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. 
The coolant  level  should  be  at the ADD mark. 
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. 
NOTICE: 
Engine damage from running your engine 
without coolant  isn’t  covered  by  your warranty. 
If there seems  to  be no  leak,  start the engine  again.  See 
if the fan  speed increases  when  idle speed  is  doubled  by 
pushing  the accelerator pedal  down. 
If it doesn’t, your 
vehicle needs  service. 
Turn off the  engine.

How to Add Coolant  to  the  Coolant 
Recovery  Tank 
If you haven’t found a problem yet,  but the coolant  level 
isn’t  at the 
ADD mark, add a 50/50 mixture of clean 
water (preferably distilled) and DEX-COOL TM 
(silicate-free)  antifreeze at  the coolant recovery  tank. 
(See  “Engine  Coolant’’  in the Index for more 
information.) 
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  mix  will. Your  vehicle’s  coolant  warning 
system  is  set  for  the  proper  coolant  mix. With 
plain  water  or  the  wrong  mix, 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 mix  of clean 
water  and 
DEX-COOL coolant. 
I NOTICE: 
In  cold  weather,  water  can  freeze  and  crack  the 
engine,  radiator,  heater  core  and  other  parts. 
Use  the  recommended  coolant  and  the  proper 
coolant  mix.

A CAUTION: 
- I 
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. 
When  the coolant 
in the coolant  recovery  tank is at 
ADD, start your  vehicle. 
If the overheat  warning  continues, there’s one more 
thing  you 
can try. You  can add the proper coolant mix 
directly to  the radiator  but  be sure the cooling system is 
cool before you do it.

How to Add Coolant  to  the  Radiator 
1. You can remove the pressure  cap when  the  cooling 
system, including  the pressure  cap and  upper  radiator 
hose,  is 
no longer hot.  Turn the pressure  cap slowly 
counterclockwise 
until it first stops.  (Don’t press 
down  while  turning  the  pressure cap.) 
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, but now  push 
down  as 
you turn it. Remove  the  pressure  cap.

3. Fill  the  radiator with the proper  coolant  mixture, up 
to  the  base  of the  filler  neck. 4. Then  fill the  coolant  recovery  tank  to

leave  the pressure  cap 
off.

6. Start the engine  and  let it run until you can feel  the 
upper  radiator  hose  getting 
hot. Watch  out for the 
engine  fan. 
7. By this time, the coolant  level inside the filler  neck 
may be  lower. If the  level is lower,  add  nm-e of the 
proper coolant  mixture through the filler neck ~~ntil 
the level reaches  the base of the filler neck. 
8. Then  replace  the  pressure  cap. At any time during 
this  procedure 
if coolant begins to flow  out of the 
filler  neck,  reinstall  the  pressure  cap. Be sure  the 
arrows 
on the  pressure  cap line. up like  this.

If a Tire  Goes  Flat 
It’s Llnusual for a tire  to ”blow  out.’ while you’re  driving, 
especially 
if you  maintain  your tires properly. If air goes 
out of a tire,  it’s  much  more  likely to  leak out slowly. 
But 
if you should  ever have a “blowout,”  here are a few 
tips about  what to  expect  and what  to  do: 
If a front tire fails,  the flat tire will create a drag  that 
pulls the vehicle toward  that side.  Take  your 
f-bot off  the 
accelerator  pedal  and grip the steering  wheel 
firmly. 
Steer to maintain  lane  position, and  then gently brake to 
a stop well out of  the  traffic  lane. 
A rear  blowout.  particularly on a curve, acts much like a 
skid and may  require  the same  conxxtion  you’d use in a 
skid. In any rear  blowout,  remove your foot from the 
accelerator pedal.  Get  the vehicle  under control  by 
steering  the  way 
you want  the  vehicle to go. It may  be 
very  bumpy  and noisy,  but 
YOLI can still  steer. Gently 
brake  to 
a stop -- well off the  road  if possible. 
If a tire  goes  flat,  the  next part shows  how  to  use  your 
jacking  equipment  to change  a flat  tire safely. 
Changing a Flat  Tire 
If a tire goes flat, avoid further  tire  and  wheel damage 
by  driving  slowly  to 
a level place.  Turn  on  your hazard 
warning flashers. 
c 
A CAUTION: 
Changing  a  tire  can  cause  an  injury.  The  vehicle 
can  slip  off the  jack  and  roll over  you 
or other 
people.  You and  they  could  be  badly  injured. 
Find  a  level place  to  change  your  tire. 
To help 
prevent  the  vehicle from  moving: 
1. Set  the  parking  brake  firmly. 
2. Put  the  shift  lever in PARK (P). 
3. Turn off the  engine. 
To be  even  more  certain  the  vehicle  won’t  move, 
you  can  put  blocks  at  the  front  and  rear  of the 
tire  farthest  away  from  the  one  being  changed. 
That  would  be  the  tire  on  the  other  side  of the 
vehicle,  at  the  opposite  end. 
The  following  steps 
will tell  you  how  to  use  the  jack and 
change 
a tire.

Removing  the  Spare  Tire  and  Tools 
The  jacking equipment you’ll  need is stored along the 
driver’s rear wall.  Your vehicle 
is also equipped  with 
work gloves 
and a plastic ground  mat  to assist in the 
changing 
of a flat tire. 
To remove  the jack 
cover,  pull 
up on  the 
latch 
at the end of the 
cover, near  the endgate. 
Then pull  up 
on the latch  on the top of the  cover. 
Remove  the  wheel  blocks, jack and wheel  wrench. 
The spare tire 
is stored under the vehicle. 
I NOTICE: 
Never  remove or  restow  a tire frodto  a stowage 
position under  the vehicle while the  vehicle 
is 
supported by a jack.  Always  tighten the  tire fully 
against the underside of the vehicle  when 
restowing.

Turn the wheel wrench  counterclockwise  to  lower the 
spare  tire.  Keep turning  the  wheel wrench 
until the spare 
tire can  be pulled  out from  under  the vehicle. 
When the tire  has  been completely  lowered, 
tilt the 
retainer  at  the end 
of the cable  and pull it through  the 
wheel  opening.  Pull  the tire out  from  under the vehicle. 
I NOTICE: 
To help  avoid vehicle damage,  do not  drive  the 
vehicle before the  cable is restored. 
A 
Put  the spare  tire near the flat tire. 
The tools you'll  be using include the  jack (A), the wheel 
wrench 
(B) and  the hub  cap removal tool (C). 
You will  have to take off the hub  cap  to reach  your 
wheel nuts.

Page 210 of 358
Position the hub  cap  removal  tool in the notch and pull 
straight away from the wheel  to avoid potential  damage 
to  the  hub  cap  and wheel  surface.  Remove the  hub cap. 
Removing  the  Flat  Tire and Installing  the 
Spare  Tire 
1.  Using the wheel wrench, loosen all the wheel nuts. 
Don’t remove them yet. 
2. Turn the  jack  handle clockwise  to raise the  jack 
lift head. 
3. Fit the  jack into the appropriate hole nearest the 
flat  tire.
