WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep Remote Keyless Entry key fobs away from
children. Operation of the Remote Start System,
windows, door locks or other controls could cause
serious injury or death.
ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due to
its construction. Normal operation is allowed, providing
the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine
lugging. •
Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying
or towing significant weight.
NOTE: Light duty operation such as light trailer towing or
no load operation will extend the time before the engine is
at full efficiency. Reduced fuel economy and power may be
seen at this time.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. The recom-
mended viscosity and quality grades are shown under
“Fluids, Lubricants and Genuine Parts”, under “Maintain-
ing Your Vehicle” in this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, both inside
and outside mirrors, and fasten your seat belts.
The starter is allowed to crank for up to 30-second inter-
vals. Waiting a few minutes between such intervals will
protect the starter from overheating.
WARNING!
•Before exiting a vehicle, always shift the automatic
transmission into PARK and apply the parking
brake. Always make sure the keyless ignition node is
in the “OFF” mode, remove the key fob from the
vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
(Continued)
WARNING! (Continued)
•Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
NOTE: Engine start up in very low ambient temperature
could result in evident white smoke. This condition will
disappear as the engine warms up.
CAUTION!
• The engine is allowed to crank as long as 30 seconds.
If the engine fails to start during this period, please
wait at least two minutes for the starter to cool before
repeating start procedure.

32 STARTING AND OPERATING
CAUTION!(Continued)
•If the “Water in Fuel Indicator Light” remains on,
DO NOT START engine before you drain the water
from the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
Normal Starting
Normal starting of either a warm or cold engine is obtained
without pumping or pressing the accelerator pedal. Turn
the key fob to the START position and release when the
engine starts. If the engine fails to start, turn the key fob to
the OFF position, wait five seconds, then repeat the “Nor-
mal Starting” procedure.
Automatic Transmission
Start the engine with the transmission gear selector in the
PARK position. Apply the brake before shifting to any
driving range.
Tip Start Feature
Do not press the accelerator. Cycle the ignition switch
briefly to the START position and release it. The starter
motor will continue to run but will automatically disen-
gage when the engine is running.
Keyless Enter-N-Go — Ignition
This feature allows the driver to operate
the ignition switch with the push of a
button, as long as the Remote Start/
Keyless Enter-N-Go key fob is in the
passenger compartment.
Normal Starting Procedure — Keyless Enter-N-Go
Observe the instrument panel cluster lights when starting
the engine.
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal
1. Always apply the parking brake.

WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
• When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, remove
the key fob from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
NORMAL OPERATION
Observe the following when the diesel engine is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Engine Oil Pressure telltale is not illuminated.
• Voltmeter operation:
The voltmeter may show a gauge fluctuation at various
engine temperatures. This is caused by the glow plug
heating system. The number of cycles and the length of the
cycling operation is controlled by the engine control mod-
ule. Glow plug heater operation can run for several min-
utes, once the heater operation is complete the voltmeter
needle will stabilize.

REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the key fob to start the engine
conveniently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
• The vehicle must be equipped with an automatic trans-
mission to be equipped with Remote Start.
• The Remote Start system will wait for the “Wait To Start”
telltale to extinguish before cranking the engine. This
allows time for the intake heater to pre-heat the incom-
ing air, and is normal operation in cold weather. Refer to
“Wait To Start” located in “Warning and Indicator
Lights” within “Understanding Your Instrument Panel”.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
• Transmission in PARK
• Doors closed
• Hood closed •
HAZARD switch off
• BRAKE switch inactive (brake pedal not pushed)
• Ignition key removed from ignition switch
• Battery at an acceptable charge level
• PANIC button not pushed
• Fuel meets minimum requirement
• Water In Fuel Indicator Light is not illuminated
• Wait To Start Light is not illuminated
WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep Remote Keyless Entry key fobs away from
children. Operation of the Remote Start System,
windows, door locks or other controls could cause
serious injury or death.
