WARNING
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the brake booster device does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase.
Have your brakes fixed immediately.
CAUTION
■Pre-driving check
Trapping small animals in the cooling fan and belts of the engine may result
in a malfunction. Check that no small animal enters the engine compartment
and under the vehicle before starting the engine.
■ When driving the vehicle
Vehicles with an automatic transmission
●If the accelerator and brake pedals are depressed at the same time, driv-
ing torque may be restrained. This is not a malfunction.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.

■ If the engine does not start
The engine immobilizer system may not have been deactivated. ( →P. 82)
Contact your SUBARU dealer.
■ Steering lock
After turning the push-button ignition switch off and opening and closing the
doors, the steering wheel will be locked due to the steering lock function.
Operating the push-button ignition switch again automatically cancels the
steering lock. Vehicles with an automatic transmission:
Check that the select lever is securely set
in P. The engine may not start if the select
lever is displaced out of P. The keyless
access with push button start system indi-
cator light (green) will flash quickly.

“TRACK” mode
Your vehicle is equipped with two types of control modes to accom-
modate various driving preferences. The control modes can be
selected with the “TRACK” switch. Normal mode allows secure and
smooth normal driving. When the switch is pressed and held for 1
second or more, “TRACK” mode is activated. Control characteristics
such as the Vehicle stability control (VSC) and TRAC are adjusted to
afford maneuverability closer to what a driver may desire, while a
sense of security is retained. “TRACK” mode/Normal mode
The “TRACK” indicator and Vehi-
cle stability control (VSC) off indi-
cator come on when in “TRACK”
mode.
To change back to normal mode
while in “TRACK” mode, press
or the “TRACK” switch.
Turning off both TRAC and Vehicle stability control (VSC) systems
To turn the TRAC and Vehicle stability control (VSC) systems off,
press and hold for more than 3 seconds while the vehicle is
stopped.
The Traction Control System OFF indicator light and the Vehicle sta-
bility control (VSC) off indicator light will come on.
However, on vehicles with an automatic transmission, the brake LSD
function will remain on.
Press the button again to turn the systems back on.

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.

2-5. Driving information
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.
