closed if the doors are locked. If the doors are locked and the fuel filler door cannot be
closed, unlock the doors and th en close the fuel filler door.
■Fuel filler door lock condition
The fuel filler door may not be locked even wh en the vehicle’s doors are locked in the fol-
lowing situations:
●When operating the door lock button inside the vehicle
●When the automatic door locking system is operated ( P. 6 5 5 )

To change the set speed, operate the lever until the desired set speed is obtained. 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.
The set speed will be increase d or decreased as follows:
Fine adjustment: By approximately 1 mph (1.6 km/h) each time the lever is operated.
Large adjustment: The set speed can be incr eased or decreased continually until the
lever is released.
Pulling the lever toward you cancels
the constant speed control.
The speed setting is also canceled when
the brake pedal is depressed.
Pushing the lever up resumes the
constant speed control.
However, resuming is available when
the vehicle speed is more than approxi-
mately 25 mph (40 km/h).

■Cruise control can be set when
●The shift lever is in D.
●Range 4 or higher of D has been selected by using the paddle shift.
●Vehicle speed is above approximately 25 mph (40 km/h).
■Accelerating after setting the vehicle speed
●The vehicle can be accelerated by operating accelerator pedal. After accelerating, the
set speed resumes.
●Even without canceling the cruise control, the set speed can be increased by first accel-
erating the vehicle to the desired speed and then pushing the lever down to set the new
speed.
■Automatic cruise control cancelation
Cruise control is automatically canceled in any of the following situations.
●Actual vehicle speed falls more than approximately 10 mph (16 km/h) below the set
speed.
●Actual vehicle speed is below approximately 25 mph (40 km/h).
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is turned off by pressing the VSC OFF switch.
■If the warning message for the cruise contro l is shown on the multi-information display
Press the “ON/OFF” button once to deactivate the system, and then press the button
again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels immediately after
being activated, there may be a malfunction in the cruise control system. Have the vehi-
cle inspected by your Lexus dealer.

Switch the cruise control off using th e “ON/OFF” button when not in use.
■Situations unsuitable for cruise control
Do not use cruise control in any of the following situations.
Doing so may result in loss of control and could cause an accident resulting in death or
serious injury.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as thos e covered with rain, ice or snow
●On steep hills
Vehicle speed may exceed the set speed when driving down a steep hill.

Without accelerator pedal operation by the driver, in vehicle-to-vehicle distance
control mode, the vehicle automatically accelerates and decelerates in accor-
dance to the changes in speed of the preceding vehicle. In constant speed con-
trol mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control on freeways and highways.
●Vehicle-to-vehicle distance control mode ( P. 2 4 0 )

RC350_RC300_RC200t_RC F_U (OM24671U)
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle
following distance, and operates to main tain a suitable following distance from
the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating the vehicle-to-vehicle distance control.
Example of deceleration cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the system
applies the brakes (the stop lights will come on at this time). A warning tone warns you
when the system cannot decelera te sufficiently to prevent your vehicle from closing in
on the vehicle ahead.
Example of follow-up cruising
When following a preceding vehicle driving slower than the set speed
The system continues follow-up cruising wh ile adjusting for changes in the speed of
the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.
