Driver and Right Front Passenger Supplemental
Restraint System (SRS) - Airbag
This vehicle has front airbags for both the driver and
front passenger as a supplement to the seat belt restraint
systems. The driver’s airbag is mounted in the center of
the steering wheel. The passenger’s front airbag is
mounted in the instrument panel, above the glove com-
partment. The words SRS AIRBAG are embossed on the
airbag covers.
NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment.
The front airbags have a multistage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.
Also, the front passenger airbag is certified to the Federal
regulations that define Occupant Classification (refer to
information on Occupant Classification System in this
section).

How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC may
also modify the rate of inflation based on the occupant
size provided by the Occupant Classification Module.
The ORC will not detect roll over.
•The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.

Indicator Light and the Airbag Warning Light. Once the
lodged object is removed, the fault will be automatically
cleared after a short period of time.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
may be possible based on collision severity and occu-
pant size. The steering wheel hub trim cover and the
upper right side of the instrument panel separate and
fold out of the way as the bags inflate to their full size.
The bags fully inflate in about 50 - 70 milliseconds.
This is about half of the time it takes to blink your eyes.
The bags then quickly deflate while helping to restrain
the driver and front passenger. The driver’s front
airbag gas is vented through vent holes in the sides of
the airbag. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the Occupant Restraint Con-
troller (ORC). The ORC uses the occupant category to
determine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
•Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•TheSide Impact SRS Side Curtain Airbagare de-
signed to activate only in certain side collisions. When
the ORC (with side impact option) detects a collision
requiring the side curtain airbag to inflate, it signals
the inflators on the crash side of the vehicle. A quantity
of nontoxic gas is generated to inflate the side curtain
airbag. The inflating side curtain airbag pushes the
outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30

To Activate:
Push and release the speed control lever (“ON/
OFF”) once and the electronic speed control
indicator light in the instrument cluster will
illuminate indicating that the electronic speed
control is ON. To turn the system OFF, Push and release
the lever (“ON/OFF”) again and the system and indica-
tor will turn off.
To Set At A Desired Speed:
When the vehicle has reached the desired speed, pull the
lever toward you and release. Release the accelerator and
the vehicle will operate at the selected speed.
NOTE:Speed control will only function in third, fourth,
or fifth gear when in the Autostick Mode—if equipped.
NOTE:The speed control may not engage if a different
size tire is installed on one wheel, such as the compact
spare tire.
To Deactivate:
A soft tap on the brake pedal, pushing the lever away
from you (“CANCEL”) or normal braking while slowing
the vehicle will deactivate the speed control without
erasing the memory. Pushing and releasing the lever
(“ON/OFF”) or turning off the ignition erases the speed
memory.
To Resume Speed:
To resume a previously set speed, push the lever up and
release (“ACC/RES”). Resume can be used at any speed
above 20 mph (32 km/h).
To Vary the Speed Setting:
When the speed control is set, speed can be increased by
pushing the lever up and holding (“ACC/RES”). When
the lever is released, a new set speed will be established.
Pushing the lever up and releasing (“ACC/RES”) once
will result in a 1 mph (1.6 km/h) speed increase. Each
time the lever is pushed up and released, speed increases
so that pushing the lever up and releasing three times
will increase speed by 3 mph (4.8 km/h), etc.
120 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into Anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop),
•the clicking sound of solenoid valves,
•brake pedal pulsations,
•and a slight drop or fall away of the brake pedal at the
end of the stop.
These are all normal characteristics of ABS.
WARNING!
The Anti-Lock Brake System contains sophisticated
electronic equipment that may be susceptible to
interference caused by improperly installed or high
output radio transmitting equipment. This interfer-
ence can cause possible loss of anti-lock braking
capability. Installation of such equipment should be
performed by qualified professionals.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.

MULTI DISPLACEMENT SYSTEM (MDS) - 5.7L
Engine Only
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
ALL WHEEL DRIVE—IF EQUIPPED
This feature provides full time All Wheel Drive (AWD)
with Antilock Brake System (ABS)/Traction Control. The
front wheels provide 38% of the torque, and the rear
wheels provide 62% of the torque. The system is auto-
matic with no driver inputs or additional driving skills
required.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the front differential and/or
the transfer case.
SELF–SEALING TIRES—IF EQUIPPED
A non-hardening viscous sealant applied to the inner
liner of each tire fills punctures up to 0.19 in. (5 mm) to
minimize the loss of air pressure. This contributes to the
safety of the vehicle by significantly reducing the prob-
ability of a roadside stop due to a flat tire.

TIRE PRESSURE MONITOR SYSTEM—IF
EQUIPPED
Tire Pressure Monitoring—Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels (EXCLUDING THE SPARE
TIRE). Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver Module.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more
tire pressures is low. The Tire Pressure Monitoring Tell-
tale Light will flash on and off for 10 to 60 seconds when
a system fault is detected. The flash cycle will repeat
every ten minutes or until the fault condition is removed
and reset.The Tire Pressure Monitoring System consists of the
following components:
•Receiver Module
•4 Wheel Sensors
•Tire Pressure Monitoring Telltale Light
NOTE:For vehicles with optional wheel/tire sizes and
significantly different tire placard pressures, the placard
pressure value and the low-pressure threshold value is
re-programmable at your authorized dealer to accommo-
date the customer selected wheel/tire combinations rec-
ommended by DaimlerChrysler.
230 STARTING AND OPERATING
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to
the sensors may result.
CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the wheel rim sensor.
NOTE:
•
The TPMS can inform the driver of a low tire pressure
condition.
•The TPMS is not intended to replace normal tire care
and maintenance, nor to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
Tire Pressure Monitoring—Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure
readings to the Receiver Module. The wheel sensors
monitor tire pressure, and status for all four active road
tires.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
