Always change the oil and f ilter
according to the maintenance
messages shown on the inf ormation
display or multi-inf ormation display
(depending on models). The oil and
f ilter collect contaminants that can
damage your engine if they are not
removed regularly.Run the engine until it reaches
normal operating temperature,
then shut it off.
Open the hood, and remove the
engine oil f ill cap. Remove the oil
drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.Remove the oil f ilter, and let the
remaining oil drain. A special
wrench (available from your
dealer) is required.
Install a new oil f ilter according to
the instructions that come with it. Check the oil f ilter to make sure
its gasket did not stick to the f ilter
base. A stuck gasket could cause
an oil leak.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
technician. 1.

f rom the transmission, and wipe it
with a clean cloth.
If you are not sure how to add f luid
or you do not have the proper

maintenance done by a skilled
technician.
Park the vehicle on level ground.
Start the engine until the radiator

Turn of f the engine. For accurate
results, wait at least 60 seconds,
andnomorethan90seconds,
af ter turning of f the engine to
check the f luid level.
Check the f luid level with the engine
at normal operating temperature.
Insert the dipstick all the way into
the transmission securely as
shown in the illustration.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower

Your vehicle is equipped with a
intercooler on the engine to cool the
air f low f rom a turbo charger into
the engine. The intercooler f ins bend
easily. Do not push them with your
f inger.Have your dealer replace the filter
when this service is indicated by a
maintenance message on the
inf ormation display or multi-
inf ormation display (depending on
the models). It should be replaced
every 15,000 miles (24,000 km) if you
drive primarily in urban areas that
have high concentrations of soot in
the air, or if the flow from the
heating and cooling system becomes
less than usual. This f ilter removes the dust and

Clean the wheels as you would the
rest of the exterior. Wash them with
thesamesolution,andrinsethem
thoroughly.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum from corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stiff
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a soft brush or sponge. To
safely operate your vehicle, your
ti res must be the proper type and
size, in good condition with adequate
tread, and correctly inflated.
The following pages give more
detailed information on how to take
care of your tires and what to do
when they need to be replaced. Keeping
the tires properly inflated
provides the best combination of
handling, tread life, and riding
comfort.
Underinflated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinflated tires can make your
vehicleridemoreharshly,are
more prone to damage from road
hazards, and wear unevenly.

(TPMS)willwarnyouwhenatire
pressure is low. See page f or

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this
owner’s manual regarding tire
inflation and maintenance.

Every time you check inf lation, you
should also examine the tires f or
damage, f oreign objects, and wear.
Youshouldlookfor:Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherof theseconditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord.
Excessive tread wear. Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a
band 1/2 inch (12.7 mm) wide band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
lef t on the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators. In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
Have your dealer check the tires if
you f eel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed f rom the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comf ort and tire lif e. For best results,
have the installer perform a dynamic
balance.

To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the inf ormation display or multi-
inf ormation display (depending on
models). Move the tires to the
positions shown in the diagram each
time they are rotated. If you
purchase directional tires, rotate
only f ront-to-back.Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire’s sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
TheABSworksbycomparingthe
speed of the wheels. When replacing
tires, use the same size originally
supplied with the vehicle. Tire size
and construction can affect wheel
speed and may cause the system to
activate.
It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.
If you ever replace a wheel, make
sure the new one matches the
specif ications of the original.
Replacement wheels are available at
your dealer.

If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehic le’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.Battery

contain lead and lead compounds.
If
additional battery maintenance is
needed, see your dealer or a

Check
the terminals for 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 off with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
future corrosion.
If your vehicle’s battery is

Each tire, including the spare (if
provided), should be checked
monthly when cold and inf lated to
the inf lation pressure recommended
by the vehicle manuf acturer on the
vehicle placard or tire inf lation
pressure label.
(If your vehicle has tires of a
dif f erent size than the size indicated
on the vehicle placard or tire
inf lation pressure label, you should
determine the proper tire inf lation
pressure f or those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale
when one or more of your tires is
signif icantly under-inf lated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inf late them to
the proper pressure.Driving on a signif icantly
underinf lated tire causes the tire to
overheat and can lead to tire failure.
Underinf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if under-inf lation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
