TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Your vehicle will not have a spare tire and
will not use run-flat tires. The driver is solely
responsible to periodically check the tire
pressures. In case the user installs run-flat
tires on the vehicle, it falls under his/her
responsibility to make sure that the tires
are inflated to the correct pressure level to
prevent a TPMS malfunction.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is provided
by a separate telltale, which displays the
symbol “TPMS” when illuminated.
When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction telltale
after replacing one or more tires or wheels
on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
The TPMS is standard equipment in all
Karma vehicles. The following conditions
may trigger the warning light to turn on:
• Low pressure soft (80% of
recommended cold tire pressure)
• Low pressure hard (23.2 PSI)
• Fast pressure loss
• Low battery charge
The telltale icon will flash for 1 min
if there is a system malfunction,
then become stable until the malfunction is
corrected.
The CIU will display each sensor, showing
its corresponding wheel temperature and
pressure values.
TIRE PRESSURE CORRECTION
The tire pressure indicator light does not
automatically turn off when the tire
pressure is adjusted for all four tires. If the
condition that is causing the TPMS icon to
be illuminated is corrected, the vehicle
must be powered-down normally, then re-
energized and placed in System Ready
mode. If the TPMS module registers all
criteria as normal, the icon will go out.
If a TPMS sensor detects a problem and
the corrective action requires a repair or
tire replacement, the tire position can be
relearned manually.
With the vehicle in Park [P] and in System
Ready mode, you can enable the tire
learning feature in the CIU by selecting:
• Settings > Diagnostics> TPMS > Manual
Re-learn
Once learning is enabled, change the
pressure (either add air, or let some out) on
the corresponding tire. The system will
acknowledge the change in pressure with a
single short chirp. You must follow this
sequence:
• Front Left (FL), Front Right (FR), Rear
Right (RR), and Rear Left (RL)
Before moving to the next wheel, wait for
the system to issue a double chirp,
signaling each wheel has been identified
and the pressure value has been updated.
The corresponding turn indicator will flash
also. If for some reason the TPMS sensor
could not be communicated, or it times out,
a longer chime will sound, which means the
