Maintenance
Opening the Hood
1. Park the vehicle on a level surface, and set
the parking brake.
2. Pull the hood release handle under the
driver’s side lower corner of the dashboard.
u The hood will pop up slightly.
3. Push the hood latch lever (located under
the front edge of the hood to the center) to
the side and raise the hood. Once you have
raised the hood slightly, you can release the
lever.
4. Remove the support rod from the clamp
using the grip. Mount the support rod in
the hood.
When closing, remove the support rod, and
stow it in the clamp, then gently lower the
hood. Remove your hand at a height of
approximately 12 inches (30 cm) and let the
hood close.1 Opening the Hood
NOTICE
Do not open the hood when the wiper arms are
raised. The hood will strike the wipers, resulting in
possible damage to the hood and/or the wipers.
NOTICE
Do not press the engine cover forcibly. This may
damage the engine cover and component parts.
When closing the hood, check that the hood is
securely latched.
If the hood latch lever moves stiffly, or if you can
open the hood without lifti ng the lever, the latch
mechanism should be cl eaned and lubricated.
Do not open the hood while the Auto Idle Stop
function is activated.
3WARNING
The hood support rod can become very hot
due to heat fr om the engine.
To ensure against po ssible burns, do not
handle the metal section of the rod: Use
the foam grip instead.

install a new oil filter.
u Apply a light coat of new engine oil to
the filter gasket.
8. Put a new washer on the drain bolt, then
reinstall the drain bolt.

Jump Starting Procedure
Turn off the power to electric devices, such as audio and lights. Turn off the engine,
then open the hood. 1.Open the cover on the positive + terminal.
2. Connect the first jump er cable to your
vehicle’s battery + terminal.
3. Connect the other end of the first jumper
cable to the booster battery + terminal.
u Use a 12-volt booster battery only.
u When using an automotive battery
charger to boost your 12-volt battery,
select a lower charging voltage than 15-
volt. Check the charger manual for the
proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.1If the Battery Is Dead
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Be careful
not to tangle the jumper cables or allow the cable
ends to touch each other while attaching or
detaching the jumper cables.
3WARNING
A battery can explode if you do not follow
the correct procedure, seriously injuring
anyone nearby.
Keep all sparks, open flames, and smoking
materials away from the battery.

uuIndicator, Coming On/Blinking uIf the Brake System Indicator (Red) Comes On or Blinks
Handling the Unexpected
If the Brake System Indicator (Red) Comes On or
Blinks
■Reasons for the indicator to come on
• The brake fluid is low.
• There is a malfunction in the brake system.
■What to do when the indicator comes on while driving
Depress the brake pedal lightly to check pedal pressure.
• If normal, check the brake fluid level the next time you stop.
• If abnormal, take immediate action. If necessary, downshift the
transmission to slow the vehicle using engine braking.
■Reasons for the in dicator to blink
There is a problem with the electric parking brake system.
■What to do when the indicator blinks
Avoid using the parking brake and have your vehicle checked by a dealer
immediately.
1 If the Brake System Indicator (Red) Comes On or Blinks
Have your vehicle re paired immediately.
It is dangerous to drive with low brake fluid. If there
is no resistance from the brake pedal, stop
immediately in a safe plac e. If necessary downshift
the gears.
If the brake system indicator (red) and ABS indicator
come on simultaneously , the electronic brake
distribution system is not wo rking. This can result in
vehicle instability under sudden braking.
Have your vehicle inspecte d by a dealer immediately.
If the brake system indicator (red) blinks at the same
time when the brake system indicator (amber) comes
on, the parking br ake may not work.
Avoid using the parking brak e and have your vehicle
checked by a dealer immediately. 2 If the Brake System Indicator (Red) Comes

dealer.1Inspecting and Changing Fuses
NOTICE
Replacing a fuse with on e that has a higher rating
greatly increases the chances of damaging the
electrical system.
Use the charts to locate the fuse in question and
confirm the specified amperage on the fuse label. 2 Fuse Locations P. 664
Replace fuse with a spare fuse of the same specified
amperage.

Emissions Testing
Testing of Readiness Codes
Your vehicle has readiness code as part of the onboard self diagnostic system.
Some states use these codes for testing to verify whether your vehicle’s emissions
components are working properly.
The codes may not be read properly if testing is performed just after the battery has
gone dead or been disconnected.
To check if they are set, set the power mo de to ON, without starting the engine. The
malfunction indicator lamp will come on for several seconds. If it then goes off, the
readiness codes are set. If it blinks fi ve times, the readiness codes are not set.
If you are required to have your vehicle te sted before the readiness codes are ready,
prepare the vehicle for retest ing by doing the following:
1. Fill the gas tank to approximately 3/4 full.
2. Park the vehicle and leave the engine off for 6 hours or more.
3. Make sure the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4. Start the engine without touching the ac celerator pedal, and let it idle for 20
seconds.
5. Keep the vehicle in
(P. Increase the engine speed to 2,000 rpm, and hold it there
for about 3 minutes.
6. Let the engine idle with your foot off the accelerator for 20 seconds.
7. Select a nearby, lightly traveled major hi ghway where you can maintain a speed
of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the highway in
(D. Do not use cruise control. When traffi c allows, drive for 90 seconds without
moving the accelerator pedal. (V ehicle speed may vary slightly; this is okay.) If you
cannot do this for a continuous 90 seconds because of traffic conditions, drive for
at least 30 seconds, then repeat it two more times (for a total of 90 seconds).
1Testing of Readiness Codes
The readiness codes are erased when the battery is
disconnected, and set again onl y after several days of
driving under a variety of conditions.
If a testing facility determines that the readiness
codes are not set, you may be requested to return at
a later date to complete the test.
If the testing facility determines the readiness codes
are still not set, see a dealer.
