Attach  T-hook  chains  on 
both sides in the  slotted 
holes 
in the underbody just 
ahead of the wheels. 
I NOTICE: 
Do not  tow  with  sling-type  equipment  or rear 
bumper  valance  will  be  damaged.  Use  wheel-lift 
or  carcarrier  equipment  (additional  ramping 
may 
be required for car-carrier  equipment).  Use 
safety  chains  and wheel  straps. 
I NOTICE: 
Do not  have  your  vehicle  towed  with  the front 
wheels  in  contact  with  the  ground.  This 
will 
damage  the  transaxle. If the  vehicle  must  be 
towed  on  the front  wheels,  it cannot  be  towed 
more  than 
a total of 500 miles (800 km) for the 
lifetime  of the  vehicle.

NOTICE: 
Towing a vehicle  over  rough  surfaces  could 
damage  a  vehicle.  Damage  can  occur  from  vehicle  to  ground 
or vehicle  to wheel-lift 
equipment. 
To help  avoid  damage,  install  a 
towing  dolly  and raise  the  vehicle  until  adequa  .te 
clearance 
is obtained  between  the  ground  and/or 
wheel-lift  equipment. 
Do  not  attach  winch  cables 
or J-hooks  to 
suspension  components  when  using  carcarrier 
equipment.  Always  use  T-hooks  inserted  in 
the T-hook slots. 
Attach  a  separate  safety  chain  to  each  side 
of the 
axle inboard of the  spring.

Engine Overheating 
You will  find  a  coolant  temperature  gage  and  a  low 
cooIant  warning  light 
on your vehicle’s  instrument 
panel.  See “Engine  Coolant  Temperature  Gage” 
and 
“Low  Coolant  Warning  Light” in the  Index. 
If Steam Is Coming From Your Engine 
A CAUTION: 
Steam  from an overheated  engine  can  burn you 
badly,  even 
if you  just  open  the  hood.  Stay  away 
from  the  engine  if  you  see or  hear steam  coming 
from  it.  Just  turn  it 
off and  get  everyone  away 
from  the  vehicle  until  it 
cools down. Wait  until 
there 
is no  sign  of  steam  or coolant  before  you 
open  the 
hood. 
If you keep driving when your engine is 
overheated,  the  liquids  in it can catch  fire. You or 
others  could  be  badly  burned.  Stop  your  engine 
if 
it  overheats, and get  out of the vehicle  until  the 
engine 
is cool. 
I NOTICE: I 
If your  engine  catches  fire because  you keep 
driving 
with no coolant,  your  vehicle  can  be 
badly damaged.  The  costly  repairs would  not  be 
covered 
by your  warranty.

If No Steam Is Coming From Your Engine 
If  you  get  the  overheat  warning  but see  or  hear  no 
steam,  the  problem  may  not be  too  serious.  Sometimes 
the  engine  can  get  a  little  too  hot  when  you: 
0 Climb  a  long  hill  on a  hot  day. 
Stop  after  high-speed  driving. 
Idle  for  long  periods  in  traffic. 
Tow  a  trailer. 
If  you  get  the  overheat  warning  with  no  sign 
of steam, 
try 
this for  a  minute  or so: 
1. If  you  have  an  air  conditioner, turn it off. 
?. Turn on  your  heater  to  full  hot  at  the  highest  fan 
speed  and  open  the  window  as  necessary. 
3. If  you’re  in  a  traffic jam, shift  to  NEUTRAL (N); 
otherwise,  shift  to  the  highest  gear  while 
driving 
-- AUTOMATIC  OVERDRIVE (a) or 
THIRD (3) for  automatic  transaxles. 
If you no longer  have  the  overheat  warning,  you 
can  drive.  Just  to  be  safe,  drive  slower  for about 
10 minutes.  If the  warning  doesn’t  come  back  on, 
you  can  drive  normally. 
If  the  warning  continues,  pull  over,  stop, 
and park  your 
vehicle  right  away. 
If  there’s  still 
no sign of steam,  you  can  idle  the  engine 
for  two  or  three  minutes  while  you’re  parked,  to  see  if 
the  warning  stops.  But  then,  if  you  still  have  the 
warning, 
turn  o@the  engine and get  everyone out of the 
vehicle 
until  it  cools  down. 
You  may  decide  not  to  lift  the hood  but  to get  service 
help  right  away.

Cooling System 
When  you decide  it’s  safe  to  lift  the  hood,  here’s  what 
you 
’11 see: 
2.4L Engine 
3100 Engine 
A. Coolant  Surge Tank with  Pressure Cap 
B. Electric  Engine  Cooling  Fan 
5-16  
Page 216 of 370
A CAUTION: 
An electric  engine  cooling fan under  the  hood  can 
start up even  when  the  engine is not  running  and 
can  injure  you. 
Keep hands,  clothing  and  tools 
away  from  any  underhood  electric 
fan. 
If the  coolant  inside  the  coolant  surge  tank  is  boiling, 
don’t 
do anything  else  until  it  cools  down. 
I 
The  coolant  level should be at or above FULL COLD. 
If it  isn’t,  you  may  have  a leak  in  the  radiator  hoses, 
heater  hoses,  radiator,  water  pump  or  somewhere  else  in 
the cooling system. 
5-17  
Page 217 of 370
LA CAUTION: I 
-1 - 
Heater  and  radiator hoses, and  other  engine 
parts,  can  be  very hot. Don’t  touch them. 
If you 
do,  you  can  be  burned. 
Don’t  run  the  engine 
if there is a leak. If you run 
the 
engine, it could lose  all coolant.  That could 
cause  an engine 
fire, and  you could be burned. 
Get 
any leak fixed  before  you drive  the  vehicle. 
NOTICE: 
Engine damage  from  running  your  engine 
without  coolant  isn’t covered 
by your  warranty. 
If there  seems  to  be  no  leak,  with  the  engine on, check  to 
see if the electric  engine  cooling fan is running. If the 
engine is overheating, the fan should  be  running. If it 
isn’t,  your  vehicle  needs  service. 
How to Add Coolant  to the Coolant 
Surge Tank 
If you  haven’t  found  a  problem  yet,  but  the coolant level 
isn’t at or  above FULL COLD, add  a 50/50 mixture of 
clean water (preferably  distilled)  and DEX-COOL@ 
coolant  at the coolant  surge tank, but  be sure the  cooling 
system,  including  the coolant  surge 
tank pressure  cap, is 
cool  before  you  do  it.  (See  “Engine Coolant” in the 
Index  for more  information.) 
’ /$ CAUTION: 
- 
Steam and scalding  liquids  from a hot  cooling 
system 
can blow  out  and  burn  you badly. They 
are  under pressure, and if you turn  the  coolant 
surge 
tank pressure  cap -- even a little -- they 
can  come  out 
at high speed. Never  turn  the  cap 
when  the cooling  system,  including  the coolant 
surge 
tank pressure  cap, is hot.  Wait  for  the 
cooling  system and coolant  surge 
tank pressure 
cap to cool if you ever  have  to turn  the 
pressure  cap.

b. - A CAUTION: 
I - 
Adding  only  plain  water to your  cooling  system 
can  be  dangerous.  Plain  water,  or some  other 
liquid  like  alcohol,  can  boil  before  the  proper  coolant  mixture  will.  Your  vehicle’s  coolant 
warning  system 
is set for the  proper  coolant 
mixture.  With  plain  water  or the  wrong  mixture, 
your engine  could  get  too  hot  but you wouldn’t 
get  the  overheat  warning.  Your  engine  could 
catch 
fire and  you or others  could  be  burned. 
Use  a 
50/50 mixture  of clean  water  and 
DEX-COOL@ coolant. 
5-19  
Page 219 of 370
I NOTICE: I 
In cold  weather,  water  can  freeze  and  crack  the 
engine,  radiator,  heater 
core and other  parts. So 
use  the  recommended  coolant. 
/d CAUTION: 
You can be burned if you  spill  coolant  on  hot 
engine  parts.  Coolant  contains  ethylene  glycol 
and  it 
will burn if the  engine parts are hot 
enough.  Don’t  spill  coolant  on 
a hot  engine. -1

1. You can  remove  the coolant  surge  tank  pressure  cap 
when  the cooling  system,  including  the coolant surge 
tank pressure  cap and upper  radiator  hose, is no 
longer  hot. 
Turn the  pressure  cap  slowly  about 
one-quarter 
turn to  the  left  and  then stop. 
If you hear  a  hiss,  wait  for that  to  stop. A hiss means 
there 
is still  some  pressure  left.

2. Then  keep  turning  the  pressure  cap  slowly, and 
remove  it. 
3. Then fill the  coolant  surge  tank with the proper 
mixture,  up to FULL COLD, or  just  above  the  small 
cylinder  at 
the base of the opening.
