2017 JEEP GRAND CHEROKEE TRAILHAWK engine

The Keyless Push Button Ignition has four operating
modes which are labeled and will illuminate when in
position. The three positions are OFF, ACC, RUN, and
START.
NOTE:If the ignition switch does not change with the
push of a button, the key fob may have a low or dead
battery. In this situation, a back up method can be used to
operate the ignition switch. Put the nose side (side opposite
of the emergency key) of the key fob against the ENGINE
START/STOP button and push to operate the ignition
switch. The push button ignition can be placed in the following
modes:
OFF
•
The engine is stopped.
• Some electrical devices (e.g. Central locking, alarm, etc.)
are still available.
ACC
• Engine is not started.
• Some electrical devices are available.
RUN
• Driving position.
• All the electrical devices are available.
START
• The engine will start.

WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep key fobs away from children. Operation of the
Remote Start System, windows, door locks or other
controls could cause serious injury or death.
How To Use Remote Start
• Push Remote Start button on the key fob twice within
five seconds. Pushing the Remote Start button a third
time shuts the engine off.
• With remote start, the engine will only run for 15
minutes (time out) unless the ignition is placed in the
ON/RUN position.
• The vehicle must be manually started with a push of the
ignition START/STOP button after two consecutive time
outs. All of the following conditions must be met before the
engine will remote start:
•
Gear Selector in PARK
• Doors closed
• Hood closed
• Liftgate closed
• Hazard switch off
• Brake switch inactive (brake pedal not pushed)
• Battery at an acceptable charge level
• PANIC button not pushed
• System not disabled from previous remote start event
• Vehicle alarm system indicator flashing
• Ignition in STOP/OFF position
• Fuel level meets minimum requirement

WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon

• Keep key fobs away from children. Operation of the
Remote Start System, windows, door locks or other
controls could cause serious injury or death.
Remote Start Abort Message
The following messages will display in the instrument
cluster display if the vehicle fails to remote start or exits
remote start prematurely:
• Remote Start Cancelled — Door Open
• Remote Start Cancelled — Hood Open
• Remote Start Cancelled — Fuel Low
• Remote Start Aborted Timer Expired
• Remote Start Aborted Liftgate Open
• Remote Start Disabled — Start Vehicle To Reset The instrument cluster display message stays active until
the ignition is turned to the ON/RUN position.
To Enter Remote Start Mode
Push and release the Remote Start button on the key fob
twice within five seconds. The vehicle doors will lock, the
turn signals will flash twice, and the horn will chirp twice.
Then the engine will start, and the vehicle will remain in
the Remote Start mode for a 15-minute cycle.
NOTE:
•
If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
• The park lamps will turn on and remain on during
Remote Start mode.
• For security, power window operation is disabled when
the vehicle is in the Remote Start mode.
• The engine can be started two consecutive times (two
15-minute cycles) with the key fob. However, the igni-
tion must be placed in the ON/RUN position before you
can repeat the start sequence for a third cycle.3

2. Reach under the hood, move safety latch to the left andlift the hood.
To Close The Hood
1. Hold up the hood with one hand and with the otherhand remove the support rod from its seat and reinsert
it into the locking tab.
2. Lower the hood to approximately 12 inches (30 cm) from the engine compartment and drop it. Make sure that the
hood is completely closed.

3. Temperature Gauge•
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up mountain
grades. It should not be allowed to exceed the upper
limits of the normal operating range.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
your authorized dealer for service as soon as possible.

4. Start the engine.
5. Rotate the steering wheel slightly more than one-halfturn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.

on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. BLD may remain enabled even if TCS
and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC corrects
for oversteering or understeering of the vehicle by apply-
ing the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.
•Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” located
in the instrument cluster will start to flash as soon as the ESC
system becomes active. The “ESC Activation/Malfunction
Indicator Light” also flashes when the TCS is active. If the
“ESC Activation/Malfunction Indicator Light” begins to
flash during acceleration, ease up on the accelerator and
apply as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
