Adding Equipment to the
Outside of the Vehicle
Things added to the outside of the
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 the vehicle.
Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of this 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 the vehicle’s engine.
The VIN is at the top left of the
instrument panel. See Vehicle
Identification Number (VIN) on
page 5-79.
Gasoline Octane
If the vehicle has the 2.4L L4 engine
(VIN Code P) or the 3.5L V6 engine
(VIN Code N), 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.
If the vehicle has the 3.6L V6 engine
(VIN Code 7), use regular unleaded
gasoline with a posted octane
rating of 87 or higher. For best
performance or trailer towing, you
could choose to use middle grade
89 octane unleaded gasoline.
