Buick Envista 2025 - Tire Pressure Monitor System

Buick Envista Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-18181221) - 2025
222 Vehicle Care
The Tire and Loading Information label
o
n the vehicle indicates the original
equipment tires and the correct cold tire
inflation pressures. The recommended
pressure is the minimum air pressure
needed to support the vehicle's maximum
load carrying capacity. See Vehicle Load
Limits 3141.
How the vehicle is loaded affects vehicle
handling and ride comfort. Never load
the vehicle with more weight than it was
designed to carry.
When to Check
Check the pressure of the tires once
amonth or more. Do not forget the spare,
if the vehicle has one. The compact spare
cold tire pressure should be at 420 kPa (60
psi). See Compact Spare Tire 3238.
How to Check
Use agood quality pocket-type gauge to
check tire pressure. Proper tire inflation
cannot be determined by looking at the
tire. Check the tire inflation pressure when
the tires are cold, meaning the vehicle has
n
ot been driven for at least three hours or
no more than 1.6 km (1 mi).
Remove the valve cap from the tire valve
stem. Press the tire gauge firmly onto the
valve to get apressure measurement. If
the cold tire inflation pressure matches
the recommended pressure on the Tire
and Loading Information label, no further
adjustment is necessary. If the inflation
pressure is low, add air until the
recommended pressure is reached. If the
inflation pressure is high, press on the
metal stem in the center of the tire valve to
release air.
Recheck the tire pressure with the
tire gauge.
Put the valve caps back on the valve stems
to keep out dirt and moisture.Use only
valve caps designed for the vehicle by
GM.TPMS sensors could be damaged
and would not be covered by the
vehicle warranty.
Tire Pressure Monitor System
T
he Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire
pressure levels. The TPMS sensors monitor
the air pressure in your tires and transmit
tire pressure readings to areceiver located in
the vehicle.
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 indicated 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 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
