Failure to use driver and passenger seat beltsprovided
is a major cause of severe or fatal injury. In fact, the U.S.
government notes that the universal use of existing seat
belts could cut the highway death toll by 10,000 or more
each year, and could reduce disabling injuries by 2million annually. In a roll over crash an unbelted person
is significantly more likely to die than a person wearing
a seat belt. Always buckle up.
This manual has been prepared with the assistance of
service and engineering specialists to acquaint you with
the operation and maintenance of your new vehicle. It is
supplemented by a Warranty Information Booklet and
various customer oriented documents. You are urged to
read these publications carefully. Following the instruc-
tions and recommendations in this manual will help
assure safe and enjoyable operation of your vehicle.
NOTE: After you read the manual, it should be stored
in the vehicle for convenient reference and remain with
the vehicle when sold so that the new owner will be
aware of all safety warnings.

Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
²Does not come on during the 6 to 8 seconds after the
ignition switch is first turned on.
²Remains on after the 6 to 8 second interval.
²Comes on for any period of time while driving.
Event Data Recorder (EDR)
In the event of an airbag deployment, your vehicle is
designed to record up to 2-seconds of specific vehicle
data parameters (see list below) in an event data recorder
prior to the moment of airbag deployment. Please note
that such data are ONLY recorded if an airbag deploys,
and are otherwise unavailable. In conjunction with otherdata gathered during a complete accident investigation,
the electronic data may be used by DaimlerChrysler
Corporation and others to learn more about the possible
causes of crashes and associated injuries in order to
assess and improve vehicle performance. In addition to
crash investigations initiated by DaimlerChrysler Corpo-
ration, such investigations may be requested by custom-
ers, insurance carriers, government officials, and profes-
sional crash researchers, such as those associated with
universities, and with hospital and insurance organiza-
tions.
In the event that an investigation is undertaken by
DaimlerChrysler Corporation (regardless of initiative),
the company or its designated representative will first
obtain permission of the appropriate custodial entity for
the vehicle (usually the vehicle owner or lessee) before
accessing the electronic data stored, unless ordered to
download data by a court with legal jurisdiction (i.e.,
pursuant to a warrant). A copy of the data will be

12. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat andcan lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle's
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver 's responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
13. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

CD/DVD DISC MAINTENANCE
To keep the CD/DVD discs in good condition, take the
following precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper, paper CD labels, or tape to the
disc; avoid scratching the disc.
4. Do not use solvents such as benzine, thinner, cleaners,
or antistatic sprays.
5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being On in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily ªclearº by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
