■When replacing light bulbs
SUBARU recommends that you use genuine SUBARU products designed
for this vehicle.
Because certain bulbs are connected to circuits designed to prevent over-
load, non-genuine parts or parts not designed for this vehicle may be unus-
able.
■Removing and installing the luggage trim cover and trunk lid panel cover clip
WARNING
■Replacing light bulbs
●Turn off the lights. Do not attempt to replace the bulb immediately after
turning off the lights.
The bulbs become very hot and may cause burns.
●Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
●Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
■When changing the back-up lights
Stop the engine and wait until the exhaust pipe has cooled sufficiently. The
lights are located near the exhaust pipe and touching a hot exhaust pipe can
cause burns.

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.
