When driving ■
AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver performance
and driving conditions.
AI-SHIFT automatically operates when the sh ift lever is in the D position. (Shifting
the shift lever to the S posi tion cancels the function.)■
When driving with cruise control or radar cruise control activated
Even when performing the following acti ons with the intent of enabling engine
braking, engine braking will not activate because cruise control or radar cruise
control will not be canceled. ●
While driving in D or S mode, downshifting to 5 or 4. (  P. 232, 236)●
When switching the driving mode to sport mode while driving in D position.
(  P. 1 8 9 )■
If the shift lever cannot be shifted from P
 P. 7 7 9■
If S does not come on even after shifting the shift lever to S
This may indicate a malfunction in the hybr id transmission system. Have the vehicle
inspected by your Lexus dealer immediately.
(In this situation, the hybrid transmission will operate in the same as manner as when
the shift lever is in D.)■
Downshift restriction warning buzzer (S mode)
To help ensure safety and driving perfor mance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever is operated. (The buzzer will sound twice.)

1922-1. Driving procedures
CAUTION■
When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in
an accident.
NOTICE■
Hybrid battery (traction battery) charge precaution
If the shift lever is in N, the hybrid battery (traction battery) wi ll 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.

achieved.●
Charge area indicates regeneration* st atus. Regenerated energy will be used
to charge the hybrid battery (traction battery).
*: When used in this manual, “regeneration” refers to the conversion of energy cre-
ated by the movement of the ve hicle into electrical energy.■
ECO lamp and SPORT lamp ●
