turn off. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
Check TPMS Warning
If a system fault is detected, the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
EVIC will display aCHECK TPM SYSTEM message for
three seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.

STARTING AND OPERATING 437

If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the TPM Telltale Light will no longer
flash, and theCHECK TPM SYSTEM message will no
longer display, and a pressure value will display in place
of the dashes. A system fault can occur due to any of the
following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors. Vehicles With Full Size Spare
1. The matching full size spare wheel and tire assembly
has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, a chime will sound
and the TPM Telltale Light will turn ON. In addition, the
EVIC will display a low pressure message and a graphic
showing the low tire pressure value flashing.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h) the TPM Telltale Light will turn OFF,
as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires.

FUEL REQUIREMENTS
3.7L and 4.7L Engine
These engines are designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high quality unleaded “regular”
gasoline having an octane rating of 87. The use of premium gasoline is not recommended, as it will
not provide any benefit over regular gasoline in these
engines.
5.7L Engine
This engine is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high quality unleaded gasoline having
an octane range of 87 to 89. The manufac-
turer recommends the use of 89 octane for
optimum performance. The use of premium gasoline is
not recommended, as it will not provide any benefit over
regular gasoline in these engines.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such

SNOWPLOW
1500 Models Only
NOTE: Do not use this model vehicle for snowplow
applications.
WARNING!
Snowplows and other aftermarket equipment should
not be added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in
the front end structure. The airbags could deploy
unexpectedly or could fail to deploy during a colli-
sion resulting in serious injury or death.
CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.
Do not expect that the airbag will perform as de-
scribed earlier in this manual
2500/3500 Models Only
Snowplow Prep Packages are available as a factory
installed option. These packages include components
necessary to equip your vehicle with a snowplow.
NOTE: Before installation of a snowplow it is highly
recommended that the owner/installer obtain and follow
the recommendations contained within the current Body
474 STARTING AND OPERATING

Operating Tips
Under ideal snow plowing conditions, 20 mph (32 km/h)
should be maximum operating speed. The operator
should be familiar with the area and surface to be
cleaned. Reduce speed and use extreme caution when
plowing unfamiliar areas or under poor visibility.
NOTE:During snowplow usage on vehicles equipped
with outside temperature display, the display may show
higher temperatures than the outside ambient tempera-
ture. The higher displayed temperature is due to blocked
or reduced airflow to the underhood ambient tempera-
ture sensor caused by the snowplow. In addition, on
vehicles equipped with Automatic Temperature Control
(ATC), it is suggested that the interior cabin temperature
be manually controlled should the system not perform as
desired while in automatic mode. Both the outside tem-
perature display and ATC operation will return to nor-
mal when the snowplow is removed.
General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer’s instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and drivetrain
damage, the following precautions should be observed.
•Operate with transfer case in 4L when plowing small or
congested areas where speeds are not likely to exceed
15 mph (24 km/h). At higher speeds operate in 4H.
•Vehicles with automatic transmissions should use 4L
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
•Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.

CAUTION!
•When installing the totally integrated power mod-

properly positioned and fully latched. Failure to
do so may allow water to get into the totally
