232IN CASE OF EMERGENCY
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
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, not the ACC
mode.
If the key fob is unavailable, or the vehicle's
battery is discharged, refer to "Manual Park
Release" in this section for instructions on
shifting the transmission out of PARK for
towing.

IN CASE OF EMERGENCY233
REAR-WHEEL DRIVE (RWD) MODELS
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground
using a flatbed. If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
flat towed (with all four wheels on the ground)
under the following conditions:
The transmission must be in NEUTRAL. Refer
to "Manual Park Release" in this section for
instructions on shifting the automatic trans
-
mission to NEUTRAL when the engine is off.
The towing distance must not exceed
30 miles (48 km).
The towing speed must not exceed 30 mph
(48 km/h).
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km),
then the only acceptable method of towing is
with a flatbed truck.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
Please refer to “Occupant Restraint Systems” in
“Safety” for further information on the
Enhanced Accident Response System (EARS)
function.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is
to record data that will assist in understanding
how a vehicle’s systems performed under
certain crash or near crash-like situations, such
as an air bag deployment or hitting a road
obstacle.
Please refer to “Occupant Restraint Systems” in
“Safety” for further information on the Event
Data Recorder (EDR).
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 suspen -
sion components. Damage to your vehicle
may result from improper towing.
The manufacturer does not recommend
towing this vehicle using a tow dolly.
Vehicle damage may occur.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe engine and/
or transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.

262SERVICING 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.
To minimize the possibility of catalytic converter
damage:
Do not shut off the engine or interrupt the
ignition when the transmission is in gear and
the vehicle is in motion.
Do not try to start the engine by pushing or
towing the vehicle.
Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.
NOTE:
The vehicle exhaust system may be equipped
with an Electronic Exhaust Valve (EEV) system,
if the exhaust system is replaced with after -
market products a Malfunction Indicator Lamp
(MIL) will illuminate.
COOLING SYSTEM
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If coolant is dirty or
rusty in appearance, the system should be
drained, flushed, and refilled with fresh coolant.
Check the front of the radiator for any
accumulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the coolant recovery bottle tubing for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the bottle and
radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
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 open a cooling system pressure
cap when the radiator or coolant bottle is
hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts automati -
cally and may start at any time, whether the
engine is running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the
ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.
WARNING! (Continued)

SERVICING AND MAINTENANCE267
CLUTCH HYDRAULIC SYSTEM — MANUAL
T
RANSMISSION (IF EQUIPPED)
The clutch hydraulic system is fed by a
segregated volume of fluid within the brake
system master cylinder reservoir. In the event of
leakage or wear, use only the manufacturer's
recommended brake fluid. Refer to “Fluids And
Lubricants” in “Technical Specifications” for
further information.
MANUAL TRANSMISSION — IF EQUIPPED
Fluid Level Check
Check the fluid level by removing the fill plug on
the left side of the transmission. The fluid level
should be 1/4 inch (6.4mm) below the bottom
of the fill hole. Add fluid, if necessary, to
maintain the proper level. Refer to “Fluids And
Lubricants” in “Technical Specifications” for
further information.
Change Transmission Fluid
If contaminated with water, change the fluid
immediately. See an authorized dealer for
service.
Refer to the “Maintenance Plan” in this section
for the proper maintenance intervals.
AUTOMATIC TRANSMISSION — IF
E
QUIPPED
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only the
manufacturer's specified transmission fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications. It is
important to maintain the transmission fluid at
the correct level using the recommended fluid.
NOTE:
No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
Special Additives
The manufacturer strongly recommends
against using any special additives in the
transmission. Automatic Transmission Fluid
(ATF) is an engineered product and its
performance may be impaired by supplemental
additives. Therefore, do not add any fluid
additives to the transmission. Avoid using
transmission sealers as they may adversely
affect seals.
CAUTION!
Using a transmission fluid other than the
manufacturer's recommended fluid may
cause deterioration in transmission shift
quality and/or damage to the transmission.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
