When driving
CAUTION
■
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
push and hold the engine switch for more than 3 seconds. However, do not
touch the engine switch while driving except in an emergency. If the engine
stops while the vehicle is being driven, this could lead to an unexpected
accident.
NOTICE
■To prevent battery discharge
Do not leave the engine switch in the ACC or ON position for long periods if
the engine is not running.
■ When starting the engine
●Do not crank for more than 30 seconds at a time. This may overheat the
starter and wiring systems.
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

■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.

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. 190)
■ Shift ranges and their functions
A lower shift range will provide greater engine braking forces than a higher
shift range.

■Gear range display when driving in S mode
The current gear range is displayed on the combination meter. ( P. 187)
■ 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. 221)
■ If the shift lever cannot be shifted from P
P. 627
■ 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.)
■ 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.)
