SIENNA_OM_OM45472U_(U)
■Mirror angle can be adjusted when
Vehicles without a smart key system
The engine switch is in the “ACC” or “ON” position.
Vehicles with a smart key system
The “ENGINE START STOP” switch is in ACCESSORY or IGNITION ON
mode.
■ When the mirrors are fogged up (veh icles with outside rear view mirror
defoggers)
Turn on the mirror defoggers to defog the mirrors. ( P. 419)
■ Automatic adjustment of the mirror angle (vehicles with driving posi-
tion memory)
A desired mirror face angle can be entered to memory and recalled automat-
ically by the driving position memory. ( P. 120)
■ Auto anti-glare function (vehicles with auto anti-glare inside rear view
mirror)
When the anti-glare inside rear view mirror is set to automatic mode, the out-
side rear view mirrors will activate in conjunction with the anti-glare inside
rear view mirror to reduce reflected light. ( P. 138)
■ Linked mirror function when reversing (if equipped)
The outside rear view mirrors will automatically angle downwards when the
vehicle is reversing in order to give a better view of the ground. However,
this function will not operate when the mirror select switch is in the n\
eutral
position (between “L” and “R”).

CAUTION
■When driving the vehicle
Observe the following precautions while driving.
Failing to do so may result in loss of control of the vehicle and cause an acci-
dent, resulting in death or serious injury.
● Do not adjust the mirrors while driving.
● Do not drive with the mirrors folded.
● Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
■ When a mirror is moving
To avoid personal injury and mirror malfunction, be careful not to get your
hand caught by the moving mirror.
■ When the mirror defoggers are oper ating (vehicles with outside rear
view mirror defoggers)
Do not touch the rear view mirror surfaces, as they can become very hot and
burn you.

SIENNA_OM_OM45472U_(U)
CAUTION
■When driving the vehicle
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 237)
● Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents,
resulting in death or serious injury.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.
● AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for off-road driving. Proceed with all
due caution if it becomes unavoidable to drive off-road.
● AWD models: Do not drive across a river or through other bodies of water.
This may cause electric/electronic components to short circuit, damage
the engine or cause other serious damage to the vehicle.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.

*1: These lights turn on when the “ENGINE START STOP” switch isturned to IGNITION ON mode (vehicles with a smart key system) or
the engine switch is turned to the “ON” position (vehicles without a
smart key system) to indicate that a system check is being per-
formed. 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.

*4: In order to confirm operation, the BSM outside rear view mirror indi-
cators illuminate in the following situations:
• When the “ENGINE START STOP” switch is turned to IGNITION
ON mode (vehicles with a smart key system) or the engine switch
is turned to the “ON” position (vehicles without a smart key sys-
tem) while the BSM main switch is set to ON.
• When the BSM main switch is set to ON while the “ENGINE START STOP” switch is in IGNITION ON mode (vehicles with a
smart key system) or the engine switch is turned to the “ON”
position (vehicles without a smart key system).
If the system is functioning correctly, the BSM outside rear view mir-
ror indicators will turn off after a few seconds.
If the BSM outside rear view mirror indicators do not illuminate or do
not turn off, there may be a malfunction with the system.
If this occurs, have the vehicle inspected by your Toyota dealer.

●
In the situations below, the system may not be able to correctly detect the
surrounding brightness levels, and may flash or expose nearby pedestri-
ans to the high beam. Therefore, you should consider turning the high
beam on or off manually rather than relying on the Automatic High Beam
system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or ca mera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are changing color, or are not aimed properly.
• When driving through an area of intermittently changing brightness and darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is lifting or tilting, due to a flat tire, a trailer being towed etc.
• The Automatic High Beam indicator is flashing.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or distress to other drivers or pedestrians nearby.

■If the Automatic High Beam indicator flashes...
It may indicate a malfunction in the system. Contact your Toyota dealer.
■ Customization that can be configured at Toyota dealer or by the multi-
information display
The Automatic High Beam can be turned off.
(Customizable features P. 831)
■ Temporary lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
To lower the sensitivity, push and hold on the inside rear view mirror
for 15 to 20 seconds, and release. The indicator light on the inside rear view
mirror will flash to indicate that the sensitivity has been lowered.
Vehicles without a smart key system:
When the engine switch is turned to the “LOCK” position, the sensitivity will
be returned to its normal level.
Vehicles with a smart key system:
When the “ENGINE START STOP” switch is turned off, the sensitivity will be
returned to its normal level.
