5. Pull it out again and examine the level.The level is normal if it is between the
MIN and MAX marks.
If it is near or below MIN, add enough
oil to bring the level to MAX.
CAUTION
Do not overfill the engine oil. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully.
Engine Coolant
▼ Inspecting Coolant Level
WA R N I N G
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the engine has
been running, parts of the engine
compartment can become very hot. You
could be burned. Carefully inspect the
engine coolant in the coolant reservoir, but
do not open it.
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.

Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
The top of the float should be between F
and E.

Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.
Body Lubrication
▼Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should be
lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.

Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.

▼Aluminum Wheel Maintenance*
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
CAUTION
Do not use any detergent other than mild
detergent. Before using any detergent,
verify the ingredients. Otherwise, the
product could discolor or stain the
aluminum wheels.
NOTE
Do not use a wire brush or any abrasive
cleaner, polishing compound, or solvent
on aluminum wheels. They may damage
the coating.
Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thoroughly with
lukewarm or cold water. Also, be sure to
clean the wheels after driving on dusty
or salted roads to help prevent
corrosion.
Avoid washing your vehicle in an
automatic car wash th
at uses high-speed
or hard brushes.
▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use g
asoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts s uch as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately.
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result in
deformation of plastic parts or paint
damage.
