engine JEEP WRANGLER 2009 JK / 3.G User Guide

A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not inter-
preted as an indication of difficulty.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
•It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seri-
ously injured or killed.(Continued)
WARNING! (Continued)
•Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat
belts.
•Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow these safety tips:
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.
If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate open,
make sure that all windows are closed and the climate
control BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle isdamaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
Safety Checks You Should Make Inside the
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION!
In cold weather, always turn off the wiper switch and
allow the wipers to return to the park position before
turning off the engine. If the wiper switch is left on
and the wipers freeze to the windshield, damage to
the wiper motor may occur when the vehicle is
restarted.

Tapping RESUME ACCEL once will result ina1mph
(1.6 km/h) speed increase. Each time the Electronic
Speed Control lever is tapped, speed increases so that
tapping the Electronic Speed Control lever three times
will increase speed by 3 mph (4.8 km/h), etc.
To decrease speed while the Electronic Speed Control is
set, push down and hold the SET DECEL lever. If the
lever is continually held in the SET DECEL position, the
set speed will continue to decrease in 5 mph (10 km/h)
increments until the lever is released. Release the lever
when the desired speed is reached, and the new set speed
will be established.
Tapping the SET DECEL button once will result in a
1 mph (1.6 km/h) speed decrease. Each time the button is
tapped, speed decreases.
Manual Transmission
Pressing the clutch pedal will disengage the Electronic
Speed Control. A slight increase in engine RPM before the
Electronic Speed Control disengages is normal.Vehicles equipped with manual transmissions may need
to be shifted into a lower gear to climb hills without
speed loss.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your vehicle
could go too fast for the conditions, and you could lose
control. An accident could be the result. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.
To Accelerate for Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.

The right-side power outlet is powered directly from the
battery (power available at all times). Items plugged into
this power outlet may discharge the battery and/or
prevent the engine from starting.
WARNING!
To avoid serious injury or death:
•Only connectors designed for use in this type of
outlet should be inserted into any 12 Volt outlet.
•Do not touch with wet hands.
•Close the lid when not in use and while driving
the vehicle.
•If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
•Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not in
use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
•After the use of high-power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
alternator to recharge the vehicle’s battery.(Continued)
