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 Voltage 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 mo nths. Also, try to park in shaded areas
instead of direct sunlight.

Safety When Performing Maintenance
Some of the most important safe ty precautions are given here.
However, we cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not 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 fuel re lated parts, and all High Voltage system
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 Operate the engine only when there is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on le vel ground, the parking brake is set, and
the power system is turned off.
• Be aware that hot parts can burn you.
u Make sure to let the power system, including the engine and exhaust system,
cool thoroughly before touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not activate the power system unle ss instructed, and keep your hands and

uuCleaning uExterior Care
Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resi n coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. Use a sponge and mild detergent to wipe away promptly.
Be careful not to use harsh chemicals (including some commercial wheel cleaners) or
a stiff brush. They can damage the clear coat of the aluminum alloy wheels that
helps keep the aluminum from corroding and tarnishing.
