air conditioning JEEP COMMANDER 2009 1.G User Guide

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, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
SNOW PLOW
Snow plows, winches, and other aftermarket equipment
shouldnotbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.
WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing – 2WD Models
Recreational towing is allowed ONLY if the driveshaft
is removed.Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
392 STARTING AND OPERATING

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
switch bank just above the climate controls.
Press the switch to turn on the Hazard
Warning flashers. When the Hazard
Warning flasher switch is activated, all
directional turn signals will flash on
and off to warn oncoming traffic of an
emergency. Press the switch a second
time to turn off flashers.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flasher will continue to operate with the
ignition key removed and the vehicle locked.NOTE:With extended use, the Hazard Warning flasher
may run down your battery.
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
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
400 WHAT TO DO IN EMERGENCIES

WARNING! (Continued)
•The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced repairman.
NOTE:Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, and Refrigerants.
Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency (EPA) and is an ozone-saving product.
However, the manufacturer recommends that air condi-
tioning service be performed by authorized dealers or
other service facilities using recovery and recycling
equipment.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be lubri-
cated periodically with a lithium based grease such as
MOPARSpray White Lube to assure quiet, easy opera-
tion and to protect against rust and wear. Prior to the
application of any lubricant, the parts concerned should
be wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant such as MOPAR
Lock Cylinder Lubricant directly into the lock cylinder.

•Make sure that the radiator and coolant recovery
bottle hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance, poor gas
mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be periodically inspected.
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the brake system warning lamp indicates system
failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” dot and a “MIN” dot. The fluid level must be
kept within these two dots. Do not add fluid above the
MAX mark, because leakage may occur at the cap.

•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
