• Please note that the TPMS is not a substitute for proper tire maintenance, and
it is the driver’s responsibility to maintain correct tire pressure, even if
under-inflation has not reached the level to trigger illumination of the TPMS low
tire pressure telltale.
• 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 combined with the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for approximately one minute and
then remain continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
• 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.
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 operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not use tire sealant from a
can, or balance beads if your vehicle is equipped with a TPMS, as damage to the
sensors may result.
- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on and a warning chime sounds while driving, safely pull over
and stop the vehicle. If the A/C system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle. If the temperature reading
does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will
occur. Have the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned
by steam or boiling coolant. You may want to call an authorized service center for
service if your vehicle overheats.
