Battery JEEP CHEROKEE 2015 KL / 5.G Owner's Manual

CAUTION!
•Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not in
use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life and/or
prevent the engine from starting.
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the bat-
tery even more quickly. Only use these intermit-
tently and with greater caution.
•After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.
POWER INVERTER — IF EQUIPPED
There is a 115 Volt, 150 Watt inverter outlet located on the
back of the center console to convert DC current to AC
current. This outlet can power cellular phones, electron-
ics and other low power devices requiring power up to

Cycle the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, cycle the ignition switch to the
LOCK/OFF position, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure.
Tip Start Feature
Cycle the ignition switch to START position and release it
as soon as the starter engages. The starter motor will
continue to run, but will automatically disengage itself
when the engine is running. If the engine fails to start, the
starter will disengage automatically in 10 seconds. If this
occurs, cycle the ignition switch to the LOCK position,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.
Extreme Cold Weather (Below –20°F Or−29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
Extended Park Starting
NOTE:Extended Park condition occurs when the vehicle
has not been started or driven for at least 35 days.
1. Install a battery charger or jumper cables to the battery
to ensure a full battery charge during the crank cycle.
2. Cycle the ignition in the START position and release it
when the engine starts.
3. If the engine fails to start within ten seconds, cycle the
ignition to the STOP (OFF/LOCK) position, wait five
seconds to allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow
the starter to cool for at least 10 minutes, then repeat
the procedure.

STARTING AND OPERATING 473

CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
(Continued)
WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
•If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
474 STARTING AND OPERATING

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 Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID) within the Stop/
Start section. Refer to “Electronic Vehicle Information
Center (EVIC)” or “Driver Information Display (DID)”
in “Understanding Your Instrument Panel” 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 illumi-
nate indicating you are in Autostop. Customer settings
will be maintained upon return to an engine running
condition.
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 EVIC/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.
476 STARTING AND OPERATING

•Battery charge is low.
•The vehicle is on a steep grade.
•Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved.
•HVAC is set to full defrost mode at a high blower
speed.
•HVAC set to MAX A/C.
•Engine has not reached normal operating temperature.
•The transmission is not in a forward gear.
•Hood is open.
•Vehicle is in 4LO transfer case mode.
•Brake pedal is not pressed with sufficient pressure.
Other Factors Which Can Inhibit Autostop Include:
•Fuel level.
•Accelerator pedal input.
•Engine temp too high.
•5 MPH threshold not achieved from previous AU-
TOSTOP.
•Steering angle beyond threshold.
•ACC is on and speed is set.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.
To Start The Engine While In Autostop Mode
While in a forward gear, the engine will start when the
brake pedal is released or the throttle pedal is depressed.
The transmission will automatically re-engage upon en-
gine restart.
5
STARTING AND OPERATING 477

Conditions That Will Cause The Engine To Start Auto-
matically While In Autostop Mode:
•The transmission selector is moved out of DRIVE.
•To maintain cabin temperature comfort.
•HVAC is set to full defrost mode.
•HVAC system temperature or fan speed is manually
adjusted.
•Battery voltage drops too low.
•Low brake vacuum (e.g. after several brake pedal
applications).
•STOP/START OFF switch is pressed.
•A STOP/START system error occurs.
•4WD system is put into 4LO mode.
Conditions That Force An Application Of The Electric
Park Brake While In Autostop Mode:
•The drivers door is open and brake pedal released.
•The drivers door is open and the drivers seat belt is
unbuckled.
•The engine hood has been opened.
•A STOP/START system error occurs.
If the Electric Park Brake is applied with the engine off,
the engine may require a manual restart and the electric
park brake may require a manual release (depress brake
pedal and press Electric Park Brake switch). Refer to
“Electronic Vehicle Information Center (EVIC)” or
“Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for further information.
478 STARTING AND OPERATING

•Change the engine oil and oil filter.
•Disconnect and reconnect the battery to reset the
engine controller memory.
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.
