between the covers of the transmitter housing near
the key ring hole. Remove the bottom by twisting
the coin.

Resynchronization may be necessary due to the
security method used by this system. The transmitter

receiver will not respond to a signal that has been
sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the lock and unlock
buttons on the transmitter at the same time for
15 seconds. The door locks should cycle to conrm

H(4HI Lock):Use this mode when you need extra
traction in most off-road situations such as sand, mud,
snow or level, rocky trails.
I(4LO Lock):This mode delivers extra torque to all
four wheels and is used for extreme off-road conditions.
You might choose 4LO Lock if you are driving off-road,
