apply; See www.dtsc.ca.gov/hazardouswaste/
perchlorate.
1. If the key fob is equipped with a screw, remove the
screw. With the key fob buttons facing down, use a flat
blade (screwdriver) to pry the two halves of the trans-
mitter apart. Use extreme carenot to damage the seal or
internal components.
2. Remove and replace the batteries. Avoid touching the
new batteries with your fingers. Skin oils may cause

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:
•Does not come on during the six to eight seconds after
the ignition switch is first turned on.
•Remains on after the six to eight second interval.
•Comes on for any period of time while driving.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see the following list) in an event data recorder prior to the moment of airbag deployment, and up to a
quarter-second of high-speed deceleration data during
and/or after airbag deployment or near-deployment.
EDR data are ONLY recorded if an airbag deploys, or
nearly deploys, and are otherwise unavailable.
NOTE:
•Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete 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 perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.

Also, the rear cargo lamp may be turned on by pressing
the lens. Press the lens again to turn it off.When a door is open and the interior lights are on,
rotating the dimmer control all the way down to the OFF
detent will cause all the interior lights to turn off. This is
also known as the
Partymode because it allows the
doors to stay open for extended periods of time without
discharging the vehicle’s battery.

ELECTRICAL POWER OUTLETThis vehicle has two auxiliary power outlets that can
provide up to 20 Amps of current for accessories de-
signed for use with the standard power outlet adapters.
The outlet located in the lower portion of the instrument
panel has a snap-on plastic cap so that it can be covered
when not in use. As a safety precaution, the outlet in the
instrument panel only operates with the ignition switch
ON. When the optional cigar lighter heating element is
used, it heats when pushed in and pops out automati-
cally when ready for use.To preserve the heating
element, do not hold the lighter in the heating position.
The right side outlet is powered directly from the battery
(power available at all times). Items plugged into this
outlet may discharge the battery and/or prevent engine
starting. The left side outlet has power available only when the
ignition is on. This outlet will also operate a conventional
cigar lighter unit.
Power Outlets
116 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Electrical Outlet Use With Engine Off
WARNING!
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent engine
starting.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will degrade the battery
even more quickly. Only use these intermittently and
with greater caution.
• After the use of high-power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the alternator to
recharge the vehicle’s battery.
• Power outlets are designed for accessory plugs only.
Do not hang any type of accessory or accessory
bracket from the plug.
CUPHOLDERS
Front Cupholders
The front cupholders are located in the center console.
NOTE: The front cupholder insert is removable for
cleaning.

The defroster will automatically turn off after about ten
minutes. For five more minutes of operation, press the
switch again. To prevent excessive battery drain, use the
defroster only when the engine is operating.CAUTION!
Use care when washing the inside of the rear window
to prevent damage to heating elements. Use a soft
cloth and a mild washing solution, wiping parallel to
the heating elements. Also, keep all objects a safe
distance from the window to prevent damaging the
heating elements.

INSTRUMENT CLUSTER DESCRIPTION
Your vehicle is equipped with the instrument cluster
described on the following pages.
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank.
NOTE:When the ignition switch is turned to OFF, the
fuel gauge, voltmeter, oil pressure and temperature
gauges may not show accurate readings. When the
engine is not running, turn the ignition switch to ON to
obtain accurate readings.
2. Charging System Warning Light This light shows the status of the electrical charg-
ing system. The light should come on for three
seconds when the ignition is first turned ON. If the light
comes back on immediately or comes on while driving, it
means that there is a problem with the charging system
or the battery is low. Also, a chime will sound if the light
comes back on. See your authorized dealer immediately. 3. Front Fog Light Indicator Light — If Equipped
This light shows when the front fog lights are on.
4. Low Fuel Warning Light When the fuel level reaches approximately 2.8 gal
(10.6L) this light will turn on and a single chime
will sound.
5. Speedometer
Indicates vehicle speed.
6. Front Axle Lock Indicator Light — If Equipped Indicates when the front axle lock has been
activated.

If Engine Fails to Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
• Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be dan-
gerous if done improperly. Refer to Section 6 of
this manual for proper jump starting procedures
and follow them carefully.
Without Tip Start (Manual Transmission Only)
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while cranking the
engine. This should clear any excess fuel in case the
engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 Volt AC electrical outlet with a
grounded, three wire extension cord. The engine block
heater cord is found under the hood bundled in front of
the battery tray.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 Volt AC electrical cord could
cause electrocution.
Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.
MANUAL TRANSMISSION
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the vehicle,
especially on an incline.
CAUTION!
Never drive with your foot resting on the clutch
pedal, or attempt to hold the vehicle on a hill with the
clutch pedal partially engaged, as this will cause
abnormal wear on the clutch.
