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 operable. 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.

■When enabling the hill start assist system
●If the hill start assist ON indicator does not illuminate or if an incorrect
operation is performed, turn the engine switch to the “LOCK” position
(vehicles without a keyless access with push button start system) or turn
the push-button ignition switch off (vehicles with a keyless access with
push button start system) and then restart the enabling procedure from
.
●If is pressed and held for approximately 30 seconds or more, the
Vehicle stability control (VSC) off indicator and Traction Control System
OFF indicator will turn off and subsequent operations of the switch will be
rejected. In this case, the Vehicle stability control (VSC) system will oper-
ate in normal mode. (oP. 254) To enable , turn the engine switch to
the “ACC” or “LOCK” position (vehicles without a keyless access with
push button start system) or turn the push-button ignition switch off (vehi-
cles with a keyless access with push button start system) and then
restart the engine.
■Operating conditions of the hill start assist system
When the following conditions are met, the hill start assist system will oper-
ate:
●Vehicles with an automatic transmission: The select lever is in D or M
(when starting off forward on while facing uphill) or in R (when starting off
backward while facing downhill).
●Vehicles with a manual transmission: The shift lever is in a position other
than R (when starting off forward while facing uphill) or in R (when start-
ing off backward while facing downhill).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.

When driving
■The hill start assist system will not operate when
The hill start assist system will not operate when any of the following condi-
tions are met:
●Vehicles with an automatic transmission: The select lever is in a position
other than D or M (when facing uphill) or in a position other than R (when
facing downhill).
●Vehicles with a manual transmission: The shift lever is in R (when facing
uphill) or in a position other than R (when facing downhill).
●Vehicles with an automatic transmission: The accelerator pedal is
depressed.
●The parking brake is applied.
●Vehicles with a manual transmission: The clutch is engaged.
●Approximately 2 seconds have elapsed since the brake pedal was
released.
●The hill start assist ON indicator is not illuminated.
●Vehicles without a keyless access with push button start system: The
engine switch is turned to the “ACC” or “LOCK” position.
●Vehicles with a keyless access with push button start system: The push-
button ignition switch is turned to “ACC” mode or turned off.
■Notes for the hill start assist system
●A slight jolt may be felt when starting off backward with the select lever in
R (vehicles with an automatic transmission) or the shift lever in R (vehi-
cles with a manual transmission) and then moving forward.
●If the braking power of the hill start assist system is insufficient, depress
the brake pedal.
●While the vehicle is stopped, make sure to depress the brake pedal.
■The system may be malfunctioning when
In the following situations, the system may be malfunctioning. Have the vehi-
cle inspected by your SUBARU dealer.
●The slip indicator is illuminated.
●The hill start assist ON indicator turns off and a buzzer sounds.

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.

Interior features
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
■Air conditioning filter
oP. 364
WARNING
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
CAUTION
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.

293 3-1. Using the air conditioning system and defogger
3
Interior features
■The defoggers can be operated when
Vehicles without a keyless access with push button start system
The engine switch is in the “ON” position.
Vehicles with a keyless access with push button start system
The push-button ignition switch is in “ON” mode.
■The outside rear view mirror defoggers (vehicles with outside rear view
mirror defoggers)
Turning the rear window defogger on will turn the outside rear view mirror
defoggers on.
■When continuous operation is set (vehicles with an automatic air con-
ditioning system)
During continuous operation, the defogger stops operating for 2 minutes
after every 15 minutes of continual operation. Even during the 2 minutes that
operation stops, the operating light remains illuminated. The rear window
defogger will continue to operate in this cycle until it is turned off.
■Customization that can be configured at SUBARU dealer (vehicles with
an automatic air conditioning system)
The rear window defogger can be set to 15-minute operation or continuous
operation. (Customizable features oP. 493)
WARNING
■When the outside rear view mirror defoggers are on (vehicles with out-
side rear view mirror defoggers)
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
CAUTION
■To prevent battery discharge
Do not leave the rear window defogger on longer than necessary when the
engine is stopped.
