How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch to the
“LOCK” position (vehicles without a smart entry & start system)
or off (vehicles with a smart entry & start system).
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (P. 518)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the engine switch to the “ON” position (vehicles without a
smart entry & start system) or IGNITION ON mode (vehicles with
a smart entry & start system).
Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks slowly 3 times.
■Situations in which the tire pressure warning system may not operate
properly (if equipped)
●This tire pressure warning system ensure a proper function when OE (Origi-
nal Equipment) tire is installed.
●In the following cases, the tire pressure warning system may not operate
properly.
• The vehicle uses non-standard size tires or tires made by other manufac-
turers.

• The vehicle uses snow tires, compact spare tire (if equipped) or tire
chains.
• The vehicle is being driven below approximately 40 km/h (25 mph).
• The vehicle is being driven on slippery or rough road surfaces.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.
