Hill star t assist
The hill start assist system helps to maintain braking force to assist
starting off forward while facing uphill or starting off backward while
facing downhill. As the hill start assist system is initially disabled,
enable the system to make it oper able. The enabled/disabled setting
will be maintained the next time the engine is started.
When the system is enabled,
the hill start assist ON indica-
tor will be illuminated.
■ Enabling the hill start assist system
Park your vehicle in a flat, safe location.
Make sure that the parking brake is securely engaged.
Stop the engine by turning the engine switch to the “LOCK”
position (vehicles without a keyless access with push but-
ton start system) or turning the push-button ignition switch
off (vehicles with a keyless access with push button start
system).
Start the engine and check that the ABS warning light and
slip indicator are off.
Press and hold for
approximately 30 seconds.
Check that both the Vehicle
stability control (VSC) off indi-
cator and Traction Control Sys-
tem OFF indicator illuminate
and then turn off.

WARNING
■Hill start assist system precautions
●Do not overly rely on the hill start assist system. The hill start assist system
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, the hill start assist system is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use
the hill start assist system to hold the vehicle on an incline, as doing so
may lead to an accident.
● Do not stop the engine while the hill start assist system is operating, as the
hill start assist system will stop operating, possibly leading to an accident.

CFRP (Carbon Fiber Reinforced Plastic) parts
● Due to the properties of the carbon fiber used in CFRP parts, the shade
and density of the carbon fiber weave may vary.
● Cleaning and protecting the CFRP parts: →P. 337, 338
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.
● When installing the rear bolts, make sure that both the left and right bolts
are installed to the same position for the desired angle.
● Do not loosen the nuts and bolts on the front side.

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.

■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.

CAUTION
■Repairing or replacing snow tires (vehicles with a tire pressure moni-
toring system)
Request repairs or replacement of snow tires from SUBARU dealers or
legitimate tire retailers.
This is because the removal and attachment of snow tires affects the
operation of the tire pressure warning valves and transmitters.
■Fitting tire chains (vehicles with a tire pressure monitoring system)
The tire pressure warning valves and transmitters may not function cor-
rectly when tire chains are fitted.
