■
Engine speed while driving (vehicl es with an automatic transmission)
In the following conditions, the engine speed may become high while driving.
This is due to automatic up-shifting control or down-shifting implementation
to meet driving conditions. It does not indicate sudden acceleration.
● The vehicle is judged to be driving uphill or downhill
● When the accelerator pedal is released
● When driving on curves
● When the brake pedal is firmly depressed
■ New vehicle break-in driving (the first 1000 miles [1600 km])
The performance and long life of your vehicle are dependent on how you
handle and care for your vehicle while it is new. Follow these instructions
during the first 1000 miles (1600 km):
● Do not allow the engine speed to exceed 4000 rpm except in an emer-
gency.
● Do not drive at one constant engine or vehicle speed for a long time,
either fast or slow.
● Avoid starting suddenly and rapid acceleration, except in an emergency.
● Avoid hard braking, except in an emergency.
The same break-in procedures should be applied to an overhauled engine,
newly mounted engine or when brake pads or brake linings are replaced
with new ones.
■ Replacement of brake pad and lining
The front disc brake and the rear disc brake have audible wear indicators on
the brake pads. If the brake pads wear close to their service limit, the wear
indicator makes a very audible scraping noise when the brake pedal is
applied.
If you hear this scraping noise each time
you apply the brake pedal, have the
brake pads serviced by your SUBARU
dealer as soon as possible.

■Breaking-in of new brake pads and linings
When replacing the brake pad or lining, use only genuine SUBARU parts.
After replacement, the new parts must be broken in as follows.
Brake pad and lining
While maintaining a speed of 30 to 40 mph (50 to 65 km/h), step on the
brake pedal lightly. Repeat this five or more times.
Parking brake lining
Drive the vehicle at a speed of approximately 22 mph (35 km/h).
With the parking brake release button pushed in, pull the parking
brake lever SLOWLY and GENTLY (pulling with a force of approxi-
mately 33.7 lbf [150 N, 15.3 kgf]).
Drive the vehicle for approximately 220 yards (200 meters) in this
condition.
Wait 5 to 10 minutes for the parking brake to cool down. Repeat this
procedure.
Check the parking brake lever travel. If the parking brake lever
travel is out of the specified range, adjust it by turning the adjusting
nut located on the parking brake lever.
Parking brake lever travel: →P. 501
■ High friction brake pads (if equipped)
The brake pads and discs are desi gned for use under high load conditions.
Therefore, brake noise may be generated depending on the vehicle speed,
braking force and vehicle environment (temperature, humidity, etc.).
■ Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of
brake system needs bedding-down of t he brake shoes periodically or when-
ever the parking brake shoes and/or drum are replaced. Have your
SUBARU dealer perform the bedding down. ( →P. 160)

WARNING
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid, resulting in an accident.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioni ng properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
■ When shifting the select lever or shift lever
●On vehicles with an automatic transmission, be careful not to shift the
select lever with the accelerator pedal depressed. Shifting the select lever
to a gear other than P or N may lead to unexpected rapid acceleration of
the vehicle that may cause an accident and result in death or serious
injury.
● Do not place items in the select lever’s or shift lever’s surrounding area. It
may cause incorrect operation.
● If the select lever’s or shift lever’s boot is pulled out during cleaning, return
it to its previous position. If the select lever’s or shift lever’s boot is left
pulled out, the select lever or shift lever may become difficult to operate.
■ If you hear a squealing or scrapin g 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. 159)
■ Breaking-in of new brake pads and linings
A safe location and situation should be selected for break-in driving.

CAUTION
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
● On vehicles with an automatic transmission, do not race the engine for
more than 5 seconds in any position except the N or P position when the
brake is applied or when chocks are used in the wheels. This may cause
the transmission fluid to overheat.
■ Avoiding damage to the under spoilers (tS models)
On vehicles with under spoilers, be careful when driving, as the ground
clearance will be lower than a vehicle without them as follows:
●Front under spoiler: Ground clearance at the front of each front wheel arch
and the center of the front bumper is lower by approximately 0.4 in. (1 cm)
and 1.6 in. (4 cm), respectively.
● Side under spoilers: Ground clearance at the sides of the vehicle is lower
by approximately 1.2 in. (3 cm).
● Rear under spoilers: Ground clearance at each corner of the rear bumper
is lower by approximately 0.4 in. (1 cm).
■ Replacement of brake pad and lining
If you continue to drive despite the scraping noise from the audible brake
pad wear indicator, it will result in the need for costly brake rotor repair or
replacement.
■ Breaking-in of new brake pads and linings
Pulling the parking brake lever too forcefully may cause the rear wheels to
lock. To avoid this, be certain to pull the lever up slowly and gently.

■Brake (vehicles with brembo brake)
●Painted brake calipers
• When using detergent, use neutral detergent. Do not use hard brushes
or abrasive cleaners, as they will damage the paint.
• Do not use detergent on the brake calipers when they are hot.
• Wash detergent off immediately after use.
● Rust may form if the vehicle is parked with wet brake pads or disc rotors,
causing them to stick. Before parking the vehicle after it is washed, drive
slowly and apply the brakes several times to dry the parts.
■ CFRP (Carbon Fiber Reinforced Plastic) part (if equipped)
●Remove any dirt using a neutral detergent. Do not use hard brushes or
abrasive cleaners. Do not use st rong or harsh chemical cleaners.
● As the CFRP parts may change color if they are exposed to ultraviolet
rays for extended periods of time, SUBARU recommends that your vehi-
cle be stored in a place where it will not be exposed to direct sunlight.
● Do not use wax that contains abrasives.
■ When washing the vehicle
Wear rubber gloves and use a hand brush when washing down underbody,
inner fenders and suspension to effectively remove mud and dirt off.

■
Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Fluid type
FMVSS No.116 DOT 3 or DOT 4 brake fluid
ItemsClean funnel
■ Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
WARNING
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets in your eyes, flush your eyes with clean water immediately.
If you still experience discomfort, see a doctor.
CAUTION
■ If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
