Driving On A Downhill; Second Start Mode Automatic Deactivation; Downshift Restriction Warning Buzzer (S Mode); If The “S” Indicator Does Not Come On Even After Shifting The Shift Lever To S - Lexus GX 460 User Manual

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 downshifting, 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 the 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.
(P. 218, 221)
If the shift lever cannot be shifted from P
■
P. 548
If the "S" indicator does not come on even after shifting the shift lever to S
■
This may indicate a malfunction in the automatic transmission system. Have the vehicle
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.)

Downshift restriction warning buzzer (S mode)

■
To help ensure safety and driving performance, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever is operated. (A buzzer will sound twice.)
CAUTION
When driving on slippery road surfaces
■
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in an
accident.
