Jeep 2008 Liberty - Manual (Page 192)

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result. (Refer to
“Tire Inflation Pressures” under “Tires — General
Information” and to “Tire Pressure Monitor System
(TPMS)” in Section 5 of this manual for more
information).
5. Electronic Throttle Control (ETC) Warning Light —
If Equipped
This light informs you of a problem with the
Electronic Throttle Control system. If a problem
is detected, the light will turn on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable
and not need towing, however see your authorized
dealer for service as soon as possible.
If the light is flashing when the engine is running, you
may experience power loss, an elevated/rough idle, and
increased brake pedal effort, and your vehicle may
require towing. Immediate service is required.
The light will turn on when the ignition switch is first
turned ON, and remain on briefly as a bulb check. This is
normal. If the light does not turn on during starting, have
the system checked by an authorized dealer.
