The red Charging System Warning light should come on briefly when you
turn on the ignition, before starting the engine, as a check to show you it is
working. After the engine starts, the light should go out. If it stays on or
conles on while you are driving, you may have a problem with your
charging system.
It could indicate a problem with the alternator drive belt,
or some other charging system problem. Have
it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light on, it helps to turn off all
your accessories, such
as the radio and air conditioner.

This orange light should come on when the ignition is on

not come on at all, have
it fixed right away. If it stays on, or comes on while
you are driving, the computer is indicating that you have a problem. You
should take your vehicle in for service soon.

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

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.

When it’s Time for New Tires
Tread Wear
Indicators
One way to tell when
it’s time for new tires
is to check the
treadwear indicators,
which will appear
when your tires have
only
1/16 inch (1.6
mm) or less of tread
remaining.
You need a new tire if
0 You can see the indicators at three or more places around the tire.
e You can see cord or fidbric showing through the tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep enough to show
cord
or fabric.
0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut, or other damage that can’t be repaired well
because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at the
Certification/Tire label.
The tires installed
on your vehicle when it was new had a Tire Performance
Criteria Specification (TPC Spec) number on each tire’s sidewall. When you
get new tires, get ones with that same TPC Spec number. That way, your
vehicle will
continue to have tires that are designed to give proper
endurance, handling, speed rating, traction, ride and other things during
normal service
on your vehicle. If your tires have an all-season tread
design, the TPC number
will be followed by an “MS” (for mud and snow).
If
you ever replace your tires with those not having a TPC Spec number,
make sure
they are the same size, load range, speed rating and construction
type (bias, bias-belted or radial)
as your original tires.
