23Installation of a mobile two-way radio system The installation of a mobile two-way radio system in your vehicle could affect elec-
tronic systems such as: ●
Hybrid system●
Multiport fuel injection system/sequential multiport fuel injection system●
Cruise control system●
Dynamic radar 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.
High voltage parts and cables on the hybr id vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.
Vehicle data recordings Your Lexus is equipped with several soph isticated computers that will record cer-
tain data, such as:
•Engine speed
• Motor speed
• Accelerator status
•Brake status
•Vehicle speed
•Shift position
• Hybrid battery (traction battery) status
The recorded data varies according to the vehicle grade level and options with
which it is equipped. Furthermore, these computers do not record conversations,
sounds or pictures.

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.)
