Checking tire pressures manually
To determine and set the correct tire pressure,
proceed as follows:
Remove the valve cap of the tire that is to be
X
checked.
Press the tire pressure gage securely onto the
X
valve.
Read the tire pressure and compare it to the
X
recommended value on the Tire and Loading
Information placard or the tire pressure table
( page 324).
Y
If the tire pressure is too low, increase the tire
X
pressure to the recommended value.
If the tire pressure is too high, release air. To
X
do so, press down the metal pin in the valve,
using the tip of a pen for example. Then check
the tire pressure again using the tire pressure
checker.
Screw the valve cap onto the valve.

Repeat these steps for the other tires.

Tire pressure monitor
General notes
If a tire pressure monitor is installed, the vehi-
cle's wheels have sensors that monitor the tire
pressures in all four tires. The tire pressure mon-
itor warns you if the pressure drops in one or
more of the tires. The tire pressure monitor only
functions if the corresponding sensors are
installed in all wheels.
Information on tire pressures is displayed in the
multifunction display. After a few minutes of
driving, the current tire pressure of each tire is
shown in the Service menu of the multifunction
display; see illustration (example).
