Torque Lock 
If you  are  parking on a  hill and you  don’t shift your 
transmission  into PARK  (P)  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  PARK (P). This  is called “torque 
lock.”  To  prevent torque  lock,  set  the parking brake and 
then  shift  into PARK 
(P) properly before you  leave 
the  driver’s  seat.  To  find out how, see 
Shifting Into Park 
(P) on page 2-25. 
When  you  are  ready  to drive,  move the  shift  lever  out of 
PARK  (P) 
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  parking pawl in the transmission, 
so 
you  can  pull the shift lever out  of PARK  (P). 
Shifting Out of Park (P) 
Your vehicle  has  an automatic transmission  shift  lock 
control system.  You have to fully  apply  the regular 
brakes  before you  can shift from  PARK  (P) when  the 
ignition  is  in RUN.  See 
Automatic  Transmission 
Operation 
on page 2-22. 
If you  cannot  shift  out of PARK  (P),  ease  pressure  on 
the  shift  lever.  Push the  shift  lever all  the way  into 
PARK  (P) as you  maintain brake application.  Then  press 
the  shift  lever button and  move the  shift  lever  into  the 
gear you  want. 
If you  ever  hold the  brake pedal  down but still  can’t  shift 
out  of PARK (P), try this: 
1. Turn the  key to  LOCK. 
2. Apply  and  hold  the brake until  the  end of Step 4. 
3. Shift  to NEUTRAL (N). 
4. Start the vehicle  and then shift  to  the drive  gear 
you want. 
5. Have the vehicle fixed  as soon  as possible.

Brake Pedal Travel 
The brake  wear  warning  sound  means that 
soon  your  brakes  won’t  work  well.  That could 
lead  to  an accident.  When  you  hear  the  brake 
wear  warning  sound,  have your vehicle 
serviced. 
Notice: Continuing  to drive with  worn-out  brake 
pads  could  result 
in costly  brake repair. 
Some driving conditions  or climates  may cause  a  brake 
squeal  when  the  brakes  are  first  applied or lightly 
applied.  This does  not  mean something  is wrong with 
your  brakes. 
Properly  torqued wheel nuts are  necessary 
to help 
prevent  brake pulsation.  When  tires  are  rotated, inspect 
brake  pads  for  wear  and  evenly tighten  wheel  nuts  in 
the  proper  sequence 
to GM torque  specifications. 
Brake  linings should always be  replaced as  complete 
axle  sets. 
See 
Brake  System  Inspection on  page 6-16. 
See your  dealer if the brake pedal does  not  return  to 
normal height,  or 
if there  is a  rapid increase  in 
pedal travel.  This  could be a sign  of brake trouble. 
Brake  Adjustment 
Every time  you  make a  brake  stop, your  disc  brakes 
adjust  for wear. 
Replacing Brake System Parts 
The  braking system on  a vehicle  is complex. Its many 
parts have 
to be  of top  quality and work  well together if 
the  vehicle  is to have really  good  braking. Your 
vehicle was  designed and tested with  top-quality  GM 
brake parts. When you  replace parts 
of your  braking 
system 
- for  example, when  your brake  linings 
wear  down  and you  need  new ones  put  in 
- be  sure 
you  get new approved  GM  replacement parts. 
If 
you  don’t,  your brakes  may no longer work  properly.  For 
example, 
if someone  puts  in brake linings that  are 
wrong  for your vehicle,  the  balance between your  front 
and  rear  brakes can  change 
- for  the  worse.  The 
braking performance you’ve  come 
to expect  can  change 
in  many other ways 
if someone puts  in the  wrong 
replacement brake parts. 
5-37  

The  purpose of regular rotation is to achieve  more 
uniform  wear  for  all tires  on the vehicle.  The first  rotation 
is the most  important. See  “Part A: Scheduled 
Maintenance Services,” in Section 
6, for  scheduled 
rotation intervals. 
When  rotating  your tires,  always  use  the correct  rotation 
pattern shown  here. 
After  the tires  have been  rotated, adjust the  front and 
rear inflation  pressures as  shown on  the 
Certificationnire  label. Make certain that 
all wheel  nuts 
are  properly tightened.  See “Wheel 
Nut Torque” 
under 
Capacities and  Specifications on page 5-93. 
Rust c. dirt or. - wheel, or  on  the  parts  to 
which 
it is fastened,  can  make  wheel  nuts 
become  loose  after  a  time. 
The wheel  could 
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 
a 
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  the  Index.

12. Use the wheel  wrench 
to tighten the wheel 
nuts firmly  in 
a 
crisscross sequence as 
shown. 
c 
Incorrect  wheel  nuts  or  improperly  tightened 
wheel  nuts  can  cause  the  wheel  to  come  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  new  GM original  equipment  wheel  nuts. 
I 
CAUTION:  (Continued)  Stop  somewhere  as  soon 
as you  can  and  have 
the  nuts  tightened  with  a  torque  wrench  to  the 
proper  torque  specification.  See “Capacities 
and  Specifications” 
in the  Index  for  wheel nut 
torque  specification. 
Notice: Improperly  tightened  wheel nuts can  lead 
to  brake  pulsation  and  rotor  damage. 
To avoid 
expensive  brake  repairs,  evenly  tighten  the  wheel 
nuts  in  the  proper  sequence  and  to  the  proper 
torque  specification.  See “Capacities  and 
Specifications” 
in the  index  for  the  wheel  nut  torque 
specification.
