OD (Automatic  Overdrive).  This  position is for  normal  driving. If you  need 
more  power  for  passing,  and  you’re: 
- Going  less  than  about 35 mph (56 km/h),  push  your  accelerator 
pedal  about  halfway  down. 
- Going  about 35 mph (56 km/h)  or more,  push  the  accelerator  all the 
way  down.  You’ll  shift  down to the  next  gear  and  have  more  power. 
OD should not be  used  when towing  a  trailer,  carrying  a  heavy  load, 
driving  on  steep  hills,  or  for  off-road  driving.  Select 
D (third  gear)  when 
operating  the  vehicle  under  any  of  these  conditions. 
D (Third  Gear).  This is  like OD, but  you  never  go  into  Overdrive.  You 
should  use 
D when  towing  a  trailer,  carrying  a  heavy  load,  driving  on 
steeps  hills,  or  for  off-road  driving. 
2 (Second  Gear).  This  position  gives  you  more  power  but  lower  \
fuel 
economy.  You  can  use 
2 (Second  Gear)  on  hills.  It  can  help  control  your 
speed  as  you  go  down  steep  mountain  roads,  but  then  you  would\
 
also 
want  to use  your  brakes  off  and  on. 
If you  have  a 4.3L engine  (Codes Z and W) and if you  manually  select 
2, the  transmission  will  drive  in second  gear.  You  may  use  this  feature 
for  reducing  torque 
to the  rear  wheels  when  you  are  trying to start  your 
vehicle  from  a  stop  on  slippery  road  surfaces. 
1 (First  Gear).  This  position  gives  you  even  more  power  (but  \
lower  fuel 
economy)  than 
2. You  can  use it on  very  steep  hills,  or in deep  snow or 
mud. If the  selector  lever  is put  in 1, the  transmission  won’t  shift  into 
first  gear  until  the  vehicle  is going  slowly  enough.

To release  the  parking  brake: 
Hold the  regular  brake  pedal  down.  Pull  the  brake  release  lever. 
I NOTICE 
If you  are on a  hill: 
See  “Parking  on  Hills”  in  the  Index.  That  part  shows  how\
  to  turn  your  front 
wheels. 
If you  are  towing  a  trailer  and  are  parking  on  any  hill: 
See  “Towing  a  Trailer” in the  Index.  That  part  shows  what  to 
do first to keep 
the  trailer  from  moving. 
Torque  Lock 
The  parking  brake  should  be set  first  whenever  leaving  the  driver’s  seat. If 
you  are  parked  on  a  hill and  the  transmission  is  placed  in P (Park)  before 
the  parking  brake  is  set, the  weight  of  the vehicle  may  put  too  much  force 
on  the  parking  pawl  in the  transmission. 
It may  be difficult to pull the  selector 
lever  out  of 
P (Park).  This  is called  “torque  lock.”  To prevent  this,  the parking 
brake  should  be  set  BEFORE  moving  the  selector  lever 
to P (Park). 
When  preparing  to  move  the  vehicle,  the  selector  lever  should  \
be  moved  out  of 
P (Park)  BEFORE  releasing  the  parking  brake.  Set  the  parking  br\
ake  first, 
Then  release  the  transmission  from 
P (Park),  even  on  level  surfaces. 
If “torque  lock”  does  occur,  you  may  need to have  another  vehicle  nudge  this 
vehicle  uphill  to  take  some 
of the  pressure off the  transmission  while  you  pull 
the  selector  lever  out  of 
P (Park).

If there  is  no  curb  when  you're  parking  uphill,  turn  the  wheels to the  right. 
If there  is  no  curb  when  you're  parking  uphill  on  the  left  side \
 of  a  one-way 
street,  your  wheels  should  be  turned 
to the  left. 
Torque  Lock  (Automatic  Transmission) 
If you  are  parking  on  a  hill  and  you  don't  shift  your  transmissi\
on  into P 
(Park)  properly,  the  weight  of  the  vehicle  may  put  too  much \
 force  on  the 
parking  pawl  in  the  transmission. 
You may  find it difficult  to  pull  the  shift  lever 
out  of 
P (Park).  This  is  called  torque  lock.  To prevent  torque  lock,  always  be 
sure  to  shift  into 
P (Park)  before  you  leave  the  driver's  seat. To find  out  how, 
see  "Shifting  Into 
P (Park)  in the  Index." 
When  you  are  ready 
to drive,  move  the  shift  lever  out of P (Park) BEFORE 
you  release  the  parking  brake.

If "torque  lock"  does  occur,  you  may  need to have  another  vehicle  push 
yours  a  little  uphill 
to take  some  of  the  pressure from the  transmission, so 
you  can  pull  the  shift  lever  out of P (Park).

Tighten  the  wheel  nuts  firmly in a  criss-cross  sequence  as  shown.  Remove 
the  wheel  blocks. 
A 
Incorrect  wheel  nuts  or improperly  tightened  wheel  nuts  can  cause 
the  wheel  to become  loose  and  even  come 
off. This  could  lead to 
an  accident.  Be  sure to use  the  correct  wheel  nuts. If you  have  to 
replace  them,  be  sure 
to get  the  right  kind. 
Stop  somewhere  as soon  as  you  can  and  have  the  nuts  tightened 
with 
a torque  wrench  to 95 ft. Ibs. (1 30 N.m ). 
Storing  The  Tire  in  The  Underbody  Carrier 
Put  the  tire  on  the  ground  at  the  rear  of the  vehicle,  with  the  valve  stem 
pointed  down  and  to the  rear. 
Pull  the  retaining  bar  through  the  wheel.  Put the  chisel  end 
of the  wheel 
wrench,  on  an  angle,  through  the  hole  in the  rear  bumper  and  into  the  hoist 
shaft.  Turn  the wheel  wrench  clockwise  until the tire  is  raised  against  the 
underside  of the  vehicle. 
You  will  hear  two  “clicks”  when  the  tire  is secure, 
but pull on  the  tire  to 
make  sure.

Use  this  rotation  pattern. Do not  include  “compact  spare  tire” in rotation, if so 
equipped. 
If your  vehicle  has  front  tires  with  different  load  ratings  or  tr\
ead  designs  (such 
as  all  season  vs.  on/off  road)  than  the  rear  tires,  don’t \
 rotate  your  tires  front 
to  rear. 
If you  have  styled  steel  or  aluminum  wheels,  your  spare  is  full-s\
ized,  but  its 
appearance  will  not  match  your  other  wheels. 
After  the  tires  have  been  rotated,  adjust  the  front  and  rear  \
inflation  pressure  as  shown  on  the  CertificationRire  label.  Make  certain  that 
all wheel  nuts  are 
properly  tightened.  See  “Wheel  Nut  Torque”  in  the  Index. 
A 
Rust  or  dirt  on  a  wheel,  or  on  the  parts  to  which it is fastened,  can 
make  the  wheel  nuts  become  loose  after  a  time.  The  wheel  coul\
d 
come  off  and cause  an  accident.  When  you  change  a wheel,  remove 
any  rust  or  dirt  from  places  where  the  wheel  attaches  to  the \
 vehicle. 
In  an  emergency,  you  can  use  a  cloth  or  paper  towel  to 
do this;  but 
be  sure  to use  a  scraper  or  wire  brush  later,  if  you  need  to,  to  get 
all  the  rust  or  dirt  off.  (See  “Changing  a  Flat  Tire”  in  t\
he  Index.)

Downloaded from www.Manualslib.com manuals search engine Be  sure to use  the  correct  fuse. If you  ever  have  a  problem  on  the  road  and 
don’t  have  a  spare  fuse,  you  can  “borrow”  one  of the  correct  value.  Just  pick 
some  feature  of your  vehicle  that  you  can  get  along  without-like the  radio or 
cigarette  lighter-and  use  its  fuse, 
if it is  of  the  value  you  need.  Replace it 
as  soon  as you  can.  See  “Fuses  and  Circuit  Breakers”  in this  section.
