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 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 sufficiently, re start it and check the temperature gauge.
If the temperature 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 emergen cy/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
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.

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 Low Tire Pressure Indicator Comes On
■Reasons for the indicator to come on
A tire pressure is significantly low. If the compact spare tire is installed,
the indicator stays on for a while, then goes off after driving a few miles
(kilometers).
■What to do when the indicator comes on

Information
Emissions Testing
Testing of Readiness Codes
Your 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, 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 te sted 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 en gine off for 6 hours or more.
3. Make sure the ambient temperature is be tween 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. 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.
