uuWhen DrivinguDeflation Warning System  
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  
driver information interface.  
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.  
Deflation Warning System Initialisation  
Tyre pressure checked and inflated in:  
Warm weather can become under-inflated in  
colder weather.  
Cold weather can become over-inflated in warmer  
weather.  
You must start deflation warning system initialisation every time you:  
Adjust the pressure in one or more tyres.  
Rotate the tyres.  
The low tyre pressure/deflation warning system  
indicator will not come on as a result of over inflation.  
Replace one or more tyres.  
Before initialising the deflation warning system:  
Set the cold tyre pressure in all four tyres.  
2 Checking Tyres P. 707  
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. 707  
Make sure:  
The vehicle is at a complete stop.  
The adaptive cruise control (ACC)*, adaptive cruise  
control (ACC) with low speed follow (LSF)*, road  
departure mitigation, vehicle stability assist (VSA)  
system, vehicle stability assist (VSA) OFF, low tyre  
pressure/deflation warning system, collision  
mitigation braking system (CMBS), and parking brake  
and brake system (amber) indicators may come on in  
amber along with a message in the driver information  
interface when you turn the ignition switch to ON  
(w*1 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.

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.  
Tyre chains are used.

The low tyre pressure/deflation warning system  
indicator may come on under the following conditions:  
A compact spare tyre is used.  
There is a heavier and uneven load on the tyres,  
such as when towing a trailer, than the condition at  
initialisation.  
Tyre chains are used.

Deflation Warning System cannot be initialised if a  
compact spare tyre is installed.  
The initialisation process requires approximately 30  
minutes of cumulative driving at speeds between  
40-100 km/h (25-62mph).  
During this period, if the ignition is turned on and  
the vehicle is not moved within 45 seconds, you  
may notice the low tyre pressure indicator comes  
on briefly. This is normal and indicates that the  
initialisation process is not yet complete.  
Initialise, then press the ENTER button.  
u Completed screen appears, then the  
display returns to the customization  
menu screen.  
If the Failed message appears, repeat steps  
2-3.  
The initialisation process finishes  
automatically.  
If the tyre chains are installed, remove them before  
initialising the deflation warning system.  
If the low tyre pressure/deflation warning system indicator  
comes on even when the properly inflated specified regular  
tyres are installed, have the vehicle checked by a dealer.  
We recommend that the tyres be replaced with the  
same brand, model, and size as the originals. Ask a  
dealer for details.
