CHECK TIRE PRESSURE or TIRE LOW
ADD AIR TO TIRE
If your vehicle has the Tire Pressure Monitor
System (TPMS), this message displays when the
pressure in one or more of the vehicle’s tires is low.
The low tire pressure warning light will also come on.
See Tire Pressure Light on page 4-30. This message will
also indicate which tire needs to be checked. You can
receive more than one tire pressure message at a time.
To read the other messages that may have been sent
at the same time, press the set/reset button. If a tire
pressure message appears on the DIC, stop as soon as
you can. Have the tire pressures checked and set to
those shown on the Tire Loading Information label.
See Tires on page 6-60, Loading the Vehicle on
page 5-19, and Inflation - Tire Pressure on page 6-68.
The DIC also shows the tire pressure values. See DIC
Operation and Displays on page 4-37.
DRIVER DOOR OPEN
This message displays and a chime sounds if the driver
door is not fully closed and the vehicle is in a drive
gear. Stop and turn off the vehicle, check the door for
obstructions, and close the door again. Check to
see if the message still appears on the DIC.
ENGINE HOT A/C
(Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
See Engine Coolant Temperature Gage on page 4-29.
To avoid added strain on a hot engine, the air
conditioning compressor automatically turns off. When
the coolant temperature returns to normal, the air
conditioning compressor turns back on. You can
continue to drive your vehicle.
If this message continues to appear, have the system
repaired by your dealer/retailer as soon as possible
to avoid damage to the engine.
