2-1. Driving procedures
WARNING
●On vehicles with a manual transmission, do not shift the shift lever to R
while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
●Do not shift the select lever to D (vehicles with an automatic transmission)
or shift lever to 1 (vehicles with a manual transmission) while the vehicle is
moving backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
●On vehicles with a manual transmission, do not release the clutch pedal
too quickly. Doing so may propel the vehicle forward, possibly causing an
accident.
●Moving the select lever to N (vehicles with an automatic transmission) or
shift lever to neutral (vehicles with a manual transmission) while the vehi-
cle is moving will disengage the engine from the transmission. Engine
braking is not available when N or neutral is selected.
●During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
●Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( →P. 175, 181)
●Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents,
resulting in death or serious injury.

2-1. Driving procedures
WARNING
■If you hear a squealing or scraping noise (brake pad wear limit indica-
tors)
Have your SUBARU dealer check and replace the brake pads as soon as
possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded. ( →P. 151)
■Breaking-in of new brake pads and linings
A safe location and situation should be selected for break-in driving.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P or N (vehicles with an automatic
transmission only) or neutral (vehicles with a manual transmission), the
vehicle may accelerate suddenly and unexpectedly, causing an accident.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
●On vehicles with an automatic transmission, in order to prevent accidents
due to the vehicle rolling away, always keep depressing the brake pedal
while the engine is running, and apply the parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

2-1. Driving procedures
WARNING
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Inhaling exhaust gases may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
●The exhaust system should be checked occasionally. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise,
be sure to have the vehicle inspected and repaired by your SUBARU
dealer. Failure to do so may allow exhaust gases to enter the vehicle,
resulting in death or a serious health hazard.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the select
lever or shift lever, or depress the accelerator pedal, this could cause an
accident or fire due to engine overheating. Additionally, if the vehicle is
parked in a poorly ventilated area, exhaust gases may collect and enter the
vehicle, leading to death or a serious health hazard.

2-1. Driving procedures
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■When the keyless access with push button start system indicator light
flashes in yellow
The system may be malfunctioning. Have the vehicle inspected by your
SUBARU dealer immediately.
■If the access key battery is depleted
→P. 330
■If the keyless access with push button start system has been deacti-
vated in a customized setting
→ P. 401
■Immediately after reconnecting the battery terminals due to replacing
the battery and so forth
The engine may not start. If this occurs, turn the push-button ignition switch
to “ON” mode, and start the engine after waiting at least 10 seconds. Idling
may be unstable immediately after the engine starts, however, this is not a
malfunction. The keyless access with push button start
system indicator light (green) will flash
quickly.
Vehicles with an automatic transmis- sion
Check that the select lever is set in P.
Press the push-button ignition switch
while turning the steering wheel left andright.
Vehicles with a manual transmission
Press the push-button ignition switch
while turning the steering wheel left andright.

When driving
WARNING
■When starting the engine
Always start the engine while sitting in the driver's seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Caution when driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the engine off while the vehicle is moving, turn the
engine switch only to the “ACC” position to stop the engine. An accident may
result if the engine is stopped while driving.
CAUTION
■To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long periods
of time without the engine running.
■When starting the engine
●Do not crank the engine for more than 10 seconds at a time. This may
overheat the starter and wiring system.
If the engine does not start, turn the engine switch to the “LOCK” position
and try to start the engine again after waiting for 10 seconds or more.
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your SUBARU dealer immediately.

When driving
Instrument panel light controlThe brightness of the instrument panel lights can be adjusted. Brighter
Darker
■The brightness of the instrument panel lights
When the parking lights or the headlights turn on, the instrument panel lights
will dim. However, when the instrument panel brightness control dial is
turned to the up most position, the instrument panel lights will not dim even
when the parking lights or headlights turn on.
■Fuel gauge
●When the indicator needle is close to “E”, promptly refuel the vehicle.
●The relationship between the indicator needle and the consumed amount
(remaining fuel) is not always accurate. Only use it as a reference.
●When the vehicle is on an incline or curve, sudden acceleration and
stops and so forth cause the fuel inside the tank to move which may
cause the indicator needle to move up and down.
CAUTION
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
●The engine may be overheating if the temperature gauge is in the red
zone (H). In this case, immediately stop the vehicle in a safe place, and
check the engine after it has cooled completely. ( →P. 409)

■Overheating
If you observe the following, your vehicle may be overheating.
●The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
●Steam is coming from under the engine hood.
WARNING
■To prevent an accident or injury when inspecting under the engine
hood of your vehicle
●If steam is seen coming from under the engine hood, do not open the
engine hood until the steam has subsided. The engine compartment may
be very hot, causing serious injury such as burns.
●Keep hands and clothing away from the fan and other belts while the
engine is running.
●Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( →P. 422)
Have the vehicle checked at the nearest SUBARU dealer as soon
as possible.STEP 5
