●The AI-SHIFT automatically selects the suitable gear according to driver performance
and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift
lever to the M position cancels the function.)
●8-speed models: G AI-SHIFT automatically selects 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 switch or shifting the shift lever to the M
position cancels this function.)

■When driving on slippery road surfaces
Be careful of downshifting and sudden acceler ation, as this could result in the vehicle
skidding to the side or spinning.
■Gear Shift Indicator display
For safety, the driver should not look only at the display. Refer to the display when it is
safe to do so while considering actual traffic and road conditions.
Failure to do so may lead to an accident.

Brake Hold (GS350/GS200t)
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.
●“EPB Activation Stopped Incompletely” or “Electronic Parking Brake Malfunction Visit
Your Dealer” is displayed on the multi-information display.
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 period 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 di splay will inform the driver of this situa-
tion. ( →P. 5 1 8 )
The brake hold system keeps the brake applied 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.

PCS (Pre-Crash Safety system)∗
◆Pre-crash warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.
◆Pre-crash brake assist
When the system determines that the possibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.
∗: If equipped
The pre-crash safety system uses a radar sensor and camera sensor to detect
vehicles and pedestrians
*1 in front of your vehicle. When the system deter-
mines that the possibility of a frontal collision with a vehicle or pedestrian is
high, a warning operates to urge the dr iver to take evasive action and the
potential brake pressure is increased to help the driver avoid the collision. If
the system determines that the possibility of a frontal collision with a vehicle or
pedestrian is extremely high, the brakes are automatically applied
*2 to help
avoid the collision or help reduce the impact of the collision.
The pre-crash safety system can be disabled/enabled and the warning timing
can be changed. ( →P. 2 9 6 )
*1: Depending on the region in which the vehicle was sold, the pedestrian detection
function may not be available. Contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional for details.
*2: Depending on the region in which the vehicle was sold, the pre-crash braking func-tion (automatic braking function) may not be available. Contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional for
details.
