Battery Replacement
Under normal use, the batteries in your key chain
transmitter should last about two years.
You can tell the batteries are 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 batteries.
To replace the battery, insert the round end
of the door
lock key into the slot of the access door on the back of
the transmitter.
Turn
the door one-sixteenth of a turn to
the left, and'lift it out of the transmitter. Remove the
battery and replace it with a Sanyo CR2025 or
equivalent. It is important to use the correct size battery.
Using the wrong battery may damage the transmitter.
Make sure you install the battery as the direction under
the cover indicates.
To
put the cover back on, line up the
notches and turn to the right.
Theft
Vehicle theft is big business, especially in some cities.
Although your h i c k has a number of theft deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you can
help.
Key in the ignition: If you walk away from your
vehicle with the keys inside, it's an easy target for joy
riders or professional thieves
--
so don't do it.
When you park your Buick and open the driver's door,
you'll hear a tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transaxle. And remember to lock the doors.
