NOTE
The fresh water reservoir may be equipped with
an optional thermal valve which is set to open
at about 35°F, thereby automatically draining
the reservoir in near-freezing temperatures.
Cleaning Cabinet
A hose connection and valve is located behind a
small door in the top curbside corner of the rear
lavatory wall. It can be used to attach a garden
hose for lavatory cleaning. To use, connect a
fresh water supply to the connection in the engine
compartment, identified as "Cleaning Kit", located
next to the fresh water reservoir fill coupling.
To prevent freezing during cold weather, drain
the hose after every use.

FLUID LEVEL VERIFICATION

Periodic inspection of oil and fluids levels is the
most economical and easiest way to help your
vehicle perform at its best. Rigorous oil level
inspection and replacement will greatly help
minimize expensive and unscheduled repairs.

ENGINE OIL LEVEL

WARNING
Check the engine oil level with vehicle parked on
a level surface and with the parking brake
engaged.
Check engine oil level when engine is still warm.
Shut off engine and wait at least 10 minutes for oil
to drain into oil pan before checking. Check
engine oil level daily or before each trip. Add oil
as required. Do not overfill. Remove dipstick,
wipe clean and fully reinsert to ensure an
accurate reading. Remove dipstick and check
engine oil level.
Do not let the oil level fall below the marking on
the dipstick. Do not overfill so the level is above
the upper marking on the dipstick. Add oil through
the oil filler pipe as required in order to maintain
level within the safe range.
