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 lev-
els. 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.
The TPMS consists of the following components:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, a LOW TIRE PRESSURE
message and “Inflate Tire to XX” message will be dis-
played for a minimum of five seconds, and an audible
chime will be activated 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
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value. The recommended cold placard pressure value is
the pressure value in the Inflate Tire to XXmessage
displayed in the EVIC. The system will automatically
update and the Tire Pressure Monitoring Light will
extinguish and the LOW TIRE PRESSURE and “Inflate
Tire to XX” messages will turn off 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.

Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster and an audible chime will
be activated when one or more of the four active road tire
pressures are low. The audible chime will sound once
every ignition cycle for the first condition that it detects.
In addition, the EVIC will display a “Inflate Tire to XX”
message for a minimum of five seconds and a graphic of
the pressure value(s) with the low tire(s) flashing or
displayed in a different color. The recommended cold
placard pressure inflation value is the pressure value
displayed in theInflate Tire to XX message displayed in
the EVIC.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible
and inflate all tires that are flashing or in a different color
on the graphic display to the vehicle’s recommended cold placard pressure value. The system will automati-
cally update, the “Inflate Tire to XX” message will no
longer be displayed, the graphic display of the pressure
value(s) will stop flashing or return to their normal color,
and the Tire Pressure Monitoring Light will extinguish
once the updated tire pressure(s) 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.
Service TPMS Message
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. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This text
message is then followed by a graphic display, with “- -“
in place of the pressure value(s) indicating which Tire
Pressure Monitoring Sensor(s) is not being received.5

CAUTION!(Continued)
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.

CAUTION!
If the trailer weighs more than 1,000 lbs (450 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’s hydrau-
lic brake lines. It can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have a collision.
•Towing any trailer will increase your stopping dis-
tance. When towing, you should allow for additional
space between your vehicle and the vehicle in front of
you. Failure to do so could result in a collision.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four-pin and
seven-pin wiring harness. Use a factory approved trailer
harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s
wiring harness.
The electrical connections are all complete to the vehicle,
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Manual Transmission — If Equipped
If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in DRIVE, use the
AutoStick® shift control to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions, will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking. If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the trans-
mission fluid and filter as specified for severe usage
(police, fleet, taxi, or frequent trailer towing). Refer to the
Maintenance Schedule
for the proper maintenance in-
tervals.
AutoStick®
When using the AutoStick® shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose 4if
the desired speed can be maintained. Choose 3or2 if
needed to maintain the desired speed.
To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and road
conditions allow.

Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods, shift the transmission
into NEUTRAL and increase engine idle speed. Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

CAUTION!
•Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealer or qualified
repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at regular
intervals, such as every fuel stop. The best time to check the
engine oil level is about five minutes after a fully warmed
engine is shut off. Do not check oil level before starting the
engine after it has sat overnight. Checking engine oil level
when the engine is cold will give you an incorrect reading.
Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings. Maintain the oil level between the
range markings on the dipstick. The range markings will
consist of a crosshatch zone which depicts the MIN at the
low end of the range and MAX at the high end of the range.
Adding 1 qt (1L) of oil when the reading is at the low end
of the indicated range will result in the oil level at the full
end of the indicator range.
