When driving
■ Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air
conditioning system to enhance fuel efficiency. (P. 412, 421) To improve air con-
ditioning performance, adjust the fan speed or turn off Eco drive mode.
■ Automatic return to normal driving mode
If snow mode or sport mode is selected, the driving mode will automatically return
to normal mode when the hybrid system is turned off.
■ S mode
● When the shift range is “5” or lower, holding the shift lever toward “+” sets the
shift range to “6”.
● To prevent the engine from over-revving, upshifting may automatically occur.
■ 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 the D position. (Shifting
the shift lever to the S position cancels the function.)
The engine speed may remain high after releasing the accelerator pedal. This does
not indicate a malfunction.
■ When driving with cruise control or radar cruise control activated
Even when performing the following actions 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. 291, 296)
● When switching the driving mode to sport mode while driving in D position.
(P. 23 9 )
■ If the shift lever cannot be shifted from P
P. 916
■ If S does not come on even after shifting the shift lever to S
This may indicate a malfunction in the hybrid 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.)
