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.

1Auto Idle Stop
If the Auto Idle Stop operating time lasts long enough
to lower the 12 volt battery charge or the IMA battery charge, the engine may not restart automatically.
Manually turn off the engine when you leave your
vehicle.
The duration of Auto Idle Stop operation:• Increases in the ECON mode, compared to normal
or sport mode, with climate control in use.
• Decreases if you operate the wipers and climate
control simultaneously.

uuChecking and Maintaining TiresuDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
DOT Tire Quality Grading (U.S. Vehicles) The tires on your vehicle meet all U.S. Federal Safety Requirements. All tires are also graded for treadwear, traction,
and temperature performance according to Department of
Transportation (DOT) standards. The following explains these gradings. Quality grades can be found where applicable on the tire sidewall
between tread shoulder and maxi mum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

Maintenance
Climate Control System Maintenance
Dust and Pollen Filter
The Climate Control system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM
messages will let
you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1Dust and Pollen Filter
If the airflow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

uuIndicator, Coming On/BlinkinguIf the Charging System Indicator Comes On
Handling the Unexpected
If the Charging System Indicator Comes On■Reasons for the indicator to come on
Comes on when the 12 volt battery is not being charged. ■ What to do when the indicator comes on
Turn off the climate control system, rear defogger, and other electrical
systems, and immediately contact a dealer for repairs.
1If the Charging System Indicator Comes On If you need to stop temporarily, do not turn off the
engine. Restarting the engine may rapidly discharge
the 12 volt battery.
This indicator may also come on when the Auto Idle
Stop function is activated for a while. Restart the
engine. 2 Auto Idle Stop P. 228
This indicator may also come on when the IMA
battery charge drops below a desired level.
The engine starts to recharge the battery. 2 Auto Idle Stop P. 225
The indicator goes off when the battery is being
charged normally.
This indicator may blink after starting when the
outside temperature is below -20°F (-30°C). It will stop blinking after the IMA battery warms up.
