• Your vehicle has also been equipped with a TPMS malfunction indicatorto 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 each time the vehicle is restarted 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.
NOTE: Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C)
of air temperature change. Keep this in mind when checking tire pressure
inside a garage, especially in the Winter. Example: If garage temperature is
68°F (20°C) and the outside temperature is 32°F (0°C), then the cold tire
inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi
(7 kPa) for every 12°F (7°C) for this outside temperature condition.
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.
BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the
parking brake is not applied, it indicates a possible brake hydraulic
malfunction, brake booster problem or an Anti-Lock Brake System
problem.
• Please have your vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the
brake system may have failed. It will take longer to stop the vehicle.
You could have a collision. Have the vehicle checked immediately.
