Maintenance
• Make sure to follow the instructions indicated on the automated car wash.
• Fold in the door mirrors.
• For models equipped with automatic inte rmittent wipers, turn the wipers off.
• Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. St anding too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.
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 resin coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.

then open the hood. 1.Connect the first jumper cable to your
vehicle’s battery + terminal.
2. Connect the other end of the first jumper
cable to the booster battery + terminal.
u Use a 12-volt booster battery only.
u When using an automotive battery
charger to boost your 12-volt battery,
select a lower charging voltage than 15-
volt. Check the charger manual for the
proper setting.
3. Connect the second jumper cable to the
booster battery - terminal.
4. Connect the other end of the second
jumper cable to the engine mounting bolt

6. Attempt to start your ve hicle’s engine. If it
turns over slowly, check that the jumper
cables have good metal-to-metal contact.
■Jump Starting Procedure1 If the Battery Is Dead

cable ends to touch each other while attaching or
detaching the jumper cables.
Battery performance degrades in cold conditions and
may prevent the engi ne from starting.
