2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots 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.
NOTE:
•If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to
be ON, and a chime to sound. Driving the vehicle for
up to 20 minutes above 15 mph (25 km/h) will turnOFF the “Tire Pressure Monitoring Telltale Light” as
long as none of the road tires are below the low
pressure warning threshold.
•If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
If you install the 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 “Tire Pressure Monitoring Telltale Light” will
turn ON. After driving the vehicle for up to 20 minutes
above 15 mph (25 km/h), the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds
and then remain on solid. For each subsequent ignition
key cycle, a chime will sound and the “Tire Pressure
Monitoring Telltale Light” will flash on and off for
75 seconds and then remain on solid. Once you repair
or replace the original road tire, and reinstall it on the

vehicle in place of the spare tire, the TPMS will update
automatically and the “Tire Pressure Monitoring Tell-
tale 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 20 minutes above 15 mph (25 km/h)
in order for the TPMS to receive this information.

FUEL REQUIREMENTS
All engines are designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high quality unleaded “regular” gaso-
line having an octane rating of 87. The use
of premium gasoline is not recommended,
