Remote Keyless Entry (RKE)
System
If the vehicle has the Remote Keyless Entry (RKE)
system, it operates on a radio frequency subject
to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.At times you may notice a decrease in range. This
is normal for any RKE system. If the transmitter
does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far
from your vehicle. You may need to stand
closer during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement”
underRemote Keyless Entry (RKE) System
Operation on page 92.
If you are still having trouble, see your
dealer/retailer or a qualied technician
for service.

Matching Transmitter(s) to Your
Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a
transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring
any additional transmitters so they can also be
re-coded to match the new transmitter. Once your
dealer has coded the new transmitter, the lost
transmitter will not unlock your vehicle. Each
vehicle can have a maximum of four transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about four years.
The battery is weak if the transmitter will not work at
the normal range in any location. If you have to get
close to your vehicle before the transmitter works, it
is probably time to change the battery.
The KEY FOB BATT LOW message in the vehicle’s
DIC will display if the RKE transmitter battery is low.
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static from
your body transferred to these surfaces may
damage the transmitter.To replace the battery in the RKE transmitter do
the following:
1. Insert a at object, with a thin edge, into the
notch located below the vehicle locator/panic
alarm button, and separate the bottom
half from the top half of the transmitter.
2. Remove the battery and replace it with the
new one. Make sure the positive (+) side of
the battery faces up. Use one three-volt,
CR2032, or equivalent, type battery.

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components.
If the ignition key is turned to the START
position, and then released when the engine
begins cranking, the engine will continue
cranking for a few seconds or until the vehicle
starts. If the engine does not start and the key
is held in START for many seconds, cranking
will be stopped after 15 seconds to prevent
cranking motor damage. To prevent gear
damage, this system also prevents cranking if
the engine is already running. Engine cranking
can be stopped by turning the ignition switch to
the ACC or LOCK position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor and holding it there as you
hold the key in START for up to a maximum of
15 seconds. Wait at least 15 seconds between
each try, to allow the cranking motor to cool
down. When the engine starts, let go of the key
and accelerator. If the vehicle starts briey but
then stops again, do the same thing. This
clears the extra gasoline from the engine.
Do not race the engine immediately after
starting it. Operate the engine and transaxle
gently until the oil warms up and lubricates all
moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.
