2007 JEEP WRANGLER climate control

A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
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 the safety tips below.
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.

6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being ON in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
Manual Heater Only
The controls for the heating/ventilation system in this
vehicle consist of a series of rotary knobs. These comfort
controls can be set to obtain desired interior conditions.

Trac-Lok™ is especially helpful during slippery driving
conditions. With both rear wheels on a slippery surface, a
slight application of the accelerator will supply maxi-
mum traction.
WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground. The vehicle may drive through the rear
wheel remaining on the ground and cause you to lose
control of your vehicle.

NOTE:The indicator lights will flash until the axles are
fully locked or unlocked.
To unlock the axles, push the top of the switch.
Axle lock will disengage if the vehicle is taken out of 4L
(Low) range, or the ignition switch is turned to the OFF
position.
REAR AXLE LOCK — 4WD NON-RUBICON
MODELS (IF EQUIPPED)
The rear axle lock switch is located on the lower switch
bank (below the climate controls).
This feature will only activate when the following con-
ditions are met:
•Key in ignition, vehicle in 4L (Low) range.
•Vehicle speed should be 10 mph (16 km/h) or less.
To activate the system, press the switch down to lock the
rear axle (the “Rear Axle Lock Indicator Light” will
illuminate), press the switch up to unlock the rear axle.

ELECTRONIC SWAY BAR DISCONNECT — IF
EQUIPPED
Your vehicle may be equipped with an electronic discon-
necting stabilizer/sway bar. This system allows greater
front suspension travel in off-road situations.
This system is controlled by the electronic control sway
bar switch located on the lower switch bank (below the
climate controls).
Press the sway bar switch to activate the system. Press
the switch again to deactivate the system. The “Sway Bar
Indicator Light” (located in the instrument cluster) will

HAZARD WARNING FLASHERS
Your vehicle’s hazard warning flasher is an emergency
warning system. When you activate it, all front and rear
directional signals will flash intermittently. Use it when
your vehicle is disabled on or near the road. It warns
other drivers to steer clear of you and your vehicle. This
is an emergency warning system, not to be used when the
vehicle is in motion.
To activate the warning flashers, press the button on the
lower switch bank (below the climate controls). To turn
the warning flashers off, press the button again.
NOTE:With extended use, the flasher may wear down
your battery.

TIRE QUALITY GRADES
The following describes the tire grading categories estab-
lished by the National highway Traffic Safety Adminis-
tration. The specific grade rating assigned by the tire’s
manufacturer in each category is shown on the sidewall
of the tires on your car.
All Passenger Car Tires Must Conform to Federal Safety
Requirements in Addition to These Grades.
Treadwear
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled con-
ditions on a specified government test course. For ex-
ample, a tire graded 150 would wear one and a half (1
1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, andmay depart significantly from the norm due to variations
in driving habits, service practices and differences in road
characteristics and climate.
Traction Grades
The traction grades, from highest to lowest, are AA, A, B,
and C. Those grades represent the tire’s ability to stop on
wet pavement as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor-
mance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
