2006 JEEP LIBERTY transmission

If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However, if
frequent shifting occurs while in this range, the “3” range
should be selected.
NOTE: Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals. NOTE:
Check the automatic transmission fluid level
before towing.
Towing Tips — O/D OFF (If Equipped)
To reduce potential for automatic transmission overheat-
ing, press the “O/D OFF” button when driving in hilly
areas or shift the transmission to Drive position 2 on
more severe grades. Refer to “Transmission Shifting” in
this section.
Towing Tips — Electronic Speed Control (If
Equipped)

Don’t 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.

Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in neutral and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
refer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing – 2WD Models
Recreational towing is not allowed. Towing with the
rear wheels on the ground can result in severe transmis-
sion damage.
Towing — 4WD Models
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.
294 STARTING AND OPERATING

NOTE:The transfer case must be shifted into N (Neu-
tral), and the transmission must be shifted into P (Park)
(for automatic transmission) or into any forward gear (for
manual transmission) for recreational towing.
Shifting Into Neutral (N)
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
recreational towing to prevent damage to internal
parts.
1. Depress brake pedal.
2. Shift transmission into N (Neutral). 3. Shift transfer case lever into N (Neutral).
4. Start engine.
5. Shift automatic transmission into D (Drive) or manual
transmission into any forward gear.
6. Release brake pedal and ensure that there is no vehicle
movement.
7. Shut the engine OFF and place the ignition key into
the unlocked OFF position.
8. Shift automatic transmission into P (Park) or ensure
manual transmission is in any forward gear.
9. Apply parking brake.
10. Attach vehicle to the tow vehicle with tow bar.
11. Release parking brake.
STARTING AND OPERATING 295

CAUTION!
Transmission damage may occur if the automatic
transmission is shifted into P (Park) with the transfer
case in N (Neutral) and the engine running. With the
transfer case in N (Neutral) ensure that the engine is
OFF prior to shifting the transmission into P (Park)
(refer to step s7–8above).
Shifting Out Of Neutral (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Shift transmission into N (Neutral).
2. Turn engine off.
3. Shift transfer case lever to desired position.
4. Shift automatic transmission into P (Park). 5. Start engine.
6. Shift automatic transmission into D (Drive) or manual
transmission into any forward gear.
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
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
296 STARTING AND OPERATING

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transmission in N
(Neutral), but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
Control to maximum heat, the Mode Control to floor, and
the Fan Control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system. If the pointer rises to the “H” (hot mark) on a vehicle
equipped with a
gasoline engine, pull over and stop the
vehicle. Do not turn the engine off. Idle the vehicle with
the air conditioning turned off, until the pointer drops
back into the normal range.CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H”,
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H”, and you hear continuous chimes, turn the
engine off immediately, and call for service.

weight of 50 lbs (23 kg) including the weight of the spare
tire.
Preparations For Jacking
Park the vehicle on a firm level surface, avoid ice or
slippery areas, set the parking brake and place auto-
matic transmission in P (Park), or manual transmission in
R (Reverse). Turn OFF the ignition.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site of the jacking position.
For example, if changing the
right front tire, block the left
rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
Jacking Instructions
1. Remove spare tire.
2. Loosen (but do not remove) the wheel lug nuts by
turning them to the left one turn while the wheel is still
on the ground.
3. Remove jack and tools from mounting bracket. As-
semble the tools by connecting the driver to the exten-
sion, and then to the lug wrench.
304 WHAT TO DO IN EMERGENCIES

JUMP STARTING — GASOLINE ENGINES
NOTE:Check the charge indicator on the battery. If the
indicator is light or yellow, replace the battery.
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
unintended electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach but
without letting the vehicles touch. Set the parking brake,
place the automatic transmission in P (Park), or manual
transmission in N (Neutral), and turn the ignition to OFF
for both vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads. 4. Connect one end of a jumper cable to the positive
terminal of the discharged battery. Connect the other end
of the same cable to the positive terminal of the booster
battery.
5. Connect the other cable, first to the negative terminal
of the booster battery and then connect the other end to
a non-paint metal surface on the engine of the vehicle
with the discharged battery. Make sure you have a good
contact on the engine.
6. Start the engine in the vehicle which has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
7. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.

TOWING A DISABLED VEHICLE
2WD Models Only
Provided the transmission is operable, tow only in N
(Neutral) at speeds not exceeding 30 mph (48 km/h), for
distances of not more than 15 miles (24 km). Towing at
more than 30 mph (48 km/h) or for more than 15 miles
(24 km) can cause severe transmission damage. If the
transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 15
miles (24 km), tow with all four wheels OFFthe 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. Removing the driveshaft for towing is not
recommended since this can allow fluid to drain from the
transmission.
4WD Models Only
The manufacturer recommends towing with all four
wheels OFFthe 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.
