sequence will repeat, providing the system fault still
exists. The TPMS Telltale Lamp will turn off when the
fault condition no longer exists. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:Your vehicle is equipped with a compact spare
wheel and tire assembly that does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored bythe TPMS. In the event that the compact spare tire is
swapped with a low pressure road tire, each ignition key
cycle will still show the TPMS Lamp to be ON, a chime to
sound, and a ª1 Tire Low Pressureº message to appear in
the EVIC. 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 Lamp 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) for the TPMS
to receive this information.
Premium TPMS ± If Equipped
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.
320 STARTING AND OPERATING

NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²3 Trigger Modules (mounted in three of the four wheel
wells)
²Various TPMS Messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and a
graphic displaying tire pressures.
²Yellow Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Telltale Lamp will illuminate in the instru-
ment cluster, and an audible chime will be activated
when one or more of the four active road tire pressures
are low. The EVIC will show a graphic display of the
pressure value(s) with the low tire(s) flashing.

no longer exists, the TPMS Telltale Light will no longerflash, theªSERVICE TIRE SYSTEM SOONºtext mes-

2. Installing some form of aftermarket window tinting

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels drive and steer the vehicle,
it is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to insure that it
is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle's
GVWR.
332 STARTING AND OPERATING

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
²When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
²Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
²Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. Always, block or9chock9the trailer wheels.
²GCWR must not be exceeded.
²Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
STARTING AND OPERATING 343

4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
Towing Requirements Ð Tires
þ
Do not attempt to tow a trailer while using a compact
spare tire.
þProper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to the
Tires±General Information section of this manual on
Tire Pressures for proper tire inflation procedures.
þAlso, check the trailer tires for proper tire inflation
pressures before trailer usage.
þCheck for signs of tire wear or visible tire damage
before towing a trailer. Refer to the Tires±General
Information section of this manual on Tread Wear
Indicators for the proper inspection procedure.
þWhen replacing tires refer to the Tires±General Infor-
mation section of this manual on Replacement Tires for
proper tire replacement procedures. Replacing tires
with a higher load carrying capacity will not increase
the vehicle's GVWR and GAWR limits.
Towing Requirements Ð Trailer Brakes
þ
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.
þAn 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.

Jacking Instructions
WARNING!
²Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. Never start
or run the engine while the vehicle is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
²The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
WARNING!
Carefully follow these tire changing warnings to help pre-
vent personal injury or damage to your vehicle:
²Always park on a firm, level surface as far from the edge
of the roadway as possible before raising the vehicle.
²Block the wheel diagonally opposite the wheel to be
raised.
²Apply the parking brake firmly before jacking.
²Never start the engine with the vehicle on a jack.
²Do not let anyone sit in the vehicle when it is on a jack.
²Do not get under the vehicle when it is on a jack.
²Only use the jack in the positions indicated.
²If working on or near a roadway, be extremely careful of
motor traffic.
²To assure that spare tires, flat or inflated are securely
stowed, spares must be stowed with the value stem
facing the ground.
