On models without navigation systemIf your vehicle's battery is
disconnected, or goes dead, the time
is reset to 1:00. To set the time again,
follow the setting procedure (see
page 293).
If your vehicle's battery is
disconnected or goes dead, the audio
system will disable itself. The next
time you turn on the radio you will
see‘‘ENTER CODE ’’in the
frequency display. Use the preset
bars or preset buttons (depending on
the model) to enter the five-digit
code (see page 291).
On models with
navigation system
The navigation system will also
disable itself. The next time you turn
on the ignition switch, the system
will require you to enter a PIN before
it can be used. Refer to the
navigation system manual. Vehicle Storage
If you need to park your vehicle for
an extended period (more than 1
month), there are several things you
should do to prepare it for 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 fuel tank.●Wash and dry the exterior
completely.●Clean the interior. Make sure the
carpeting, floor mats, etc., are
completely dry.●Leave the parking brake off. Put
the transmission in Park.

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or
replaced, and put it back on your
vehicle as soon as you can.
Check the inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
60 psi (420 kPa , 4.2 kgf/cm
2)Follow these precautions:
●Never exceed 50 mph (80 km/h).●This tire gives a harsher ride and
less traction on some road
surfaces. Use greater caution while
driving.●Do not mount snow chains on the
compact spare tire.●Do not use your compact spare tire
on another vehicle unless it is the
same make and model.●After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
After several miles (kilometers)
driving with the spare, this
indicator begins to flash, then
stays on again. You will also see a
‘‘
CHECK TPMS SYSTEM ’’
message on the multi-information
display (see page 393).
Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed for mounting a regular tire.

The reading of the vehicle's
temperature gauge on the multi-
information display should stay in the
midrange. If it climbs to the H (Hot)
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If the coolant temperature rises to
224°F (118°C) or more, the
temperature gauge will appear on the
display and blink for several times.
At the same time, the beeper will
sound once.
If your vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to the H (Hot) mark.
Or you may see steam or spray
coming from under the hood.
Driving with the temperature gauge
reading at the H (Hot) mark can cause
serious damage to the engine.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
1. Safely pull to the side of the road. Put the transmission in Park, and
set the parking brake. Turn off all
accessories, and turn on the
hazard warning lights. 2. If you see steam and/or spray
coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If
the high heat is due to
overloading, the engine should
start to cool down almost
immediately. If it does, wait until
the temperature gauge comes
down to the midpoint, then
continue driving.
4. If the temperature gauge reading stays at the H (Hot) mark, turn off
the engine.

Low Oil Pressure Indicator
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 an ‘‘OIL PRESSURE
LOW ’’message on the multi-
information display (see page 79).
The indicator notifies you of low oil
pressure and does not measure the
oil level. Check your vehicle's oil
level at each refueling.
Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn off
the engine as soon as you can safely get
the vehicle stopped. 1. Safely pull off the road, and shut
off the engine. Turn on the hazard
warning lights.
2. Let the vehicle sit for a minute. Open the hood, and check the oil
level (see page 357). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
3. If necessary, add oil to bring the level back to the full mark on the
dipstick (see page 420).
4. 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
before you can continue driving
(see Emergency Towing on page
475). Charging System Indicator
If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
You will also see a ‘‘CHECK
CHARGING SYSTEM ’’message on
the multi-information display (see
page 79).
Immediately turn off 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 service station or garage
where you can get technical
assistance.

If the indicator comes on
while driving, it means one
of the engine's emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle's performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fuel fill cap. You will also see a
‘‘ TIGHTEN FUEL CAP ’’message on
the multi-information display.
Tighten the cap until it clicks at least
once. Tightening the cap will not turn
the indicator off immediately; it can
take several days of normal driving.
If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have your vehicle
checked by your dealer as soon as
possible.
If you keep driving with the malfunction
indicator lamp on, you can damage
your vehicle's emissions controls and
engine. Those repairs may not be
covered by your vehicle's warranties.
The indicator may also come on with
the ‘‘D ’’indicator.
You will also see a ‘‘CHECK
EMISSION SYSTEM ’’message on
the multi-information display (see
page 79).
Readiness Codes
Your vehicle has certain ‘‘readiness
codes ’’that are part of the on-board
diagnostics for 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,
these codes may be erased. It can
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 malfunction indicator lamp will
come on for 20 seconds. If it then
goes off, the readiness codes are set.
If it blinks five times, the readiness
codes are not set. If possible, do not
take your vehicle for an emissions
test until the readiness codes are set.
Refer to
Emissions Testing for
more information (see page 490).

Brake System Indicator
(Red)U.S. CanadaThe brake system indicator (red)
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 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
429).
You will also see a‘‘BRAKE FLUID
LOW ’’message on the multi-
information display (see page 79). 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
‘‘CHECK BRAKE
SYSTEM ’’message on the multi-
information display (see page 79). 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
Emergency
Towing on page 475).
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.

Brake System Indicator
(Amber)U.S. CanadaYour vehicle has an electric vacuum
pump located in the engine
compartment. It enhances the
effectiveness of your vehicle's brake
system more frequently when you
drive in cold weather or thinner air at
high altitude after the engine is
started.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come from the engine
compartment. This is normal.The brake system indicator (amber)
on the instrument panel normally
comes on when you turn the ignition
switch to the ON (II) position and
goes off after the engine starts. If it
comes on at any other time, press on
the brake pedal with your foot
several times until the indicator turns
off. If the indicator is still on or
comes on again after this procedure,
there is a problem in the brake
system including the electric vacuum
pump. If this happens, the brake
pedal might feel heavy when you
press it. Have your vehicle checked
by your dealer.
