Jump StartingTurn off the power to electric devices, such as audio and lights. Turn off the engine,
then open the hood.1.Connect the first jumper cable to your
vehicle's battery + terminal.
2. 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.
3. Connect the second jumper cable to the
booster battery - terminal.■
Jump Starting Procedure
1Jump Starting
Securely attach the jumper cables clips so that they

uuOverheating uHow to Handle Overheating
Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle comes down.
u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
u If the coolant level in the engine coolant
reserve tank is low, add coolant until it
reaches the MAX mark.
u If there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.■Last thing to do
Once the engine has cooled sufficien tly, restart it and check the temperature gauge.
If the temperature gauge needle has gone down, resume driving. If it has not gone
down, contact a dealer for repairs.
1 How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emerge ncy/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.

WARNING
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 removing the radiator cap.

If the Brake System Indicator (Red) Comes On
■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
Press 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.
If the Electric Power Steering (EPS) System Indicator Comes On
■Reasons for the indicator to come on
• Comes on if there is a problem with the EPS system.
• If you depress the accelerator pedal repeatedly to increase the engine
speed while the engine is idling, the indicator comes on, and
sometimes the steering wheel becomes harder to operate.■What to do when the indicator comes on

*1. Turn
headlights and all accessories off.
2. Remove the fuse box cover.
3. Check the large fuse in the engine
compartment.
u If the fuse is blown, use a Phillips-head
screwdriver to remove the screw and
replace it with a new one.
4. Inspect the small fuses in the engine
compartment and the vehicle interior.
u If there is a burned out fuse, remove it
with the fuse puller and replace it with a
new one.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of
an ignition switch.
1 Inspecting and Changing FusesNOTICEReplacing a fuse with one that has a higher rating
greatly increases the chances of damaging the
electrical system.
Replace fuse with a spare fuse of the same specified
amperage.
Confirm the specified amperage using the charts on
P. 524 to 525.
There is a fuse puller on the back of the engine

Information
Emissions TestingTesting of Readiness CodesYour vehicle has “Readiness Codes,” as part of the onboard self diagnostic system.
Some States use these codes as a test to see if 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, turn the ignition switch to ON
(w
*1, 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 five times, the readiness codes are
not set.
If you are required to have your vehicle tested before the readiness codes are ready,
prepare the vehicle for retesting by doing the following:
1. Fill the gas tank to approximately 3/4 full.
2. Park the vehicle and leave the engine off for six 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 accelerator pedal, and let it idle for 20
seconds.
5. Keep the vehicle in
(P
(automatic transmission/CVT) or
(N
(manual
transmission). Increase the engine speed to 2,000 rpm, and hold it there for about
three minutes.
6. Let the engine idle with your foot off the accelerator for 20 seconds.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
1 Testing of Readiness Codes
The readiness codes are erased when the battery is
disconnected, and set again only after several days of
driving under a variety of conditions.
If a testing facility dete rmines that the readiness
codes are not set, you may be requested to return at
a later date to complete the test.
If the testing faci lity determines the readiness codes
are still not set, see a dealer.
