Call any Jeep dealerm, they should tell you.
If you've no dealer, and no one knows in any garage, ask another Jeep owner to look at his owner's manual in the glove box to get that number.
Look under the heading of "Capacities".
God bless your efforts.

If it thinks it really is in 4x4 your top speed is limited to what the system will handle.
Check your owners manual for details.

you dont know how to check fuses?
is that the question
why 1: look at em' if they look blown they are, some that look ok are i fact not ok.
way2: use a voltmeter, key on, both sides 12v, if not, its bad. if one side is 12v and other side not. this is 100% accurate test.

2008 jeep cherokee (hemi) engine light its on i brought to fix they change 4 sensor and the converter. After 5 days engine light comes on again, what else can be? im depress about it, after paying almost 2 grand to fix this issue.

Possible causes
- Low oil level or motor mechanical fault
- Faulty oil pressure sensor
- Oil Pressure Sensor harness is open or shorted
- Oil Pressure Sensor circuit poor electrical connection

When is the code detected?
The P0521 is detected when the signal sent from oil pressure sensor to PCM goes out of range.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Oil pressure warning light ON.
P0521 Chevrolet Description
The PCM continuously monitors the engine oil pressure. The Oil Pressure Sensor/Switch sends a signal to the PCM when the engine is running.
