´´ µStart the vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.
The numbers in the illustration
show you the order to connect the
jumper cables.
Connect one jumper cable to the
positive ( ) terminal on your
battery. Connect the other end to
the positive ( ) terminal on the
booster battery. Once the vehicle is running,
disconnect the negative cable f rom
your vehicle, then f rom the
booster battery. Disconnect the
positive cable f rom your vehicle,
and then from the booster battery.
Install the battery terminal cover.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until everything is
disconnected. Otherwise, you may
cause an electrical short.
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding point
as shown. Do not connect this
jumper cable to any other part of
the engine.

If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(seeon
page ).
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.
Start the engine, and set the
temperature to maximum heat
(climate control to 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.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.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before

Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
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).
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.
Go to a service station or garage
where you can get technical
assistance.
You will also see a ‘‘CHECK
CHARGING SYSTEM’’ message on
the multi-information display (see
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.
If the charging system indicator
comes on brightly when the engine
is running, the battery is not being
charged.
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.
You will also see a ‘‘CHECK
ENGINE OIL LEVEL’’ message on
the multi-information display when
this indicator comes on. 1.

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 this indicator comes on
while driving, 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 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. 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 the battery in your vehicle has
been disconnected or gone dead,
thesecodesmaybeerased.Ittakes
several days of driving under various
conditions to set the codes again.
You will also see a ‘‘CHECK
EMISSION SYSTEM’’ message on
the multi-information display (see
page ).
If your vehicle has an automatic
transmission, the malf unction
indicator lamp may also come on
with the ‘‘D’’ indicator.

If you keep driving with the

damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

ÎIf the f luid level is low, take your
vehicle to a dealer, and have the
brake system inspected f or leaks or
worn brake pads.
However, if the brake pedal does not
f eel 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 f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down, and
you will have to press harder on the
pedal. You will also see a ‘‘LOW BRAKE
FLUID’’ message on the multi-
inf ormation display.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display when this
indicator comes on.
To check if they are set, turn the
ignition switch to the ON (II)
position (set ON mode on models
with keyless access system), 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. Ref er to
for more
inf ormation (see page ). Models equipped with the
keyless access system have an
engine start/stop button instead
of an ignition switch. ON Mode
is the equivalent of ON (II). For
more inf ormation, see pages
and .
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. Press lightly on the
brake pedal to see if it f eels normal.
If it does, check the brake f luid level
thenexttimeyoustopataservice
station (see page ). The brake system indicator normally
comes on when you turn 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
f ully release the parking brake.

Also check the combined f use box in
the under-hood f use box.
If something electrical in your
vehicle stops working, the first thing
youshouldcheckforisablownfuse.
Determine f rom the chart on pages
, and , or the diagram on
thefuseboxlidorthefuselabel,
which f use or f uses control that
component. Check those f uses f irst,
but check all the f uses bef ore
deciding that a blown f use is not the
cause. Replace any blown f uses and
check if the device works.
Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are of f . Check each of the large f uses in
the under-hood f use box by
looking at the wire inside.
Removing these f uses requires a
Phillips-head screwdriver. Remove the cover f rom the f use
box.
Models equipped with the keyless
access system have an engine
start/stop button instead of an
ignition switch. VEHICLE OFF
(LOCK) Mode is the equivalent of
LOCK (0). See page for
ignition switch and power mode
