4-1. Maintenance and care
WARNING
■When washing the vehicle
●Do not wash the engine compartment and area adjacent to it. If water
enters the engine air intake or electrical parts it will cause engine trouble or
a malfunction of the power steering.
●When washing the vehicle, the brakes may get wet. As a result, the brake
stopping distance will be longer. To dry the brakes, drive the vehicle at a
safe speed while lightly depressing the brake pedal to heat up the brakes.
■Precautions regarding the exhaust pipes
Exhaust gasses cause the exhaust pipes and rear bumper diffusers to
become quite hot.
When washing the vehicle, be careful not to touch the pipes and diffusers
until they have cooled sufficiently, as touching hot exhaust pipes and rear
bumper diffusers can cause burns.
CAUTION
■To prevent paint deterioration and corrosion on the body and compo-
nents (aluminum wheels etc.)
●Wash the vehicle immediately in the following cases:

5-1. Essential information
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 commercial 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.

5-1. Essential information
■Before emergency towingRelease 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.

From the rear
Never tow a vehicle from the front with
the rear wheels on the ground.Use a tow-
ing dolly under the rear wheels.

nents have adequate clearance to pre-
vent contact with the road surface under
all conditions.
