Transmitter Battery Service
NOTE: Perchlorate Material – special handling may
apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate
The recommended replacement battery is CR2032 bat-
tery. NOTE: Do not touch the battery terminals that are on
the back housing or the printed circuit board.
1. With the transmitter buttons facing down, remove the
small screw, and separate the two halves of the transmit-
ter. Make sure not to damage the rubber gasket during
removal.
2. Remove and replace the battery. Install the battery
with the positive terminal up, reference the note “+ SIDE
UP” on the inside of the bottom half of the transmitter
case. Avoid touching the new battery with your fingers.
Skin oils may cause battery deterioration. If you touch a
battery, clean it with rubbing alcohol.
3. To reassemble the transmitter case, join the two halves
of the case together. Install and tighten the screw until
snug. Make sure there is an even “gap” between the two
halves. Test transmitter operation.Transmitter Battery Replacement24 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

• The lap portion should be low on the hips and as snug
as possible.
• Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
NEW ENGINE BREAK-IN
5.7L Gas Engine
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
miles (500 km). After the initial 60 miles (100 km), speeds
up to 50 or 55 mph (80 or 90 km/h) are desirable. While
cruising, brief full-throttle acceleration, within the limits of local traffic laws, contributes to a good break-in.
Avoid wide open throttle acceleration in low gear.
The engine oil installed in the engine at the factory is a
high quality, energy conserving type lubricant. Oil
changes should be consistent with the anticipated cli-
matic conditions under which vehicle operation will
occur. The recommended viscosity and quality grades are
discussed in Section 7 under Maintenance Procedures,
Engine Oil.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
A new engine may consume some oil during its first few
thousand miles of operation. This is a normal part of the
break-in and is not an indication of difficulty.72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION!• During the first 500 miles (805 km) your new
vehicle is driven, do not tow a trailer. Doing so
may damage your axles, driveline and vehicle.
• Limit your speed to 50 mph (80 km/h) during the
first 500 miles (805 km) of towing.
6.7L Diesel Engine
Your Cummins 24 Valve Turbo Diesel engine does not
require a break-in period due to its construction. Normal
operation is allowed, provided the following recommen-
dations are followed:
NOTE: Light duty operation such as light trailer towing
or no load operation, will extend the time before the
engine is at full efficiency and may effect the performance
of the vehicle aftertreatment (exhaust) system. Reduced
fuel economy and power may be seen at this time. • 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 indica-
tors.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing or towing significant weight.
Because of the construction of the Cummins Diesel
engine, engine run-in is enhanced by loaded operating
conditions which allow the engine parts to achieve final
finish and fit during the first 6,000 miles (10 000 km). THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 73

Exhaust Gas
WARNING!Exhaust gases contain carbon monoxide, a poten-
tially toxic gas that by itself is colorless and odorless.
To avoid inhaling these gases, the following precau-
tions should be observed:
• Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
• If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
• The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system;
exhaust fumes detected inside the vehicle; or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
mispositioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust system
each time the vehicle is raised for lubrication or oil
change. Replace or adjust as required. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

Lights
Check the operation of all exterior lights. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching and locking. Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 77

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gages
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gages indicate a reading either too high or too low.
Examine the gages carefully, and follow the instructions
above for each indicated problem.
NOTE: When the ignition switch is turned to OFF, the
Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant
Temperature gages may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
NOTE:
• The voltmeter may show a gauge fluctuation if certain
engine temperatures are below 66°F (19°C). This cy-
cling operation is caused by the post-heat cycle of the
intake manifold heater system. The number of cycles
and the length of the cycling operation is controlled by
the engine control module, this time will not exceed
150 seconds. The needle should then stabilize at the
approximate operation point.
• The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.172 UNDERSTANDING YOUR INSTRUMENT PANEL

9. Oil Pressure Gauge
The pointer should always indicate some oil pres-
sure when the engine is running. A continuous
high or low reading, under normal driving conditions,
may indicate a lubrication system malfunction. Immedi-
ate service should be obtained. (See page 398 for more
information.)
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
10. Transfer Case Position
(See page 283 for more information.)
11 . TOW HAUL
The TOW HAUL button is located at the end of the gear
shift lever. This light will illuminate when the TOW
HAUL OD/OFF button is pushed once. (See page 271 for
more information.) 12. OD/OFF
the OD/OFF button is located at the end of the gear shift
lever. This light will illuminate when the TOW HAUL
OD/OFF button is pushed twice. (See page 271 for more
information.)
13. Temperature Gauge
The temperature gauge indicates engine coolant
temperature. Any reading within the normal
range indicates that the cooling system is operat-
ing satisfactorily. The gauge needle will likely indicate a
higher temperature when driving in hot weather, up
mountain grades, in heavy traffic, or when towing a
trailer. If the needle rises to the “245°F” mark, stop the
vehicle, shift into N (Neutral), and increase the engine
idle speed for 2 to 3 minutes. If the temperature reading
does not return to normal, shut your engine OFF and
allow it to cool. Seek authorized service immediately. See
Cooling System information in the section on “Maintain-
ing Your Vehicle.”174 UNDERSTANDING YOUR INSTRUMENT PANEL

23. Water In Fuel Indicator—Diesel Only
Indicates there is water detected in the fuel
filter. Refer to the Maintenance section, Drain-
ing Fuel/Water Separator Filter, for water
drain procedure. (See page 410 for more infor-
mation.)
24. Low Washer Fluid Light
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
25. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only)
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g. snow plowing, off- road operation). If this light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
26. Wait To Start Indicator—Diesel Only
The Wait To Start Indicator will illuminate when
the ignition is turned to the run position and the
ambient temperature is below 66 degrees F. Follow
engine starting procedure for proper engine starting and
operating. Wait until the Wait To Start Indicator turns
OFF then start the vehicle.
27. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.
28. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position. UNDERSTANDING YOUR INSTRUMENT PANEL 179

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
NOTE: On models equipped with Diesel engines, the
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions. UNDERSTANDING YOUR INSTRUMENT PANEL 241
