After the engine is stopped by the Stop & Start system when the vehicle is on an
incline, brake force is temporarily maintained to prevent rolling backwards until
the engine is restarted and drive force is generated.
When drive force is generated, the ma intained brake force is automatically
canceled.
●This function operates on flat surfaces as well as steep inclines.
●Sound may be generated from the brak es, but this is not a malfunction.
●Brake pedal response may change and vibration may occur, but these are not
malfunctions.
■Operating conditions
●The Stop & Start system is operational when all of the following conditions are met:
• The brake pedal is being depressed firmly.
• The shift lever is in D or P.
• Normal mode or Eco drive mode is selected as the driving mode.
• is off.
• The driver’s seat belt is fastened.
• The engine is adequately warmed up.
• The driver’s door is closed.
• The accelerator pedal is not being depressed.
• The outside temperature is -5°C (23°F) or higher.
• The hood is closed.
●In the following situations the engine may not be stopped by the Stop & Start system.
This is not a malfunction of the Stop & Start system.
• The air conditioning system is being used when the ambient temperature is high or
low.
• The battery is not sufficiently charged, such as if the vehicle has been parked for a long time and the battery charge has decreased, the electric load is large, the bat-
tery temperature is excessively low or the battery has deteriorated, or is undergoing
a periodic recharge.
• The brake booster vacuum is low.
• The vehicle is stoppe d on a steep incline.
• The steering wheel is being operated.
• Due to traffic or other circumstances the vehicle is stopped repeatedly.

• The battery is not sufficiently charged.
■If the steering wheel is turned shortly after the engine has started
If the steering wheel is turned shortly after the engine has been started by the Stop &
Start system, the steering wheel may feel heavy.
■Hood
●If the hood is opened while the engine is stopped by the Stop & Start system with the
shift lever in D, the engine will stall and will not be able to be restarted by the automatic
engine start function. In this case, restart the engine using the normal engine starting
procedure. ( P. 204)
●If the hood is opened while the engine is stopped by the Stop & Start system with the
shift lever in P, the engine will be restarted automatically.
●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 sec-
onds or more, and then start the engine.
■When to use the Stop & Start system

●When the engine cannot be stopped by the Stop & Start system
MessageDetails
“Depress Brake
Firmly to Activate.”
The brake pedal is not depressed enough. If the brake pedal is depressed further, the sys-
tem will operate.
“For Climate Con-
trol.”
• The air conditioning system is being used when the ambient temperature is high or low.
If the difference between the set temperature
and cabin temperature is small, the system will be
enabled.
• is ON.
“Battery Charging.”
• The battery charge amount may be low. Engine stop is temporarily prohibited to priori-
tize charging of the battery, but if the engine is
operated for a short while, engine stop is
allowed.
• A refresh charge may be occurring, such as when the battery is undergoing a periodic
recharge, for a while after the battery terminals
have been disconnected and reconnected, for
a while after the battery has been replaced, etc.
After a refresh charge of approximately 5 to 60
minutes completes, the system can be operated.
• The engine may have been started with the hood opened.
Close the hood, turn the engine switch off, wait
30 seconds or more, and then start the engine.
• The battery may be cold.
Operating the engine for a short while allows the

increase in the engine compartment.
• The battery may be extremely hot. If the engine compartment is allowed to cool suf-
ficiently, the system recovers.
If the message is displaye d continuously (more than
60 minutes), the battery may have deteriorated.
