2014 JEEP WRANGLER towing

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws regarding
vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the vehicle’s battery is discharged, refer to “Shift Lever
Override” in this section for instructions on shifting the
automatic transmission out of PARK for towing.CAUTION!
Do not use sling type equipment when towing.
When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. The only ap-
proved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.

WHAT TO DO IN EMERGENCIES 575

Four–Wheel Drive Models
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of the vehicle raised
and the opposite end on a towing dolly.
If flatbed equipment is not available and the transfer case
is operable, the vehicle may be towed (in the forward
direction, with ALLwheels on the ground), IFthe
transfer case is in NEUTRAL(N) and the transmission is
in PARK (for automatic transmissions) or in gear ( NOT
in NEUTRAL, for manual transmissions). Refer to “Rec-
reational Towing” in “Starting And Operating” for de-
tailed instructions.
CAUTION!
• Front or rear wheel lifts must not be used. Internal
damage to the transmission or transfer case will
occur if a front or rear wheel lift is used when
towing.
• Towing this vehicle in violation of the above re-
quirements can cause severe transmission and/or
transfer case damage. Damage from improper tow-
ing is not covered under the New Vehicle Limited
Warranty.
576 WHAT TO DO IN EMERGENCIES

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 automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions 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. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emissions
tests can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improp-
erly installed, or damaged. A “gASCAP” message will be
displayed in the odometer. Tighten the gas cap until a
clicking sound is heard. This is an indication that the
gas cap is properly tightened. Press the odometer reset
button to turn the message off. If the problem persists,
580 MAINTAINING YOUR VEHICLE

To minimize the possibility of catalytic converter dam-
age:
•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.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser (if
equipped) or radiator for any accumulation of bugs,

Transfer Case We recommend you use MOPAR® ATF+4® Automatic Transmission Fluid.
Axle Differential (Front) We recommend you use MOPAR® Gear & Axle Lubricant (SAE 80W-90)
(API GL-5).
Axle Differential (Rear) 226 RBI (Model 44)– We recommend you use MOPAR® Gear & Axle
Lubricant (SAE 80W-90) (API GL-5) or equivalent. For trailer towing, use
MOPAR® Synthetic Gear & Axle Lubricant (SAE 75W-140). Models
equipped with Trac-Lok™ require an additive.
