oil change JEEP GRAND CHEROKEE 2014 WK2 / 4.G User Guide

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 an engine problem or malfunction.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may
result.
SRT Engine Break-In Recommendations
SRT Engine Break-In Recommendations: The following tips will be helpful in
obtaining optimum performance and maximum durability for your new SRT Vehicle.
Despite modern technology and World Class manufacturing methods, the moving
parts of the vehicle must still wear in with each other. This wearing in occurs mainly
during the first 500 miles (805 km) and continues through the first oil change
interval.
It is recommended for the operator to observe the following driving behaviors during
the new vehicle break-in period:
0 to 100 miles (0 to 161 km):
• Do not allow the engine to operate at idle for an extended period of time.
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid
acceleration.
• Avoid aggressive braking.
• Drive with the engine speed less than 3,500 RPM.
• Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.
OPERATING YOUR VEHICLE
28

100 to 300 miles (161 to 483 km):
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid
acceleration in lower gears (1st to 3rd gears).
• Avoid aggressive braking.
• Drive with the engine speed less than 5,000 RPM.
• Maintain vehicle speed below 70 mph (112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shifting manually (paddles or gear shift) at
higher rpms when possible.
• Do not perform sustained operation with the accelerator pedal at wide open
throttle.
• Maintain vehicle speed below 85 mph (136 km/h) and observe local speed limits.
For the first 1500 mi (2414 km):
• Do not participate in track events, sport driving schools, or similar activities during
the first 1500 mi (2414 km).
NOTE:
Check engine oil with every refueling and add if necessary. Oil and fuel consumption
may be higher through the first oil change interval.
HEADLIGHT SWITCH
Automatic Headlights/Parking
Lights/Headlights
• Rotate the headlight switch, located
on the instrument panel to the left of
the steering wheel, to the first detent
for parking lights
and to the
second detent for headlights
.
• With the parking lights or low beam
headlights on, push the headlight
switch once for fog lights.
• Rotate the headlight switch to “A” for
AUTO headlights.
When set to “A” (AUTO), the system
automatically turns the headlights on or
off based on ambient light levels.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
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 indicators.
• 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. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
DIESEL ENGINE STARTING PROCEDURES
Normal Starting Procedure
1. Apply the parking brake.
2. Ensure the shift lever is in the PARK position.
3. Press and hold the brake pedal while pressing the ENGINE START/STOP button
once.
4. The system will take over and attempt to start the vehicle. If the vehicle fails to
start, the starter will disengage automatically after 30 seconds.
5. If you wish to stop the cranking of the engine prior to the engine starting, press the
button again.
6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.

- Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition key when the vehicle has completely stopped and the shift lever/gear selector
is placed in the PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when the
engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require towing.
- Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb check when the ignition
switch is first turned to the ON/RUN position. If the light is either not on during
starting, stays on, or turns on while driving, have the system inspected at an
authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things To
Know Before Starting Your Vehicle” of your Owner’s Manual for further information.
NOTE:
The Air Bag System is designed to be maintenance free.
Oil Change Indicator
Message
If an “oil change” message (shown as Oil Change Due) appears and a single chime
sounds, it is time for your next required oil change:
1. Without pressing the brake pedal, push the ENGINE START/STOP button and
cycle the ignition to the ON/RUN position (do not start the engine.)
2. Fully depress the accelerator pedal, slowly, three times within 10 seconds.
3. Without pressing the brake pedal, push the ENGINE START/STOP button once to
return the ignition to the OFF/LOCK position.
- Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.
WHAT TO DO IN EMERGENCIES
155

CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic Additive
Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS-12106), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products.
Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine
coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
MAINTENANCE SCHEDULE — GASOLINE ENGINE
Your vehicle is equipped with an automatic oil change indicator system. The oil
change indicator system will remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures,
