! Braking when a tire is punctured
Do not depress the brake pedal suddenly when a tire
is punctured. This could cause a loss of control of the
vehicle. Keep driving straight ahead while gradually
reducing speed. Then slowly pull off the road to a safe
place.
! Brake system
! Two separate circuits
Your vehicle has two separate circuit brake systems.
Each circuit works diagonally across the vehicle. If one
circuit of the brake system should fail, the other half of
the system still works. If one circuit fails, the brake
pedal will go down much closer to the floor than usual
and you will need to press it down much harder. And a
much longer distance will be needed to stop the vehi-
cle.
! Brake booster
The brake booster uses engine manifold vacuum to
assist braking force. Do not turn off the engine while
driving because that will turn off the brake booster, re-
sulting in poor braking power.
The brakes will continue to work even when the brake
booster completely stops functioning. If this happens,
however, you will have to push the pedal much harder
than normal and the braking distance will increase.
! Disc brake pad wear warning indica-
tors
The disc brake pad wear warning indicators on the
disc brakes give a warning noise when the brake pads
are worn.
If a squeaking or scraping noise is heard from the disc
brakes while braking, immediately have your vehicle
checked by your SUBARU dealer.
