Driving
■Driving on a downhill
On declines, there may be case where the vehicle shifts down automatically to obtain
engine braking. As a result of the down shifting, the engine speed may increase.
■Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in
second start mode.
■S mode
When the shift range is 5 or lower, holding th e shift lever toward “+” sets the shift range to
6.
■AI-SHIFT
AI-SHIFT automatically shifts the gear to the suitable position according to driver perfor-
mance 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.)
■When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.

be restricted. In some circumstances, downshifting may not be possible even when the
shift lever is operated. (A buzzer will sound twice.)

It may indicate a malfunction in the system. Contact your Lexus dealer.
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: P. 5 8 6 )
The sensor may not function properly if an
object is placed on the sensor, or anything that
