Ambient Temperature; Tire Pressure Monitoring - Aston Martin DB 9 2010 Manual

• Neutral, Park or Reverse gear positions are selected
• The difference between the actual and set speed is too great
• When the set speed is above 90 mph (144 km/h); Cruise Control
will disengage automatically after approximately 20 minutes
• The accelerator pedal is used to accelerate beyond the set speed
for too long a period

Ambient Temperature

The ambient temperature (outside temperature) is shown in the top
right corner of the Infotainment centre display.
If the vehicle has been travelling a while and then is stopped in a
shaded or enclosed area the ambient temperature may rise, this is
due to the heat from the engine bay. The ambient temperature
display will show the true ambient temperature once the vehicle is
moving again or the engine bay cools down.
If required the display units can be changed from °C to °F or °F
to °C (Refer to 'Display Units', page 7.7)

Tire Pressure Monitoring

Warning: Tire pressure monitoring is not intended to replace
driver awareness of tire performance or the need for
recommended weekly checks on tire condition and pressure.
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard or
tire inflation pressure label (if your vehicle has tires of a different size
than the size shown on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for
those tires).
As an added safety feature, your vehicle has been equipped with a
Tire Pressure Monitoring System (TPMS) that sets a low tire pressure
telltale to ON (Refer to 'Tire Pressure', page 4.7) when one or more
of your tires is significantly under-inflated.
