Universal Remote System
The Universal Home Remote System allows for garage
door openers, security systems, and home automation
devices to be programmed to work with these buttons in
the vehicle.
SeeUniversal Home Remote System
on page 3‑44.
Performance and Maintenance
Traction Control System (TCS)
The traction control system limits wheel spin. The
system turns on automatically every time the vehicle is
started.
.To turn off traction control, press and releaseiin
front of the shift lever.
Filluminates and the
appropriate DIC message is displayed. See DIC
Warnings and Messages on page 4‑55.
.Press and release the button again to turn on
traction control.
For more information, see Traction Control System
(TCS) on page 5‑6.
1-21

StabiliTrak®
The vehicle may have the StabiliTrak system that
assists with directional control of the vehicle in difficult
driving conditions. The system turns on automatically
every time the vehicle is started. The system cannot be
turned off.
For more information, seeStabiliTrak
®Systemon
page 5‑6.
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. If the warning light comes on, stop as soon as possible
and inflate the tires to the recommended pressure
shown on the tire loading information label located on
the driver side center pillar (B pillar). See
Loading the
Vehicle
on page 5‑19. The warning light will remain on
until the tire pressure is corrected.
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.
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 6‑66and
Tire Pressure Monitor Operation on page 6‑67.
1-22

Tire Sealant and Compressor Kit
This vehicle may come with a jack and spare tire or a
tire sealant and compressor kit. The kit can be used to
seal small punctures in the tread area of the tire.
SeeTire Sealant and Compressor Kit
on page 6‑82for
complete operating information.
Engine Oil Life System
The engine oil life system calculates engine oil life
based on vehicle use and 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.
Resetting the Oil Life System
1. Display the OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the DIC for more than five seconds. The oil life will change
to 100%.
See Engine Oil Life System on page 6‑20.
Fuel E85 (85% Ethanol)
Vehicles that have the 3.9L V6 engine (VIN Code M)
have a yellow fuel cap and can use either unleaded
gasoline or ethanol fuel containing up to 85% ethanol
(E85). See Fuel E85 (85% Ethanol)
on page 6‑8.
In all other engines, use only the unleaded gasoline
described under Gasoline Octane on page 6‑6.
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here are some
driving tips to get the best fuel economy possible.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods of time.
.When road and weather conditions are
appropriate, use cruise control, if equipped.
.Always follow posted speed limits or drive more
slowly when conditions require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same TPC
Spec number molded into the tire's sidewall near
the size.
.Follow recommended scheduled maintenance.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check that the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing its
job. See your dealer to have it repaired. Torn or frayed
safety belts may not protect you in a crash. They can rip
apart under impact forces. If a belt is torn or frayed, get
a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders
on page 4‑32for more
information.
Keep safety belts clean and dry. See Care of Safety
Belts
on page 6‑104.
Airbags

maintenance or replacement. Make sure the airbag
readiness light is working. See Airbag Readiness Light
on page 4‑33for more information.

or broken, the airbag may not work properly. Do not
open or break the airbag coverings. If there are any
opened or broken airbag covers, have the airbag
covering and/or airbag module replaced. For the
location of the airbag modules, see What Makes an
Airbag Inflate?
