Main Owner’s Manual
Please note that this manual applies to all models and all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not
installed on your vehicle.
All specifications provided in this manual are current at the time of printing.
However, because of the Toyota policy of continual product improvement, we
reserve the right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustrations may differ
from your vehicle in terms of equipment.
Noise from under vehicle after turning off the engine
Approximately five hours after the engine is turned off, you may hear sound
coming from under the vehicle for several minutes. This is the sound of a fuel
evaporation leakage check and, it does not indicate a malfunction.

vehicles are currently available on the market. You should know that Toyota
does not warrant these products and is not responsible for their
performance, repair, or replacement, or for any damage they may cause to,
or adverse effect they may have on, your Toyota vehicle.
This vehicle should not be modified with non-genuine Toyota products.

Notes for the unlocking function
● Gripping the front door handle when wearing a glove may not unlock or
lock the door.
● A sudden approach to the effective range or door handle operation may
prevent the doors from being unlocked. In this case, return the door han-
dle to the original position and check that the doors have unlocked before
pulling the door handle.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after one of the front door handles is gripped
or one of sliding door handles is pulled.
■ When the vehicle is not dr iven for extended periods
● To prevent theft of the vehicle, do not leave the electronic key within 6 ft.
(2 m) of the vehicle.
● The smart key system can be deactivated in advance. ( P. 831)
■ To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not
operate.)

serious injury.
● Make sure the seatback is securely locked by pushing it forward and rear-
ward on the top.

■ Stowing the third seats
● Make sure that the seat path is clear before moving the seat. Otherwise,
injury may result from contact with, or by being pinched by parts of the
seat.
● Manual third seats: Do not sit on the third seat when it is in the stowed
position with the seatback upright.

When driving
SIENNA_OM_OM45472U_(U)
CAUTION
■
When driving the vehicle
● If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by your Toyota dealer
immediately.
● Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Moving the shift lever to N while the vehicle is moving will disengage the
engine from the transmission. Engine braking is not available when N is
selected.
● During normal driving, do not turn off the engine. 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.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 796
