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. In addition, the EVIC will display
a “LOW TIRE PRESSURE” message for a minimum of
five seconds and a graphic showing the pressure values
of each tire with the low tire pressure values flashing or
in a different color. An Inflate to XXmessage will also be
displayed.
Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition (those
flashing or in a different color in the EVIC graphic) to the
vehicle’s recommended cold placard pressure inflation
value as shown in theInflate to XXmessage. Once the
system receives the updated tire pressures, the system
will automatically update, the graphic display in the

3. After driving the vehicle for up to 20 minutes above15 mph (25 km/h) the “Tire Pressure Monitoring
Telltale Light” will turn OFF and the pressure value
will be updated and stop flashing or return to it’s
original color, as long as no tire pressure is below the
low-pressure warning limit in any of the four active
road tires.

Failure to do so may cause you to lose control
resulting in an accident, causing serious or fatal
injury.
The TPMS tire light load inflation switch will allow the
driver to switch between the max load inflation pressure
(cold) low pressure warning threshold and the light load
inflation pressure (cold) low pressure warning threshold
depending on the vehicle’s load condition. The Tire and
Loading Information label defines the recommended
front and rear cold tire inflation pressures for the vehicle
when operating in the Max Load condition. A Supple-
mental Tire Pressure Information label is also available
defining Light Load tire inflation pressures when oper-
ating in the Light Load condition. When the tire light

thresholds.Tire Light Load Inflation Switch Operation – If
Equipped
•This vehicle may have different recommended tire
pressure values between the front and rear tires as
shown in both the Tire Loading Information Label and
the Supplemental Tire Pressure Information Label. It is
also equipped to be driven with tire pressures appro-
priate to either a Light Load condition or the vehicle
Max Load condition.
• The tire light load inflation switch will allow the driver
to change between the max load inflation pressure
(cold) low pressure warning threshold and the light
load inflation pressure (cold) low pressure warning
threshold depending on the vehicle’s load condition.
Refer to the “Supplemental Tire Pressure Information”
label for the vehicle’s Light Load inflation pressures
and “Tire and Loading Information” label for the
vehicle’s Max Load inflation pressures.
518 STARTING AND OPERATING

To switch from the max load inflation pressure (cold) low
pressure warning threshold to the light load inflation
pressure (cold) low pressure warning threshold, begin by
placing the ignition switch in the RUN position. Next,
lower all four road tire pressures to the Light Load
Inflation Pressure values as listed on the SupplementalTire Pressure Information label. The Supplemental Tire
Pressure Information label is located on the rear face of
the driver door opening. Use an accurate tire gauge to
check the tire pressures when lowering all four tire
pressures. The vehicle may need to be driven above
15 mph (25 km/h) to receive this updated pressure
information. After all four tire pressures have been
lowered to the Light Load inflation pressures, press the
tire light load inflation switch. If the tire light load
inflation switch’s amber colored LED turns ON, the
TPMS is using the light load inflation pressure (cold) low
pressure warning thresholds. A text message
Tire Pres-
sure System - Light Load Setting will also be displayed
in the EVIC.
If the tire light load inflation switch amber colored LED
flashes on and off for 10 seconds, after all four tire
pressures have been lowered to the Light Load inflation
pressures, the pressure in any one of the four tires may
not be at the light load inflation pressure (cold) values as

indicated for the Light Load condition as defined on the
Supplemental Tire Pressure Information label located on
the rear face of the driver door. A text messageCannot
Enter Light Load Setting - Please Adjust Tire Pressure
text message will also be displayed in the EVIC. Using an
accurate tire pressure gauge, re-check the tire pressures
for the light load inflation pressure (cold) value.
WARNING!
It is the driver ’s responsibility to change to the max
load inflation pressure (cold) low pressure warning
threshold condition when not driving in the light
load condition as defined as two occupants (150 lbs
[68 kg] each) plus 200 pounds (91 kg) of cargo. The
vehicle “Light Load Definition” is found in the
Supplemental Tire Pressure Information label lo-
cated on the rear face of the driver door. Failure to do
so may cause you to lose control resulting in an
accident, causing serious or fatal injury. To switch back to the max load inflation pressure (cold)
low pressure warning threshold, press the tire light load
inflation switch. It is not necessary to first fill the tires to
the max load inflation pressure (cold) values to switch
the TPMS system to the max load inflation pressure
(cold) low pressure warning threshold. If after pressing
the tire light load inflation switch, and tire pressures are
below the max load inflation pressure (cold) low pressure
warning thresholds, the “Tire Pressure Monitoring Tell-
tale Light” (located in the instrument cluster) will turn
ON and a chime will sound. An
inflate to XXmessage
will also be displayed. The tire pressures are now re-
quired to be inflated to the max load inflation pressure
(cold) values described on the Tire and Loading Informa-
tion label. The Tire and Loading Information label is
located on the drivers side B-pillar. If the tire light load
inflation switch LED turns OFF, the TPMS has been reset
and the TPMS is using the max load inflation pressure

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 weightvalues are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over the front and rear axle. Weigh-
ing the vehicle may show that the GAWR of either the
front or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier

WARNING!(Continued)
•Total 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
4. Trailer tongue weight rating for the trailer hitch
utilized .
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 “Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
• Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
• Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
• When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other thanyour authorized dealer, the message can be reset by refer-
ring to the steps described under “Electronic Vehicle Infor-
mation Center (EVIC)/Oil Change Required” in “Under-
standing Your Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering (2500/3500 Models
Only) and transmission as needed
• Check function of all interior and exterior lights
