Auto Idle Stop
To help maximize fuel economy, the engine automatically stops when the vehicle
comes to a stop, depending on environmental and vehicle operating conditions. The
AUTO STOP indicator blinks at this time. The engine then restarts once the vehicle is
about to move again when you depress the clutch pedal fully, and the indicator goes
off.
If the driver’s door is opened while the
indicator is blinking, a buzzer sounds to notify
you that the Auto Idle Stop function is in operation.

Handling the Unexpected
■ 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 co oled 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 emerge ncy/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.MAX
