Tire Pressure Monitoring System (Tpms) - Aston Martin DBX Owner's Handbook Manual

Park Brake Operation While Moving
Warning: Repeated use of the park brake to slow the
vehicle, or driving the vehicle with the park brake applied
can cause serious damage to the brake system.
In an emergency, push and hold the park brake switch to reduce
speed. The symbol will come on, a warning sound will be
heard and CAUTION PARK BRAKE APPLIED will be shown in the
right instrument cluster window.
Release the switch to cancel the park brake application whilst the
vehicle is moving. The park brake will only apply as normal once
the vehicle has stopped movement.
Park Brake Faults
Low Battery Voltage
If the battery voltage is too low, the park brake cannot be put on
or off. Connect an auxiliary battery if the battery voltage is too
low.
System Faults
If a fault in the system is detected, PARK BRAKE MALFUNCTION
will show in the message centre. Contact your nearest Aston
Martin Dealer.
If the battery has been discharged or disconnected, APPLY FOOT
AND PARK BRAKE will show in the message centre when the
ignition is next ON. Press the foot brake down and pull the park
brake switch up to put the park brake ON, this will reset the park
brake system.

Tire Pressure Monitoring System (TPMS)

As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle's
handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's responsibility to maintain
correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure telltale.
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer (Refer to 'Wheel and
Tire Information', page 11.15)on the vehicle placard or tire
inflation pressure label (Refer to 'Vehicle Loading', page 11.22).
(If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
