23_JL_OM_EN_USC_t.book Page 118

132STARTING AND OPERATING
STOPPING THE ENGINE
After full load operation, idle the engine for a few minutes before shutting it down. This idle period will allow the lubricating oil and coolant to carry excess heat away from the
turbocharger.
NOTE:Refer to the following chart for proper engine shutdown.
NOTE:Under certain conditions the engine fan will run after the
engine is turned off. These conditions are under high load
and high temperature conditions.
COOLING SYSTEM TIPS — AUTOMATIC
T
RANSMISSION
To reduce the potential for engine and transmission
overheating in high ambient temperature conditions, take
the following actions:
 City Driving — When stopped, shift the transmission
into NEUTRAL (N) and increase engine idle speed.
 Highway Driving — Reduce your speed. 
Up Steep Hills — Select a lower transmission gear.
 Air Conditioning — Turn it off temporarily.
NOTE:If the coolant temperature is too high, the A/C will auto -
matically turn off.
Do Not Operate The Engine With Low Oil
Pressure
If the Oil Pressure Warning Light turns on while driving,
stop the vehicle and shut down the engine as soon as
possible. A chime will sound when the light turns on. After
the vehicle is safely stopped, restart the engine and
monitor the Oil Pressure Warning Light. If the Oil Pressure
Warning Light is still illuminated, turn the engine OFF and contact an authorized dealer for further assistance. If the
lamp is no longer illuminated, the engine can be operated
but it is recommended to take the vehicle to an authorized
dealer as soon as possible.
NOTE:Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine. The
engine oil level must be checked under the hood.

23_JL_OM_EN_USC_t.book Page 132

STARTING AND OPERATING133
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the parts fail.
Be on the alert for changes in performance, sounds, and
visual evidence that the engine requires service. Some
important clues are:
Engine misfiring or vibrating severely
 Sudden loss of power
 Unusual engine noises
 Fuel, oil or coolant leaks
 Sudden change, outside the normal operating range, in
the engine operating temperature
 Excessive smoke
 Oil pressure drop
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE (IF EQUIPPED)
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
Úpage 374.
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 inter
-
preted as a problem.
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE (IF EQUIPPED)
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, providing
the following recommendations are followed:
 Warm up the engine before placing it under load.
 Do not operate the engine at idle for prolonged periods.
 Use the appropriate transmission gear to prevent
engine lugging.
 Observe vehicle oil pressure and temperature indica -
tors.
 Check the coolant and oil levels frequently.
 Vary throttle position at highway speeds when carrying
or towing significant weight.
NOTE:Light duty operation such as light trailer towing or no load
operation will extend the time before the engine is at full
efficiency. Reduced fuel economy and power may be seen
at this time.
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
recommended viscosity and quality grades see
Úpage 374. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
PARKING BRAKE
Before exiting the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave an
automatic transmission in PARK, or manual transmission
in REVERSE or FIRST gear.
The parking brake lever is located in the center console.
To apply the parking brake, pull the lever up as firmly as
possible. To release the parking brake, pull the lever up
slightly, push the center button, then lower the lever
completely.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.

182STARTING AND OPERATING
DRIVING ACROSS AN INCLINE
If at all possible, avoid driving across an incline. If it is
necessary, know your vehicle's abilities. Driving across an
incline places more weight on the downhill wheels, which
increases the possibilities of a downhill slide or rollover.
Make sure the surface has good traction with firm and
stable soils. If possible, transverse the incline at an angle
heading slightly up or down.
IF YOU STALL OR BEGIN TO LOSE HEADWAY
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift into
REVERSE. Back slowly down the hill allowing engine
braking to control the descent and apply your brakes, if
necessary, but do not allow the tires to lock.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided, if possible, and only
be attempted when necessary in a safe, responsible
manner. Only drive through areas which are designated
and approved. Tread lightly and avoid damage to the
environment. Know your vehicle's abilities and be able to
recover it if something goes wrong. Never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. Shift into
FIRST gear (manual transmission), or DRIVE (automatic
transmission), with the transfer case in the 4L position
and proceed very slowly with a constant slow speed of {3
to 5 mph (5 to 8 km/h) maximum} and light throttle. Keep
the vehicle moving; do not try to accelerate through the
crossing. After crossing any water higher than the bottom
of the axle differentials, inspect all of the vehicle fluids for
signs of water ingestion.
BEFORE YOU CROSS ANY TYPE OF WATER
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick. You
need to be sure of its depth, approach angle, current and
bottom condition. Be careful of murky or muddy waters;
check for hidden obstacles. Make sure you will not be
intruding on any wildlife, and you can recover the vehicle
if necessary. The key to a safe crossing is the water depth,
current and bottom conditions. On soft bottoms, the
vehicle will sink in, effectively increasing the water level on
the vehicle. Be sure to consider this when determining the
depth and the ability to safely cross.
CROSSING PUDDLES, POOLS, FLOODED
AREAS OR OTHER STANDING WATER
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to entering.
This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.
WARNING!
Driving across an incline increases the risk of a rollover,
which may result in severe injury.
WARNING!
If the engine stalls or you lose headway or cannot make
it to the top of a steep hill or grade, never attempt to
turn around. To do so may result in tipping and rolling
the vehicle, which may result in severe injury. Always
back carefully straight down a hill in REVERSE. Never
back down a hill in NEUTRAL using only the vehicle
brakes. Never drive diagonally across a hill, always drive
straight up or down.
CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can
cause permanent damage to engine, driveline or
other vehicle components, and your brakes will be
less effective once wet and/or muddy.
 When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering
as a precaution, and check all fluids afterward.
Driving through water may cause damage that may
not be covered by the New Vehicle Limited Warranty.
CAUTION!
Muddy waters can reduce the cooling system
effectiveness by depositing debris onto the radiator.
