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.

Safety When Performing Maintenance
Some of the most important safety precautions are given here.
However, we cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not you should perform
a given task. • To reduce the possibility of fire or explosion, keep cigarettes, sparks, and flames
away from the battery and all fuel related parts.
• To clean parts, use a commercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the 12 volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
uOnly operate the engine if there is sufficient ventilation.
• The vehicle must be in a stationary condition.
uMake sure your vehicle is parked on level ground, the parking brake is set, and
the engine is off.
• Be aware that hot parts can burn you.
uMake sure to let the engine and exhau st system cool thoroughly before
touching vehicle parts.
• Be aware that moving parts can injure you.
uDo not start the engine unless instructed, and keep your hands and limbs away from moving parts.

Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Promptly wipe it away using a soft cloth and clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterio ration caused by salt and other road
contaminants. Use a sponge and mild de tergent to wipe away promptly.
Be careful not to use harsh chemicals (including some commercial wheel cleaners) or
a stiff brush. They can damage the clear coat of the aluminum alloy wheels that
helps keep the aluminum from corroding and tarnishing.

NOTICE
Chemical solvents and strong cleaners can damage
the paint, metal, and plastic on your vehicle. Wipe up
spills immediately.
1Maintaining the Bumpers and Other Resin Coated Parts
Ask a dealer about the correct coating material when
you want to repair the painted surface of the parts made of resin.
1Cleaning the Window
Wires are mounted to the inside of the rear window.
Wipe along the same direction as the wires with a
soft cloth so as not to damage them.
