*1: Shifting to the D position allows the sys-tem to select a gear suitable for the
driving conditions. Setting the shift lever
to the D position is recommended for
normal driving.
*2: Selecting gears using M mode fixes the gear step, controls engine braking
force, and prevents unnecessary
upshifting.
■To protect the automatic transmission
If the automatic transmission fluid tempera-
ture is high, “Transmission Fluid Temp High
See Owner’s Manual” will be displayed on
the multi-information display and the vehi-
cle will go into transmission protection
mode automatically. Have the vehicle
inspected by your Lexus dealer.
■When driving with 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 occur
NOTICE
■To prevent battery discharge
Do not stop the engine when the shift
lever is in a position other than P. If the
engine is stopped in another shift lever
position, the engine switch will not be
turned off but instead be turned to
ACCESSORY mode. If the vehicle is left
in ACCESSORY mode, battery dis-
charge may occur.

emergency measure to ensure that the shift
lever can be shifted.
Releasing the shift lock:
1Turn the engine switch to IGNITION
ON mode and check that the parking
brake is set. ( P.179, 185)
2 Turn the engine switch to off.
3 Depress the brake pedal.
4 Pry the cover up with a flathead screw-
driver or equivalent tool.
To prevent damage to the cover, cover the
tip of the screwd river with a rag.
5 Press the shift lock override button.
The shift lever can be shifted while the but-
ton is pressed.
 P.274
To drive using temporary shift range
selection, operate the “-” or “+” paddle
shift switch.
When the “-” paddle shift switch is
operated, the shift range will be down-
shifted to a range that enables engine
braking force that is suitable to driving
conditions. When the “+” paddle shift
switch is operated, the shift range will
be one gear higher than the gear in use
during normal D position driving.
Changing the shift range allows
restriction of the highest gear, prevent-
ing unnecessary upshifting and
enabling the level of engine braking
force to be selected.
1 Upshifting
2 Downshifting
The selected shift rang e, from D1 to D8,
will be displayed on the meters.
WARNING
■To prevent an accident when releas-
ing the shift lock
Before pressing the shift lock override
button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pe dal is accidentally
depressed instead of the brake pedal
when the shift lock override button is
pressed and the shift lever is shifted out
of P, the vehicle may suddenly start, pos-
sibly leading to an accident resulting in
death or serious injury.

Driving
The system can detect the following:
Vehicles
 Bicyclists
 Pedestrians
■Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage will be displayed on the
multi-information display to urge the driver to take evasive action.
■Pre-collision 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.
■Pre-collision braking
If the system determines that the possi-
bility of a frontal collision is extremely
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
■Suspension control (if equipped)
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension Sys-
tem ( P.278) will control the damp-
ing force of the shock absorbers to
help maintain an appropriate vehicle
posture.
PCS (Pre-Collision System)
The pre-collision system uses a
radar sensor and front camera to
detect objects ( P.211) in front of
the vehicle. When the system
determines that the possibility of a
frontal collision with an object is
high, a warning operates to urge
the driver to take evasive action
and the potential brake pressure is
increased to help the driver avoid
the collision. If the system deter-
mines that the possibility of a frontal
collision with an object is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. ( P.213)
