The installation of a mobile two-way radio system in your vehicle could affect elec-
tronic systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
●Dynamic radar cruise control system
●Cruise control system
●Anti-lock brake system
●SRS airbag system
●Seat belt pretensioner system
Be sure to check with your Lexus dealer for precautionary measures or special
instructions regarding installation of a mobile two-way radio system.
Hybrid vehicles: High voltage parts and cables on the hybrid vehicles emit approxi-
mately the same amount of electromagnetic waves as the conventional gasoline
powered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Hybrid vehicles: Unwanted noise may occur in the reception of the mobile two-way
radio.

4-2. Driving procedures
■S mode
●When the shift range is S4 or lower, holding the shift lever toward “+” sets the shift
range to S6.
●To prevent excessive engine speed, a function was adopted that automatically
selects a higher shift range before the engine speed becomes too high.
●To protect the automatic transmission, a function is adopted that automatically
selects a higher shift range when the fluid temperature is high.
■When driving with cruise control activated
Even when performing the following actions with the intent of enabling engine brak-
ing, the engine brake will not operate in the S mode, even when downshifting to 5 or
4. ( P. 2 5 4 )
■Downshifting restrictions warning buzzer
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. (A buzzer will sound twice.)
■If the S indicator does not come on even after shifting the shift lever to S
This may indicate a malfunction in the auto matic transmission system. Have the vehi-
cle inspected by your Lexus dealer immediately.
(In this situation, the transmission will operate in the same manner as when the shift
lever is in D.)
■If the shift lever cannot be shifted from P
 P. 6 76
■AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver performance
and driving conditions.
AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever
