the A-pillar. The SKREEM receives radio messages
from the RKE transmitter (fob) and sends com-
mands via the RKE Interface circuit to the CTM. If
the vehicle is equipped with VTSS, the Security
System Module will be connected in series between
the SKREEM and the CTM.
Confirmation of the RKE Lock/Unlock state is
accomplished via the turn signals. When the vehicle
is locked via RKE the turn signals will flash three
times. When it is unlocked via RKE, the turn
signals will flash one time. If the vehicle has been
unlocked via RKE and no door is opened within 40
seconds, the entire vehicle will be locked again
automatically.
If a transmitter (fob) is operated more than 255
times in succession beyond the range of the receiver
(SKREEM), the RKE portion of the key will become
inoperative. In order to put it back in synchroniza-
tion it will be necessary to have ALL the other
transmitters that are used with this vehicle avail-
able and follow the following procedure:
1. Cycle the ignition on and off 2 times within 6
seconds (leave in off position).
2. Press the lock or unlock button of the disabled
transmitter within 3 seconds of turning the
ignition off.
3. Press any button (lock or unlock) 3 more times
within 6 seconds.
4. Wait 10 seconds.
5. Press any button of ALL other transmitters
belonging to this vehicle at least once within
the next 20 seconds.
For problems related to the Immobilizer function
of the SKREEM, see Service Information.
3.5.3 AUTO DOOR LOCKS
Whenever the engine is started, the CTM receives
a message to lock all doors except the drivers door.
This is accomplished through the D+ Relay. The D+
Relay is controlled by the Instrument Cluster which
receives a command from the ECM that the engine
is running. This relay supplies power to the CTM
(for auto locking), the daytime running lamps and
the rear window defogger.
3.5.4 ACCIDENT RESPONSE
The CTM is hardwired to the Airbag Control
Module through the Enhanced Accident Report
Driver circuit. Anytime the vehicle airbags are
deployed, the CTM will unlock all doors and a
9Crash9DTC will be stored in memory. The door
locks will be inoperative until that code is cleared. If
the vehicle is severly jarred, but not enough to
deploy the airbags, it is possible that the DTC could
be set and therefore the door locks would be inop-
erable. Whenever the door locks are not opera-tional, use the DRBIII and check DTC's . If the code
9ACM has unlocked the doors9appears, use the
DRBIII and erase it.
3.6 VEHICLE THEFT SECURITY SYSTEM
(VTSS)
The Security System Module (SSM) is located
under the driver's seat. The SSM communicates
with the DRBIII over the K-line. If equipped the
Vehicle Theft Security System will monitor the
following:
²door jamb switches
²hood ajar switch
²ignition switch
²interior of the vehicle for movement
²longitudinal and transverse movement of the
vehicle
²rear defogger grids for glass breakage
²trailer connector
To arm the system the hood and all of the doors
must be closed when the vehicle is locked with the
RKE transmitter or with the use of the key in the
driver door. If the key is used, it must be held in the
lock position for 2 seconds. When the system is first
activated, the hazard lamps will flash 3 times. Also
with the system armed, the Towing/Intrusion Sen-
sor On/Off Switch indicator will flash to indicate an
armed system. To disarm the system use the RKE
or the driver door lock cylinder. Unlocking and
opening one of the other doors with the system
armed will trip the vehicle theft security system.
Interior monitoring is done by the use of an
Intrusion Sensor located in the front headliner and
with one or two sensors in the ceiling of the cargo
area depending on how the vehicle is equipped.
Monitoring of the interior of the vehicle will begin
after the system has been armed for 30 seconds. The
on/off switch located on the instrument panel can be
used to turn off this feature with the ignition switch
in either the Locked/Off or ACC position. The vehi-
cle tow-monitoring feature can also be switched off
using this switch. Re-locking the vehicle a second
time will reactivate these features.
If a trailer is connected to the vehicle when the
system is armed, the SSM will sense a resistance
change on the turn signal circuits if the trailer
harness becomes disconnected and will trip the
alarm.
Tripping the vehicle theft security system will
cause the hazard lamps to flash and the siren to
sound at 30-second intervals. The siren is equipped
with it's own self-contained battery. In the event the
vehicle's battery power is disconnected the siren
will continue to sound on it's own.

FLUID TYPES
DESCRIPTION
PARTS AND LUBRICANT RECOMMENDATIONS
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 1) on the label. At the bottom NLGI
symbol is the usage and quality identification letters.
Wheel bearing lubricant is identified by the letter
ªGº. Chassis lubricant is identified by the latter ªLº.
The letter following the usage letter indicates the
quality of the lubricant. The following symbols indi-
cate the highest quality.
When service is required, DaimlerChrysler Corpo-
ration recommends that only MOPARtbrand parts,
lubricants and chemicals be used. MOPARtprovides
the best engineered products for servicing
DaimlerChrysler Corporation vehicles.
AUTOMATIC TRANSMISSION FLUID - NAG1
NOTE: Refer to Service Procedures in this group for
fluid level checking procedures.
Use ATF approved to MB 236.10, MB 236.12, such
as Shell ATF 3403/M-115, MOPARtpart number
05127382AA, Fuchs/Shell ATF 3353, or equivalent.
Automatic Transmission Fluid (ATF) is red in color
when new. The ATF is dyed red so it can be identified
from other fluids used in the vehicle such as engine
oil or antifreeze. The red color is not permanent and
is not an indicator of fluid condition. As the vehicle is
driven, the ATF will begin to look darker in color and
may eventually become brown.This is normal.
FLUID ADDITIVES
DaimlerChrysler strongly recommends against the
addition of any fluids to the transmission, other than
those automatic transmission fluids listed above.
Exceptions to this policy are the use of special dyes
to aid in detecting fluid leaks.
Various ªspecialº additives and supplements exist
that claim to improve shift feel and/or quality. These
additives and others also claim to improve converter
clutch operation and inhibit overheating, oxidation,
varnish, and sludge. These claims have not been sup-
ported to the satisfaction of DaimlerChrysler and
these additivesmust not be used.The use of trans-
mission ªsealersº should also be avoided, since they
may adversely affect the integrity of transmission
seals.

(6) Start the engine in the vehicle which has the
booster battery, let the engine idle a few minutes,
then start the engine in the vehicle with the dis-
charged battery.
CAUTION: Do not crank starter motor on disabled
vehicle for more than 15 seconds, starter will over-
heat and could fail.
(7) Allow battery in disabled vehicle to charge to
at least 12.4 volts (75% charge) before attempting to
start engine. If engine does not start within 15 sec-
onds, stop cranking engine and allow starter to cool
(15 min.), before cranking again.
DISCONNECT CABLE CLAMPS AS FOLLOWS:
²Disconnect BLACK cable clamp from engine
ground on disabled vehicle.
²When using a Booster vehicle, disconnect
BLACK cable clamp from battery negative terminal.
Disconnect RED cable clamp from battery positive
terminal.
²Disconnect RED cable clamp from battery posi-
tive terminal on disabled vehicle.
TOWING
STANDARD PROCEDURE - TOWING
WARNING: Do not tow the vehicle if the key cannot
be turned in the ignition lock. If the key cannot be
turned, the ignition lock remains locked and the
vehicle cannot be steered. With the engine not run-
ning there is no power assistance for the braking
and steering systems. In this case, it is important to
keep in mind that a considerably higher degree of
effort is necessary to brake and steer the vehicle.
The vehicle must not be towed with the front axle
raised and the key in position 2 in the ignition lock
as the drive wheels could then lock due to the
acceleration skid control (ASR)
If the Engine is Damaged
For towing distances up to 30 miles (about 50
km)
²Shift selector lever in ªNº position.
²Do not exceed a towing speed of 30 m.p.h. (50
km/h).
For towing distances greater than 30 mile
(about 50 km)
²Remove the propeller shafts leading to the drive
axles. The vehicle can be towed without restriction.
If the Transmission is Damaged
²Remove the propeller shafts leading to the drive
axles. The vehicle can be towed without restriction.
If the Front Axle is Damaged
²Raise the front axle.
²Observe the same towing restrictions as for
engine damage.
If the Rear Axle is Damaged
²Raise the rear axle.
NOTE: Comply with local legal regulations regard-
ing towing vehicles.
SAFETY PRECAUTIONS
NOTE: The following safety precautions must be
observed when towing a vehicle.
²Secure loose and protruding parts.
²Always use a safety chain system that is inde-
pendent of the lifting and towing equipment.
²Do not allow towing equipment to contact the
disabled vehicle's fuel tank.
²Do not allow anyone under the disabled vehicle
while it is lifted by the towing device.
²Do not allow passengers to ride in a vehicle
being towed.
²Always observe state and local laws regarding
towing regulations.
²Do not tow a vehicle in a manner that could
jeopardize the safety of the operator, pedestrians or
other motorists.
²Do not attach tow chains, T-hooks, J-hooks, or a
tow sling to a bumper, steering linkage, drive shafts
or a non-reinforced frame hole.
²Remove exhaust pipe tips that interfere with the
tow sling and crossbar
²Padding should be placed between the tow sling/
crossbar and any painted surfaces
²When placing tow hooks on the rear axle, posi-
tion them so they do not damage the brake tubing or
hoses
²Do not tow the vehicle by connecting to the front
or rear shock absorbers
²Do not tow a heavily loaded vehicle. Damage to
the vehicle may result. Use a flatbed device to trans-
port a loaded vehicle.
GROUND CLEARANCE
CAUTION: If vehicle is towed with wheels removed,
install lug nuts to retain brake drums.
A towed vehicle should be raised until lifted wheels
are a minimum 100 mm (4 in) from the ground. Be
sure there is adequate ground clearance at the oppo-
site end of the vehicle, especially when towing over
rough terrain, steep rises in the road or if the vehicle
is equipped with air dams, spoilers, and/or ground
VALUBRICATION & MAINTENANCE 0 - 7

effect panels. If necessary, remove the wheels from
the lifted end of the vehicle and lower the vehicle
closer to the ground, to increase the ground clearance
at the opposite end of the vehicle. Install lug nuts on
wheel attaching studs to retain brake drums.
RAMP ANGLE
If a vehicle with flat-bed towing equipment is used,
the approach ramp angle should not exceed 15
degrees.
TOWING WHEN KEYS ARE NOT AVAILABLE
When the vehicle is locked and keys are not avail-
able, use a flat bed hauler. A Wheel-lift or Sling-type
device can be used provided all the wheels are lifted
off the ground using tow dollies.
MAINTENANCE SCHEDULES
DESCRIPTION
The use of special lubricant additives is not recom-
mended. The use of such additives may affect the
warranty rights. With regard to legal stipulations
concerning emissions control, please note that
engines have to be serviced and adjusted in accor-
dance with special instructions and using special
measuring equipment. Modifications to or interfer-
ence with the emissions control systems are not per-
missible.

SPECIAL MAINTENANCE REQUIREMENTS
If bodies built by manufacturers other than
DaimlerChrysler Corporation are fitted to the vehi-
cle, the maintenance requirements and lubrication
intervals specified by the body manufacturer must be
adhered to, in addition to all standard maintenance
requirements.
Coolant
Corrosion inhibitor/antifreeze concentration in the
coolant should be checked before the onset of winter
(once year in countries with high prevailing temper-
atures).
Replace the coolant every five years or 100,000
miles.
Dust Filter for Heating / Ventilation Replacement
The dust filter and the tailgate interior filter are to
be renewed during routine maintenance service. If
operating conditions are dusty, these filters should be
renewed more frequently.
ENGINE OIL CHANGE AND FILTER REPLACEMENT
At a minimum, change the engine oil and oil filter
once a year ± even if the vehicle mileage per year is
extremely low. For standard oil service schedules
refer to the chapter oil service and maintenance ser-
vice.
