2015 JEEP CHEROKEE stop start

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

With Tip Start
If the engine fails to start after you have followed the
#Normal Starting#, “Extreme Cold Weather#and#Ex-
tended Park Starting#procedures, it may be flooded. To
clear any excess fuel, press the accelerator pedal all the
way to the floor and hold it. Then, cycle the ignition
switch to the START position and release it as soon as the
starter engages. The starter motor will disengage auto-
matically in 10 seconds. Once this occurs, release the
accelerator pedal, cycle the ignition to the LOCK posi-
tion, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15
seconds before trying again.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
STOP/START SYSTEM — 3.2L ENGINE
The Stop/Start function is developed to reduce emis-
sions. 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.
5
STARTING AND OPERATING 475

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.

Information Center (EVIC)” or “Driver Information Dis-
play (DID)“ in “Understanding Your Instrument Panel”
for further information.
If the “SERVICE STOP/START SYSTEM” message ap-
pears in the EVIC, have the system checked by your
authorized dealer.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine and permits
quicker starts in cold weather.
Connect the cord to a 110-115 Volt AC electrical outlet
with a grounded, three-wire extension cord.
For ambient temperatures below 0°F (-18°C), the engine
block heater is recommended. For ambient temperatures
below -20°F (-29°C), the engine block heater is required.
The engine block heater cord is routed under the hood,
behind to the driver ’s side headlamp. Follow the steps
below to properly use the engine block heater:
1. Locate the engine block heater cord (behind the driv-
er ’s side headlamp).
2. Undo the Velcro strap that secures the heater cord in
place.
3. Pull the cord to the front of the vehicle and plug it into
a grounded, three-wire extension cord.
4. After the vehicle is running, reattach the cord to the
Velcro strap and properly stow away behind the
driver ’s side headlamp.
480 STARTING AND OPERATING

CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
•Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
•Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE:You must press and hold the brake pedal while
shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/
OFF (key removal) position. The key fob can only be
removed from the ignition when the ignition is in the
LOCK/OFF position, and the transmission is locked in
PARK whenever the ignition switch is in the LOCK/OFF
position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the ignition switch must be turned to the
ON/RUN position (engine running or not) and the brake
pedal must be pressed.
The brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.
