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/
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.
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/deflation warning system
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. 706
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
calibration.
• Tyre chains
*
are used.
