■
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.

If your vehicle needs to be towed
Emergency towingIf a tow truck is not available in an emergency, your vehicle may be
temporarily towed using a cable or chain secured to the emergency
towing eyelet to move the vehicle to a safe location or to free a stuck
vehicle from sand or snow. This should only be attempted on hard
surfaced roads for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle's wheels, drive train, axles, steering and brakes must be in
good condition.
For vehicles with an automatic transmission, only the front towing
eyelet may be used. Towing eyelet
If towing is necessary, we recommend having your vehicle towed by
your SUBARU dealer or a comme rcial towing service, using a flat
bed truck.
The vehicle must be secured properly with safety chains. Each
safety chain should be equally tightened and care must be taken not
to pull the chains so tightly that the suspension bottoms out.

■Before emergency towing
Release the parking brake.
Shift the select lever to N (vehicles with an automatic transmission)
or shift lever to neutral (vehicles with a manual transmission).
Vehicles without a keyless access with push button start system:
Turn the engine switch to the “A CC” (engine off) or “ON” (engine
running) position.
Vehicles with a keyless access with push button start system: Turn
the push-button ignition switch to “ACC” (engine off) or “ON”
(engine running) mode.
■ If towing a vehicle
Do not tow another vehicle. If towing a vehicle that has broken down is
unavoidable, avoid towing a vehicle that is heavier than your vehicle. Also,
do not pull out a vehicle that has fallen into a ditch.
WARNING
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
● If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.

CAUTION
■To prevent causing serious damage to the transmission in emergency
towing (vehicles with an automatic transmission)
Never tow a vehicle from the rear with four wheels on the ground. This may
cause serious damage to the transmission.
■ To prevent damage to the vehicle
● When towing this vehicle, make sure to observe the following:
• Do not use a wire rope
• Keep vehicle speed below 20 mph (30 km/h) and do not tow for dis-
tances over 19 miles (30 km)
• Tow the vehicle in the forward direction
• Do not apply rope to the vehicle's suspension and so forth
● Do not tow another vehicle, boat (trailer) and so forth, that is heavier than
this vehicle.
■ When towing down a long slope
Use a wheel lift-type or flat bed truck. ( →P. 424, 425)
If a wheel lift-type or flat bed truck is not used, the brakes may overheat,
leading to poor brake performance.
