When driving
Automatic transmission
Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
Floor shift type
While the engine switch is on, depress the brake pedal and
move the shift lever.
Column-shift type
While the engine switch is on, depress the brake pedal and
move the shift lever.

Changing shift ranges in S modeShift the shift lever to the S position and operate the shift lever. Floor shift type Upshifting
Downshifting
■Shift position uses
*1: To improve fuel consumption and reduce noises, set the shift lever in
D for normal driving.
*2: Selecting shift ranges S mode restricts the upper limit of the possiblegear ranges, control engine braking forces, and prevents unneces-
sary upshifting.

Column-shift type
Upshifting
Downshifting
The initial shift range in S mode is automatically set to 5 or 4 (6-speed
models) or 4 (5-speed models) according to vehicle speed. However,
the initial shift range may be set to 3 or 2 (6-speed models) or 3 (5-
speed models) if the AI-SHIFT has operated while the shift lever was
in the D position. (
P. 185)
■ Shift ranges and their functions
A lower shift range will provide greater engine braking forces than a higher
shift range.

When driving
■
Gear range display when driving in S mode
The current gear range is displayed on the combination meter. ( P. 182)
■ When driving with the cruise control system (if equipped)
The engine brake will not operate in the S mode, even when downshifting to
5 or 4 (6-speed models) or 4 or 3 (5-speed models). ( P. 223)
■ If the shift lever cannot be shifted from P
P. 643
■ 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 Toyota dealer, immediately.
(In this situation, the vehicle will operate as if the shift lever is in D.)
■ AI-SHIFT
The AI-SHIFT automatically shifts the gear to the optimal position according
to the driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D posi-
tion. (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.
■ Downshifting restrictions wa rning 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.)

NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 651)
■ While driving
●When the voltmeter indicates more than 19 V or less than 9 V, the battery
may be malfunctioning. Have your vehicle checked at your Toyota dealer.
● When the engine oil pressure gauge does not work properly, immediately
stop the engine and contact your Toyota dealer.
● When the automatic transmission fluid temperature gauge needle continu-
ally points higher than normal, immediately contact your Toyota dealer. (if
equipped)

■Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. ( P. 609)
*1: These lights turn on when the engine switch is turned to the ON
position to indicate that a system check is being performed. They
will turn off after the engine is started, or after a few seconds. There
may be a malfunction in a system if a light does not come on, or if
the lights do not turn off. Have the vehicle inspected by your Toyota
dealer for details.
*2: Vehicles with multi-information display
*3: Vehicles without multi-information display
*4: Vehicles without tachometer
*5: The indicator flashes to indicate that the system is operating.
*6: The indicator comes on to indicate a malfunction.
*7: For 2WD models, even though there is no function of deactivatingthe curtain shield airbags in a vehicle rollover, the RSCA OFF indi-
cator turns on briefly when the engine switch is turned to the ON
position. But this is not a malfunction.
