2009 JEEP WRANGLER towing

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:
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
CAUTION!
Front or rear wheel lifts should not be used. Internal
damage to the transmission or transfer case will occur
if a front or rear wheel lift is used when recreational
towing.
Towing – Two-Wheel Drive Models
Recreational towing is allowed ONLY if the rear drive-
shaft is removed. See your authorized dealer or refer to
the Service Manual. Towing with the rear wheels on the
ground while the driveshaft is connected can result in
severe transmission damage.
382 STARTING AND OPERATING

Towing – Four-Wheel Drive Models
NOTE:The transfer case must be shifted into N (Neu-
tral), automatic transmission must be shifted into PARK,
and manual transmission must be placed in gear (not in
NEUTRAL) for recreational towing.
Shifting Into Neutral (N)
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle. Use the following procedure to prepare your vehicle for
recreational towing.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in N (Neutral) before recre-
ational towing to prevent damage to internal parts.
1. Turn the engine off.
2. Press the brake pedal.
3. Shift the automatic transmission into NEUTRAL or
press the clutch pedal on a manual transmission.
4. Shift the transfer case lever into N (Neutral).
5. Start the engine.
6. Shift the automatic transmission into DRIVE or the
manual transmission into gear.

WARNING!
Any procedure other than above could result in:
•Personal injury caused by electrolyte squirting out
the battery vent.
•Personal injury or property damage due to battery
explosion.
•Damage to the charging system of the booster
vehicle or of the immobilized vehicle.
•You should not try to start your vehicle by pushing
or towing.
•Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.(Continued)
WARNING! (Continued)
•During cold weather when temperatures are be-
low the freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above the
freezing point before attempting a jump-start.
EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, they are
mounted in the front and the rear.
NOTE:For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of
damage to the vehicle.
396 WHAT TO DO IN EMERGENCIES

WARNING!
•Chains are not recommended for freeing a stuck
vehicle. chains may break, causing serious injury
or death.
•Stand clear of vehicles when pulling with tow
hooks. Tow straps and chains may break, causing
serious injury.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle. Tow straps are recommended
when towing the vehicle, chains may cause vehicle
damage.
TOWING A DISABLED VEHICLE
The manufacturer recommends towing with all four
wheelsOFFthe ground. Acceptable methods are to tow
the vehicle on a flatbed or with one end of the vehicle
raised and the other end on a towing dolly.

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 drivability. 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
clickingsound 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,
402 MAINTAINING YOUR VEHICLE

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
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 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.
•Do not idle the engine for prolonged periods during
very rough idle or malfunctioning operating condi-
tions.
•Do not allow the vehicle to run out of fuel.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.7
