Over inflation causes rapid center wear and loss of
the tire's ability to cushion shocks (Fig. 26).
STANDARD PROCEDURE - TIRE PRESSURE
FOR HIGH SPEED OPERATION
DaimlerChrysler Corporation advocates driving at
safe speeds within posted speed limits. Where speed
limits allow the vehicle to be driven at high speeds,
correct tire inflation pressure is very important.
Vehicles loaded to maximum capacity should not be
driven at continuous speeds over 120 km/h (75 mph).
Never exceed the maximum speed capacity of the
tire. For information on tire identification and speed
ratings, (Refer to 22 - TIRES/WHEELS/TIRES -
DESCRIPTION).
STANDARD PROCEDURE - TIRE LEAK
REPAIRING
For proper repairing, a radial tire must be removed
from the wheel. Repairs should only be made if the
defect, or puncture, is in the tread area (Fig. 27). The
tire should be replaced if the puncture is located in
the sidewall.
Deflate tire completely before attempting to dis-
mount the tire from the wheel.Use a lubricant
such as a mild soap solution when dismounting
or mounting tire.Use tools free of burrs or sharp
edges which could damage the tire or wheel rim.
Before mounting tire on wheel, make sure all rust
is removed from the rim bead and repaint if neces-
sary.
Install wheel on vehicle, and progressively tighten
the 5 wheel nuts to a torque of 135 N´m (100 ft. lbs.).
CLEANING - TIRES
Before delivery of a vehicle, remove the protective
coating on the tires with white sidewalls or raisedwhite letters. To remove the protective coating, apply
warm water and let it soak for a few minutes. After-
wards, scrub the coating away with a soft bristle
brush. Steam cleaning may also be used to remove
the coating.
CAUTION: DO NOT use gasoline, mineral oil, oil-
based solvent or a wire brush for cleaning.
WHEELS
DESCRIPTION - WHEEL
Original equipment wheels are designed for proper
operation at all loads up to the specified maximum
vehicle capacity.
All models use either steel or aluminum drop-cen-
ter wheels. Every wheel has raised sections between
the rim flanges and rim drop well called safety
humps (Fig. 28). Initial inflation of the tires forces
the bead over these raised sections. In case of air
loss, the safety humps hold the tire in position on the
wheel until the vehicle can be brought to a safe stop.
Cast aluminum wheels require special balance
weights to fit on the flange of the rim (Fig. 29).
When wheel alignment is necessary on a vehicle
with cast aluminum wheels, special wheel clamps are
required to avoid damage to the wheel's finish.
The wheel studs and nuts are designed for specific
wheel applications and must be replaced with equiv-
alent parts.

²Panel repair for both flexible and rigid panels
are basically the same. The primary difference
between flexible panel repair and rigid panel repair
is in the adhesive materials used (Fig. 5).
²The technician should first decide what needs to
be done when working on any type of body panel.
One should determine if it is possible to return the
damage part to its original strength and appearance
without exceeding the value of the replacement part.
²When plastic repairs are required, it is recom-
mended that the part be left on the vehicle when
every possible. That will save time, and the panel
will remain stationary during the repair. Misalign-
ment can cause stress in the repair areas and can
result in future failure.
VISUAL INSPECTION
Composite materials can mask the severity of an
accident. Adhesive bond lines, interior structure of
the doors, and steel structures need to be inspected
carefully to get a true damage assessment. Close
inspection may require partial removal of interior
trim or inner panels.
Identify the type of repair: Puncture or Crack -
Damage that has penetrated completely through the
panel. Damage is confined to one general area; a
panel section is not required. However, a backer
panel, open fiberglass tape, or matted material must
be bonded from behind (Fig. 7) (Fig. 6).
PANEL SURFACE PREPARATION
If a body panel has been punctured, cracked, or
crushed, the damaged area must be removed from
the panel to achieve a successful repair. All spider
web cracks leading away from a damaged area must
be stopped or removed. To stop a running crack in a
panel, drilla6mm(0.250 in.) hole at the end of the
crack farthest away from the damage. If spider web
cracks can not be stopped, the panel would require
replacement. The surfaces around the damaged area
should be stripped of paint and freed from wax and
oil. Scuff surfaces around repair area with 360 grit
wet/dry sandpaper, or equivalent, to assure adhesion
of repair materials.
PATCHING PANELS
An panel that has extensive puncture type damage
can be repaired by cutting out the damaged material
(Fig. 7). Use a suitable reciprocating saw or cut off
wheel to remove the section of the panel that is dam-
aged. The piece cut out can be used as a template to
shape the new patch. It is not necessary to have
access to the back of the panel to install a patch.
Bevel edges of cutout at 20 degrees to expose a larger
bonding area on the outer side. This will allow for an
increased reinforcement areas.

BODY LUBRICATION
LUBRICATION REQUIREMENTS
Body mechanisms and linkages should be
inspected, cleaned, and lubricated, as required, to
maintain ease of operation and to provide protection
against rust and wear. When performing other under
hood services, the hood latch release mechanism and
safety catch should be inspected, cleaned, and lubri-
cated. During the winter season, external door lock
cylinders should be lubricated to assure proper oper-
ation when exposed to water and ice.
Prior to the application of any lubricant, the parts
concerned should be wiped clean to remove dust and
grit. If necessary, a suitable solvent can be used to
clean the item to be lubricated. After lubricating a
component, any excess oil or grease should be
removed.
LUBRICANT APPLICATION
DOOR LOCK CYLINDERS
(1) Apply a small amount of lubricant directly into
the lock cylinder.
(2) Apply a small amount of lubricant to the key.(3) Insert key into lock cylinder and cycle the
mechanism from the locked to the unlocked position.
NOTE: Do not add more lubricant.
(4) Cycle the lock cylinder mechanism several
times to allow the lubricant to flow throughout the
cylinder.
(5) Wipe all lubricant from exterior of lock cylinder
and key.

PAINT CODE
DESCRIPTION
Exterior vehicle body colors are identified on the
Body Code plate. (Refer to VEHICLE DATA/VEHI-
CLE INFORMATION/BODY CODE PLATE -
DESCRIPTION). The paint code is also identified on
the Vehicle Safety Certification Label which is
located on the drivers door shut face. The first digit
of the paint code listed on the vehicle indicates the
sequence of application, i.e.: P = primary coat, Q =
secondary coat. The codes listed in the Color Code
Chart are used for manufacturing purposes.
PAINTED TOUCH-UP
DESCRIPTION
When a painted metal surface has been scratched
or chipped, it should be touched up as soon as possi-
ble to avoid corrosion. For best results, use Mopart
Scratch Filler/Primer, Touch Up Paints and Clear Top
Coat. (Refer to VEHICLE DATA/VEHICLE INFOR-
MATION/BODY CODE PLATE - DESCRIPTION).
WARNING: USE A OSHA APPROVED BREATHING
MASK WHEN SPRAYING PAINT OR SOLVENTS IN A
CONFINED AREA. PERSONAL INJURY CAN
RESULT.
TOUCH UP PROCEDURE
(1) Scrape loose paint and corrosion from inside
scratch or chip.
(2) Clean affected area with MopartTar/Road Oil
Remover, and allow to dry.
(3) Fill the inside of the scratch or chip with a coat
of filler/primer. Do not overlap primer onto good sur-
face finish. The applicator brush should be wetenough to puddle-fill the defect without running. Do
not stroke brush applicator on body surface. Allow
the filler/primer to dry hard.
(4) Cover the filler/primer with color touch up
paint. Do not overlap touch up color onto the original
color coat around the scratch or chip. Butt the new
color to the original color, if possible. Do not stroke
applicator brush on body surface. Allow touch up
paint to dry hard.
(5) On vehicles without clearcoat, the touch up
color can be lightly finesse sanded (1500 grit) and
polished with rubbing compound.
(6) On vehicles with clearcoat, apply clear top coat
to touch up paint with the same technique as
described in Step 4. Allow clear top coat to dry hard.
If desired, Step 5 can be performed on clear top coat.
WARNING: AVOID PROLONGED SKIN CONTACT
WITH PETROLEUM OR ALCOHOL ± BASED CLEAN-
ING SOLVENTS. PERSONAL INJURY CAN RESULT.
FINESSE SANDING/BUFFING &
POLISHING
DESCRIPTION
Minor acid etching, orange peel, or smudging in
clearcoat or single-stage finishes can be reduced with
light finesse sanding, hand buffing, and polishing.If
the finish has been finesse sanded in the past,
it cannot be repeated. Finesse sanding opera-
tion should be performed by a trained automo-
tive paint technician.
CAUTION: Do not remove clearcoat finish, if
equipped. Basecoat paint must retain clearcoat for
durability.

control rear set temp button is pressed simulta-
neously with the rear control head, then the front
control head press events shall have priority, i.e. if
the front user presses Rear Set Temp down and the
rear user presses Set Temp up, then the rear set
temp will decrease.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - A/C COOL DOWN
TEST
The heater-A/C control module can perform an A/C
cool down test, which is a test performed during the
manufacturing process to confirm that the air condi-
tioning system is performing satisfactorily. This test
can also provide a quick confirmation of air condi-
tioning system performance to the service technician.
If the test is completed satisfactorily, no further ser-
vice is required. If the test is failed, proceed to the
A/C Performance Test to confirm the a/c system is
operating properly, or use a DRBIIItscan tool to
diagnose the A/C system control and distribution sys-
tems. Refer to the appropriate diagnostic informa-
tion.
MANUAL TEMPERATURE CONTROL
The front blower speed and rear blower speed (if
equipped with rear HVAC) must be set to High and
the evaporator temperature sensor must be greater
than 55É F or the test will fail immediately. The test
is activated by depressing the A/C and PWR buttons
simultaneously and holding them depressed for no
less than five seconds. The PWR and A/C LEDs will
blink on and off until the test is complete. If the
LEDs stop blinking before two minutes, then the cool
down test has been completed successfully. If the two
minutes expire without the expansion valve temper-
ature reaching 20É F less than the outside air tem-
perature, then the cool down test has been failed and
further A/C system diagnosis is required. If the test
is failed, the LEDs will continue to blink until the
vehicle has been driven for greater than (8 miles).
AUTOMATIC TEMPERATURE CONTROL
The ambient air temperature in the room where
the vehicle will be tested must be a minimum of 21É
C (70ÉF) for this test. The test is activated by
depressing the A/C and PWR buttons simultaneously
and holding them depressed for no less than four sec-
onds. The snowflake icon and the DELAY text in the
ATC display will blink on and off alternately until
the test is complete. If the snowflake icon and the
DELAY text stop blinking before two minutes, then
the cool down test has been completed successfully. If
the two minutes expire without the evaporator tem-perature reaching 20É F less than the evaporator ini-
tial temperature, then the cool down test has been
failed and further A/C system diagnosis is required.
If the test is failed, the snowflake icon and the
DELAY text will continue to blink across ignition
cycles until the vehicle has been driven for greater
than (8 miles).
DIAGNOSIS AND TESTING - A/C
PERFORMANCE TEST
An air conditioning performance test is the best
way to determine whether the system is performing
up to standard. This test also provides valuable clues
as to the possible cause of trouble with the air con-
ditioning system. The ambient air temperature in the
location where the vehicle will be tested must be a
minimum of 21É C (70ÉF) for this test.
WARNING: REFER TO THE APPLICABLE WARN-
INGS AND CAUTIONS FOR THIS SYSTEM BEFORE
PERFORMING THE FOLLOWING OPERATION.
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - FRONT - WARNING - A/C PLUMBING)
and (Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - FRONT - CAUTION - A/C PLUMBING).
NOTE: When connecting the service equipment
coupling to the line fitting, verify that the valve of
the coupling is fully closed. This will reduce the
amount of effort required to make the connection.
(1) Connect a tachometer to monitor the engine
speed.
(2) Remove the caps from the refrigerant system
service ports and attach a manifold gauge set to
monitor the refrigerant system pressures.
(3) Set the heater-air conditioner controls so that
the compressor is engaged, the air within the vehicle
is being recirculated, the output air is directed
through the panel outlets, the temperature control is
in the full cool position, and the blower motor is oper-
ating at its highest speed.
(4) Start the engine and allow the engine to oper-
ate for about five minutes or until it reaches normal
operating temperature. Then hold the engine speed
at 1000 rpm with the compressor clutch engaged. If
the compressor clutch does not engage, proceed with
diagnosis of the compressor clutch coil. (Refer to 24 -
HEATING & AIR CONDITIONING/CONTROLS -
FRONT/COMPRESSOR CLUTCH COIL - DIAGNO-
SIS AND TESTING).
(5) Close all the vehicle windows and doors.
(6) Insert a thermometer in the left center panel
outlet and operate the engine for five minutes.
