WARNING
Observe the following precautions.
Failure to do so may cause the driver's floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle. Th
is could lead to an accident, resulting in
death or serious injury.
■ When installing the driver's floor mat
● Do not use floor mats designed for ot her models or different model year
vehicles, even if they are SUBARU Genuine floor mats.
● Only use floor mats designed for the driver's seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
● With the engine stopped and the select
lever in P (automatic transmission) or
shift lever in neutral (manual transmis-
sion), fully depress each pedal to the
floor to make sure it does not interfere
with the floor mat.

WARNING
■
Pre-driving check
Check that the engine hood is fully closed and locked.
If the engine hood is not locked properly it may open while the vehicle is in
motion and cause an accident, which may result in death or serious injury.
CAUTION
■When opening the engine hood
● Do not lift up or operate the wipers. Doing so may cause the engine hood
and wipers to contact, scratching the engine hood.
● Use caution when opening the engine hood in windy weather as it may
close suddenly in strong wind.
● Do not attach any accessories other than genuine SUBARU products to
the engine hood. Such additional weight on the engine hood may cause it
to be too heavy to be supported by the supporting rod when opened.
■ When closing the engine hood
Do not apply excessive weight or force when closing the engine hood as
doing so may result in damage.

Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■ Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than five minutes for the oil to
drain back into the bottom of the engine.
Hold a rag under the end and
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end, pull the dipstick out and check
the oil level.

■ Engine oil consumption
Some engine oil will be consumed while driving. The rate of consumption
can be affected by such factors as transmission type, driving style, terrain
and temperature. Under the followi ng conditions, oil consumption can be
increased and thus require refilling between maintenance intervals:
● When the engine is new and within the break-in period
● When the engine oil is of lower quality
● When the incorrect oil viscosity is used
● When engine braking is employed (repeatedly)
