■When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.
■ If the electronic key battery is depleted
P. 693
CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If the vehicle begins to slide due to engine failure or other circumstances, do
not lock or open the doors until the vehicle reaches a safe and complete
stop. Activation of the steering lock in this circumstance may lead to an acci-
dent, 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 START STOP” switch for more than 3 seconds.
However, do not touch the “ENGINE START STOP” switch while driving
except in an emergency. Turning the engine off while driving will not cause
loss of steering or braking control, but the power assist to these systems will
be lost. This will make it more difficult to steer and brake, so you should pull
over and stop the vehicle as soon as it is safe to do so.

Shift ranges and their functions
●Automatically selecting gears between 1 and 6 according to
vehicle speed and driving conditi ons. But, 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 br aking force than
a higher shift range, and the engine speed will also increase.
■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 auto-
matically selects a higher shift range before the engine speed becomes
too high.
● To protect the automatic transaxle, a function is adopted that automati-
cally selects a higher shift range when the fluid temperature is high.
■ When driving with the cruise contro l or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( P. 293, 298)
■ If the shift lever cannot be shifted from P
● P. 764
● Vehicles with AUTO ACCESS SEAT : If the AUTO ACCESS SEAT has
not been locked in place after being stowed, the shift lever cannot be
shifted from P.

SIENNA_U (OM45477U)
■Daytime running light system (if equipped)
● To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the engine is started and
the parking brake is released. Daytime running lights are not designed for
use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help
improve fuel economy.
■ Headlight control sensor (if equipped)
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
