structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode.
If the key fob is unavailable or the vehicle’s battery is
discharged, refer to “Gear Selector Override” in this section
for instructions on shifting the automatic transmission out
of PARK for towing.
CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
Automatic Transmission
The manufacturer recommends towing your vehicle with
all four wheels OFFthe ground using a flatbed. If flatbed equipment is not available, and the transmission
is operable, this vehicle may be towed (with front wheels
on the ground) under the following conditions:
•
The transmission must be in NEUTRAL.
• The towing speed must not exceed 25 mph (40 km/h).
• The towing distance must not exceed 15 miles (24 km).
If the transmission is not operable, or the vehicle must be
towed faster than 25 mph (40 km/h) or farther than 15
miles (24 km), tow with the front wheels OFFthe ground
(using a flatbed truck, or wheel lift equipment with the
front wheels raised).
CAUTION!
• Towing faster than 25 mph (40 km/h) or farther than
15 miles (24 km) with front wheels on the ground can
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
• Towing this vehicle in violation of the above require-
ments can cause severe transmission damage. Dam-
age from improper towing is not covered under the
New Vehicle Limited Warranty.

IN CASE OF EMERGENCY 221

Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is an ozone-saving product. However,
the manufacturer recommends that air conditioning ser-
vice be performed by authorized dealer or other service
facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.
Cabin Air Filter (A/C Air Filter)
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals.
WARNING!
Do not remove the cabin air filter while the vehicle is
running, or while the ignition is in the ACC or ON/
RUN mode. With the cabin air filter removed and the
blower operating, the blower can contact hands and
may propel dirt and debris into your eyes, resulting in
personal injury. The cabin air filter is located in the fresh air inlet in the
engine compartment. Perform the following procedure to
replace the filter:
1. Remove the two screws that secure the filter retainer to
the fresh air inlet, and remove the filter retainer.

SERVICING AND MAINTENANCE 235

Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has limited
driving capabilities and needs to be replaced immediately.
A Run Flat tire is not repairable. When a run flat tire is
changed after driving with underinflated tire condition,
please replace the TPM sensor as it is not designed to be
reused when driven under run flat mode (14 psi (96 kPa))
condition.
NOTE:TPM Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring section for more informa-
tion.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of Emer-
gency” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause tire damage or
failure. A tire could explode and injure someone. Do
not spin your vehicle’s wheels faster than 30 mph
(48 km/h) for more than 30 seconds continuously when
you are stuck, and do not let anyone near a spinning
wheel, no matter what the speed.
Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be re-
placed.
258 SERVICING AND MAINTENANCE

Do Not Use E-85 In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 15% ethanol (E-15). Use of gasoline with
higher ethanol content may void the New Vehicle Limited
Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,
the engine will have some or all of these symptoms:
•Operate in a lean mode.
• OBD II Malfunction Indicator Light on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on Compressed
Natural Gas (CNG) or Liquid Propane (LP) may result in
damage to the engine, emissions, and fuel system compo-
nents. Problems that result from running CNG or LP are
not the responsibility of the manufacturer and may void or
not be covered under the New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT) is
a manganese-containing metallic additive that is blended
into some gasoline to increase octane. Gasoline blended
with MMT provides no performance advantage beyond
gasoline of the same octane number without MMT. Gaso-
line blended with MMT reduces spark plug life and
reduces emissions system performance in some vehicles.
The manufacturer recommends that gasoline without
MMT be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline pump;
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.

STEERING WHEEL AUDIO CONTROLS
The remote sound system controls are located on the
surface of the steering wheel.
The right-hand control is a rocker-type switch and controls
the SCAN functions of the sound system.
The left-hand control is a rocker-type switch and controls
the volume of the sound system plus a button to mute the
Sound System.
The following describes the right-hand control operation in
each mode.
Radio Operation
Pushing the top of the switch will “Scan” up for the next
listenable station and pushing the bottom of the switch will
“Scan” down for the next listenable station.
Player Operation
Pushing the switch up once will go to the next track on the
Player. Pushing the switch down once will go to the
beginning of the current track, or to the beginning of the
previous track if it is within one second after the current
track begins to play.
If you push the switch up or down twice, it plays the
second track; three times, it will play the third, etc.
IPOD/USB/MP3 CONTROL — IF EQUIPPED
The USB Port and Auxiliary Jack is located on the instru-
ment panel left of the radio (driver ’s lower right). This
feature allows an iPod or external USB device to be
plugged into the USB port.Remote Sound System Controls
