ENGINE BREAK-IN RECOMMENDATIONS
• A long break-in period is not required for the engine and drivetrain
(transmission and axle) in your vehicle.
• Drive moderately during the first 300 miles (500 km). After the initial
60 miles (100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
• While cruising, brief full-throttle acceleration within the limits of local
traffic laws contributes to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental and should be avoided.
• The engine oil installed in the engine at the factory is a high-quality
energy conserving type lubricant. Oil changes should be consistent with
anticipated climate conditions under which vehicle operations will occur.
For the recommended viscosity and quality grades, refer to “Maintaining
Your Vehicle”.
NOTE:A new engine may consume some oil during its first few thousand
miles (kilometers) of operation. This should be considered a normal part of
the break-in and not interpreted as an indication of difficulty.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or
damage may result.
OPERATING YOUR VEHICLE
21

COMMAND-TRAC®/ROCK-TRAC®
• The transfer case provides four
mode positions: 2H (Two-wheel
drive high range), 4H (Four-wheel
drive high range), N (Neutral), and
4L (Four-wheel drive low range).
• The transfer case is intended to be
driven in the 2H position for
normal street and highway
conditions such as hard-surfaced
roads.
• Shifting between 2H and 4H can
be made with the vehicle stopped
or in motion. Shift the transfer
case lever firmly to 4H at any
speed up to 50 mph (80 km/h).
• Shifting between 4H and 4L can be made with the vehicle rolling at 2 to
3 mph (3 to 5 km/h). Shift the automatic transmission into NEUTRAL or
fully depress the clutch pedal on a manual transmission. Shift the transfer
case lever firmly to 4L (do not pause with the transfer case in
NEUTRAL). Once the shift is completed, place the automatic
transmission into DRIVE or release the clutch pedal on a manual
transmission.
NOTE:To enhance off-road performance in 4L mode, manual transmission
vehicles will start regardless of whether or not the clutch pedal is depressed.
AXLE LOCK (TRU-LOK®) RUBICON ONLY
• The AXLE LOCK switch is located on the instrument panel (to the left of
the steering column).
• This feature will only activate when the following conditions are met:
• Key in ignition, vehicle in 4L (Low) range.
• Vehicle speed at 10 mph (16 km/h) or less.
• Press the bottom of the AXLE LOCK switch once to lock the rear axle
only and a second time to lock the front axle (the rear and front axle lock
indicator lights will illuminate).
• To unlock the axles, press the top of the AXLE LOCK switch.
• The indicator light will flash until the axles are fully locked or unlocked.

Shifting Out of NEUTRAL (N)
Use the following procedure to prepare your vehicle for normal usage.
1. Bring the vehicle to a complete stop, leaving it connected to the tow
vehicle.
2. Firmly apply the parking brake.
3. Turn the ignition switch to the ON/RUN position, but do not start the
engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Shift the transfer case lever to the desired position.

transmission in Neutral.
8. Release the brake pedal.
9. Disconnect vehicle from the tow vehicle.
10. Start the engine.
11. Press and hold the brake pedal.
12. Release the parking brake.
13. Shift the transmission into gear, release the brake pedal (and clutch
pedal on manual transmissions), and check that the vehicle operates
normally.
CAUTION!
• It is necessary to follow these steps to be certain that the transfer
case is fully in NEUTRAL (N) before recreational towing to prevent
damage to internal parts.
• Damage to the transmission may occur if the transmission is shifted
into PARK with the transfer case in NEUTRAL (N) and the engine
running. With the transfer case in NEUTRAL (N) ensure that the
engine is OFF prior to shifting the transmission into PARK.
• Front or rear wheel lifts should not be used. Internal damage to the
transmission or transfer case will occur if a front or rear wheel lift is
used when recreational towing.
• Tow only in the forward direction. Towing this vehicle backwards
can cause severe damage to the transfer case.
• Automatic transmissions must be placed in the PARK position for
recreational towing.
