IN CASE OF EMERGENCY 495
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
If the transmission and drivetrain are operable, disabled
vehicles may also be towed as described under “Recreational
Towing” in the “Starting And Operating” section.
NOTE:
Vehicles equipped with the Air Suspension System must be
placed in Transport mode, before tying them down (from the
body) on a trailer or flatbed truck. If the vehicle cannot be
placed in Transport mode (for example, engine will not run),
tie-downs must be fastened to the axles (not to the body).
Failure to follow these instructions may cause fault codes to
be set and/or cause loss of proper tie-down tension.
Refer to "Air Suspension System — If Equipped" in "Starting
And Operating" for more information.
CAUTION!
• Racing the engine or spinning the wheels may lead to transmission overheating and failure. Allow the engine
to idle with the transmission in NEUTRAL for at least
one minute after every five rocking-motion cycles. This
will minimize overheating and reduce the risk of trans -
mission failure during prolonged efforts to free a stuck
vehicle.
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast may lead to transmission overheating and failure. It can also
damage the tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission shifting occur -
ring).

SERVICING AND MAINTENANCE 521
(Continued)
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE:
Intentional tampering with emissions control systems can
result in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer's specifications, should
be obtained immediately.
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 eventu -
ally poison you. To avoid breathing CO, refer to “Safety
Tips” in “Safety” for further information.
• A hot exhaust system can start a fire if you park over materials that can burn. Such materials might be grass
or leaves coming into contact with your exhaust system.
Do not park or operate your vehicle in areas where your
exhaust system can contact anything that can burn.
CAUTION!
• The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effective -
ness of the catalyst as an emissions control device and
may seriously reduce engine performance and cause
serious damage to the engine.
• Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the
event of engine malfunction, particularly involving
engine misfire or other apparent loss of performance,
have your vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction could
cause the converter to overheat, resulting in possible
damage to the converter and vehicle. CAUTION!

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and satis-
factory operation of your vehicle. Four primary areas are
affected by improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
Both under-inflation and over-inflation affect the stability of
the vehicle and can produce a feeling of sluggish response or
over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause erraticand unpredictable steering response.
• Unequal tire pressure from side to side may cause the vehicle to drift left or right.
WARNING!
• Improperly inflated tires are dangerous and can cause collisions.
• Underinflation increases tire flexing and can result in overheating and tire failure.
• Overinflation reduces a tire's ability to cushion shock. Objects on the road and chuckholes can cause damage
that result in tire failure.
• Overinflated or underinflated tires can affect vehiclehandling and can fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause steering problems. You could lose control of your vehicle.
• Unequal tire pressures from one side of the vehicle to the other can cause the vehicle to drift to the right or
left.
• Always drive with each tire inflated to the recom -
mended cold tire inflation pressure.
