Tire Pressure Monitoring Indicator Light
Yellow TelltaleLight What It Means
Tire Pressure Monitoring Indicator Light
The warning light switches on and a message is displayed to indicate that the tire pressure is
lower than the recommended value and/or that slow pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the indica-
tions corresponding to each tire in sequence.
IMPORTANT: Do not continue driving with one or more
flat tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. Repair im-
mediately using the dedicated tire repair kit and contact
your authorized dealership as soon as possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires. As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible and
inflate them to the proper pressure. Driving on a signifi-
cantly 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.

and Push Button to Start.
• Five Second Unstored Messages
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds and then returns to the previous screen. Examples of this
message type are
Memory System Unavailable - Not in
Park andAutomatic High Beams On.
The Reconfigurable Telltales section is divided into the
white telltales area on the right, amber telltales in the
middle, and red telltales on the left.
When the appropriate conditions exist, the Instrument
Cluster Display displays the following messages:
• Key In Ignition
• Ignition Or Accessory On
• Remote Start Aborted — Door Ajar
• Remote Start Aborted — Hood Ajar
• Remote Start Aborted — L/Gate Ajar
• Remote Start Aborted — Fuel Low
• Remote Start Disabled — Start Vehicle To Reset
• Remote Start Active — Push Start Button

340 STARTING AND OPERATING

Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side B-Pillar or rear edge of the driver’s side door.
At least once a month:
•Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual
judgement when determining proper inflation. Tires
may look properly inflated even when they are under-
inflated.
• Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pressure 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 sitting for a minimum of three hours. The
cold tire inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with tem-
perature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire inflation

CAUTION!(Continued)
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)
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 always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
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
gage, even if under-inflation has not reached the level to
trigger illumination of the “Tire Pressure Monitoring
Telltale Light.”
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Base System
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 your tires regularly and to maintain the
proper pressure.

•Vehicle Identification Number (VIN)
• Type of vehicle
• Month Day and Hour of Manufacture (MDH)
The bar code allows a computer scanner to read the VIN.
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 steer the vehicle, it is impor-
tant 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 a collision.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires must
be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial
scale before any occupants or cargo are added.
