PRECAUTION

1. IGNITION SWITCH EXPRESSIONS

(a) The type of ignition switch used on this model differs according to the specifications of the vehicle. The expressions listed in the table below are used in this section.

2. TIRE PRESSURE WARNING SYSTEM PRECAUTION

(a) It is necessary for the tire pressures to be adjusted periodically because tire pressure decreases naturally over time.

(b) In winter, tire pressure may decrease due to low ambient temperatures (tire pressure decreases by approximately 10 kPa (0.1 kgf/cm², 1.5 psi) for every 10°C (18°F) drop in the ambient temperature). Therefore, the tire pressure warning system is more likely to indicate a warning if the tire pressures are not adjusted appropriately. If the daily temperature variation is large, add enough so that the tire pressures are suitable under cold conditions. As a result, unnecessary tire pressure warning operation should decrease.

(c) Depending on the tire type, the system may not function properly even if the specified wheels are used.

(d) To prevent damage to the tire pressure warning valve and transmitter, make sure that the tire pressure warning valve and transmitter does not interfere with the tire bead when installing or removing a tire.

(e) To prevent damage to the tire pressure warning valve and transmitter, before disengaging the tire bead or removing the tire from the wheel, drop the tire pressure warning valve and transmitter into the wheel.

(f) Always use a new grommet, washer and nut when installing a tire pressure warning valve and transmitter.

(g) When one or more tire pressure warning valve and transmitters or the tire pressure warning ECU is replaced, the transmitter IDs for all of the tire pressure warning valve and transmitters must be re-registered. Before registering the transmitter ID of the new tire pressure warning valve and transmitter, check the Data List and record all of the transmitter IDs that are already registered.
