Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working in the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■When working near the electric cooling fans or radiator grille
Vehicles without a keyless access with push button start system: Be sure the
engine switch is off. With the engine switch in the “ON” position, the electric
cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. (oP. 342)
Vehicles with a keyless access with push button start system: Be sure the
push-button ignition switch is off. With the push-button ignition switch in
“ON” mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the coolant temperature is high. (oP. 342)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
CAUTION
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.

■Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, before recharging:
●If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
●Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
■After recharging/reconnecting the battery (vehicles with a keyless
access with push button start system)
●Unlocking the doors using the keyless access with push button start sys-
tem may not be possible immediately after reconnecting the battery. If
this happens, use the remote keyless entry system or the mechanical
key to lock/unlock the doors.
●Start the engine with the push-button ignition switch in “ACC” mode. The
engine may not start with the push-button ignition switch turned off. How-
ever, the engine will operate normally from the second attempt.
●The push-button ignition switch mode is recorded by the vehicle. If the
battery is reconnected, the vehicle will return the push-button ignition
switch mode to the status it was in before the battery was disconnected.
Make sure to turn off the engine before disconnect the battery. Take extra
care when connecting the battery if the push-button ignition switch mode
prior to discharge is unknown.
If the engine will not start even after multiple attempts, contact your
SUBARU dealer.
