Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
•The tire has not been driven on when flat.
•The damage is only on the tread section of your tire
(sidewall damage is not repairable).
•The puncture is no greater than¼#(6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced imme-
diately with another Run Flat tire of identical size and
service description (Load Index and Speed Symbol).
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (spring,
summer, fall and winter). Traction levels may vary be-
tween different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with summer tires, be
aware these tires are not designed for winter or cold
driving conditions. Install winter tires on your vehicle
when ambient temperatures are less than 40°F (5°C) or if
roads are covered with ice or snow. For more informa-
tion, contact an authorized dealer.
556 STARTING AND OPERATING

•Change the engine oil and oil filter.
•Disconnect and reconnect the battery to reset the
engine controller memory.
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
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. Gasoline 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.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.
582 STARTING AND OPERATING

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•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 an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
(Continued)
WARNING!(Continued)
•Guard against carbon monoxide with proper main-
tenance. 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.
FLEXIBLE FUEL (2.4L ENGINE ONLY) — IF
EQUIPPED
E-85 General Information
The information in this section is for Flexible Fuel ve-
hicles only. These vehicles can be identified by a unique
fuel filler door label that statesEthanol (E-85) or Un-
leaded Gasoline Only.This section only covers those
subjects that are unique to these vehicles. Please refer to
the other sections of this manual for information on
features that are common between Flexible Fuel and
gasoline-only powered vehicles.
584 STARTING AND OPERATING

Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing This Vehicle Behind Another Vehicle
Recreational Towing — Front-Wheel Drive (FWD)
Models
DO NOTflat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for front-wheel drive models) is
allowed ONLY if the front wheels areOFFthe ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the front wheels onto the tow dolly.
3. Apply the parking brake. Place the transmission in
PARK.
4. Properly secure the front wheels to the dolly, following
the dolly manufacturer’s instructions.
5. Release the parking brake.
CAUTION!
Towing with the front wheels on the ground will
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
606 STARTING AND OPERATING

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the
switch bank below the radio screen.
Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE:With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating your engine by taking the
appropriate action.
•On the highways — slow down.
•In city traffic — while stopped, put transmission in
NEUTRAL, but do not increase engine idle speed.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “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
the “H” and you hear continuous chimes, turn the
engine off immediately and call for service.

WHAT TO DO IN EMERGENCIES 615

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 engine 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
supplement 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.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

616 WHAT TO DO IN EMERGENCIES

from the vehicle or tire and wheel components. Once
the sealant dries, it can easily be peeled off and
properly discarded.
•For optimum performance, make sure the valve stem
on the wheel is free of debris before connecting the Tire
Service Kit.
•You can use the Tire Service Kit air pump to inflate
bicycle tires. The kit also comes with two needles,
located in the Accessory Storage Compartment (on the
bottom of the air pump) for inflating sport balls, rafts,
or similar inflatable items. However, use only the Air
Pump Hose (7) and make sure the Mode Select Knob
(5) is in the Air Mode when inflating such items to
avoid injecting sealant into them. The Tire Service Kit
Sealant is only intended to seal punctures less than¼”
(6 mm) diameter in the tread of your vehicle.
•Do not lift or carry the Tire Service Kit by the hoses.
WARNING!
•Do not attempt to seal a tire on the side of the
vehicle closest to traffic. Pull far enough off the
road to avoid the danger of being hit when using
the Tire Service Kit.
•Do not use Tire Service Kit or drive the vehicle
under the following circumstances:
– If the puncture in the tire tread is approximately
1/4” (6 mm) or larger.
– If the tire has any sidewall damage.
– If the tire has any damage from driving with
extremely low tire pressure.
– If the tire has any damage from driving on a flat
tire.
– If the wheel has any damage.
– If you are unsure of the condition of the tire or
the wheel.
