Convenient Features
NOTICE
You can get a limp home password
when the vehicle is first delivered to
you. If you do not have a password,
consult your authorized HYUNDAI
dealer.
1. To activate the password, turn
the ignition key "ON" and "OFF"
according to the digit numbers. The
immobilizer indicator will blink along
with the operation of the ignition
key. For example, turn the ignition
key once for digit number "1", and
twice for "2", and so on. For the digit
number "0", you must cycle the
ignition key 10 times.
2. Wait for 3~10 seconds.
3. You may set the remaining number of
digits by following steps 1 and 2.
4. If all of the four password digits have
been successfully entered, turn the
ignition key "ON" and check that the
immobilizer indicator illuminates.
From this time, you have to start your
engine within 30 seconds. If you try
to start your engine after 30 seconds,
your engine will not start.
NOTICE
If the engine stalls while driving in the
"limp home" mode, you can start your
engine within 3 seconds without re-
entering the password.
5-12
If the immobilizer indicator blinks for five
seconds, you must re-enter the password
(steps 1~4).
After performing the limp home
activation procedure, consult with your
authorized HYUNDAI dealer as soon as
possible.
CAUTION
• If the password is entered incorrectly
three consecutive times, wait for
about one hour to perform the limp
home activation procedure again.
• If you cannot start your engine using
the limp home activation procedure,
have your vehicle towed by an
authorized HYUNDAI dealer.
