2005 JEEP GRAND CHEROKEE service indicator

If the SKIS indicator light comes on during normal
vehicle operation (it has been running for longer than 10
seconds) a fault has been detected in the electronics and
the vehicle should be serviced as soon as possible.
NOTE:
•The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
•Mobil Speedpass™, additional Sentry Keys, or any
other transponder equipped components on the same
keychain will not cause a key-related (Transponder)
fault unless the additional part isphysically held
against the ignition keybeing used when starting the
vehicle. Also, cell phones, pagers, or other RF electron-
ics will not cause interference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Important Note About Service
A four digit PIN number is needed to service the Sentry
Key Immobilizer System. This number can be obtained
from your authorized dealer. However, this number can
also be found on your customer invoice that you were
given upon receipt of your vehicle.
Replacement Keys
NOTE:Only keys that have been programmed to the
vehicle electronics can be used to start the vehicle. Once
a Sentry Key has been programmed to a vehicle, it cannot
be programmed to any other vehicle.
At the time of purchase, the original owner is provided
with a four digit PIN number. This number is required
for dealer replacement of keys. Duplication of keys may
be performed at an authorized dealer or by using the
Customer Key Programming procedure. This procedure

consists of programming a blank key to the vehicle
electronics. A blank key is one which has never been
programmed.
NOTE:When having the Sentry Key System serviced,
bring all vehicle keys to the dealer.
Customer Key Programming
You can program new keys to the system if you have two
valid keys by doing the following:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds, a chimewill sound and the SKIS indicator light will begin to
flash. Turn the ignition switch OFF and remove the
second key.
4.
Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds, a single chime will sound. The SKIS indicator
light will stop flashing, turn on for 3 seconds; then turn off.
The new Sentry Key has been programmed. Repeat this
process to program up to a total of 8 keys.

14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If there is a fault present in the OCS, the “Airbag Warning
Light” (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The “Airbag Warning Light” is turned
on whenever there is fault that can affect the operation of
the airbag system. If there is a fault present in the OCS,
both the “PAD Indicator Light” and the “Airbag Warning
Light” are illuminated to show that the passenger airbag
is turned off until the fault is cleared. If an object is
lodged under the seat and interferes with operation of
the weight sensors, a fault will occur which turns on both
the “PAD Indicator Light” and the “Airbag WarningLight.” Once the lodged object is removed, the fault will
be automatically cleared after a short period of time.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity and occupant
size. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold
out of the way as the bags inflate to their full size. The
bags fully inflate in about 50–70 milliseconds. This is
about half of the time it takes to blink your eyes. The
bags then quickly deflate while helping to restrain the
driver and front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front

Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert you to
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs. (See
page 313 for more information.)
6. Airbag Warning Light
This light turns on and remains on for 6 to 8
seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible.7. Anti-Lock Brake Warning Light
This light monitors the Anti-Lock Brake System.
The light will turn on when the ignition switch is
turned to the ON position and may stay on for as long as
four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer.
