Engine Control Module System
Gasoline Engines
This system has an oxygen sensor
(OS)
that helps keep your engine's
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle. If
you use leaded fuel, you could damage your oxygen sensor (OS) and
three-way catalytic converter.
Diesel Vehicles Below 8,500 (3 850 Kg) GVWR
This system monitors engine speed and throttle position. It adjusts exhaust
gas recirculation to limit emissions.
Malfunction Indicator (SERVICE ENGINE SOON)
Light
The Malfunction Indicator (SERVICE ENGINE SOON) Light on your
instrument panel lets you know when your emission system needs service.
The light will come on briefly when you start your engine to let you know
that the system is working. If it does not come on when you start your
engine, or if it comes on and
stays on
while you're driving, your system
may need service. Your vehicle should still be driveable, but you should
have your system serviced right away.
Secondary Air Injection Reaction (AIR) System
(Gasoline Engines)
You may have this system. It has a control valve that will direct air to where
it is needed. If the AIR system needs service, your Malfunction Indicator
(SERVICE ENGINE SOON) Lamp on your instrument panel will come on.
Tires
We don't make tires. Your new vehicle comes with high-quality tires made
by a leading tire manufacturer. These tires are warranted by the tire
manufacturers, and their warranties are delivered with every new vehicle. If
your spare tire is a different brand than your road tires, you will have a tire
warranty folder from each of these manufacturers.
