Automatic Transmission
Select a shift position appropriate for the driving conditions.
Shifting the shift lever
While the “ENGINE
START STOP” switch is
in IGNITION ON
mode, depress the brake
pedal and move the shift
lever.
Shift position uses
*1: Shifting to the D position allows the system to select a gear suitable
for the
driving conditions. Setting the shift lever to the D position is recommended
for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the
possible
gear ranges, controls engine braking forces, and prevents unnecessary
upshifting.
Changing shift ranges in S mode
Shift the shift lever to the S mode driving position and operate the shift lever.
1. Upshifting.
2. Downshifting.
The initial shift range in S mode is set automatically to 5 or 4 according to vehicle speed. However, the initial shift range may be set to 3 if AI-SHIFT has operated while the shift lever was in the D position.
Shift ranges and their functions
Automatically selecting gears between 1 and 6 according to vehicle speed and driving conditions. However, the gear is limited according to selected shift range.
- You can choose from 6 levels of engine braking force.
- A lower shift range will provide greater engine braking force than a higher shift range, and the engine speed will also increase.
Downshifting restrictions warning buzzer (in the 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. (The warning buzzer will sound twice.)
When driving with the cruise control system or dynamic radar cruise control system
The engine brake will not operate in the S mode, even when downshifting to 5 or 4.
If theindicator does not come
on even after shifting the shift lever to S
mode driving position
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 as manner as when
the
shift lever is in D.)
S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets
the shift
range to 6.
- To prevent excessive engine speed, a function was adopted that automatically selects a higher shift range before 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.
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 mode driving position cancels the function.)
