If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Start the engine, and set the
interior temperature to maximum
(climate control to FULL AUTO at
‘‘ ’’). Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.

Always let the engine and
radiator cool down before
removing the radiator cap.

You can still drive your vehicle even
if this message appears on the multi-
inf ormation display, however you
should check the temperature gauge
while driving.
If you notice the temperature gauge
climbing to or above the red mark,
saf ely pull to the side of the road.
Follow the instructions on pagesand .
If there is a problem with the
radiator system, you will see a
‘‘CHECK RADIATOR SYSTEM’’ on
the multi-information display.
If you see this message, the engine
has probably overheated. You should
take your vehicle to a dealer, and
have it repaired as soon as possible. 503504

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.

Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If this indicator comes on
while driving, or if you see
a ‘‘CHECK EMISSION
SYSTEM’’ message on the multi-
inf ormation display, it means one of
the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. If the indicator comes on repeatedly,
even though it may go of f as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. You will also see a
‘‘TIGHTEN FUEL CAP’’ message on
the multi-information display.
Tighten the cap until it clicks at least
once (see page ). Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving. If the battery in your vehicle has
been disconnected or gone dead,
thesecodesmaybeerased.Itcan
take several days of driving under
various conditions to set the codes
again.
To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle f or an emissions
test until the readiness codes are set.

Your vehicle has several identif ying
numbers in various places.
The vehicle identif ication number
(VIN) is the 17-digit number your
dealer uses to register your vehicle
f or warranty purposes. It is also
necessary f or licensing and insuring
your vehicle. The easiest place to
find the VIN is on a plate fastened to
the top of the dashboard. You can
seeitbylookingthroughthe
windshield on the driver’s side. It is
also on the certification label
attached to the driver’s doorjamb,
and is stamped on the engine
compartment bulkhead. The VIN is
also provided in bar code on the
certif ication label.
