To change the set speed, operate the lever until the desired set speed is dis-
played.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily move
the lever in the desired direction.
Large adjustment: Hold the lever in the
desired direction.
In the vehicle-to-vehicle distance control mode, the set speed will be increased
or decreased as follows:
• When the set speed is shown in “km/h”
Fine adjustment: By approximately 5 km/h (3.1 mph) each time the lever is operated
Large adjustment: By approximately 5 km/h (3.1 mph) for each 0.75 seconds the
lever is held
• When the set speed is shown in “MPH”
Fine adjustment: By approximately 5 mph (8 km/h) each time the lever is operated
Large adjustment: By approximately 5 mph (8 km/h) for each 0.75 seconds the lever is held
In the constant speed control mode ( P. 263), the set speed will be increased
or decreased as follows:
Fine adjustment: By approximately 1.6 km/h (1 mph) each time the lever is operated
Large adjustment: The set speed can be incr eased or decreased continually until the lever is released.

When constant speed control mode is selected, your vehicle will maintain a set
speed without controlling the vehicle-to-vehicle distance. Select this mode only
when vehicle-to-vehicle distance control mode does not function correctly due
to dirt, etc.
Press the “ON/OFF” button to acti-
vate the cruise control.
Press the button again to deactivate the cruise control.
Switch to constant speed control
mode.
(Push the lever forward and hold for
approximately 1 second.)
Cruise control indicator will come on.
When in constant speed control mode, to return to vehicle-to-vehicle distance con- trol mode, push the lever forward again and hold for approximately 1 second.
After the desired speed has been set, it is not possible to return to vehicle-to-vehicle distance control mode.
If the power switch is turned off and then turned to ON mode again, the vehicle will
automatically return to vehicle-to-vehicle distance control mode.
Adjusting the speed setting: P. 260
Canceling and resuming the speed setting: P. 262
■Dynamic radar cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been selected.
●Range 4 or higher of D has been selected by using the paddle shift.
●Vehicle speed is above approximately 50 km/h (30 mph).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehi-cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle.

■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle dis- tance control mode operates properly. (Some ob structions, such as snow, ice and plastic
objects, cannot be detected by the obstruction sensor.) Dynamic radar cruise control is canceled if an obstruction is detected.
■Operation guide display
When the dynamic radar cruise control switch is operated, a guidance display is shown
on the meters for a few seconds as to how to operate the dynamic radar cruise control switch or distance switch. ( P. 126)
■Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or to inform the driver of the need for caution while driving. ( P. 548)

WARNING
■When using the Lexus parking assist monitor system
The parking assist monitor is a supplemental device intended to assist the driver when backing up. When backing up, be sure to check visually behind and all around the vehi-
cle before proceeding.
Observe the following precautions to avoid an accident that could result in death or serious injuries.
●Never depend on the parking assist monitor entirely when backing up. The imageand the position of the guide lines displayed on the screen may differ from the actualstate.
Use caution, just as you would when backing up any vehicle.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●If you seem likely to hit nearby vehicles , obstacles, people or mount the shoulder,
depress the brake pedal to stop the vehicle.
●The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic condi-
tions, road surface conditions, vehicle condition, etc. when parking. It is necessary to be fully aware of this before using the parking assist system.
●When parking, be sure to check that th e parking space will accommodate your vehi-
cle before maneuvering into it.
●Do not use the parking assist monitor in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires • When the trunk is not closed completely• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. Theimage could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check direct visually and with the mirrors all around the vehicle before proceeding.
●If the tire sizes are changed, the position of the guide lines displayed on the screen
may change.
●The camera uses a special lens. The distances between objects and pedestrians that appear in the image displayed on the screen will differ from the actual distances.
( P. 294)
●Estimated course line display mode: If the steering wheel is straight and the vehicle width guide lines and the estimated course lin es are not in alignment, have the vehicle
inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.

Vehicles without Adaptive Variable Suspension System
Normal mode
Provides an optimal balance of fuel ec onomy, quietness, and dynamic perfor-
mance. Suitable for city driving.
Press the switch to change the driving mode to normal mode when Eco drive mode or sport mode is selected.
Eco drive mode
Helps the driver accelerate in an eco-friendly manner and improve fuel econ-
omy through moderate throttle characteristics and by controlling the opera-
tion of the air conditioning system (heating/cooling).
When not in Eco drive mode, if the driving mode select switch is turned to the left, the Eco drive mode indicator will come on.
Sport mode
Controls the hybrid system to provide quick, powerful acceleration. This
mode also changes the steering feel, making it suitable for when agile driving
response is desired, such as when driving on roads with many curves.
When not in sport mode, if the driving mode select switch is turned to the right, the
“SPORT” indicator will comes on.

4-6. Driving tips
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accelerator
pedal depression amount can be generate d more smoothly than it is in normal
conditions. In addition, the operation of the air conditioning system (heating/
cooling) will be minimized, improving the fuel economy. ( P. 301)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the needle of Hybrid System
Indicator within Eco area. ( P. 119)
◆Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in heavy traf-
fic etc. Shift the shift lever to P when parking. When using the N, there is no
positive effect on fuel consumption. In the N, the gasoline engine operates but
electricity cannot be generated. Also, when using the air conditioning system,
etc., the hybrid battery (traction battery) power is consumed.
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and deceleration.
Gradual acceleration and deceleration will make more effective use of the
electric motor (traction motor) without having to use gasoline engine
power.
●Avoid repeated acceleration. Repeated acceleration consumes hybrid bat-
tery (traction battery) power, resulting in poor fuel consumption. Battery
power can be restored by driving with the accelerator pedal slightly
released.
