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 Limits 0 224. 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 MonitorSystem 0 296.
Fuel
Premium Recommended Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with an octane rating as
low as 87 may be used, but it will
reduce performance and fuel
economy. See Fuel 0 249.
E85 or FlexFuel
No E85 or FlexFuel
Gasoline-ethanol fuel blends greater
than E15 (15% ethanol by volume),
such as E85, cannot be used in this
vehicle.
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. Display REMAINING OIL LIFE
on the Driver Information
Center (DIC). See DriverInformation Center (DIC) 0 110.
2. Press and hold SET/CLR to
reset the oil life at 100%.
3. Turn the ignition to LOCK/OFF.

Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
Leaving children in a vehicle with
an ignition key or Remote
Keyless Entry (RKE) transmitter is
dangerous and children or others
could be seriously injured or
killed. They could operate the
power window or other controls or
make the vehicle move. The
windows will function with the key
in the ignition or with the RKE
transmitter in the vehicle, and
children or others could be caught
in the path of a closing window.
Do not leave children in a vehicle
with the ignition key or an RKE
transmitter.
impacted, and airbags may not
deploy. To reduce the risk of
unintentional rotation of the
ignition key, do not change the
way the ignition key and Remote
Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
Warning
{
If the key is unintentionally
rotated while the vehicle is
running, the ignition could be
moved out of the RUN position.
This could be caused by heavy
items hanging from the key ring,
or by large or long items attached
to the key ring that could be
contacted by the driver or
steering wheel. If the ignition
moves out of the RUN position,
the engine will shut off, braking
and steering power assist may be
(Continued)
The ignition key, key rings, and RKE
transmitter, if equipped, are
designed to work together. As a
system, it reduces the risk of
unintentionally moving the key out
of the RUN position. If replacements
or additions are required, see your
dealer. Limit added items to a few
essential keys or small, light items
no larger than an RKE transmitter.
Interference from radio-frequency
identification (RFID) tags may
prevent the key from starting the
vehicle. Keep RFID tags away from
the key when starting the vehicle.
The key that is part of the RKE
transmitter can be used for the
ignition and driver side lock.

Programming Keys to the
Vehicle
Only keys programmed to the
vehicle will work. If a key is lost or
stolen, a replacement can be
purchased and programmed through
your dealer. The vehicle can be
reprogrammed so that lost or stolen
keys no longer work. Any remaining
keys will need to be reprogrammed.
Each vehicle can have up to eight
keys matched to it.
Programming with two
Recognized Keys
To program a new key:
1. Insert the original, already
programmed key in the ignition
and turn the key to the ON/
RUN position.
2. Turn the key to LOCK/OFF,
and remove the key.
3. Quickly, within five seconds,
insert the second original
already programmed key in the
ignition and turn it to the ON/
RUN position.
4. Insert the new key to be
programmed and turn it to the
ON/RUN position within
five seconds.
The security light will turn off
once the key has been
programmed.
5. Repeat Steps 1–5 if additional
keys are to be programmed.
If a key is lost or damaged, see your
dealer to have a new key made.
Programming without two
Recognized Keys
Program a new key to the vehicle
when a recognized key is not
available. Canadian regulations
require that owners see their dealer.
If two currently recognized keys are
not available, follow this procedure
to program the first key.
This procedure will take
approximately 30 minutes to
complete for the first key. The
vehicle must be off and all of the
keys you wish to program must be
with you.
1. Insert the new vehicle key into
the ignition.
2. Turn to ON/RUN. The security
light will come on.
3. Wait 10 minutes until the
security light turns off.
4. Turn the ignition to LOCK/OFF.
5. Repeat Steps 2–4 two more
times. After the third time, turn
to ON/RUN; the key is learned
and all previously known keys
will no longer work with the
vehicle.
6. To learn the second key, turn to
OFF and insert the second key
to be learned and rotate to
ON/RUN.
After the two keys are learned,
remaining keys can be learned by
following the procedure in
“Programming with two
Recognized Keys.”
Battery Replacement
When replacing the battery, do
not touch any of the circuitry on
the transmitter. Static from your
body could damage the
transmitter.
The battery is not rechargeable. To
replace the battery:
1. Press the button on the
transmitter to extend the key.
Caution
2. Remove the battery cover by
prying it with a finger.
3. Remove the battery by pushing
on the battery and sliding it
toward the key blade.
4. Insert the new battery, positive
side facing up. Push the
battery down until it is held in
place. Replace with a CR 2032
or equivalent battery.
5. Snap the battery cover back on
to the transmitter.
If equipped, this feature allows the
engine to be started from outside
the vehicle.
/ : This button will be on the RKE
transmitter if the vehicle has remote
start.
The climate control system will use
the previous settings during a
remote start. The rear defogger and
heated seats may come on during
remote start based on cold ambient
conditions. See Heated Front Seats
0 49 and Vehicle
Personalization 0 113.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
require a person using remote start
to have the vehicle in view. Check
local regulations for any
requirements.
If the vehicle is low on fuel, do not
use the remote start feature. The
vehicle may run out of fuel.
Other conditions can affect the
performance of the transmitter. See
Remote Keyless Entry (RKE)
System 0 23.
Starting the Vehicle
To start the engine using the remote
start feature:
1. Press and release
2. Immediately after completing
Step 1, press and hold
least four seconds or until the
turn signal lamps flash. The
turn signal lamps flashing
confirms the request to remote
start the vehicle has been
received.
When the vehicle starts, the parking
lamps will turn on and remain on as
long as the engine is running. The
doors will be locked and the climate
control system may come on.
The engine will continue to run for
10 minutes unless a time extension
is done or the ignition is turned on.
After 30 seconds, repeat the steps if
Q.
/ for at
a 10-minute extension is desired.
Remote start can be extended
only once.
The key must be turned to ON/RUN
before driving.
Extending Engine Run Time
For a 10-minute extension, repeat
Steps 1 and 2 while the engine is
still running. An extension can be
requested 30 seconds after starting.
The remote start can be
extended once.
When the remote start is extended,
the second 10 minutes will start
immediately.
For example, if the engine has been
running for five minutes, and
10 minutes are added, the engine
will run for a total of 15 minutes.
A maximum of two remote starts,
or a single start with an extension,
is allowed between ignition cycles.
The vehicle's ignition must be
turned on and then back off before
the remote start procedure can be
used again.
To cancel a remote start, do one of
the following:
.
Press and hold
parking lamps turn off.
.
Turn on the hazard warning
flashers.
.
Turn the vehicle on and then off.

Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. 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.
