Jeep 2005 Grand Cherokee - Manual (Page 182)

Tire Pressure Display — If Equipped
Shows the current pressure of all 4 road tires.
NOTE: Tires heat up during normal driving conditions.
Heat will cause the tire pressure to increase from 2 to 6
psi (14 to 41 kPa) during normal driving conditions. Refer
to “Tire Inflation Pressures” in Section 5 for additional
information.
Miles to Service
Shows the distance remaining to require service.
NOTE: This display can be reset to the set service
interval by pressing and holding the RESET button for 3
seconds.
Blank Screen
Shows a blank screen. Pressing the C/T button returns to
the compass/temperature display.
Automatic Compass Calibration
This compass is self-calibrating which eliminates the
need to manually set the compass. When the vehicle is
new, the compass may appear erratic and the CAL
symbol will be displayed.
After completing one 360 degree turn, with the vehicle
traveling less than 5 mph (8 km/h), in an area free from
large metal or metallic objects, the CAL symbol will turn
off and the compass will function normally.
