SPORT+ mode optimizes dynamic response
from all powertrain an d chassis systems -
perfect for your favorite winding road.
• EV operation is elimin ated while operating
in SPORT+ .
TRACK mode gives maximum, consistent
performance from dyna mic systems during
track day lapping sessions. Hybrid battery
charge is maintained for consistent
performance.
• VSA ® OFF indicator is illuminated in TRACK
mode indicating reduced stability control.
This allows more body side slip and wheel
spin before VSA ® begins to operate.
• Integrated Dynamics switch must be turned
and held to the right for several seconds to
engage TRACK mode.

uuWhen Driving uHigh Voltage Battery
Driving
High Voltage Battery
The High Voltage battery gradually discharges when the vehicle is not in use. As a
result, if your vehicle is parked for an ex tended period of time, the battery level may
get low. Keeping the High Vo ltage battery’s charge level low can shorten its life.
To maintain the High Voltage battery, driv e your vehicle for more than 30 minutes
to recharge it at least once every three months. Also, try to park in shaded areas
instead of direct sunlight.

Safety When Performing Maintenance
Some of the most important safety precau tions are given here. However, we cannot
warn you of every conceivable hazard that can arise in performing maintenance.
Only you can decide whether you should perform a given task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood and hatch.
u Heat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the 12-volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.
