A tire pressure monitoring sensor is located in the spare

wheel if the vehicle is equipped with a matching full size

spare wheel and tire assembly. The matching full size spare

tire can be used in place of any of the four road tires.

The “Tire Pressure Monitoring Telltale Light” will

illuminate in the instrument cluster, and an au-

dible chime will be activated when one or more of

the four active road tire pressures are low. The audible

chime will sound once every ignition cycle for each

condition that it detects. Should this occur, you should

stop as soon as possible, check the inflation pressure of

each tire on your vehicle, and inflate each tire to the

vehicle’s recommended cold tire pressure. The system

will automatically update and the “Tire Pressure Moni-

toring Light” will extinguish once the updated tire pres-

sures have been received. The vehicle may need to be

driven for up to 10 minutes above 15 mph (24 km/h) to

receive this information. A low spare tire will not cause

the “Tire Pressure Monitoring Telltale Light” to illumi-

nate or the chime to sound.

The “Tire Pressure Monitoring Telltale Light” will flash

on and off for 60 seconds, and an audible chime will

sound when a system fault is detected. The flash cycle

will repeat every ten minutes, without an audible chime,

until the fault condition no longer exists. If the ignition

key is cycled, this sequence will repeat, providing the

system fault still exists.

NOTE: If your vehicle is equipped with a matching full

size spare tire, 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 10 minutes above 15

mph (24 km/h) will turn OFF the “Tire Pressure Moni-

toring Telltale Light” as long as the spare tire or any other

road tire(s) are not below the low pressure warning

threshold.
