period. The cold tire inflation pressure must not exceed the

maximum inflation pressure molded into the tire sidewall.

Refer to “Tires – General Information” in “Servicing And

Maintenance” for information on how to properly inflate

the vehicle’s tires. The tire pressure will also increase as the

vehicle is driven, this is normal and there should be no

adjustment for this increased pressure.

WARNING!

Many factors, such as vehicle loading, road conditions,

and driving conditions, influence the chance that

wheel lift or rollover may occur. ERM cannot prevent

all wheel lift or rollovers, especially those that involve

leaving the roadway or striking objects or other ve-

hicles. The capabilities of an ERM-equipped vehicle

must never be exploited in a reckless or dangerous

manner, which could jeopardize the user’s safety or the

safety of others.

The TPMS will warn the driver of a low tire pressure if the

tire pressure falls below the low pressure warning limit for

any reason, including low temperature effects, or natural

pressure loss through the tire.

5

The TPMS will continue to warn the driver of low tire

pressure as long as the condition exists, and will not turn

off until the tire pressure is at or above the recommended

cold tire pressure on the placard. Once the low tire pressure

warning (TPMS Warning Light) illuminates, you must

increase the tire pressure to the recommended cold tire

pressure in order for the TPMS Warning Light to turn off.

The system will automatically update and the TPMS

Warning Light will turn off once the system receives the

updated tire pressures. 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.

AUXILIARY DRIVING SYSTEMS

Tire Pressure Monitoring System (TPMS)

The Tire Pressure Monitor System (TPMS) will warn the

driver of a low tire pressure based on the vehicle recom-

mended cold tire pressure.

The tire pressure will vary with temperature by about 1 psi

(7 kPa) for every 12°F (6.5°C). This means that when the

outside temperature decreases, the tire pressure will de-

crease. Tire pressure should always be set based on cold

inflation tire pressure. This is defined as the tire pressure

after the vehicle has not been driven for at least three

hours, or driven less than 1 mile (1.6 km) after a three hour

122 SAFETY

For example, your vehicle may have a recommended cold

(parked for more than three hours) tire pressure of 30 psi

(207 kPa). If the ambient temperature is 68°F (20°C) and the

measured tire pressure is 27 psi (186 kPa), a temperature

drop to 20°F (-7°C) will decrease the tire pressure to

approximately 23 psi (159 kPa). This tire pressure is suffi-

ciently low enough to turn on the TPMS Warning Light.

Driving the vehicle may cause the tire pressure to rise to

approximately 27 psi (186 kPa), but the TPMS Warning

Light will still be on. In this situation, the TPMS Warning

Light will turn off only after the tires are inflated to the

vehicle’s recommended cold tire pressure value.

sensor to become inoperable. After using an after-

market tire sealant it is recommended that you take

your vehicle to an authorized dealership to have your

sensor function checked.

• After inspecting or adjusting the tire pressure, al-

ways reinstall the valve stem cap. This will prevent

moisture and dirt from entering the valve stem,

which could damage the Tire Pressure Monitoring

Sensor.

NOTE:

• The TPMS is not intended to replace normal tire care and

maintenance, or to provide warning of a tire failure or

condition.

CAUTION!

• The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures and

warnings have been established for the tire size

equipped on your vehicle. Undesirable system op-

eration or sensor damage may result when using

replacement equipment that is not of the same size,

type, and/or style. Aftermarket wheels can cause

sensor damage. Using aftermarket tire sealants may

cause the Tire Pressure Monitoring System (TPMS)

• The TPMS should not be used as a tire pressure gauge

while adjusting your tire pressure.

• Driving on a significantly under-inflated tire causes the

tire to overheat and can lead to tire failure. Under-

inflation also reduces fuel efficiency and tire tread life,

and may affect the vehicle’s handling and stopping

ability.

(Continued)

SAFETY 123

• The TPMS is not a substitute for proper tire mainte-

nance, and it is the driver’s responsibility to maintain

correct tire pressure using an accurate tire gauge, even if

under-inflation has not reached the level to trigger

illumination of the TPMS Warning Light.

The TPMS consists of the following components:

• Receiver Module.

• Four Tire Pressure Monitoring Sensors.

• Tire Pressure Monitoring System Warning Light.

Tire Pressure Monitoring Low Pressure Warnings

•

Seasonal temperature changes will affect tire pressure, and

the TPMS will monitor the actual tire pressure in the tire.

The Tire Pressure Monitoring System Warning Light will

illuminate in the instrument cluster, an acoustic signal will

be activated, and the “Check left or right front/rear tire”

text message will display when one or more of the four

active road tire pressures are low. Should this occur, you

should stop as soon as possible, check the inflation pres-

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

vehicle’s recommended cold placard pressure value. The

system will automatically update and the Tire Pressure

Monitoring Light will extinguish once the updated tire

pressures have been received. The vehicle may need to be

driven for up to 20 minutes above 15 mph (24 km/h) to

receive this information.

Base System

This is the TPMS warning indicator located in

the instrument cluster.

The TPMS uses wireless technology with wheel rim

mounted electronic sensors to monitor tire pressure levels.

Sensors, mounted to each wheel as part of the valve stem,

transmit tire pressure readings to the Receiver Module.

NOTE: It is particularly important for you to check the tire

pressure in all of the tires on your vehicle regularly and to

maintain the proper pressure.

124 SAFETY

Check TPMS Warnings

• If you install the compact spare tire in place of a road tire

that has a pressure below the low-pressure warning

limit, upon the next ignition cycle, a chime will sound

and the TPMS Warning Light will still turn ON due to

the low tire.

The TPMS Warning Light will flash on and off for 75 seconds

and remain on solid when a system fault is detected, an

audible chime will be activated and the “Service Tire Pressure

Monitoring System” text message will display. If the ignition is

cycled, this sequence will repeat providing the system fault

still exists. The TPMS Warning Light will turn off when the

fault condition no longer exists. A system fault can occur with

any of the following scenarios:

• However, after driving the vehicle for up to 20 minutes

above 15 mph (24 km/h), the TPMS Warning Light will

flash on and off for 75 seconds and then remain on solid.

• This occurs for each subsequent ignition cycle, a chime

will sound and the TPMS Warning Light will flash on

and off for 75 seconds and then remain on solid.

• Jamming due to electronic devices or driving next to

facilities emitting the same radio frequencies as the TPM

sensors.

• Once you repair or replace the original road tire and

reinstall it on the vehicle in place of the compact spare

tire, the TPMS will update automatically and the TPMS

Warning 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 (24 km/h) in order

for the TPMS to receive this information.

• Installing some form of aftermarket window tinting that

affects radio wave signals.

• Snow or ice around the wheels or wheel housings.

• Using tire chains on the vehicle.

• Using wheels/tires not equipped with TPM sensors.

NOTE: Your vehicle may be equipped with a compact

spare wheel and tire assembly.

• The compact spare tire does not have a tire pressure

monitoring sensor. Therefore, the TPMS will not monitor

the tire pressure in the compact spare tire.
