Circuit Description
In order to control emissions, a catalytic converter is used to covert harmful emissions into harmless water vapor and
carbon dioxide. The ECM has the ability to monitor this process by using a oxygen sensor. The oxygen sensor pro-
duces and output signal which indicates the storage capacity of the catalyst. This in turn indicates the catalyst’s ability
to convert exhaust emission effectively. If the oxygen sensor pigtail wiring, connector, or terminal is damaged. Do not
attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly, it must have a clean air
reference provided to it. This clean air reference is obtained by way of the oxygen sensor wire(s). Any attempt to repair
the wires, connector, or terminal and degrade the oxygen sensor performance.

TIRE AND WHEELS 2E-3
SSANGYONG MY2002
TIRE CHAIN USAGE
Due to limited tire-to-body clearance on certain
vehicles, recommendations for tire chain use are
published in the Owner’s Manual. When tire chains
need to be used, most current Ssangyong vehicles
require SAE Class “S” tire chains. These may also be
designated as 1100 Series, type PL tire chains. These
chains are specifically designed to limit the “fly off”
effect which occurs when the wheel rotates.
Be sure that only fine-link chains are used which do
not add more than 15 mm (0.590 inch), including the
lock, to the tread surface and the inner sides of the
tires. Manufacturers of tire chains have a specific chain
size for each tire size to ensure a proper fit when the chain
is installed. Be sure to purchase the correct chains for the
tires on which they are to be used. Use rubber adjusters to
take up any slack or clearance in loose chains.
Use of chains may adversely affect vehicle handling.
When tire chains are installed, follow these precautions:
Adjust speed to road conditions.
Avoid sharp turns.
Avoid locked-wheel braking.
To prevent chain damage to the vehicle, install the
chains on the front tires as tightly as possible. Tighten
them again after driving 0.4 to 0.8 kilometer (0.3 to 0.5
mile). The use of chains on the rear tires is not recom-
mended because they may contact the vehicle and pos-
sibly damage it. If chains must be used on the rear
tires, be sure there is sufficient clearance between the
chains and the body. Do not exceed 70 km/h (45 mph)
or the chain manufacturer’s speed limit, if lower. Avoid
large bumps, potholes, severe turns and any other
maneuvers which could cause the tires to bounce.
Follow any other instructions of the chain manufacturer
which do not disagree with the above instructions.
REPLACEMENT TIRES
A tire performance criteria (TPC) specification number
is molded in the sidewall near the tire size of all original
equipment tires. This specification number assures that
the tire meets performance standards for traction, en
durance, dimensions, noise, handling and rolling
resistance. Usually a specific TPC number is assigned
to each tire size.
Caution: Do not mix different types of tires on the
same vehicle such as radial, bias and bias-belted
tires except in emergencies, because vehicle han-
dling may be seriously affected and may result in
loss of control.Use only replacement tires with the same size, load
range, and construction as the original. The use of any
other tire size or construction type may seriously affect
ride, handling, speedometer/odometer calibration, ve-
hicle ground clearance, and tire clearance to the body
and the chassis. This does not apply to the spare tire
furnished with the vehicle.
It is recommended that new tires be installed in pairs
on the same axle.
If it is necessary to replace only one tire, pair it with the
tire having the most tread to equalize the braking action.
Although they may appear different in tread design, tires
built by different manufacturers with identical TPC speci-
fications may be used on the same vehicle.
ALL SEASON TIRES
Most vehicles are now equipped with steel-belted all
season radial tires as standard equipment. These tires
qualify as snow tires, with a 37 percent higher average
rating for snow traction than the non-all season radial
tires previously used. Other performance areas, such
as wet traction, rolling resistance, tread life, and air
retention, have also been improved. This was done by
improvements in both tread design and tread
compounds. These tires are identified by an “M + S”
molded in the tire sidewall following the size number.
The suffix “MS” is also molded in the sidewall after
the TPC specification number.
The optional handling tires used on some vehicles are
not all season tires. These will not have the “MS” mark-
ing after the tire size or the TPC specification number.
PASSENGER METRIC SIZED TIRES
All Daewoo vehicles now use passenger (P) metric sized
tires. P-metric tires are available in two load ranges:
standard load (35 psi maximum) and extra load (41 psi
maximum). Most passenger vehicle tires are standard
load.
Most P-metric tire sizes do not have exact correspond-
ing alphanumeric tire sizes. For example, a P175/70R13
is not exactly equal in size and load-carrying capacity
to an FR70-13. For this reason, replacement tires should
be of the same TPC specification number as the origi-
nals. If P-metric tires must be replaced with other sizes,
consult a tire dealer. Tire companies can best recom-
mend the closest match of alphanumeric to P-metric
sizes within their own tire lines.
The metric term for measuring tire inflation pressure is
the kilopascal (kPa). Tire pressure may be printed in
both kPa and psi. One psi equals 6.895 kPa.
See the tire label or refer to “Tire Size and Pressure
Specifications” in this section for tire inflation
pressures.

2E-4 TIRE AND WHEELS
TIRE LABEL
The tire label is permanently located on the rear face
of the driver’s door and should be referred to for tire
information. It lists the maximum vehicle load, the tire
size (including the spare tire), and the cold inflation
pressure (including the spare tire).
S PARE TIRE
This vehicle comes equipped with a full-sized spare
tire and wheel.
The temporary spare tire is designed for emergency
use only. The original tire should be repaired or replaced
at the first opportunity and reinstall.
WHEELS
Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, leak air through
welds, have elongated bolt holes, or if the wheel bolts
won’t stay tight or are heavily rusted. Wheels with
excessive runout may cause vehicle vibration.
Replacement wheels must be equivalent to the original
equipment wheels in load capacity, diameter, rim width,
offset, and mounting configuration. A wheel of improper
size or type may affect wheel and bearing life, brake
cooling, speedometer/odometer calibration, vehicle
ground clearance, and tire clearance to the body and
the chassis. The wheel offset is 49 ± 1 (1.93 ± 0.04
inches). Steel wheels may be identified by a two- or
three-letter code stamped into the rim near the valve
stem. Alloy wheels should have the code, the part
number, and the manufacturer ID cast into the back
side.
INFLATION OF TIRES
The pressure recommended for any vehicle line is care-
fully calculated to give a satisfactory ride, handling,
tread life, and load-carrying capacity.
Tire pressure should be checked monthly or before any
extended trip. Check the tires when they are cold, after
the vehicle has sat for 3 hours or more or has been
driven less than 1 mile. Set the tire pressure to the
specifications on the tire label located on the rear face
of the drive r ’s door. Tire inflation pressure is also given
under “Tire Size and Pressure Specifications” in
this section.
Valve caps or extensions should be on the valves to
keep dust and water out.
For sustained driving at speeds up to 140 km/h (85 mph),
inflate the tires to the pressure recommended on the
tire. Sustained driving at speeds faster than 140 km/h
(85 mph), even if permitted by law, is not advised unless
the vehicle has special high-speed tires available from
many tire dealers. Tire pressures may increase as much
as 41 kPa (6 psi) when the tires are hot.
Higher than recommended tire pressure can cause
Hard ride.
Tire bruising or damage.
Rapid tread wear at the center of the tire.
Lower than recommended pressure can cause
Tire squeal on turns.
Hard steering.
Rapid and uneven wear on the edges of the tread.
Tire rim bruises and rupture.
Tire cord breakage.
High tire temperatures.
Unequal tire pressures on same axle can cause
Uneven braking.
Steering lead.
Reduced handling.
Swerve on acceleration.
Torque steer.
