When the speed is set to 62 mph (100 km/h) and
the vehicle ahead is driving 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.

ES350_UExample of acceleration (when there are no longer vehicles driving
slower than the set speed in the lane ahead): When the speed is set to
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.
■Fine adjustment of the set speed
Adjustment of the set speed by the following speed can be made by lightly pressing
the lever up or down and releasing it.
In the constant speed control mode: Approximately 1.0 mph (1.6 km/h)
In the vehicle-to-vehicle distance control mode: USA: Approximately 5 mph (8 km/h)
Canada: Approximately 3 mph (5 km/h)
■Dynamic radar cruise control warning lights, messages and buzzers
Warning lights, messages and buzzers are used to indicate a system malfunction or
to alert you to the need for caution while driving. ( oP. 4 4 9 )
■Dynamic radar cruise control can be set when
●The shift lever is in D or the 4, 5 or 6 range of S.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Accelerating
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may
decrease below the set speed in order to maintain the distance to the vehicle
ahead.
■Automatically canceling vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations.
●Vehicle speed falls below 25 mph (40 km/h)
●VSC is activated
●The sensor cannot operate correctly because it is covered in some way.*

Back sensor operation display and distance to an obstacle
The system operates when the vehicle approaches within approxi-
mately 4.9 ft. (150 cm) of an obstacle.
Approximately 4.9 ft. (150 cm)
to 2.0 ft. (60 cm) from the
obstacle
Approximately 2.0 ft. (60 cm) to
1.5 ft. (45 cm) from the obstacle
Approximately 1.5 ft. (45 cm) to
1.2 ft. (35 cm) from the obstacle
Flashing: Within 1.2 ft. (35 cm)
of the obstacle
■ Buzzer operation and di stance to the obstacle
A buzzer sounds when the corner sensors and back sensor are oper-
ating.
● The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obsta-
cle, the buzzer sounds continuously.
•Corner sensors: Approximately 0.8 ft. (25 cm)
• Back sensors: Approximately 1.2 ft. (35 cm)
● When two or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle.
● If multiple obstacles are detected within 0.8 ft. (25 cm) in front and
behind the vehicle at the same time, the warning buzzer will change
in the following manner:
• If a continuous beep is sounding, and a new obstacle is detected
near a different area of the vehicle, the warning buzzer will sound
6 beeps then one continuous beep.
• If a continuous beep is sounding, and a new obstacle is detected within 0.8 ft. (25 cm) of a different area of the vehicle, the warn-
ing buzzer will sound 2 beeps then one continuous beep.

■The pre-collision system is operational when
●Pre-collision seat belt (linked to the radar sensor)
• Vehicle speed is above 3 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or oncomingvehicle exceeds 18 mph (30 km/h).
• The front occupants are wearing a seat belt.
●Pre-collision seat belts (linked to brake operation)
• Vehicle speed is above 9 mph (15 km/h).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
●Pre-collision brake assist
• Vehicle speed is above 18 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle is greater than about 18 mph (30 km/h).
• The brake pedal is depressed.
■Conditions that may trigger the system even if there is no danger of collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When there is a metal plate in the road in front of the vehicle on a downhill slope
●When there is a metal object such as a sign board in front of the vehicle on an
uphill slope
●When driving on an uneven road surface
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front
●When your vehicle is skidding with the VSC system off
When the system is activated in the situations described above there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. ( oP. 439, 449)
