If the vehicle is f acing downhill,
turn the front wheels toward the
curb.
If the vehicle is f acing uphill, turn
the front wheels away from the

Check the condition of the battery
monthlybylookingatthetest
indicator window. The label on the
battery explains the test indicator’s
colors. Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Check the terminals f or corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it of f with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
f uture corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualif ied technician. If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.
To see the label, remove the battery

Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
If you need to park your vehicle f or
an extended period (more than 1
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.
Fill the f uel tank.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.
Leave the parking brake off. Put
the transmission in Park. Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door

Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(see on page). Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a dealer or a service station
where you can get technical
assistance.
Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning lights.
This indicator should never come on
when the engine is running. If it
starts flashing or stays on, or if you
see a ‘‘CHECK ENGINE OIL
LEVEL’’ message on the multi-
inf ormation display, the oil pressure
has dropped very low or lost
pressure. Serious engine damage is
possible, and you should take
immediate action. If the charging system indicator
comes on brightly when the engine
is running, or if you see a ‘‘CHECK
CHARGING SYSTEM’’ message on
the multi-information display, the
battery is not being charged.
