SIENNA_U (OM45477U)
CAUTION
■Child restraint precautions
● Do not use the seat belt extender when installing a child restraint system
on the front or rear passenger seat. If installing a child restraint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause death or seri-
ous injury to the child or other passengers in the event of a sudden stop,
sudden swerve or an accident.
● Do not allow the child to lean his/her head or any part of his/her body
against the side door or the area of the seat, front and side pillars or roof
side rail from which the SRS side airbags or curtain shield airbags deploy
even if the child is seated in the child restraint system. It is dangerous if
the SRS side airbags and curtain shield airbags inflate, and the impact
could cause death or serious injury to the child.
● Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop, sudden swerve or an accident.

CAUTION
■When loading cargo
Observe the following precautions:
●Place the cargo so that its weight is distributed evenly between the
front and rear axles.
●If loading long or wide cargo, never exceed the vehicle overall length
or width. (P. 784)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the roof luggage carrier will make the center of grav-
ity of the vehicle higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehicle correctly
and result in death or serious injury.
●If driving for a long distance, on rough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
●Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo (vehicles with moon roof)
Be careful not to scratch the surface of the moon roof.

Silencing the sound (type B and C)Press .
Press the button again to turn the system back on.
■ When the battery is disconnected (type A only)
All preset stations are erased.
■ Radio antenna type
● Detachable antenna (type A and B)
To remove a detachable antenna, carefully turn it counterclockwise.
● Wire antenna (type C)
The radio antenna is mounted inside the rear quarter window.
■ Reception sensitivity
● Type B and C Cargo loaded on the roof luggage carrier, especially
metal objects, may adversely affect the reception of XM
® Satellite Radio.
● Maintaining perfect radio reception at all times is difficult due to the con-
tinually changing position of the antenna, differences in signal strength
and surrounding objects, such as trains, transmitters, etc.
● Type C The radio antenna is mounted inside the rear quarter window.
To maintain clear radio reception, do not attach metallic window tinting or
other metallic objects to the antenna wire mounted inside the rear quarter
window.

■Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
● The vehicle is stopped immediately after turning.
● The vehicle is on an inclined surface.
● The vehicle is in a place where the earth’s magnetic field is subject to
interference by artificial magnetic fields (underground car park/parking
lot, under a steel tower, between buildings, roof car park/parking lot, near
an intersection, near a large vehicle, etc.).
● The vehicle has become magnetized.
(There is a magnet or metal object near the trip information display.)
● The battery has been disconnected.
● A door is open.
CAUTION
■While driving the vehicle
Do not adjust the display. Be sure to adjust the display only when the vehicle
is stopped.
■ When doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the
neighborhood. Do not violate any local traffic rules while performing circling
calibration.

NOTICE
■
To avoid a compass malfunctions
Do not place magnets or any metal objects near the roof of the vehicle.
Doing this may cause a malfunction of the compass sensor.
■ To ensure normal operation of the compass
● Do not perform circling calibration of the compass in a place where the
earth’s magnetic field is subject to in terference by artificial magnetic fields.
● During calibration, do not operate electric systems (moon roof, power win-
dows, etc.) as they may interfere with the calibration.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
● Before washing the vehicle:
• Fold the mirrors.
• Turn off the power back door system. (if equipped)
• Turn off the power sliding door system. (if equipped)
Make sure to re-install the antenna and extend the mirrors before driv-
ing.
● Brushes used in automatic car washes may scratch the vehicle surface
and harm your vehicle’s paint.
Perform the following to protect the vehicle and maintain it in prime
condition:
● Working from top to bottom, liber ally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any
dirt and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
● Wipe away any water.
● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehi-
cle body is cool.
