engine JEEP GRAND CHEROKEE 2016 WK2 / 4.G Workshop Manual

– 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 when the vehicle has completely stopped and the 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.
– Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly, when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a Tire Pressure
Monitoring System (TPMS) which display in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID) when one or more of your tires is
significantly under-inflated. Accordingly, when the low tire pressure EVIC or DID
display illuminates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping
ability.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
After inflation, the vehicle may need to be driven for 20 minutes before the flashing light
will turn off.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the TPMS low EVIC or DID display.

– Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called
OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several of your typical
driving cycles. In most situations, the vehicle will drive normally and will not require
towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause
damage to the engine control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic converter damage and power
loss will soon occur. Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher
temperatures than in normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious injury to the driver, occupants
or others.
– Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
The “ESC Activation/Malfunction Indicator Light” in the instrument cluster will
come on when the ignition switch is turned to the ON/RUN position. It should go out
with the engine running. If the “ESC Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see your
authorized dealer as soon as possible to have the problem diagnosed and corrected.
NOTE:
• The “ESC Off Indicator Light” and the “ESC Activation/Malfunction IndicatorLight” come on momentarily each time the ignition switch is turned to ON/RUN.
• Each time the ignition is turned to ON/RUN, the ESC system will be ON, even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when ESC becomes inactive following the maneuver
that caused the ESC activation.

Engine Oil Life Reset
Oil Change Required
Your vehicle is equipped with an engine oil change indicator system. The “Oil Change
Required” message will display in the DID for five seconds after a single chime has
sounded, to indicate the next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the engine oil change interval may
fluctuate, dependent upon your personal driving style.
Unless reset, this message will continue to display each time you turn the ignition
switch to the ON/RUN position or cycle the ignition to the ON/RUN position if
equipped with Keyless Enter-N-Go. To turn off the message temporarily, push and
release the OK button. To reset the oil change indicator system (after performing the
scheduled maintenance) refer to the following procedure.
Vehicles Equipped With Keyless Enter-N-Go
1. Without pushing the brake pedal, push the ENGINE START/STOP button andplace 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 pushing the brake pedal, push the ENGINE START/STOP button once to return the ignition to the OFF/LOCK position.
NOTE:
If the indicator message illuminates when you start the vehicle, the oil change
indicator system did not reset. If necessary, repeat this procedure.
NOTE:
It can also be reset using the Oil Life menu in Vehicle Info.

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the potential for overheating by
taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do notincrease the engine idle speed while preventing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat from the engine cooling
system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.

JACKING AND TIRE CHANGING
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to movingtraffic. Pull far enough off the road to avoid the danger of being hit when
operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the
jack and fall on you. You could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get under a raised vehicle, take
it to a service center where it can be raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack
should not be used to lift the vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or slippery areas.
Run Flat Tires — SRT Models
This vehicle is equipped with “run flat” tires. Run flat tires allow the vehicle to be
driven approximately 50 miles (80km) at 55 mph (88km/h). Tire service should be
obtained to avoid prolonged run flat feature usage.
WARNING!
Do not exceed 50 mph (80 km/h) if the “Tire Pressure Monitoring Telltale Light”
is illuminated. Vehicle handling and braking may be reduced. You could have a
collision and be severely or fatally injured.

Jacking Instructions
WARNING!
Carefully follow these tire changing warnings to help prevent personal injury or
damage to your vehicle:
• Always park on a firm, level surface as far from the edge of the roadway aspossible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Chock the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in PARK.
• Never start or run the engine with the vehicle on a jack.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack. If you need to get under a
raised vehicle, take it to a service center where it can be raised on a lift.
• Only use the jack in the positions indicated and for lifting this vehicle during
a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely stowed, spares must be
stowed with the valve stem facing the ground.

WARNING!
Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in damage to the charging system
of the booster vehicle or the discharged vehicle.
NOTE:
Make sure at all times that unused ends of jumper cables are not contacting each
other or either vehicle while making connections.
Connecting The Jumper Cables
1. Connect the positive (+)end of the jumper cable to the remote positive (+)post
of the discharged vehicle.
2. Connect the opposite end of the positive (+)jumper cable to the positive (+)post
of the booster battery.
3. Connect the negative end (-)of the jumper cable to the negative (-)post of the
booster battery.
4. Connect the opposite end of the negative (-)jumper cable to the remote negative
(-) post of the vehicle with the discharged battery.
WARNING!
Do not connect the jumper cable to the negative (-)post of the discharged battery.
The resulting electrical spark could cause the battery to explode and could result
in personal injury. Only use the specific ground point, do not use any other exposed
metal parts.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start the engine in the vehicle with the discharged battery.
WHAT TO DO IN EMERGENCIES
208

CAUTION!
Do not run the booster vehicle engine above 2000 rpm since it provides no
charging benefit, wastes fuel and can damage booster vehicle engine.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable from the remote negative (-)
post of the discharged vehicle.
2. Disconnect the opposite end of the negative (-)jumper cable from the negative (-)
post of the booster battery.
3. Disconnect the positive (+)end of the jumper cable from the positive (+)post of
the booster battery.
4. Disconnect the opposite end of the positive (+)jumper cable from the remote
positive (+)post of the discharged vehicle.
5. Reinstall the protective cover over the remote positive (+)post of the discharged
vehicle.
If frequent jump-starting is required to start your vehicle you should have the battery
and charging system tested at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets draw power from the vehicle’s
battery, even when not in use (i.e., cellular devices, etc.). Eventually, if plugged in
long enough without engine operation, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the engine from starting.
EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, there will be one in the rear and two
mounted on the front of the vehicle. The rear hook will be located on the driver's side
of the vehicle.
NOTE:
For off-road recovery, it is recommended to use both of the front tow hooks to
minimize the risk of damage to the vehicle.
WARNING!
• Do not use a chain for freeing a stuck vehicle. Chains may break, causing serious injury or death.
• Stand clear of vehicles when pulling with tow hooks. Tow straps may become
disengaged, causing serious injury.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial
towing service. If the transmission and drivetrain are operable, disabled vehicles may
also be towed as described under “Recreational Towing” in the “Starting and
Operating” section in the Owners Manual on the DVD.
NOTE:
Vehicles equipped with Quadra-Lift must be placed in Transport mode, before tying
them down (from the body) on a trailer or flatbed truck. Refer to the section on
Quadra-Lift for more information. If the vehicle cannot be placed in Transport mode
(for example, engine will not run), tie-downs must be fastened to the axles (not to the
body). Failure to follow these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.

If you must use the accessories (wipers, defrosters, etc.) while being towed, the
ignition must be in the ON/RUN position, not the ACC position.
If the key fob is unavailable, or the vehicle's battery is discharged, refer to “Manual
Park Release” in this section for instructions on shifting the transmission out of
PARK for towing.
CAUTION!
• Do not use sling type equipment when towing. Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not attach to front or rearsuspension components. Damage to your vehicle may result from improper
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with all four wheels OFFthe
ground using a flatbed.
If flatbed equipment is not available, and the transmission is operable, the vehicle
may be towed (with rear wheels on the ground) under the following conditions:
• The transmission must be in NEUTRAL. Refer to "Manual Park Release" in this section for instructions on shifting the transmission to NEUTRAL when the engine
is off.
• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 30 miles (48 km).
If the transmission is not operable, or the vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km), tow with the rear wheels OFFthe ground.
Acceptable methods are to tow the vehicle on a flatbed, or with the front wheels
raised and the rear wheels on a towing dolly, or (when using a suitable steering wheel
stabilizer to hold the front wheels in the straight position) with the rear wheels raised
and the front wheels on the ground.
CAUTION!
Towing faster than 30 mph (48 km/h) or farther than 30 miles (48 km) with rear
wheels on the ground can cause severe transmission damage. Damage from
improper towing is not covered under the New Vehicle Limited Warranty.
