Your vehicle has an airbag system. Before attempting to
do your own service work, see Servicing Your
Airbag-Equipped Vehicle on page 1-72.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See Maintenance Record on page 6-17.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This can cause wind
noise and can affect fuel economy and windshield
washer performance. Check with your dealer/retailer
before adding equipment to the outside of your vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle. To help keep the
engine clean and maintain optimum vehicle
performance, we recommend the use of gasoline
advertised as TOP TIER Detergent Gasoline.
The 8th digit of the Vehicle Identification Number (VIN)
shows the code letter or number that identifies your
vehicle’s engine. The VIN is at the top left of the
instrument panel. See Vehicle Identification
Number (VIN) on page 5-109.
Gasoline Octane
If your vehicle has the 3.5L V6 engine (VIN Code N) or
the 3.9L V6 engine (VIN Code 1), use regular
unleaded gasoline with a posted octane rating of 87 or
higher. If the octane rating is less than 87, you might
notice an audible knocking noise when you drive,
commonly referred to as spark knock. If this occurs, use
a gasoline rated at 87 octane or higher as soon as
possible. If you are using gasoline rated at 87 octane or
higher and you hear heavy knocking, the engine
needs service.
