RC350_RC300_RC200t_RC F_U (OM24671U)
■Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
●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 temperature is high, “Transmission Fluid High Temper-
ature” will be displayed on the multi-information display and the vehicle will go into trans-
mission protection mode automatically. Have the vehicle inspected by your Lexus dealer.
■Downshifting restriction warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is turned off after driving in
snow mode.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or dynamic radar cruise control
will not be canceled.
●8-speed models: While driving in the D posi tion, downshifting to 7, 6, 5 or 4.
(  P. 235, 239)
●6-speed models: While driving in the D position, downshifting to 5 or 4.
( P. 235, 239)
●When switching the driving mode to sp ort mode while driving in D position.
(  P. 2 8 3 )
■If the shift lever cannot be shifted from P
P. 5 9 9
■AI-SHIFT
●The AI-SHIFT automatically selects the suitab le gear according to driver performance
and driving conditions.
The AI-SHIFT automatically operates when the sh ift lever is in D. (Shifting the shift lever
to the M position cancels the function.)
●8-speed models: G AI-SHIFT automatically se lects a suitable gear for sporty driving
according to driver’s input and driving co nditions. G AI-SHIFT operates automatically
when the shift lever is in D and sport mode is selected for the driving mode. (Selecting
normal mode with the driving mode select sw itch or shifting the shift lever to the M
position cancels this function.)

■When driving on slippery road surfaces
Be careful of downshifting and sudden accele ration, as this could result in the vehicle
skidding to the side or spinning.

Pulling the lever toward you cancels
the speed control.
The speed setting is also canceled when
the brake pedal is depressed.
Pushing the lever up resumes the
speed control and returns vehicle
speed to the set speed.
Resuming is available when the vehicle
speed is more than approximately 25
mph (40 km/h).
When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the driver.
An example of this would be if another
driver cuts in front of you while you are
following a vehicle. Depress the brake
pedal to ensure an appropriate vehicle-
to-vehicle distance.
■Warnings may not occur when
In the following instances, there is a po ssibility that the warnings will not occur:
●When the speed of the preceding vehicle matches or exceeds your vehicle
speed
●When the preceding vehicle is traveling at an extremely slow speed
●Immediately after the cruise control speed was set
●When depressing the accelerator pedal
