The transmission should be drained
and ref illed with new f luid when this
service is shown on the inf ormation
display or multi-inf ormation display
(depending on models).Remove the dipstick (yellow loop)
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
equipment to reach the transmission
f luid f ill hole, you should have this
maintenance done by a skilled
technician.
Park the vehicle on level ground.
Start the engine until the radiator
f an comes on and rotate it once.
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

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
pollenthatisbroughtinfromthe
outside through the heating and
cooling system.

Your vehicle is equipped with an
antenna at the rear of the roof . Bef ore
using a ‘‘drive-through’’ car wash,
remove the antenna by unscrewing it by
hand. This prevents the antenna f rom
being damaged by the car wash brushes. Do not spray water (f rom such sources
as garden hoses, high pressure
sprayers) into the engine compartment.
It may cause serious damage to your
vehicle, and could also damage the
intercooler f ins.

Let the vehicle sit for a minute.
Op en 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
the charging system
indicator comes on brightly
wh en the engine is running, the
battery is not being charged.
Safely
pull off the road, and shut
off 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, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
befo re you can continue driving
(see on page
). You
will also see a ‘‘CHECK
CHARGI NG SYSTEM’’ message on
the multi-information display (see
page ).
Immediately turn off all electri cal
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 service station or garage
where you can get technical
assistance.
If
necessary, add oil to bring the
level back to the full mark on the
dipsti ck (see page ).
You
will also see an ‘‘OIL
PRESSURE LOW’’ message on the
multi-info rmation display (see page
). 1.

The brake system indicator (red)
normallycomesonwhenyouturn
the ignition switch to the ON (II)
position, and as a reminder to check
the parking brake. It will stay on if
you do not fully release the parking
brake.
If the brake system indicator (red)
comes on while driving, the brake
fluid level is probably low. Press
lightly on the brake pedal to see if it
feels normal. If it does, check the
brake fluid level the next time you
stop at a service station (see page
). If
the fluid level is low, take your
vehicle to a dealer, and have the
brake system inspected for leaks or
worn brake pads.
However, if the brake pedal does not
feel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit
design will still give you braking at
two wheels. You will feel the brake
pedal go down much farther before
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
You will also see a ‘‘BRAKE FLUID
LOW’’ message on the multi-
info rmation display (see page ).You
will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
info rmation display (see page ).Slow
down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (see on page ).

Any other method of towing will
damage the drive system. When you
contact the towing agency, inf orm

call a prof essional towing service or

with just a rope or chain. It is very
dangerous.
The only way you can saf ely tow

The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
Quality grades can be f ound where
applicable on the tire sidewall
between the tread shoulder and the
maximum section width. For
example: The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices, and dif f erences in
road characteristics and climate.The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.
