WARNING
■After adjusting the angle of the rear wing
Make sure that the bolts and nuts are tightened securely. If they are not, the
rear wing may come off while driving, possibly leading to an accident.
CAUTION
■Handling of the rear wing
● Do not push or pull the rear wing with excessive force. Doing so may dam-
age the rear wing.
● When waxing the vehicle, be careful not to leave any residual wax
between the wing and wing end-plates.
■ When adjusting the angle of the rear wing
Observe the following precautions. Otherwise, the rear wing may be dam-
aged.
● Make sure to loosen the rear nuts and bolts before adjusting the angle of
the rear wing.

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 combined 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 available 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 avail-
able 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 trunk whenever possible.
● Be sure all items are secured in place.
● To maintain vehicle balance while driving, position luggage
evenly within the luggage compartment.
● For better fuel economy, do not carry unnecessary weight.

(6)If your vehicle will be towing a trailer, 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.
(→ P. 492)
SUBARU does not recommend towing a trailer with your vehicle. Your
vehicle is not designed for trailer towing.
Example on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are
riding in your vehicle, which has a total load capacity of 699 lb. (317
kg), the available amount of cargo and luggage load capacity will be
as follows:
699 lb. - 366 lb. = 333 lb. (317 kg -166 kg = 151 kg)
In this condition, if 2 more passengers with the combined weight of
258 lb. (117 kg) get on, the available cargo and luggage load will be
reduced as follows:
333 lb. - 258 lb. = 75 lb. (151 kg - 117 kg = 34 kg)
As shown in the example above, if the number of occupants
increases, the cargo and luggage load will be reduced by an amount
that equals the increased weight due 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.

WARNING
■Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Stow cargo and luggage in the trunk whenever possible.
●To prevent cargo and luggage from sliding forward during braking, do
not stack anything in the enlarged trunk. Keep cargo and luggage low,
as close to the floor as possible.
●When you fold down the rear seats, long items should not be placed
directly behind the front seats.
●Never allow anyone to ride in the enlarged trunk. It is not designed for
passengers. They should ride in their seats with their seatbelts prop-
erly fastened. Otherwise, they are much more likely to suffer death or
serious bodily injury, in the event of sudden braking, sudden swerving
or an accident.
●Do not place cargo or luggage in or on the following locations as the
item may get under the clutch, 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:
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the rear shelf
• On the instrument panel
• On the dashboard
●Secure all items in the occupant compartment, as they may shift and
injure someone during sudden braking, sudden swerving or an acci-
dent.

WARNING
■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 not apply the load unevenly. Improper
loading may cause deterioration of steering or braking control which
may cause death or serious injury.

Vehicle load limits
■Total load capacity and seating capacity
These details are described on the tire and loading information label.
(→ P. 382)
WARNING
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the tires, 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
Total load capacity means the combined weight of occupants, cargo
and luggage.
■Seating capacity
Seating capacity means the maximum number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
■Towing capacity
SUBARU 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.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires.
Make sure to install 4 tires that are of the specified size, and that
all 4 tires are the same for the following items:
•Size
• Circumference
• Speed symbol
• Load index
• Construction
• Manufacturer
• Brand (tread pattern)
• Degrees of wear
Also, make sure to use tire chains that match the size of the tires.
■ Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.

278 2-5. Driving information
BRZ_U (A4450BE-A)
●Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle's roof, chassis,
around the tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes
before getting in the vehicle.
● If a door is opened and closed when its side window is frozen,
the window safety device will operate and the side window
open/close function linked to door operation may not operate
correctly. If this occurs, perform the following after the ice has
melted.
Open the side window until it is approximately halfway open
with the door closed.
Fully close the window by pulling the switch up to the one-
touch closing position and continue holding the switch for 1
second or more after the window fully closes.
The window position is reset and the safety device operations will
be released.
■When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to
road conditions.
■ When parking the vehicle (in the winter time or in the cold
latitudes)
Park the vehicle and move the select lever to P (automatic trans-
mission) or shift lever to 1 or R (manual transmission) without
setting the parking brake. The parking brake may freeze up, pre-
venting it from being released. If necessary, block the wheels to
prevent inadvertent sliding or creeping.

Tire chains
Tire chains cannot be used on your vehicle because of the lack of
clearance between the tires and vehicle body.
When tire chains cannot be used, use of another type of traction
device (such as spring chains) may be acceptable if use on your vehi-
cle is recommended by the device manufacturer, taking into account
tire size and road conditions.
Follow the device manufacturer's instructions, especially regarding
maximum vehicle speed.
To help avoid damage to your vehicle, drive slowly, readjust or
remove the device if it is contacting your vehicle, and do not spin your
wheels. Damage caused to your vehicle by use of a traction device is
not covered under warranty.
Make certain that any traction device you use is an SAE class “S”
device, and use it on the rear wheels only.
Always use the utmost care when driving with a traction device. Over-
confidence because you are using a traction device could easily lead
to a serious accident.
Selecting tire chainsWe recommend that you consult your SUBARU dealer for information
about the chains that you can use.

■Refueling in cold weather
To help prevent moisture from forming in the fuel system and the risk of its
freezing, use of an antifreeze additive in the fuel tank is recommended dur-
ing cold weather.
Use only additives that are specifically designed for this purpose. When an
antifreeze additive is used, its effect lasts longer if the tank is refilled when-
ever the fuel level reaches half empty.
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the specified size, and that are the same for the following
items:
•Size
• Circumference
• Speed symbol
• Load index
• Construction
• Manufacturer
• Brand (tread pattern)
• Degrees of wear
●Maintain the recommended level of air pressure.
●Use snow tires on all, not just some wheels.
