These hooks are designed to be used
for the cargo net.
The cargo net can be used in a variety
of ways as shown in the illustrations.
The cargo net itself is not included as an
original equipment.
NOTICE
To prevent damage to the hooks,
avoid using them for things other
than the cargo net.
To secure your luggage, use the tie
down hooks as shown above.
See “—Stowage precautions” on page 412
in Section 2 for precautions when loading
luggage.
CAUTION
To avoid personal injury, keep the tie
down hooks folded when not in use.
The roof luggage carrier consists of
roof rails (1) attached to the roof and
sliding cross rails (2).
To adjust the positions of cross rails, do
this.1. Turn the knobs counterclockwise to loosen the cross rails.
2. Slide the cross rails to the desired position for loading the luggages of
various sizes.
3. After adjusting, be sure to tighten the cross rails by turning knobs clockwise.
Follow the manufacturer ’s instructions and
precautions when installing the attach-
ments or their equivalent.

CAUTION
When you load cargo on the roof lug-
gage carrier, observe the following:
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. (See “Dimensions and
weights” on page 512 in Section 8
for information on your vehicle
overall length and width.)
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 the
vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns,
sudden braking or abrupt maneu-
vers, otherwise it may result in loss
of control or vehicle rollover due to
failure to operate this vehicle cor-
rectly.
If driving for a long distance, on
rough roads, or at high speeds,
stop the vehicle now and then dur-
ing the trip to make sure the cargo
remains in its place.
Do not exceed 68 kg (150 lb.) cargo
weight on the roof luggage carrier.
NOTICE
When loading the luggages, be careful
not to scratch the surface of the
moon roof.

CAUTION
Before driving off, make sure that
the parking brake is fully released
and the parking brake reminder
light is off.
Do not leave your vehicle unat-
tended while the engine is running.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to skid or spin.
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.
If you need greater traction while driv-
ing on sand, mud or snow covered
roadways, use tire chains on the front
wheels.
Always check your brakes for effective-
ness immediately after driving across
sand, mud, or water.
If operating in adverse conditions
frequently, vehicle maintenance should
be increased. (See the separate
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.)
CAUTION
Observe the following tire instruc-
tions. Otherwise, an accident may oc-
cur resulting in death or serious inju-
ries.
Keep your tire inflation pressure at
the proper level. (See “Checking
tire inflation pressure” on page 487
in Section 72.)
Do not use tires (including snow
tires) of different brands, sizes,
construction or tread patterns. (See
“Checking and replacing tires” on
page 490 and “Installing snow tires
and chains” on page 494 in Section
72.)

The trailer cargo load should be
distributed so that the tongue load
is 9 to 11% for weight carrying
hitch
(∗

ut i ng hi t ch ( ∗
2) of the total trailer
weight, not exceeding the maximum
load of the following.
Weight carrying hitch158 kg (350 lb.)
Weight distributing hitch
238 kg (525 lb.)
Never load the trailer with more
weight in the back than in the
front. About 60% of the trailer load
should be in the front half of the
trailer and the remaining 40% in the
rear.
HITCHES
If you wish to install a trailer hitch, you
should consult with your Toyota dealer.
Use only a hitch recommended by the
hitch manufacturer and the one which
conforms to the total trailer weight
requirement.
The hitch must be bolted securely to
the vehicle frame and installed accord-
ing to the hitch manufacturer ’s instruc-
tions.
The hitch ball and king pin should have
a light coat of grease.
Toyota recommends removing the trail-
er hitch whenever you are not towing
a trailer to reduce the possibility of
additional damage caused by the hitch
if your vehicle is struck from behind.
After removing the hitch, seal any
mounting holes in the vehicle body to
prevent entry of pollutants such as ex-
haust fumes, dirt, water, etc.
NOTICE
Do not use axlemounted hitches as
they can cause damage to the axle
housing, wheel bearings, wheels or
tires. Also, never install a hitch which
may interfere with the normal function
of an Energy Absorbing Bumper, if so
equipped.
BRAKES AND SAFETY CHAINS
Toyota recommends trailers with
brakes that conform to any applica-
ble federal and state/provincial regu-
lations.

07 SIENNA_U (L/O 0612)

2007 SIENNA from Oct. ’06 Prod. (OM45437U)
A safety chain must always be used
between the towing vehicle and the
trailer. Leave sufficient slack in the
chain for turns. The chain should
cross under the trailer tongue to
prevent the tongue from dropping to
the ground in case it becomes dam-
aged or separated. For correct safety
chain procedures, follow the hitch or
trailer manufacturer ’s recommenda-
tions.
CAUTION
If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.
Never tap into your vehicle’s hy-
draulic system as it would lower its
braking effectiveness.
Never tow a trailer without using a
safety chain securely attached to
both the trailer and the vehicle. If
damage occurs to the coupling unit
or hitch ball, there is danger of the
trailer wandering over into another
lane.
TIRES
Ensure that your vehicle’s tires are
properly inflated. See page 487 in Sec-
tion 7−2 and page 517 in Section 8 for
instructions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.
TRAILER LIGHTS
Trailer lights must comply with federal,
state/provincial and local regulations.
See your local recreational vehicle
dealer or rental agency for the correct
type of wiring and relays for your trail-
er. Check for correct operation of the
turn signals and stop lights each time
you hitch up. Direct splicing may dam-
age your vehicle’s electrical system
and cause a malfunction of your lights.
BREAKIN SCHEDULE
Toyota recommends that you do not
tow a trailer with a new vehicle or a
vehicle with any new power train com-
ponent (engine, transmission, differen-
tial, wheel bearing, etc.) for the first
800 km (500 miles) of driving. MAINTENANCE
If you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load. For this
information, please refer to the
scheduled maintenance information in
the “Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.
Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
PRETOWING SAFETY CHECK
Check that your vehicle remains level
when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle has
an abnormal nose −up or nose −down
condition, and check for improper
tongue load, overload, worn suspension
or other possible causes.
Make sure the trailer cargo is securely
loaded so that it cannot shift.
Check that your rear view mirrors con-
form to any applicable federal, state/
provincial or local regulations. If not,
install the rear view mirrors required
for towing purpose.
