2007 JEEP WRANGLER parking brake

Gear Ranges
DO NOT race the engine when shifting from P (Park) or
N (Neutral) position into another gear range.
P (Park)
This gear position supplements the parking brake by
locking the transmission. The engine can be started in
this range. Never use P (Park) while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range. Always apply parking brake first,
then place the selector in P (Park) position.
WARNING!
Never use P (Park) position as a substitute for the
parking brake. Always apply parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
WARNING!
It is dangerous to shift the selector lever out of P
(Park) or N (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your right foot is firmly on the brake pedal.
276 STARTING AND OPERATING

R (Reverse)
Use this range only after the vehicle has come to a
complete stop.
N (Neutral)
Shift into N (Neutral) when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with selector lever in N (Neutral) can result
in severe transmission damage. Refer to “Recreational
Towing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.Overdrive (O/D)
For most city and highway driving. The transmission
contains an electronically controlled Overdrive, and will
automatically shift from D (Drive) to O/D (Overdrive) if
the following conditions are present:
•The transmission selector is in D (Drive).
•The O/D OFF switch has not been activated.
•Vehicle speed is above approximately 30 mph (48
km/h).

WARNING!
Never use P (Park) position with an automatic trans-
mission as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
CAUTION!
•Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK so the steering
wheel and shift lever are released. Otherwise,
damage to steering column or shifter could result.
•Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These prac-
tices can overheat and damage the transmission.
•When “rocking” a stuck vehicle by moving be-
tween D (Drive) and R (Reverse), do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.

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.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position, see the information below:
2H Position
Rear Wheel Drive High Range — Normal street and
highway driving. Hard surfaced roads.
4H Position
Four Wheel Drive High Range — Locks the front and rear
driveshafts together. Forces the front and rear wheels to
rotate at the same speed. This range (4H) provides
additional traction for loose, slippery road surfaces and
should not be used on wet or dry pavement.
WARNING!
Do not drive this vehicle in excess of 50 mph (80
km/h) with the transfer case in the four wheel drive
high range (4H). Failure to follow this warning can
result in loss of control and an accident causing
serious and fatal injuries.
282 STARTING AND OPERATING

PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the “Brake Warning Light” in the instru-
ment cluster will light. To release the parking brake, pull
up slightly, press the center button, then lower the lever
completely.
NOTE:The instrument cluster “Brake Warning Light”
indicates only that the parking brake is applied. You must
be sure the parking brake is fully applied before leaving
the vehicle.
Be sure the parking brake is firmly set when parked, and
the gear shift lever is in the P (Park) position (automatic
transmission) or R (Reverse) or 1st gear (manual trans-
mission). When parking on a hill, you should apply the
parking brake before placing the gear shift lever in P

(Park), otherwise the load on the transmission locking
mechanism may make it difficult to move the selector out
of P (Park).
WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury. Also, be certain to leave an automatic
transmission in P (Park), a manual transmission in
R (Reverse) or 1st gear. Failure to do so may allow
the vehicle to roll and cause damage or injury.
•Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Do not leave the keys
in the ignition. A child could operate power win-
dows, other controls, or move the vehicle.When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
ANTI-LOCK BRAKE SYSTEM
The Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lock-up and help avoid skidding on slippery surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
296 STARTING AND OPERATING

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
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 an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P (Park). With a manual transmission, shift the trans-
mission into 1st gear. And with four-wheel-drive ve-
hicles, make sure the transfer case is not in N (Neu-
tral). Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR

4. Start engine.
5. Shift automatic transmission into D (Drive) or manual
transmission into 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
ACC position.
8. Shift automatic transmission into P (Park).

Damage to the transmission may occur if the trans-
mission 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 steps 7 – 8 above).
Shifting Out Of Neutral (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Shift automatic transmission into N (Neutral) or de-
press clutch pedal on manual transmission.
2. Shift transfer case lever into desired position.
