Volvo XC90: Wheels and tires / Action when warned of low tire pressure
When the tire inflation pressure monitoring system1 detects low
inflation pressure in a tire, immediate action is required.
If the system's indicator symbol
illuminates and the message Tire pressure low is displayed, check the tire
pressure and inflate if necessary.
- Switch off the ignition.
- Check the inflation pressure on all four tires using a tire pressure gauge.
- Inflate the tire to the correct inflation pressure; see the tire pressure
placard on the driver's side B pillar for recommended pressures for factory-mounted
tires.
- After the inflation pressure has been adjusted, always save the new inflation
pressure in the system via the center display. Please be aware that the indicator
symbol will not go out until the low tire pressure has been corrected and a
storing procedure has been started for the new inflation pressure.
NOTE
To help prevent incorrect inflation pressure, pressure should be checked
when the tires are cold. The tires are considered to be cold when they have reached
the same temperature as the ambient temperature (about 3 hours after the vehicle
was last driven). After driving for a few kilometers, the tires will warm up and
the pressure will increase.
NOTE
- After inflating a tire, always replace the valve cap to help prevent
valve damage caused by gravel, dirt, etc.
- Use plastic valve caps only. Metal caps could corrode and become difficult
to remove.
WARNING
- Incorrect inflation pressure could lead to tire failure, which could
cause the driver to lose control of the vehicle.
- The system cannot predict sudden tire damage.
1 Tire Pressure Monitoring System (TPMS)
With the system for tire inflation pressure monitoring1, inflation
pressure status can be viewed in the center display.
Checking status
The vehicle may need to be driven for a few minutes at a speed above 35 km/h
(22 mph) to activate the system...
(Option/accessory.)
A number of messages related to the tire inflation pressure monitoring system1
may be displayed. Several examples are provided below...
Other information:
(Option/accessory.)
The function for assisting when driving downhill (HDC1) is a low-speed
function with increased engine braking. The function makes it possible to increase
or decrease the vehicle's speed on steep downhill gradients by only using the accelerator
pedal, without applying the brakes...
In order for the tire inflation pressure monitoring system1 to
function correctly, inflation pressure reference values must be saved correctly.
To help ensure that the system can correctly alert the driver of low inflation pressure,
this must be done each time the tires are changed or the inflation pressure is adjusted...
