Quick Reference Guide
Auto Engine Stop/Start
Your vehicle’s gasoline engine will automatically stop and start during vehicle operation as needed to meet driving and battery conditions.
These are some examples that could cause the gasoline engine to automatically start.
In the following cases, however, Auto Engine Stop may not activate.
●When the Integrated Dynamics System is in SPORT+ mode or TRACK mode.●The vehicle momentarily needs additional power for aggressive acceleration, or driving uphill or at high speed.●The climate control system is in heavy use.●The High Voltage battery temperature is high or low.●The High Voltage battery state of charge is low.●The engine coolant temperature is low.●When the door is opened after releasing seatbelt.●When the shift position is in M (Manual) mode.
About Your Vehicle’s Limited Operating Temperature
If the outside temperature is about -4°F (-20°C), some operation might be limited.
The limited operation is listed below:
2 High Voltage Battery (P94)
2 Dual Clutch Transmission (P323)
2 Shifting (P324)
Sounds Unique to th e SPORT HYBRID SH-AWD ® System
When you first start driving this vehicle, you likely will hear so me unfamiliar sounds, particularly when you first turn on the power system,
while driving, and just after parking. Some of these sounds are unique to this ve hicle‘s powertrain, fuel, and climate control systems; others
are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a vehicle of this design.
These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any new or unus ual noise
should one develop.
About a system to cool the High Voltage battery using the climate control system.●The system will not be activated when the defroster is ON.●When the outside temperature is in extreme hot or cold condit ion, the system may not provide sufficient cooling performance to the
High Voltage battery due to the protection of the electric A/C compressor.
●When the system is active, the climate control system may not work sufficiently.

■Electric motor
The degree to which the electric motor is being powered is displayed by the readings
on the ASSIST side.
■Battery charge in progress
The degree to which the High Voltage battery is being charged is displayed by the
readings on the CHARGE side.
■Temperature Gauge
■High Voltage Battery Charge Level Gauge
■ASSIST/CHARGE Gauge
1Temperature Gauge
Driving with the temperat ure gauge pointer in the
upper zone can cause serious engine damage. Pull
safely to the side of th e road and allow engine
temperature to return to normal. 2 Overheating P. 452
1High Voltage Battery Charge Level Gauge
The High Voltage battery ch arge level may decrease
under the following conditions:
•When the 12-volt battery has been replaced.
•When the 12-volt battery has been disconnected.•When the High Voltage battery control system
corrects its reading.
The charge level reading will be corrected
automatically while driving.
Changes in the temperature of the High Voltage
battery can increase or decrease the battery’s
charging capacity. If temp erature changes cause the
battery’s capacity to change, the number of
indicators in the battery ch arge level gauge may also
change, even if the amount of charging remains the
same.

from diesel-powered vehicles, replace the dust and pollen filters every 15,000 miles (24,000 km) or
every year.
*4: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperature. This requires transmission fluid and clutch fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under this condition, have the transmission
fluid and clutch fluid changed every 20,000 miles (32,000 km).
*5: Driving in mountainous areas at very low vehicle speeds results in higher level of mechanical (Shear) stress to fluid. This requires Twin Motor Unit fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under these conditions, have the Twin Motor
Unit fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).
