Action when warned of low tire
pressure
When the system for monitoring inflation pres-
sure
13
detects low inflation pressure in a tire,
immediate action is required.
If the system's indicator symbol illumi-
nates and the message
Tire pressure
low is displayed, check the tire pres-
sure and inflate if necessary.
1. Switch off the ignition.
2. Check the inflation pressure on all four tires
using a tire pressure gauge.
3. Inflate the tire to the correct inflation pres-
sure; see the tire pressure placard on the
driver's side B pillar for recommended pres-
sures for factory-mounted tires.
4. Through calibration of the system via the
center display after the tire pressure has
been adjusted.
Please be aware that the indicator symbol
will not go out until the low tire pressure has
been corrected and the system has been
recalibrated.
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 tempera-
ture 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.
