INTERIOR CLEANING
Upholstery
Fabric can usually be cleaned with soapy water or
a proper detergent. For more difficult spots caused by
oil, ice cream, soda, etc., use a fabric cleaner avail-
able at most parts stores. Be sure when purchasing
the cleaner to read the label to ensure it is safe to use
on your type of fabric. A safe method of testing the
cleaner is to apply a small amount to an area usually
unseen, such as under a seat, or other areas. Wart a
while, perhaps even a day to check the spot for fad-
ing, discoloring, etc., as some cleaners will only
cause these problems after they have dried
Leather upholstery requrres special care, it can be
cleaned with a mild soap and a soft cloth. It is recom-
mended that a special leather cleaner be used to
clean but also treat the leather surfaces in your vehi-
cle. Leather surfaces can age quickly and can crack if
not properly taken care of, so it is vital that the leather
surfaces be maintained.
Floor Mats and Carpet
The floor mats and carpet should be vacuumed or
brushed regularly. They can be cleaned with a mild
soap and water. Special cleaners are available to
clean the carpeted surfaces of your vehicle, but take
care in choosing them, and again it is best to test
them in a usually unseen spot.
Dashboard, Console, Door Panels, Etc.
The dashboard, console, door panels, and other
plastic, vinyl, or wood surfaces can be cleaned using
a mild soap and water. Caution must be taken to keep
water out of electronic accessories and controls to
avoid shorts or ruining the components Again spe-
cial cleaners are available to clean these surfaces, as
with other cleaners care must taken in purchasmg
and using such cleaners.
There are protectants available which can treat the
various surfaces in your car giving them a “shiny new
look”, however some of these protectants can cause
more harm than good in the long run. The shine that
is placed on your dashboard attracts sunlight accel-
erating the aging, fading and possibly even cracking
the surfaces. These protectants also attract more dust
to stick to the surfaces they treat, Increasing the cleaning you must do to maintain the appearance of
your vehicle. Personal discretion is advised here.
On most models covered by this manual, the
wheel bearmgs used are sealed units and do not re-
quire routine maintenance. However on some Galant
and Mirage models, the rear wheel bearing do require
periodic repacking. For removal and installation in-
structions, please refer to Section 7 (for rear bear-
ings) or Section 8 (for front bearings).
REPACKING
*Sodium based grease is not compatible
with lithium based grease. Read the package
labels and be careful not to mix the two
types. If there is any doubt as to the type of
grease used, completely clean the old
grease from the bearing and hub before re-
placing.
Before handling the bearings, there are a few
things that you should remember to do and not to do.
DO the following: l Remove all outside dirt from the housing be-
fore exposing the bearing.
l Treat a used bearing as gently as you would a
new one.
l Work with clean tools in clean surroundings. l Use clean, dry gloves, or at least clean, dry
hands.
l Clean solvents and flushing fluids are a must. l Use clean paper when laying out the bearings
to dry.
l Protect drsassembled bearings from rust and
dirt. Cover them up.
l Use clean, lint-free rags to wipe the bearings. l Keep the bearings in oil-proof paper when they
are to be stored or are not in use.
l Clean the inside of the housing before replac-
ing the bearin
Do NOT do he followino: El, l Do not work in dirty sirroundings. l Do not use dirty, chipped or damaged tools. l Do not work on wooden work benches or use
wooden mallets.
l Do not handle bearings with dirty or moist
hands.
l Do not use gasoline for cleaning. Use a safe
solvent.
l Do not spin dry bearings with compressed air.
They will be damaged.
l Do not use cotton waste or dirty cloths to wipe
bearings.
l Do not scratch or nick bearing surfaces. l Do not allow the bearina to come in contact
” with dirt or rust at any time.
The rear wheel bearinas on some Galant and Mi-
rage models require periodic maintenance. A pre-
mium high melting point grease meeting Grade
Multipurpose Grease NLGI Grade #2 or equivalent
must be used. Long fiber type greases must not be
used. This service is recommended every 30,000
miles (48,000 km).
*For information on Wheel Bearing removal
and installation, refer to Section 7 of this
manual.
1. Remove the wheel bearing.
2. Clean all parts in a non-flammable solvent and
let them air dry.
*Only use lint-free rags to dry the bearings.
Never spin-dry a bearing with compressed
air, as this will damage the rollers.
3. Check for excessive wear and damage. Replace
the bearing as necessary.
*Packina wheel bearinos with arease is
best accomplished by u&g a wheel bearing
packer (available at most automotive parts
stores).
4. If a wheel bearing packer is not available, the
bearings may be packed by hand.
a. Place a “healthy’ glob of grease in the
palm of one hand.
b. Force the edge of the bearing into the
grease so that the grease fills the space between
the rollers and the bearing cage.
c. Keep rotating the bearing while continuing
to push the grease through.
d. Continue until the grease is forced out the
other side of the bearing.
5. Place the packed bearing on a clean surface
and cover it until it is time for installation.
6. Install the wheel bearing.

To prevent the bumper from deforming, these vehi-
cles cannot be towed by a wrecker using sling-type
equipment. If these vehicles require towing, use a
wheel lift or flat bed equipment. It is recommended
that the vehicle be towed from the front If a flat bed is
not available.
Manual transaxle vehicles may be towed from the
rear provided that the transaxle is in Neutral and the
driveline has not been damaged. The steering wheel
must be clamped in the straight-ahead positron with a
steering wheel clamping device designed for towing
service use.
Do not use the steering column lock to secure
the front wheel uosition for towina.
Automatic transaxle vehicles may be towed on the
front wheels at speeds not to exceed 30 mph (50
km/h) for a distance not to exceed 18 miles (30 km).
If these limits can not be met, then the front wheels
must be placed on a tow dolly.
# See Figure 221
All Wheel Drive (AWD) vehicles should only be
towed with all 4 wheels on the ground or lifted from
the road surface. This means that the vehicle is to be
towed either with flatbed equipment, with all wheels
on dollies or flat towed. Damage to the viscous cou-
pling may result if the vehicle is towed with only 2
wheels on the ground.
p See Figure 222
Whenever a vehicle is jump started, precautions
must be followed In order to prevent the possibility of

personal injury. Remember that batteries contain a
small amount of explosive hydrogen gas which is a
by-product of battery charging. Sparks should always
be avoided when working around batteries, especially
when attaching jumper cables. To minimize the pos-
sibility of accidental sparks, follow the procedure
carefully.
NEVER hook the batteries up in a series cir-
cuit or the entire electrical system will go up
in smoke. includino the starter!
Vehicles equipped with a diesel engine may utilize
two 12 volt batteries. If so, the batteries are con-
nected in a parallel circuit (positive terminal to posi-
tive terminal, negative terminal to negative terminal).

. For4WD models, the basic principle is that
all four wheels are to be rarsed before
towing.
. The shift lever should be set to 1 st gear and
the parking brake should be applied.

Hooking the batteries up in parallel circuit increases
battery cranking power without increasing total bat-
tery voltage output. Output remains at 12 volts. On
the other hand, hooking two 12 volt batteries up in a
series circuit (positive terminal to negative terminal,
positive terminal to negative terminal) increases total
battery output to 24 volts (12 volts plus 12 volts).
l Be sure that both batteries are of the same volt-
age. Vehicles covered by this manual and most vehi-
cles on the road today utilize a 12 volt charging sys-
tem.
l Be sure that both batteries are of the same po-
larity (have the same terminal, in most cases NEGA-
TIVE grounded).
l Be sure that the vehicles are not touching or a
short could occur.
l On serviceable batteries, be sure the vent cap
holes are not obstructed.
l Do not smoke or allow sparks anywhere near
the batteries.
l In cold weather, make sure the battery elec-
trolyte is not frozen, This can occur more readily in a
battery that has been in a state of discharge.
l Do not allow electrolyte to contact your skin or
clothing.
1. Make sure that the voltages of the 2 batteries
are the same. Most batteries and charging systems
are of the 12 volt variety.
