2015 JEEP GRAND CHEROKEE ECU

REMOTE STARTING SYSTEM
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
•The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
•Obstructions between the vehicle and the RKE trans-
mitter may reduce this range.•The Remote Start system will wait for the “Wait To
Start” amber telltale to extinguish before cranking the
engine. This allows time for the engine pre-heat cycle
to pre-heat the cylinder air, and is normal in cold
weather. Refer to “Electronic Vehicle Information Dis-
play (EVIC)” in “Understanding Your Instrument
Panel” for further information on the “Wait To Start”
amber telltale and the pre-heat cycle.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•HAZARD switch off
•BRAKE switch inactive (brake pedal not pressed)
8 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Battery at an acceptable charge level
•RKE PANIC button not pressed
•Fuel meets minimum requirement
•System not disabled from previous remote start event
•Vehicle security alarm not active
•Water In Fuel Indicator Light is not illuminated
•“Wait To Start” telltale is not illuminatedWARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Mon-
oxide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious in-
jury or death when inhaled.
•Keep Remote Keyless Entry (RKE) transmitters
away from children. Operation of the Remote Start
System, windows, door locks or other controls
could cause serious injury or death.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 9

17. Selectable DID Menu
This area of the cluster will display the DID selectable
menu. For further information, refer to “Driver Informa-
tion Display (DID)” in this section.
18. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to the ON/RUN position. If the light is
either not on during starting, stays on, or turns
on while driving, have the system inspected at an autho-
rized dealer as soon as possible. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” of your owners manual for further information.
19. Vehicle Security Light
This light will flash rapidly for approximately
15 seconds when the vehicle theft alarm is
arming. The light will flash at a slower speedcontinuously after the alarm is set. The security light will
also come on for about three seconds when the ignition is
first turned on.
20. Electronic Stability Control (ESC) OFF Indicator
Light — If Equipped
This light indicates the Electronic Stability Con-
trol (ESC) is off.
21. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped
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 In-
dicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC

UNDERSTANDING YOUR INSTRUMENT PANEL 21

CAUTION!(Continued)
•Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
Perform the maintenance listed in the “Maintenance
Schedule.” Refer to “Maintenance Schedule” for the
proper maintenance intervals. When towing a trailer,
never exceed the GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
(Continued)
WARNING!(Continued)
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.

58 STARTING AND OPERATING

WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
(Continued)
WARNING!(Continued)
This could result in a accident.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
•Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in an accident.
