2014 JEEP CHEROKEE stop start

actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.
• Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE: Do not cut or splice wiring into the vehicles
wiring harness.
540 STARTING AND OPERATING

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing the trailer in an area located away from
heavy traffic.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent shift-
ing does occur while in DRIVE, use the Electronic Range
Select (ERS) shift control to select a lower gear range.
NOTE:Using a lower gear range while operating the
vehicle under heavy operating conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat build up. This action will also
provide better engine braking.
Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads. •
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
542 STARTING AND OPERATING

CAUTION!
It is necessary to follow these steps to be certain that
the power transfer unit is fully in NEUTRAL (N)
before recreational towing to prevent damage to
internal parts.
1. Bring the vehicle to a complete stop and shift the transmission to PARK.
2. Turn the engine OFF.
3. Turn the ignition switch to the ON/RUN position, but do not start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object, press and hold the recessed NEUTRAL (N) button (located by the
selector switch) for four seconds. The light behind the NEUTRAL (N) symbol will blink, indicating shift in
progress. The light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is complete.
7. After the shift is completed and the NEUTRAL (N) light stays on, release the NEUTRAL (N) button.

STARTING AND OPERATING 547

Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring the vehicle to a complete stop, leaving it con-nected to the tow vehicle.
2. Apply the parking brake.
3. Turn the ignition switch to the ON/RUN position, but do not start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object, press and hold the recessed power transfer unit NEUTRAL (N) button
(located by the selector switch) for one second. 7. When the NEUTRAL (N) indicator light turns off,
release the NEUTRAL (N) button.

STARTING AND OPERATING 549

NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle. •
Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
Cooling System
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.
