2.Connect the other end of the first jumper
cable to the assisting vehicle’s + terminal.
uUse a 12-volt booster battery only.
3.Connect the second jumper cable to the
assisting vehicle’s - terminal.
4.Connect the other end of the second
jumper cable to the grounding strap as
shown.
Do not connect this jumper cable to any
other part.
5.If your vehicle is connected to another
vehicle, start the assisting vehicle’s engine
and increase its rpm slightly.
6.Attempt to start your vehicle’s engine. If it
turns over slowly, check that the jumper
cables have good metal-to-metal contact.

Jump Starting Procedure
1Jump Starting
Securely attach the jumper cables clips so that they
do not come off when the engine vibrates. Also be
careful not to tangle the jumper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
Battery performance degrades in cold conditions and
may prevent the engine from starting.

WARNING
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.

■
Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the high temperature
indicator goes off.
uIf 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.
uIf the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
uIf 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 sufficiently, restart it and check the high temperature
indicator.
If the high temperature indicator is off, resume driving. If it stays on, contact a dealer
for repairs.
1How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/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.

Handling the Unexpected
If the Malfunction Indicator Lamp Comes On or Blinks
■
Reasons for indicator lamp to come on or blink
•Comes on when there is a problem with the engine emissions control
system, or the fuel fill cap is missing, or loose.
•Blinks when engine misfiring is detected.
■
What to do when the indicator lamp comes on
Avoid high speeds and immediately get your vehicle inspected at a
dealer.
■
What to do when the indicator lamp blinks
Park the vehicle in a safe place with no flammable items and wait at least
ten minutes or more with the engine stopped until it cools.
■
The message appears on when:
An evaporative system leak is detected. This may be caused by the fuel fill cap being
loose or not being installed.
■
What to do when the message appears:
1.Stop the engine.
2.Check that the fuel fill cap is fully installed.
uIf not, loosen the cap, and then retighten it until it clicks at least once.
3.Drive for several days of normal driving.
uThe message should go off.
■
When the malfunction indicator lamp comes on
Malfunction indicator lamp comes on if the system continues to detect a leak of
gasoline vapor. If this happens, check the fuel fill cap using the procedures described
above.

1If the Malfunction Indicator Lamp Comes On or Blinks
NOTICEIf you drive with the malfunction indicator lamp on,
the emissions control system and the engine could be
damaged.
If the malfunction indicator lamp blinks again when
restarting the engine, drive to the nearest dealer at
31 mph (50 km/h) or less. Have your vehicle
inspected.

Handling the Unexpected
If the Brake System Indicator 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 EPS Indicator Comes On
■
Reasons for the indicator to come on
•Comes on when there is a problem with EPS.
•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
Stop the vehicle in a safe place and restart the engine.
If the indicator comes on and stays on, immediately have your vehicle
inspected by a dealer.
1If the Brake System Indicator Comes On
Have your vehicle repaired immediately.
It is dangerous to drive with low brake fluid. If there
is no resistance from the brake pedal, stop
immediately in a safe place. If necessary downshift
the gears.
If the brake system indicator and ABS indicator come
on simultaneously, the electronic brake distribution
system is not working. This can result in vehicle
instability under sudden braking.
Have your vehicle inspected by a dealer immediately.

1If the EPS Indicator Comes On
NOTICEIf you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel on
the full left or right position for a while, the system
heats up. The system goes into a protective mode,
and limits its performance. The steering wheel
becomes harder and harder to operate. Once the
system cools down, EPS is restored. Repeated
operation under these conditions can eventually
damage the system.

. Turn
headlights and all accessories off.
2.Check the fuses in the engine
compartment.
uIf the fuse is blown, have it replaced by a
dealer.
3.Inspect the small fuses in the engine
compartment and the vehicle interior.
uIf there is a burned out fuse, remove it
with the fuse puller and replace it with a
new one.
1Inspecting and Changing Fuses
NOTICEReplacing 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. 260 and P. 261.
There is a fuse puller on the back of the engine
compartment fuse box cover.

Information
Emissions TestingTesting of Readiness CodesYour vehicle uses “readiness codes,” as part of its onboard self diagnostic system.
Some states refer to these codes during testing to see if your vehicle’s emissions
components are working properly.
The codes may not be read if you go through the testing just after the battery has
gone dead or been disconnected.
To check if they are set, turn the ignition switch to ON
(w
, 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 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 accelerator pedal, and let it idle for 20
seconds.
5.Keep the vehicle in
(P
(automatic transmission) or
(N
(manual transmission).
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.
1Testing 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 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.
