■Automatic deactivation of shift range selection in the D position (vehicles with paddle
shift switches)
Shift range selection in the D position will be deactivated in the following situations:
●The “+” paddle shift switch is held down for a period of time
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for more than a certain period of time
●When the shift lever is shifted to a position other than D
■To protect the automatic transmission
If the automatic transmission fluid temperat ure is high, “Transmission Fluid Temp High See Owner’s Manual” will be displayed on the multi-information display and the vehicle
will go into transmission protection mode automatically. Have the vehicle inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped profes-sional.
■Downshifting restri ction warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes be restricted. In some circumstances, down shifting may not be possible even when the
shift lever or paddle shift switch (if equipp ed) is operated. (A buzzer will sound twice.)
■When driving with cruise control or dynamic radar cruise control with full-speed range activated
Even when performing the following actions with the intent of enabling engine braking, engine braking will not activate because crui se control or dynamic radar cruise control with full-speed range will not be canceled.
●Vehicles with paddle shift switches (8-sp eed models): While driving in D position, downshifting to 7, 6, 5 or 4. ( P. 329, 341)
●Vehicles with paddle shift switches (6-speed models): While driving in D position,
downshifting to 5 or 4. ( P. 329, 341)
●When switching the driving mode to sport mode while driving in D position. (P. 417)
■Restraining sudden start (Drive-Start Control)
When the following unusual operation is performed, the engine output may be restrained.
●When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D includes
M) with the accelerator pedal depressed, a warning message appears on the multi- information display. If a warning message is shown on the multi-information display, read the message and follow the instructions.
●When the accelerator pedal is depressed too while the vehicle is in reverse.
■Shift lock system
The shift lock system is a system to prevent accidental operation of the shift lever in start- ing.The shift lever can be shifte d from P only when the engine switch is in IGNITION ON
mode and the brake pedal is being depressed.

Turns the brake hold system on
The brake hold standby indicator
(green) comes on. While the system is holding the brake, the brake hold oper-ated indicator (yellow) comes on.
■Brake hold system operating conditions
The brake hold system cannot be turn ed on in the following conditions:
●The driver’s door is not closed.
●The driver is not wearing the seat belt.
If any of the conditions above are detected when the brake hold system is enabled, the
system will turn off and the brake hold standby indicator light will go off. In addition, if any of the conditions are detected while the sy stem is holding the brake, a warning buzzer will sound and a message will be shown on th e multi-information display. The parking
brake will then be set automatically.
■Brake hold function
●If the brake pedal is left released for a pe riod of about 3 minutes after the system has
started holding the brake, th e parking brake will be set automatically. In this case, a warning buzzer sounds and a message is shown on the multi-information display.
●To turn the system off while the system is holding the brake, firmly depress the brake
pedal and press the button again.
●The brake hold function may not hold the vehicle when the vehicle is on a steep incline. In this situation, it may be necessary for the driver to apply the brakes. A warning
buzzer will sound and the multi-information disp lay will inform the driver of this situa- tion. If a warning message is shown on the multi-information display, read the message and follow the instructions.
Brake Hold
The brake hold system keeps the brake a pplied when the shift lever is in D, M
or N with the system on and the brake pedal has been depressed to stop the
vehicle. The system releases the brake when the accelerator pedal is
depressed with the shift lever in D or M to allow smooth start off.

RX350/RX200t_EE_OM48F32E
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle
following distance, and operates to maintain 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 button.
Example of deceleration cruising and follow-up 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 reductio n in vehicle speed is necessary, the system applies the brakes (the stop lights will come on at this time). The system will respond to
changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver. Approach wa rning warns you when the system cannot decelerate sufficiently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your ve hicle will also stop (vehicle is stopped by system control). After the vehicle ahead starts off, pushing the cruise control lever upor depressing the accelerator peda l will resume follow-up cruising.
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.

Pressing the button changes the vehi-
cle-to-vehicle distance as follows:
Long
Medium
Short
The vehicle-to-vehicle distance is set automatically to long mode when theengine switch is turned to IGNITION
ON mode.
If a vehicle is running ahead of you, the preceding vehicle mark will also be displayed.
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 80 km/h (50 mph). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed. When the vehicle is
stopped by system control, the vehicle- to-vehicle distance will be about 3 m
(10 ft.) to 5 m (16 ft.) regardless of the vehicle-to-vehicle distance setting.
After the vehicle ahead of you starts off,
push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.

switch will enable the system but no t stop the engine. From the next time
the vehicle is stopped (after the Stop & Start system has been enabled), the
engine will be stopped.
If the engine is stopped by the Stop & Start system when the vehicle is on an
incline, brake force is temporarily maintained to prevent rolling backwards until
the engine is restarted and drive force is generated. When drive force is gener-
ated, the maintained brake force is automatically canceled.
●This function operates on flat surfaces as well as steep inclines.
●Sound may be generated from the brak es, but this is not a malfunction.
●Brake pedal response may change and vibration may occur, but these are not
malfunctions.
