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.

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:

This will cause the low tyre pressure/deflation
warning system indicator to come on and a
message to appear on the gauge.
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 overinflated in warmer
weather.
The low tyre pressure/deflation warning system
indicator will not come on as a result of overinflation.
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. 541
The indicators for the adaptive cruise control (ACC)
with low speed follow (amber), vehicle stability assist
(VSA) system, vehicle stability assist (VSA) OFF, low
tyre pressure/deflation warning system, and safety
support (amber) may come on along with a message
in the gauge after reconnecting the battery. Drive a
short distance at more than 20 km/h (12 mph). The
indicator should go off. If it does not, have your
vehicle checked by a dealer.
