■Downshifting restrictions warning buzzer (in the “S” mode)
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 is operated. (The warning buzzer will sound twice.)
■When driving with the cruise control system (or dynamic radar cruise control sys-
tem)
The engine brake will not operate in the “S” mode, even when downshifting to “5” or
“4”. (→P. 1 6 9 )
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the “POWER” switch is turned to
ACCESSORY or ON mode after driving in snow mode.
■If the shift lever cannot be shifted from “P”
→P. 5 2 9
■If the indicator does not come on even after shifting the shift lever to “S”
This may indicate a malfunction in the transmission. Have the vehicle inspected by
your Lexus dealer immediately.
(In this situation, the vehicle will operate as if the shift lever is in “D”.)
■When in heavy traffic
To avoid running the hybrid battery (traction battery) down, leave the shift lever in
“D” or “S”.
