238 IN CASE OF EMERGENCY
NOTE:
Push the “ESC OFF” switch, to place the Electronic Stability
Control (ESC) system in “Partial Off” mode, before rocking
the vehicle. Refer to “Electronic Brake Control System” in
“Safety” for further information. Once the vehicle has been
freed, push the “ESC OFF” switch again to restore “ESC On”
mode.
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster
than 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping when you are stuck and
do not let anyone near a spinning wheel, no matter what
the speed.
CAUTION!
• 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 occurring).

254 SERVICING AND MAINTENANCE
(Continued)
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to ensure 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
• Fuel Economy
• Tread Wear
• Ride Comfort and Vehicle Stability
Safety
Both underinflation and overinflation 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.
