CAUTION
■After returning the rear seatbacks or installing seats
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Make sure the seatback is securely locked by pushing it forward and rear-
ward on the top.
● Check that the seat belts are not twisted or caught in the seatback.
● Make sure the seat is locked in place by trying to shake the seatback and
lift up the seat cushion.
■ Removing the second seats
●Do not leave a seat in the vehicle if it has been disengaged from the floor.
● Do not sit on or place anything on a seat that has been removed from the\
vehicle.
■ 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.
● Power third seats: Do not continue the stowing operation when the indica-
tor above the stowing switch and returning switch comes on or flashes. An
object or a person may be caught in the seat.
● Power third seats: During the stowing operation, to prevent the vehicle
from moving, do not shift the shift lever out of P with the engine switch in
the “ON” position (vehicles without a smart key system) or the “ENGINE
START STOP” switch in IGNITION ON mode (vehicles with a smart key
system).

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. 795

226 2-1. Driving procedures
SIENNA_OM_OM45483U_(U)
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is acci-
dentally depressed.
■ Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the br ake pedal to slow down the vehicle.
● It may be difficult to control your vehicle.
● The vehicle may make abnormal sounds or vibrations.
● The vehicle may lean abnormally.
Information on what to do in case of a flat tire. ( P. 759, 761)

■When the “ENGINE START STOP” s witch 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. 708
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,
press and hold the “ENGINE START STOP” switch for more than 2 seconds,
or press it briefly 3 times or more in succession. ( P. 795)
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.

Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
■Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
■TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
■Hill-start assist control (if equipped)
P. 337
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the engine
off. The EPS system should return to normal within 10 minutes.
CAUTION
■ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when ABS is oper ating may exceed that of normal
conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or roads with uneven surfaces
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
