Jump Starting
Turn off the power to electric devices, such as the audio and lights. Turn off the
engine, then open the hood. 1.Open the terminal cover on your vehicle’s
battery positive + terminal.
2. Connect the first jumper 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-volts. Check the charger manual for
the proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.
■Jump Starting Procedure1Jump Starting
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Also be
careful not to tangle the ju mper 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 engi ne from starting.
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.

(as shown). Do not connect this jumper
cable to any other part.
6. If your vehicle is connected to another
vehicle, start the assisting vehicle's engine
and increase its rpm slightly.
7. Attempt to start your vehicle's engine. If it
turns over slowly, check that the jumper
cables have good metal-to-metal contact.

terminal.
3. Disconnect the jumper cable from your vehicle's battery + terminal.
4. Disconnect the other end of the jumper cable from the booster battery +
terminal.
Have your vehicle inspected by a n earby service station or a dealer.

■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle goes down.
u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level, an d check the cooling
system components for leaks.
u If the coolant level, in the reserve tank is
low, or no coolant in the tank, check that
the radiator is cool . Cover the reserve
tank cap with a hea vy cloth and open the
cap. Add coolant until it reaches the
MAX mark and put the cap back on.
■Last thing to do
Once the engine has cooled sufficiently , restart it, and check the temperature
gauge.
If the temperature gauge needle has gone do wn, 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 emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
Removing the reserve tank 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 reserve tank
cap.

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 acti on. If necessary, downshift the
transmission to slow the vehicle using engine braking.
■Reason for the indicator 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 and ABS indicator come
on simultaneously, the elec tronic brake distribution
system is not working. Th is 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.

Information
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, tu rn the ignition switch to ON
(w*1, without starting the
engine. The malfunction indicator lamp will co me 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 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.
*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 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.
