Tire Pressure Monitor

(if equipped)

The Tire Pressure Monitor alerts you when a

significant reduction in pressure occurs in

one or more of your vehicle’s tires by

illuminating the (low tire pressure)

warning light on the instrument panel cluster.

The low tire pressure warning light will

remain on until you correct the tire pressure.

A CHECK TIRE PRESSURE message may

also appear on the DIC (if equipped).

Correcting the Tire Pressure

When the low tire pressure warning light

illuminates, you must fill the tire to the proper

tire inflation pressure (just as you must refuel

the vehicle when the low fuel warning light

illuminates). The Tire and Loading

Information label shows the correct inflation

pressure for the tires when they’re cold.

“Cold” means your vehicle has been sitting

for at least three hours or driven no more

than one mile.

You can temporarily clear the DIC message

by acknowledging it with your DIC controls.

However, at the next vehicle startup, the DIC

message will reappear if the tire pressure

has not been corrected.

During cooler conditions, the low tire

pressure warning light may appear when the

vehicle is first started and then turn off as

you start to drive the vehicle. This could be

an early indicator that your tire pressures are

getting low and need to be inflated to the

proper pressure.

See Section 5 of your Owner Manual.

Note: The Tire Pressure Monitor can alert

you about low tire pressure, but it doesn’t

replace normal monthly tire maintenance.

Resetting the Engine Oil Life

System

The Oil Life System calculates engine oil life

based on vehicle use and displays CHANGE

ENGINE OIL SOON in the Driver Information

Center (DIC) when it’s necessary to change

your engine oil and filter. The Oil Life System

should be reset to 100% only following an oil

change.

To reset the Oil Life System:

1. Turn the key to On, with the engine off.

2. Press the (Vehicle Information)

button until the DIC displays ENGINE OIL

3. Press and hold the (Set/Reset)

button until 100% ENGINE OIL LIFE is

displayed.

4. Turn the key to Off.

See Section 5 of your Owner Manual.
