System refer to “Refueling The Vehicle” in
“Starting And Operating ” in this manual.
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place thetransmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes. NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it
off. The A/C system adds heat to the en-
gine cooling system and turning the A/C
off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine 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.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (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 HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully apply-
ing the parking brake, before activating
the Manual Park Release. Activating the
Manual Park Release will allow your ve-
hicle to roll away if it is not secured by the
parking brake or by proper connection to a
tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could
lead to serious injury or death for those in
or around the vehicle.
IN CASE OF EMERGENCY
224

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand
or snow, it can often be moved using a rock-
ing motion. Turn the steering wheel right and
left to clear the area around the front wheels.
Push and hold the lock button on the gear
selector. Then shift back and forth between
DRIVE and REVERSE while gently pressing
the accelerator.
NOTE:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal
pressure that will maintain the rocking mo-
tion without spinning the wheels or racing the
engine.NOTE:
Push the "ESC Off" switch (if necessary), to
place the Electronic Stability Control (ESC)
system in "Partial Off" mode, before rocking
the vehicle. Refer to “Electronic Brake Con-
trol” in “Safety” in the Owners Manual at
www.jeep.com/en/owners/manuals/ for fur-
ther information. Once the vehicle has been
freed, push the "ESC Off" switch again to
restore "ESC On" mode.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your
vehicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
transmission failure during prolonged
efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE and REVERSE, do
not spin the wheels faster than 15 mph
(24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
IN CASE OF EMERGENCY

SCHEDULED SERVICING
NON-SRT
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel
usage will influence when the “Oil Change
Required” message is displayed. Severe op-erating conditions can cause the change oil
message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
twelve months or 350 hours of engine run
time, whichever comes first. The 350 hours
of engine run or idle time is generally only a
concern for fleet customers. Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look
for unusual wear or damage.
• Check the fluid levels of the coolant reser- voir, brake master cylinder and fill as

off the glass unless the wiper arm pivot
cap is unsnapped first. Attempting to fully
raise the rear wiper arm without unsnap-
ping the wiper arm pivot cap may damage
the vehicle.
2. Lift the rear wiper arm fully off the glass.
3. Insert the wiper blade pivot pin into the opening on the end of the wiper arm. Grab
the bottom end of the wiper arm with one
hand, and press the wiper blade flush with
the wiper arm until it snaps into place.
4. Lower the wiper blade onto the glass and snap the wiper arm pivot cap back into
place.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) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty, the sys-
tem should be drained, flushed, and refilled
with fresh OAT coolant (conforming to
MS.90032) by an authorized dealer. Check the front of the A/C condenser for any accu-
mulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the coolant
recovery bottle and radiator. Inspect the en-
tire system for leaks.
With the engine at normal operating tempera-
ture (but not running), check the cooling
system pressure cap for proper vacuum seal-
ing by draining a small amount of engine
coolant (antifreeze) from the radiator drain
cock. If the cap is sealing properly, the engine
coolant (antifreeze) will begin to drain from
the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.

B-Pillar The vehicle B-Pillar is the structural member of the body located behind the front
door.
Cold Tire Inflation Pressure Cold tire inflation pressure is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1 mile (1.6 km) after sitting
for a minimum of three hours. Inflation pressure is measured in units of PSI (pounds
per square inch) or kPa (kilopascals).
Maximum Inflation Pressure The maximum inflation pressure is the maximum permissible cold tire inflation pres-
sure for this tire. The maximum inflation pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer's recommended cold tire inflation pressure as shown on the tire
placard.
