Tire Pressure Monitor
This vehicle may have a Tire Pressure Monitor
System (TPMS).
The Tire Pressure Monitor
alerts you when a
significant reduction in
pressure occurs in one or
more of the vehicle’s tires
by illuminating the low tire
pressure warning light on
the instrument cluster.
The warning light will remain on until the tire pressure is
corrected. The proper tire pressures for your vehicle are
listed on the Tire and Loading Information label located
on the driver side center pillar (B pillar). See Loading
the Vehicle
on page 5‑31. You may notice during cooler conditions that the low tire
pressure warning light will appear when the vehicle is
first started and then turn off as you drive. This may be
an early indicator that your tire pressures are getting
low and the tires need to be inflated to the proper
pressure.
Note:
The Tire Pressure Monitor can alert you about
low tire pressure, but it does not replace normal monthly
tire maintenance. It is the driver ’s responsibility to
maintain correct tire pressures.
See Tire Pressure Monitor System
on page 6‑73and
Tire Pressure Monitor Operation on page 6‑74.
Engine Oil Life System
The engine oil life system calculates engine oil life
based on vehicle use and, on most vehicles, displays a
DIC message when it is necessary to change the
engine oil and filter. The oil life system should be reset
to 100% only following an oil change.

CHECK TRAILER WIRING
On vehicles with the Integrated Trailer Brake Control
(ITBC) system, this message may display and a chime
may sound when one of the following conditions exists:
.A trailer with electric brakes becomes
disconnected from the vehicle.
‐If the disconnect occurs while the vehicle is
stopped, this message clears itself after a
short time.
‐ If the disconnect occurs while the vehicle is
moving, this message stays on until the ignition
is turned off.
.There is a short in the wiring to the electric trailer
brakes.
When this message displays, power is no longer
available to the trailer brakes.
As soon as it is safe to do so, carefully pull your vehicle
over to the side of the road and turn the ignition off.
Check the wiring connection to the trailer and turn the
ignition back on. This message clears if the trailer is
reconnected. This message also clears if you
acknowledge it. If this message still displays, either
your vehicle or the trailer needs service. See your
dealer/retailer.
See “Integrated Trailer Brake Control System” under
Towing a Trailer
on page 5‑42for more information.
4-58

At the same time a message to check the pressure in a
specific tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and
the DIC warning message come on at each ignition
cycle until the tires are inflated to the correct inflation
pressure. Using the DIC, tire pressure levels can be
viewed by the driver. For additional information and
details about the DIC operation and displays seeDIC
Operation and Displays (Using Trip Odometer Reset
Stem)
on page 4‑44or DIC Operation and Displays
(Using DIC Buttons)on page 4‑48and DIC Warnings
and Messages on page 4‑57.
The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then turn
off as you start to drive. This could be an early indicator
that the air pressure in the tire(s) are getting low and
need to be inflated to the proper pressure. A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle's original
equipment tires and the correct inflation pressure for
your vehicle's tires when they are cold. See
Loading the
Vehicle
on page 5‑31, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also see Inflation - Tire Pressure on page 6‑71.
Your vehicle's TPMS can warn you about a low tire
pressure condition but it does not replace normal tire
maintenance. See Tire Inspection and Rotation
on
page 6‑78and Tires on page 6‑62.
Notice: Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.
6-75

Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation
on page 6‑74.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications
on page 6‑122.
{WARNING:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the
vehicle. In an emergency, you can use a
cloth or a paper towel to do this; but be sure
to use a scraper or wire brush later,
if needed, to get all the rust or dirt off. See
Changing a Flat Tire
on page 6‑86.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, tighten the cable. See Storing a Flat or
Spare Tire and Tools
on page 6‑100.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions,
influence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which appear
when your tires have only
1/16 inch (1.6 mm) or less
of tread remaining. Some
commercial truck tires
may not have treadwear
indicators.
6-79

Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). SeeTire Inspection
and Rotation on page 6‑78.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑18. An Emission Control Service.
When the Change Engine Oil Soon message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset. Your
dealer/retailer has trained service technicians who will
perform this work and reset the system. If the engine oil
life system is reset accidentally, service the vehicle
within 5 000 km/3,000 miles since the last service. Reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 6‑20. When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
The services described for Maintenance
Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be
performed when:
.Maintenance Iwas performed the last time the
engine oil was changed.
