Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having it serviced by your dealer/retailer before departing.
Things to check on your own include:
• Windshield Washer Fluid: Reservoir full? Windows
clean — inside and outside?
• Wiper Blades: In good shape?
• Fuel, Engine Oil, Other Fluids: All levels checked?
• Lamps: Do they all work and are lenses clean?
• Tires: Are treads good? Are tires inflated to
recommended pressure?
• Weather and Maps: Safe to travel? Have
up-to-date maps?
