introduced  the 
which  set  the  trend  in  automotive 
styling  for  nearly  two  decades. This 
was  followed 
by the 1949 model  with 
the  two  door  hardtop  Coupe DeVille 
and  the  modern  overhead  valve, 
high  compression 
V8 engine. 
Engineering  innovations,  con- 
veniences  and styling  dominated  the 
'50s and '60s. Cruise  control,  auto- 
matic  climate  control, 
tilt and 
telescoping  steering  wheels,  twilight 
sentinel  and four door  hard  tops  all 
debuted  in  these years.  In 
1957 the 
Eldorado  Brougham  featured  ad- 
vances  such as  air suspension,  mem- 
ory  seat,  automatic  electric  door

5. Take  your foot off the accelerator  pedal. 
To Resume a Set Speed 
Suppose  you set your  Cruise  Control at a desired speed. and then  you 
apply  the brake.  This, 
of course, shuts off the  Cruise.Contro1.  But  you 
don’t  need to reset  it.  Once  you’re  going  about 
25 mph .(40 km/h) or 
more, you can. move  the Cruise Control  switch  from “ON” to “WA” 
(-Resume/Accelerate)  for  about half a  second. 
r 
r 
You’ll  go right  back  up  to your  chosen  speed and  stay  there.

To Increase-Speed While Using Cruise  Control 
,- There  are two waysto go,to a higher  speed.  Here’s  the first: 
0 ’ Use  .the accelerator pedal  to get  to the  higher  speed. 
r 
0 Push  the  button  at  the  .end of the  lever,  then release the button  and 
Here’s  the second  way’to goto 
a higher speed: 
.the 
accelerator  pedal. You’ll  now  cruise at  the higher  speed. 
r Move the Cruise  switch  from “ON’ to “R/A.’’. Hold  it  there until you 
i get up  to  the  speed you want,  and thenrelease  the  switch.

r 
‘0 To increase your,speed  in very small  amounts,  move the switch  to ‘WA.” 
Each time  you do this, your  vehicle  will go about 1 mph (1.6 km/h) faster. 
r   

Downloaded from www.Manualslib.com manuals search engine The accelerate feature will  only  work  after you  have  set  the Cruise 
Control  speed by pushing  the 
“SET CRUISE” button. 
To Reduce  Speed  While  Using  Cruise  Control 
There  are two ways to reduce  your  speed  while  using  cruise  control: 
Push  in  the button  at  the end of the  lever until you  reach  the  lower 
speed  you  want,  then  release  it. 
To  slow  down in very  small  amounts,  push  the  button  for  less  than  half 
a  second.  Each  time  you 
do this,  you’ll go 1 mph (1.6 kmk) slower. 
Passing  Another  khicle While  Using  Cruise  Control 
Use the accelerator  pedal to increase  your  speed.  When  you take  your 
foot  off the  pedal,  your  vehicle 
will slow  down  to the  Cruise  Control 
speed  you set earlier. 
Using  Cruise Control on Hills 
How well  your  Cruise  Control will work  on  hills  depends  upon  your 
speed,  load,  and  the steepness 
of the hills.  When  going  up  steep hills,  you 
may  have 
to step  on the  accelerator  pedal  to maintain  your  speed.  When 
going  downhill,  you  may  have  to brake  or shift 
to a lower  gear  to keep 
your  speed  down.  Of course,  applying  the brake  takes  you out 
of Cruise 
Control.  Many  drivers 
find this to be  too  much  trouble  and  don’t  use 
Cruise  Control  on steep  hills.

Your  vehicle  has traction control system that limits  wheel  spin.  This  is 
especially  useful  in  slippery  road conditions.  The system  operates  only 
if 
it senses that  one  or  both of the  front  wheels are spinning  or- beginning  to 
lose  traction.  When .this happens,  the system  works  the  front brakes and 
reduces  engine  power  (by  shutting 
off fuel injectors) to limit  wheel  spin. 
The  “TRACTION  ACTIVE”  message  will  display on  the Driver 
Information  Center when the traction control  system  is  limiting  wheel 
spin.  See “Driver  Information  Center Messages”  in  the Index.  You  may 
feel  the system  working,  or you  may  notice  some  noise,  but this 
is nomal. 
If your  vehicle  is  in  cruise  control when the traction control  system  begins 
to  limit  wheel  spin,  the cruise  control  will automatically  disengage.  When 
road  conditions  allow  you  to safely  use  it again,  you  may 
turn the  cruise 
control  back  on.  (See “Cruise Control”  in the  Index.) 
The  “TRACTION  DISABLED”  message 
will display  on  the Driver 
Information  Center 
if there’s  a  problem  with  your  traction control system. 
See  “D,river  Information  Center Messages”  in  the Index.  When.  this 
message  is  displayed,  the system  will  not limit  wheel  spin.  Adjust  your 
driving  accordingly. 
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.
