the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. A system fault can
occur by any of the following scenarios:
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 affects ra-
dio 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.
6. Loss of communication with the trigger modules or
tire pressure monitoring sensors.
NOTE: Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the TPM Telltale Light will still turn ON due
to the low tire.
3. However, after driving the vehicle for up to 10 min-
utes above 15 mph (25 km/h), the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically and 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. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.
General Information
This device complies with part 15 of the FCC rules and
RSS 210 of Industry Canada. Operation is subject to the
following conditions:
²This device may not cause harmful interference.
²This device must accept any interference received, includ-
ing interference that may cause undesired operation.
The tire pressure sensors are covered under one of the
following licenses:

FUEL REQUIREMENTS
The 5.7L engine is designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high quality unleaded gasoline hav-
ing an octane range of 87 to 89. The manu-
facturer recommends the use of 89 octane
for optimum performance.The routine use
of premium gasoline is not recommended. The use of
premium gasoline will provide no benefit over high
quality regular and mid-grade gasolines, and in some
circumstances may result in poorer performance.
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.

SNOWPLOW
NOTE:Do not use this model vehicle for snowplow
applications.
WARNING!
Snowplows and other aftermarket equipment should
not be added to the front end or 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.Trailer Towing Position
