The Stop & Start system protection fea-
■
ture
●
When an excessively loud sound is being
projected by the audio system, the audio
system may be automatically cut off in
order to maintain power for the Stop &
Start system function. If it occurs, turn the
engine switch off, wait for 3 seconds or
longer and then turn it to ACCESSORY
mode or IGNITION ON mode to re-
enable the audio system.
The audio system may not be activated
●
when the battery terminals are discon-
nected and then reconnected. If it occurs,
turn the engine switch off and then repeat
the following operation twice to activate
the audio system normally.
• Turn the engine switch to IGNITION ON
mode and then to OFF.
■
Hood
If the hood is opened while the engine is
●
stopped by the Stop & Start system, the
engine cannot be restarted by the Stop &
Start system or by the automatic engine
start function. Restart the engine with the
engine switch operation. (P.174)
Even if the hood is closed after the engine
●
is started with the hood open, the Stop &
Start system will not operate. Close the
hood, turn the engine switch off, wait 30
seconds or more, and then start the
engine.
Hill-start assist control
■
On a steep uphill grade, the vehicle may
●
roll backward after hill-start assist control
is released. In this situation, apply the
parking brake and operate the brake
pedal when putting the vehicle in motion.
●
This system operates on flat surfaces as
well as steep grades.
Sound may be generated from the
●
brakes, but this is not a malfunction.
●
When the engine is stopped due to Stop
& Start system operation, the force
required to depress the brake pedal may
change, but this is not a malfunction.
