In Brief 25
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits0200. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure. The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
0 283.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
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. Turn the ignition to ON/RUN, with the engine off.
2. Press the vehicle information button until OIL LIFE
REMAINING displays.
3. Press and hold the set/reset button until “100%”is
displayed. Three chimes sound
and the CHANGE ENGINE OIL
SOON message goes off.
4. Turn the key to LOCK/OFF. See
Engine Oil Life System 0249.
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.

Extending Engine Run Time
To extend the engine run time by
10 minutes, repeat Steps 1–2 while
the engine is still running. An
extension can be requested
30 seconds after starting. The
engine run time can only be
extended if it is the first remote start
since the vehicle has been driven.
Remote start can be extended
one time.
If the remote start procedure is used
again before the first 10-minute time
frame has ended, the first
10 minutes will immediately expire
and the second 10-minute time
frame will start.
For example, if
Qand then/are
pressed again after the vehicle has
been running for five minutes,
10 minutes are added, allowing the
engine to run for a total of
15 minutes.
A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles. After the vehicle's engine has been
started two times using the remote
start button, the ignition must be
turned on and then back off before
the remote start procedure can be
used again.
Canceling a Remote Start
To manually shut off a remote start:
.
Press and hold
/until the
parking lamps turn off.
. Turn on the hazard warning
flashers.
. Turn the ignition switch on and
then off.
Conditions in Which the
Remote Start Will Not Work
The vehicle cannot be started using
the remote start feature if the key is
in the ignition, the hood is open,
or there is an emission control
system malfunction.
The engine turns off during a remote
start if the coolant temperature gets
too high or if the oil pressure
gets low.
Door Locks
{Warning
Unlocked doors can be
dangerous.
. Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. When a
door is locked, the handle
will not open it. The chance
of being thrown out of the
vehicle in a crash is
increased if the doors are
not locked. So, all
passengers should wear
safety belts properly and the
doors should be locked
whenever the vehicle is
driven.
. Young children who get into
unlocked vehicles may be
unable to get out. A child
can be overcome by
extreme heat and can suffer
permanent injuries or even

Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. See Tire Messages 0137.
Stop as soon as possible, and inflate the tires to the pressure value
shown on the Tire and Loading
Information label. See
Tire Pressure
0 282.
When the Light Flashes First and
