StabiliTrak is an
advanced comput-
er-controlled vehicle
stability and traction
enhancement sys-
tem that assists
with directional control of the vehicle in
difficult driving conditions. It turns on
automatically every time you start your
vehicle.To limit wheelspin and help
maintain directional control, you should
always leave the system on. However, if
your vehicle becomes stuck and rocking
the vehicle is required, the system
should be turned off.
To turn off the traction control part of the
system, press the (StabiliTrak) but-
ton located below the climate controls
on the instrument panel.
To turn off the traction control and stabil-
ity enhancement systems, press and
hold the button for five seconds.
StabiliTrak®– Stability Control
System (if equipped)
The Tire Pressure Monitor alerts you
when a significant reduction in pressure
occurs in one or more of your vehicle’s
tires by illuminating the (Low Tire
Pressure) warning light, which will remain
on until you correct the tire pressure. You
may also have a CHECK TIRE PRES-
SURE message appear on the DIC
(if equipped).
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must inflate the tire to
the proper tire pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label shows the
correct tire pressure for the tires when
they’re cold. “Cold” means your vehicle
has been sitting for at least three hours
or driven no more than one mile.
You can temporarily remove the DIC mes-
sage by acknowledging it with your DIC
controls. However, at the next vehicle
start-up, the DIC message will reappear if
the tire pressure has not been corrected.
During cooler conditions, the low tire
pressure warning light may appear when
the vehicle is first started and then turn
off as you start to drive. This could be
an early indicator that your tire pres-
sures are getting low and the tires need
to be inflated to the proper pressure.
See Section 5 of your Owner Manual.
Tire Pressure Monitor
Note:The Tire Pressure Monitor can alert
you about low tire pressure, but it doesn’t
replace normal monthly tire maintenance.
When the system is turned off, the
StabiliTrak light will illuminate.
See Section 4 of your Owner Manual.
To use this feature, move the shift lever
to the Manual (M) position and select a
lower or higher driving gear using the
+ / – button on the shift lever. The dis-
play on the instrument panel cluster will
show the current gear selection.
Press the – (minus) side of the button to
downshift. When slowing to a stop, the
vehicle will automatically downshift.
Press the + (plus) side of the button to
upshift. As vehicle speed increases, you
will need to manually upshift.
If current vehicle speed is too high or
too low for the requested gear, the shift
will not occur.
See Section 2 of your Owner Manual.

The Oil Life System calculates engine oil
life based on vehicle use and displays
CHANGE ENGINE OIL in the Driver
Information Center (DIC) when it’s nec-
essary to change your engine oil and
filter. The Oil Life System should be reset
to 100% only following an oil change.
Reset the Oil Life System using the DIC:
1. Turn on the ignition.
2. Press the (Vehicle Information)
button until the DIC displays OIL LIFE
REMAINING.
3. Press and hold the (Set/Reset)
button until 100% is displayed.
4. Turn off the ignition.
Reset the Oil Life System without the DIC:
1. Turn on the ignition, with the engine off.
2. Fully press and release the accelera-
tor pedal slowly three times within
five seconds.
3. If the CHANGE ENGINE OIL mes-
sage flashes, the system is reset;
otherwise, repeat the procedure.
4. Turn off the ignition.

Refueling the Vehicle
To open the fuel door, press the center-
rear edge of the door and it will pop

rear edge of the door until it latches and
is flush with the side of the vehicle.
See Section 5 of your Owner Manual.
Maximizing Fuel Economy
Your driving behavior is a big contributor
to your vehicle’s fuel economy.
Modifying your driving habits will
improve your fuel mileage. Here are
several fuel-saving tips:
• Combine short trips to minimize cold
engine starts, which reduce fuel
economy.
• Avoid quick starts and stops.
Accelerate moderately and drive at a
steady speed.
• Anticipate traffic flow and brake mod-
erately or coast.
• Use the air conditioning and defrost
modes only when necessary.
• Minimize electrical accessory opera-
tion by turning off items such as the
rear defogger and heated seats when
they are not needed.
• Use the remote start feature sparing-
ly. This feature turns the engine on,
consuming fuel at idle.
• Do not warm up the engine by idling.
Even on the coldest days, driving will
help the engine warm up faster.
• Selecting the AUTO feature on 4WD
models will be less economical than
2WD.
• Unload unnecessary cargo to reduce
the amount of weight in the vehicle.
• Regularly check and maintain proper
tire pressure.
• Maintain your vehicle. Regular main-
tenance will keep your vehicle run-
ning cleaner and more efficiently.
