■Downshifting restrictions warning buzzer
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever or paddle shift switch (if equipped) is operated. (A buzzer will
sound twice.)
■When driving with cruise control, dynamic radar cruise control or dynamic radar
cruise control with full speed range activated
Even when performing the following actions with the intent of enabling engine brak-
ing, engine braking will not activate because cruise control, dynamic radar cruise
control or dynamic radar cruise control with full speed range will not be canceled.
●While driving in D or S mode, downshifting to 7, 6, 5 or 4. ( P. 289, 293, 307)
●When switching the driving mode to sport mode while driving in D position.
( P. 334)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if th e power switch is turned off after driving
in snow mode.
■Shift lock system
The shift lock system is a system to prevent accidental operation of the shift lever in
starting.
The shift lever can be shifted from P only when the power switch is in ON mode and
the brake pedal is being depressed.
■If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may be a
problem with the shift lock system. Have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional imme-
diately.
The following steps may be used as an emergency measure to ensure that the shift
lever can be shifted.
Releasing the shift lock:
Turn the power switch to ON mode ( P. 248) and check that the parking brake is
set.
Turn the power switch off.
Depress the brake pedal.

CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehi-
cle skidding to the side or spinning.
■To prevent an accident when releasing 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 pedal 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, possibly leading to an accident resulting in death or
serious injury.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid battery (traction battery) will not be charged
even when the engine is running. Therefore, if the vehicle is left with the shift lever
in N for a long period of time, the hybrid battery (traction battery) will discharge,
and this may result in the vehicle not being able to start.
