Tyre Pressure Monitoring System
The Tyre Pressure Monitoring System (TPMS) monitors the air pressure of all
four tyres. If the air pressure of one or more tyres is too low, the system warns the
driver by indicating the tyre pressure monitoring system warning light in the
instrument cluster and operating a beep sound.
In the following cases, system initialization must be performed so that the system
operates normally.
• A tyre pressure is adjusted.
• Tyre rotation is performed.
• A tyre or wheel is replaced.
• The battery is replaced or completely drained.
• The tyre pressure monitoring system warning
light is illuminated.
Diesel Particulate Filter
The diesel particulate filter collects and removes most of the particulate matter
(PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate filter is cleared during normal driving,
however, PM may not be removed and the diesel particulate filter indicator light
may illuminate under the following conditions:
• If the vehicle is driven at 15 km/h (9 mph) or less continuously.
• If the vehicle is repeatedly driven for a short period of time (10 minute or less)
or driven while the engine is cold.
• If the vehicle is idled for a long time.
For details, refer to Section 4, "Tyre Pressure Monitoring System" or
"Diesel Particulate Filter".
