Deflation Warning System - Honda JAZZ Owner's Manual

Deflation Warning System

Instead of directly measuring the pressure in each tyre, the deflation warning system
on this vehicle monitors and compares the rolling radius and rotational
characteristics of each wheel and tyre while you are driving to determine if one or
more tyres are significantly under-inflated. This will cause the low tyre pressure/
deflation warning system indicator to come on and a symbol to appear on the multi-
information display.
■
Deflation Warning System Calibration
You must start deflation warning system calibration every time you:
• Adjust the pressure in one or more tyres.
• Rotate the tyres.
• Replace one or more tyres.
Before calibrating the deflation warning system:
• Set the cold tyre pressure in all four tyres.
Make sure:
• The vehicle is at a complete stop.
Manual transmission models
• The parking brake is applied.
Continuously variable transmission models
• The shift lever is in P .

All models
• The ignition switch is in ON

uuWhen DrivinguDeflation Warning System
1Deflation Warning System
The system does not monitor the tyres when driving
at low speed.
Conditions such as low ambient temperature and
altitude change directly affect tyre pressure and can
trigger the low tyre pressure/deflation warning
system indicator to come on.
Tyre pressure checked and inflated in:
•
Warm weather can become under-inflated in
colder weather.
•
Cold weather can become over-inflated in warmer
weather.
The low tyre pressure indicator will not come on as a
result of over inflation.
The deflation warning system may not function
properly if tyre type and size are mixed.
Make sure to use the same size and type of tyre.
2 Checking and Maintaining Tyres P. 508
The low tyre pressure/deflation warning system
indicator may come on with a delay or may not come
on at all when:
•
You rapidly accelerate, decelerate, or turn the
steering wheel.
•
You drive on snowy or slippery roads.
•
Snow chains are used.
The low tyre pressure/deflation warning system
indicator may come on under the following conditions:
•
A compact spare tyre
•
There is a heavier and uneven load on the tyres,
such as when towing a trailer, than the condition at
calibration.
•
Snow chains are used.
