cooling JEEP GRAND CHEROKEE 2016 WK2 / 4.G User Guide

STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function was developed to reduce fuel consumption. The system will
stop the engine automatically during a vehicle stop if the required conditions are
met. Releasing the brake pedal or pressing the accelerator pedal will automatically
re-start the engine.
Automatic Mode
The Stop/Start feature is enabled after every normal customer
engine start. At that time, the system will go into STOP/START
READY and if all other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following Must Occur:
• The system must be in STOP/START READY state. A STOP/START READY message will be displayed in the Driver Information Display (DID) within the
Stop/Start section. Refer to “Driver Information Display (DID)” in “Understanding
Your Instrument Panel” in your owner’s manual on the DVD for further information.
• The vehicle must be completely stopped.
• The shifter must be in a forward gear and the brake pedal depressed.
The engine will shut down, the tachometer will move to the zero position and the
Stop/Start telltale will illuminate indicating you are in Autostop. Customer settings
will be maintained upon return to an engine running condition.
Refer to the “Stop/Start System” in the “Starting And Operating” section located in
your Owner’s Manual on the DVD for further information.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many safety and comfort conditions
to see if they are fulfilled. Detailed information about the operation of the Stop/Start
system may be viewed in the DID Stop/Start Screen. In the following situations, the
engine will not stop:
• Driver’s seat belt is not buckled.
• Driver’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.
• Cabin heating or cooling is in process and an acceptable cabin temperature has not been achieved.
• HVAC is set to full defrost mode at a high blower speed.

ROADSIDE ASSISTANCE
Dial toll-free 1-800-521-2779 for U.S. Residents or 1-800-363-4869 for Canadian
Residents.
• Provide your name, vehicle identification number, license plate number, and yourlocation, including the telephone number from which you are calling.
• Briefly describe the nature of the problem and answer a few simple questions.
• You will be given the name of the service provider and an estimated time of arrival. If you feel you are in an “unsafe situation”, please let us know. With your consent,
we will contact local police or safety authorities.
INSTRUMENT CLUSTER WARNING LIGHTS
– Battery Charge Warning Light
This light illuminates when the battery is not charging properly. If the battery charge
warning light remains on, it means that the vehicle is experiencing a problem with the
charging system.
We recommend you do not continue driving if it is on. Have the vehicle serviced
immediately.
– Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
– 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.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant.
WHAT TO DO IN EMERGENCIES
189

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.

Preparations For Jump-Start
The battery in your vehicle is located under the passenger's front seat. There are
remote locations located under the hood to assist in jump-starting.
WARNING!
• Take care to avoid the radiator cooling fan whenever the hood is raised. It canstart anytime the ignition switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch bands and bracelets that could
make an inadvertent electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate
hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
NOTE:
Be sure that the disconnected ends of the cables do not touch while still connected
to the either vehicle.
1. Set the parking brake, shift the automatic transmission into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
3. Remove the protective cover over the remote positive (+)battery post. Pull upward
on the cover to remove it.
4. If using another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the ignition is OFF.

CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic AdditiveTechnology (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.90032), 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.
