i-stop*
The i-stop function automatically stops the engine when the vehicle is stopped at a traffic
light or stuck in traffic, and then restarts the engine automatically to resume driving. The
system provides improved fuel economy, reduced exhaust gas emis sions, and eliminates
idling noise while the engine is stopped.

•The i-stop indicator light (green) turn s on under the following conditions:
•When engine idling is stopped.
•Engine idling stop conditions are met while the vehicle is being driven.
•The i-stop indicator light (green) turns off when the engine is restarted.

If the selector lever is shifted from D or M (not in second gear fixed mode) position to N or
P position while engine idling is stopped, the engine does not restart even when the brake
pedal is released. The engine will restart if the brake pedal is depressed again or the
selector lever is shifted to the D, M (not in second gear fixed mode), or R position. (For the
purposes of safety, always keep the brake pedal depressed when shifting the selector lever
while engine idling is stopped.)

position, and the driver's seat belt is unfastened and the driver's door is opened, the engine
restarts.

▼Vehicle Roll Prevention Function (Automatic transaxle)
Vehicles with the i-stop function are equipped with a vehicle r
oll prevention function. This
function prevents the vehicle fr om rolling, such as when releas ing the brake pedal while on
a slope under the following conditions:
•While engine idling is stopped (prevents the vehicle from rolling back)
•When the engine restarts after re leasing the brake pedal (prevents the vehicle's sudden
movement due to vehicle creep), sudden movement of the vehicle is prevented by
controlling the brakes.

WA R N I N G
Do not rely completely on the vehicle roll prevention function.
The vehicle roll prevention function is a supplementary function which operates for a
maximum of four seconds after releasing the brake pedal and accelerating the vehicle from
an engine idling stop condition. Over relian ce on the system may result in an unexpected
accident if the vehicle were to suddenly acce lerate. Before starting to drive the vehicle,
always confirm the safety of the surroundings and operate the selector lever, brake pedal,
and accelerator pedal appropriately. Note th at the vehicle may move suddenly depending
on the vehicle's load or if it is towing something.

Note that the vehicle may move suddenly af ter the vehicle roll prevention function is
released while the vehicle is un der the following conditions:
The selector lever is in the N position.
If the selector lever is shifted to the N position and the brake pedal is released while the
i-stop function is operating, the brake force is gradually released. To accelerate the
vehicle, release the brake pedal after the engi ne restarts and shift the selector lever to a
position other than the N position.
NOTE
•When the vehicle is stopped on a steep grade, the vehicle roll prevention function does not
operate because engine idling is not stopped.
•The brake pedal response may change, sound may occur from the brakes, or the brake
pedal could vibrate from the operation of the vehicle roll prevention function. However,
this does not indicate a malfunction.
▼ i-stop Warning Light (Amber)/i
-stop Indicator Light (Green)
To ensure safe and comfortable use of the vehicle, the i-stop s ystem constantly monitors the
driver's operations, the vehicle's interior and exterior enviro nment, and the operational status
of the vehicle, and uses the i-stop warning light (amber) and i -stop indicator light (green) to
inform the driver o f various cautions and warnings.
NOTE
On vehicles equipped with the centre display, the i-stop operation status is displayed in the
fuel monitor contro l status display.
