’ C-ontrol of. a Vehicle 
You have  three  systems  ‘that  make  your  vehicle  go  where 
you  want  it to  go.  They  are  the  brakes,  the  ,steering  and 
, 
, .= the  &ccelerator. All three  systems  have‘to do their  ‘work

Braking 
Braking  action  involves perception time and 
reaction  time. 
First, you- have  to  decide  to  push on .the brake  pedal. 
That’s 
perception time. Then  you, have to  bring up your 
€oot  and  do  it. 
Thah reaction  time. 
Average reacbioPz time is-about 3/4 of a  second.  But

~  ~~~~ 
~  ~~~  ~ Avoid  needless  heavy  braking. 
Some people  drive 
in  spurts 
-- heavy  acceleration  followed  by  heavy 
braking 
-- rather  than  keeping  pace  with  traffic.  This  is  a 
mistake.  Your brakes  may  not  have  time  to  cool  between 
hard  stops.  Your  brakes  will  wear  out  much  faster  if  you 
do  a  lot  of  heavy  braking.  If  you keep  pace  with  the 
traffic  and  allow  realistic  following  distances,  you  will 
eliminate  a  lot 
of unnecessary  braking.  That  means 
better  braking  and  longer  brake  life. 
If  your  engine  ever  stops while  you’re  driving,  brake 
normally  but  don’t  pump  your  brakes.  If  you do, the 
pedal  may  get  harder  to push  down. 
If your  engine 
stops,  you  will  still  have  some  power  brake  assist.  But 
you  will  use  it  when  you  brake.  Once  the  power  assist  is 
used  up,  it may  take  longer  to stop  and  the  brake  pedal 
will  be  harder  to  push.

Anti-Lock Brakes 
Your 
vehicle  has  anti-lock  brakes  (ABS).  ABS  is  an 
advanced  electronic  braking  system  that  will  help 
prevent  a  braking  skid. 
When  you  start  your  engine,  or  when  you  begin  to  drive away,  your  anti-lock  brake  system  will  check  itself.  You 
may  hear  a  momentary  motor  or clicking  noise  while 
this  test is going  on,  and  you  may  even  notice  that  your 
brake  pedal  moves  a  little.  This  is  normal. 
If there’s  a  problem  with  the 
anti-lock  brake  system,  this 
warning  light will  stay  on  or 
flash.  See “Anti-Lock 
Brake  System  Warning 
Light”  in  the  Index.

Remember:  Anti-lock  doesn’t  change  the  time  you  need 
to  get  your  foot  up  to  the  brake  pedal  or  always  decrease stopping  distance.  If  you get  too  close  to  the  vehicle  in 
front  of  you,  you  won’t  have time  to  apply  your  brakes 
if  that  vehicle  suddenly  slows  or stops.  Always  leave 
enough  room  up  ahead  to  stop,  even  though  you  have 
anti-lock  brakes. 
Using Anti-Lock 
Don’t  pump  the  brakes.  Just  hold the brake  pedal 
down  and  let anti-lock  work  for you. 
You may  feel the 
1 system  working,  or you  may  notice  some  noise,  but  this 
~ is normal. 
LOW

When  your  anti-lock  system 
is  adjusting  brake  pressure 
to  help  avoid  a  braking  skid, 
this  light  will  come on. 
See

Active  Light”  in  the  Index. 
Braking in  Emergencies 
Use  your  anti-lock  braking  system  when  you  need  to. 
With  anti-lock,  you  can  steer  and  brake  at the  same 
time.  In  many  emergencies,  steering  can  help you  more 
than  even 
the very  best  braking. 
Steering 
Power  Steering 
If  you  lose power  steering  assist  because  the  engine 
stops  dr the  system  is  not  functioning,  you  can steer  but 
it  will  take  much  more  effort. 
Variable  Assist  Steering (Option) 
This steering  system  provides  lighter  steering  effort for 
parking  and  when  driving  at  low  speeds.  Steering  effort 
will  increase  at  higher’speeds for  improved  road  feel. 
Steering  Tips 
Driving  on Curves 
It’s  important  to  take  curves  at a  reasonable  speed. 
A lot  of  the  “driver  lost  control”  accidents  mentioned  on 
the  news  happen  on  curves.  Here’s  why:  
     
        
        Page 157 of 356

Experienced driver or beginner, each of  us  is subject to 
the  same  laws of physics  when  driving on curves.  The 
traction  of the tires against  the road  surface  makes it 
possible  for the vehicle to  change  its path  when  you  turn 
the  front  wheels.  If there’s  no  traction, inertia will  keep 
the vehicle  going  in the same direction.  If you’ve  ever 
tried to steer a vehicle  on  wet ice, you’ll understand  this. 
The  traction  you  can  get 
in a  curve  depends  on  the 
condition 
of your  tires  and  the  road  surface,  the  angle  at 
which 
the curve  is banked,  and your speed. While  you’re 
in  a curve,  speed  is the  one  factor  you  can  control. 
Suppose  you’re  steering  through  a sharp  curve.  Then  you 
suddenly  accelerate.  Both  control  systems 
-- steering  and 
acceleration 
-- have  to  do  their  work  where  the  tires  meet 
the  road.  Adding  the  sudden  acceleration  can  demand  too 
much  of  those  places.  You  can  lose  control. 
What  should  you  do if this ever happens? Ease  up  on  the 
accelerator pedal, steer the vehicle the  way 
you want it 
to go,  and  slow  down. 
Speed limit signs  near curves  warn  that  you  should 
adjust  your  speed.  Of course,  the posted  speeds  are 
based  on  good  weather  and  road  conditions. Under less 
favorable conditions you’ll  want 
to go  slower. 
If you  need  to reduce your  speed as you  approach  a 
curve,  do it before  you enter  the curve,  while  your  front 
wheels  are straight ahead. 
Try to adjust  your  speed so you can “drive” through  the 
curve.  Maintain  a reasonable,  steady  speed.  Wait  to 
accelerate until  you are out  of the curve,  and  then 
accelerate  gently into the straightaway. 
Steering in Emergencies 
There are times  when  steering  can  be  more  effective  than 
braking.  For  example,  you  come  over  a hill  and  find  a 
truck  stopped  in  your  lane,  or  a car  suddenly  pulls  out 
from nowhere,  or  a child darts out  from  between  parked 
cars  and  stops  right 
in front  of  you.  You  can  avoid  these 
problems  by  braking 
-- if you  can  stop  in  time.  But 
sometimes  you  can’t;  there  isn’t  room.  That’s  the  time \
 for 
evasive  action 
-- steering  around  the  problem. 
Your  Oldsmobile  can perform  very  well in  emergencies 
like these. First  apply  your brakes. (See  “Braking  in 
Emergencies”  earlierin this section.)  It  is better  to 
remove  as  much  speed  as  you  can from a  possible 
collision. Then  ste.er around  the problem,  to the left  or 
right depending  on  the space available.

Passing 
The driver  of  a  vehicle  about  to pass  another  on  a 
two-lane  highway  waits  for just  the  right  moment, 
accelerates,  moves  around  the  vehicle  ahead,  then  goes 
back  into the  right  lane again.  A  simple  maneuver? 
Not  necessarily!  Passing  another  vehicle  on a  two-lane 
highway  is a  potentially  dangerous  move,  since  the 
passing  vehicle  occupies  the same lane as  oncoming 
traffic  for several  seconds.  A  miscalculation,  an error  in 
judgment, or  a  brief  surrender  to  frustration  or anger  can 
suddenly  put the passing  driver  face to face  with the 
worst  of  all  traffic  accidents 
-- the  head-on  collision. 
So here  are some  tips for passing: 
“Drive  ahead.”  Look  down the road, to the  sides  and  to 
crossroads  for  situations  that  might  affect 
your passing 
patterns. 
If you  have  any  doubt  whatsoever  about 
making  a  successful  pass,  wait  for  a  better  time. 
Watch  for  traffic  signs,  pavement  markings  and  lines. 
If you  can  see  a  sign  up  ahead  that  might  indicate  a 
turn or an intersection,  delay  your  pass.  A  broken 
center  line  usually  indicates  it’s 
all right  to pass 
(providing  the  road  ahead  is  clear).  Never  cross  a  solid 
line  on  your  side  of  the  lane  or  a  double  solid  line, 
even 
if the road  seems  empty of approaching traflk. 
Do not  get too  close  to  the  vehicle  you  want  to  pass 
while  you’re  awaiting  an  opportunity.  For one  thing, 
following  too  closely  reduces  your  area  of  vision, 
especially  if you’re  following  a  larger  vehicle. 
Also,  you  won’t  have adequate  space  if  the  vehicle 
ahead  suddenly  slows  or stops.  Keep  back  a 
reasonable  distance. 
0 When  it looks  like a  chance to pass  is coming  up, 
start  to  accelerate  but  stay  in the  right  lane and  don’t 
get  too  close.  Time  your  move 
so you  will  be 
increasing  speed  as  the  time  comes  to  move  into the 
other  lane.  If the  way  is clear  to  pass,  you  will  have a 
“running  start”  that  more than  makes  up  for the 
distance  you  would  lose  by dropping  back.  And 
if 
something  happens  to cause you  to  cancel  your  pass, 
you  need  only  slow  down  and  drop back  again  and 
wait  for another  opportunity. 
If  other  cars  are lined  up  to  pass  a  slow  vehicle,  wait 
your  turn.  But  take  care  that  someone  isn’t  trying  to 
pass  you  as  you  pull  out 
to pass  the  slow  vehicle. 
Remember  to  glance  over  your  shoulder  and  check 
the  blind  spot.

0 Check  your  mirrors,  glance  over  your  shoulder,  and start  your  left  lane  change  signal  before  moving  out 
of the  right  lane  to  pass.  When  you  are  far  enough 
ahead  of  the  passed  vehicle  to  see  its  front  in  your 
inside  mirror,  activate  your  right  lane  change  signal 
and  move  back  into  the  right  lane.  (Remember  that 
your  right  outside  mirror  is convex.  The  vehicle  you 
just  passed  may  seem  to  be  farther  away  from  you 
than  it really  is.) 
0 Try not  to  pass  more  than  one  vehicle  at  a  time  on 
two-lane  roads.  Reconsider  before  passing  the 
next  vehicle. 
0 Don’t  overtake  a  slowly  moving  vehicle  too  rapidly. 
Even  though  the  brake  lamps  are not  flashing,  it may 
be  slowing  down  or starting  to  turn. 
0 If you’re  being  passed,  make  it easy  for  the 
following  driver  to  get  ahead  of you.  Perhaps  you 
can  ease  a  little  to  the  right. 
Loss of Control 
Let’s  review  what  driving  experts  say  about  what 
happens  when  the  three  control  systems  (brakes,  steering 
and  acceleration)  don’t  have  enough  friction  where  the 
tires  meet  the  road  to 
do what  the  driver  has  asked. 
In any  emergency,  don’t  give  up.  Keep  trying  to  steer  and 
constantly 
seek an escape  route  or  area of less  danger. 
Skidding 
In  a  skid,  a  driver  can  lose  control  of  the vehicle. 
Defensive  drivers  avoid  most  skids  by  taking  reasonable 
care suited  to  existing  conditions,  and  by not 
“overdriving”  those  conditions.  But  skids  are 
always  possible. 
The  three  types  of  skids  correspond  to  your 
Oldsmobile’s 
three control  systems.  In  the  braking  skid, 
your  wheels  aren’t  rolling.  In  the  steering  or cornering 
skid,  too  much  speed  or steering  in  a  curve  causes  tires 
to  slip  and  lose  cornering  force.  And  in  the  acceleration 
skid,  too  much  throttle  causes  the  driving  wheels  to spin.
