CAUTION
■TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When TRAC and VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to ensure vehicle stability and driving force, do
not turn off TRAC and VSC systems unless necessary.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS and VSC systems will not function correctly if different tires are fit-
ted on the vehicle.
Contact your Scion dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

Cargo and luggage
Capacity and distributionCargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity)  (Total weight of occupants)
Steps for Determining Correct Load Limit—
(1) Locate the statement “The co mbined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
(3)Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the av ailable amount of cargo and lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will
be five 150 lb passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400  750 (5  150)
= 650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the
available cargo and luggage load capacity calculated in Step 4.
Take notice of the following information about storage precau-
tions, cargo capacity and load.
●Stow cargo and luggage in the luggage compartment whenever
possible.
● Be sure all items are secured in place.
● Be careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
● For better fuel economy, do no t carry unnecessary weight.

(6) If your vehicle will be towing a tr
ailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle.
Scion does not recommend towing a trailer with your vehicle. Your
vehicle is not designed for trailer towing.
Calculation formula for your vehicle
Cargo capacity
Total load capacity (vehicle
capacity weight) (P. 320)
When 2 people with the combined weight of A lb. (kg) are riding in
your vehicle, which has a total load capacity (vehicle capacity weight)
of B lb. (kg), the available amount of cargo and luggage load capacity
will be C lb. (kg) as follows:
B
*2 lb. (kg)  A*1 lb. (kg) = C*3 lb. (kg)
*1: A = Weight of people
*2: B = Total load capacity
*3: C = Available cargo and luggage load
In this condition, if 2 more pa ssengers with the combined weight of
D lb. (kg) get on, the available ca rgo and luggage load will be reduced
E lb. (kg) as follows:
C lb. (kg)  D*4 lb. (kg) = E*5 lb. (kg)
*4: D = Additional weight of people
*5: E = Available cargo and luggage load

148 2-5. Driving information
As shown in the above example, if the number of occupants
increases, the cargo and luggage load will be reduced by an amount
that equals the increased weight du e to the additional occupants. In
other words, if an increase in the number of occupants causes an
excess of the total load capacity (combined weight of occupants plus
cargo and luggage load), you must reduce the cargo and luggage on
your vehicle.
CAUTION
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-
ment.
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
●Stow cargo and luggage in the luggage compartment whenever possi-
ble.
●Do not stack cargo and luggage in the luggage compartment higher
than the seatbacks.
Such items may be thrown about and possibly injure people in the
vehicle in the event of sudden braking or in an accident.
●Do not place cargo or luggage in or on the following locations as the
item may get under the brake or accelerator pedal and prevent the
pedals from being depressed properly , block the driver’s vision, or hit
the driver or passengers, causing an accident.
• Driver’s feet
• Front passenger or rear seats (when stacking items)
• Instrument panel
• Dashboard
• Auxiliary box or tray that has no lid
●Secure all items in the occupant compartment, as they may shift and
injure someone during emergency braking, sudden swerving or an
accident.

When driving
CAUTION
■Storage precautions
●Never allow anyone to ride in the luggage compartment. It is not
designed for passengers. They should ride in their seats with their seat
belts properly fastened. Otherwise,
they are much more likely to suffer
serious bodily injury, in the event of emergency braking, sudden
swerving or an accident.
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
●Even if the total load of occupant’s weight and the cargo load is less
than the total load capacity, do no t apply the load unevenly. Improper
loading may cause deterioration of st eering or braking control which
may cause death or serious injury.

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information
label. (P. 230)
CAUTION
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the ti res, but also degrade steering and
braking ability, resulting in an accident.
Vehicle load limits include total load capacity, seating capacity,
towing capacity and cargo capacity.
■ Total load capacity (vehicle capacity weight): ( P. 320)
Total load capacity means the combined weight of occupants,
cargo and luggage.
■ Seating capacity: 4 occupants (Front 2, Rear 2)
Seating capacity means the ma ximum number of occupants
whose estimated average weight is 150 lb. (68 kg) per person.
Even if the number of occupants are within the seating capacity,
do not exceed the total load capacity.
■ Towing capacity
Scion does not recommend towing a trailer with your vehicle.
■ Cargo capacity
Cargo capacity may increase or decrease depending on the
weight and the number of occupants.

3Snow tiresFor driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( P. 151)
■Initializing the tire pr essure warning system
Initialize the tires with the tire inflati on pressure adjusted to the specified
level.
■If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire in flation pressure to the speci-
fied level and initialize the tire pressure warning system again.
■When the initialization of the tire pressure warning system has
failed
Initialization can be completed in a few minutes. However, in the follow-
ing cases, the settings has not be en recorded and the system will not
operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Scion
dealer.
●When operating the tire pressure warning reset switch, the tire pres-
sure warning light does not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving for about 20
minutes.
■Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.

Wheels
■When replacing wheels
The wheels of your Scion are equipped with tire pressure warning valves
and transmitters that allow the tire pressure warning system to provide
advance warning in the event of a loss in tire inflation pressure. When-
ever wheels are replaced, tire pressure warning valves and transmitters
must be installed. ( P. 223)
If a wheel is bent, cracked or heavily corroded, it should be
replaced.
Otherwise, the tire may separate from the wheel or cause loss of
handling control.
■ Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and inset
*.
Replacement wheels are available at your Scion dealer.
*: Conventionally referred to as “offset”.
Scion does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
