near hot engine or exhaust sys-

tem parts.

7-17. Auto Start Stop system

If you release the brake pedal with the

select lever kept in the “D” position, the

engine will be automatically restarted.

However, when the Auto Vehicle Hold ON

indicator light illuminates, the engine will

not restart.

Be sure to stop the engine if you

take a nap in the vehicle. If engine

exhaust gas enters the passen-

ger compartment, occupants in

the vehicle could die from carbon

monoxide (CO) contained in the

exhaust gas.

The Auto Start Stop system is designed to

automatically stop and restart the engine

when the vehicle is stationary for a short

period of time (while waiting for a traffic

light or in a traffic jam) after the engine has

warmed up. The system operates in order

to reduce fuel consumption, exhaust emis-

sions and undesired idling noise.

CAUTION

& System operation

If your vehicle has a bumper

under guard (optional), pay atten-

tion to blocks and other obstruc-

tions on the ground when park-

ing. The underspoiler could be

damaged by contact with them.

CAUTION

The Auto Start Stop system is de-

signed to automatically stop and

restart the engine for a short period

of time during idling. Do not use the

system when parking the vehicle

normally.

The braking power of the parking

brake may not be sufficient when

stronger braking power is

needed (e.g., when parking on a

steep slope while towing a trai-

ler).

Auto Start Stop indicator light (green)

If the engine is temporarily stopped by the

system, the Auto Start Stop indicator light

(green) on the combination meter will

illuminate in green. This indicator light will

turn off when the system restarts the

engine.

So that it can be used safely and comfor-

tably, in addition to driver operations, the

Auto Start Stop system is designed to

constantly monitor the vehicle conditions

as well as the environment inside and

outside the vehicle, in order to control

stopping and restarting of the engine.

vehicle is left idling without being
