Section 2 Features and Controls
2-1
Your vehicle has one
double-sided key for the
ignition and all door locks.
If you ever lose your key, your dealer will be able to
assist you with obtaining a new one.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you ever do get locked out of your vehicle, call GM
Roadside Assistance Center. SeeRoadside Assistance
Program on page 7-5.Remote Keyless Entry System
If equipped, the keyless entry system 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 modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
2-3
At times you may notice a decrease in range. This is
normal for any remote keyless entry 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” under
Remote Keyless Entry System Operation on
page 2-4.
•If you are still having trouble, see your dealer or a
qualified technician for service.
Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
To unlock the driver’s
door, press the UNLOCK
button one time.
If you press the button again within five seconds, all of
the doors will unlock. When the UNLOCK button is
pressed, the interior dome lamps are turned on for about
40 seconds or until the ignition switch is activated.
Press the LOCK button to lock all doors.
2-4
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry 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 remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. 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 remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.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.
1. Insert a thin object, such as a coin, into the slot
between the covers of the transmitter near the key
ring hole. Remove the bottom by twisting the object.
2. Remove and replace the battery, positive (+) side
down. Use one Panasonic
®type CR2032 battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter. If the
transmitter does not work after battery replacement,
it may need to be resynchronized to your vehicle.
SeeResynchronizationfollowing.
2-5
There are several ways to lock and unlock your vehicle.
If your vehicle is equipped with keyless entry, you
can use your transmitter to lock or unlock your vehicle.
SeeRemote Keyless Entry System Operation on
page 2-4.
To lock or unlock your door from the outside,
use your key.
To lock the door from the
inside, slide the manual
lever on the door down.
To unlock the door,
slide the manual lever up.Power Door Locks
If your vehicle has power
door locks, press the
bottom of the power door
lock switch to lock all
the doors at once.
To unlock all the doors at
once, press the top of
the power door lock switch.
When a door is locked, the inside door handle will
not work.
