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
message to appear on the gauge.
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.
2 Checking Tyres P. 650
Make sure:
• The vehicle is at a complete stop.
• The transmission is in
(P.
• The power mode is in ON.
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. 650
The Vehicle Stability Assist (VSA) system, Adaptive
Cruise Control (ACC) with Low Speed Follow, brake
system (amber), safety support, and low tyre
pressure/deflation warning system indicators may
come on in amber along with a message in the driver
information interface when you set the power mode
to ON after reconnecting the battery.
Drive a short distance at more than 20 km/h
(12 mph). Each indicator should go off. If any do not,
have your vehicle checked by a dealer.
