Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Don’t drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or 6, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
306 STARTING AND OPERATING

Limited Use Spare — If Equipped
The limited use spare tire is for temporary emergency use
on your vehicle. This tire is identified by a limited use
spare tire warning label located on the limited use spare
tire and wheel assembly. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited use spare
tire affects vehicle handling. Since it is not the same tire,
replace (or repair) the original tire and reinstall on the
vehicle at the first opportunity.WARNING!
•The limited use spare tires are for emergency use
only. Installation of this limited use spare tire
affects vehicle handling. With this tire, do not
drive more than 50 mph (80 km/h). Keep inflated
to the cold tire inflation pressure listed on either
your tire placard or limited use spare tire and
wheel assembly. Replace (or repair) the original
tire at the first opportunity and reinstall it on your
vehicle. Failure to do so could result in loss of
vehicle control.
•Prolonged use of limited use spare, or incorrect
tire size of front wheel, may damage the transaxle
differential and result in loss of vehicle mobility
and could result in loss of vehicle control.
308 STARTING AND OPERATING

Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
an accident resulting in serious injury or death.
Use only the tire and wheel sizes with load ratings
approved for your vehicle.
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.

TIRE PRESSURE MONITOR SYSTEM (TPMS)
•
The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
•The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12 F (7 C). This means that when
the outside temperature decreases, the tire pressure
will decrease. 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 km) after
a three hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure
molded into the tire sidewall. Refer to the “Tires –
General Information” in this section for information
on how to properly inflate the vehicle’s tires. The tirepressure will also increase as the vehicle is driven - this
is normal and there should be no adjustment for this
increased pressure.
•The TPM System 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 and natural pressure loss through
the tire.
•The TPM System 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 placard pressure. Once the low
tire pressure warning (Tire Pressure Monitoring Tell-
tale Light) illuminates, you must increase the tire
pressure to the recommended cold placard pressure in
order for the Tire Pressure Monitoring Telltale Light to
turn off. The system will automatically update and the
Tire Pressure Monitoring Telltale Light will turn off
314 STARTING AND OPERATING

NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•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.
•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 pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the Tire Pressure Moni-
toring Telltale light.
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The Tire Pressure Monitor System (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 monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light
316 STARTING AND OPERATING

Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or
more of the four active road tires. 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 placard pressure
value. Once the system receives the updated tire pres-
sures, the system will automatically update and the Tire
Pressure Monitoring Telltale Light will turn off. 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.
Check TPMS Warning
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and then remain on solid when a
system fault is detected. The system fault will also sound
a chime. If the ignition key is cycled, this sequence willrepeat, providing the system fault still exists. The Tire
Pressure Monitoring Telltale Light will turn off when the
fault condition no longer exists. A system fault can occur
due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
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.

4. Trailer tongue weight rating for the trailer hitch
utilized (This requirement may limit the ability to
always achieve 10% of trailer tongue weight as a
percentage of total trailer weight).
Towing Requirements — Tires
•
Do not attempt to tow a trailer while using a compact
spare tire.
•Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to the
“Tires — General Information” in this section for
proper tire inflation procedures.
•Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
•Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires — General
Information” in this section for information on tread
wear indicators and for proper inspection procedure.
•When replacing tires, refer to “Tires — General Infor-
mation” in this section for information on replacement
tires and for proper tire replacement procedures. Re-
placing tires with a higher load carrying capacity will
not increase the vehicle’s GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
•
Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
•An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
