Night Vision 
No one  can  see  as well  at night as in the daytime. But as 
we get older  these differences  increase. A 50-year-old 
driver  may require  at least twice as much  light to  see the 
same  thing  at night as  a  20-year-old. 
What  you do 
in the daytime  can also  affect  your night 
vision.  For  example, 
if you spend the day in bright 
sunshine  you are wise to wear  sunglasses. Your eyes will 
have  less trouble  adjusting  to night. 
But if you’re 
driving,  don’t  wear sunglasses  at night.  They may cut 
down 
on glare  from  headlamps,  but they also make a lot 
of  things  invisible. 
You can  be temporarily  blinded  by approaching 
headlamps. 
It can take  a second or two,  or  even  several 
seconds,  for  your eyes 
to readjust  to the dark.  When  you 
are  faced  with severe  glare  (as  from a driver  who 
doesn’t  lower 
the high beams,  or a vehicle  with 
misaimed  headlamps),  slow down a little.  Avoid  staring 
directly 
into the  approaching  headlamps.  Keep your windshield and 
all the glass on your vehicle 
clean 
-- inside  and out.  Glare  at night is made  much 
worse  by dirt  on the  glass.  Even the  inside  of the glass 
can build  up a  film  caused  by dust.  Dirty  glass makes 
lights  dazzle  and flash  more than clean glass would, 
making the pupils 
of your  eyes  contract  repeatedly. 
Remember that your headlamps  light 
up far  less  of a 
roadway  when  you are 
in a turn or curve.  Keep your 
eyes  moving; that  way,  it’s easier to pick  out dimly 
lighted  objects.  Just  as your headlamps should be 
checked regularly  for  proper  aim, 
so should your eyes 
be  examined  regularly.  Some  drivers suffer from  night 
blindness 
-- the inability  to  see in dim light -- and 
aren’t  even aware  of 
it.

Driving  in  Rain  and on Wet Roads 
Rain and wet roads can mean  driving trouble.  On a wet 
road,  you can’t  stop, accelerate  or turn  as  well  because  your tire-to-road  traction isn’t as 
good 
as on dry roads. 
And, 
if your  tires don’t have  much tread left, you’ll get 
even less traction.  It’s always wise to  go slower  and  be 
cautious 
if rain  starts to  fall  while  you  are driving. The 
surface  may  get  wet  suddenly when your reflexes are 
tuned 
for driving  on dry pavement. 
The  heavier the rain,  the harder 
it is to see. Even if your 
windshield wiper blades  are 
in good shape, a heavy  rain 
can  make 
it harder  to see road signs and traffic signals, 
pavement markings, the edge 
of the road  and even 
people walking. 
It’s  wise  to  keep  your wiping equipment  in good shape 
and  keep  your windshield washer tank filled  with 
washer  fluid. Replace  your windshield wiper inserts 
when  they show signs  of streaking  or missing areas  on 
the windshield,  or when  strips of rubber start to separate 
from  the inserts.

Driving  too  fast through  large water puddles  or even 
going through some  car washes  can  cause  problems,  too. 
The  water may affect  your brakes.  Try to avoid  puddles. 
But  if you  can't,  try to slow  down  before  you hit them. 
A CAUTION: 
,. 
Wet  brakes can cause accidents.  They  won't  work 
as  well  in a quick  stop and may  cause pulling to 
one side.  You could  lose  control 
of the vehicle. 
After driving  through a large puddle  of  water or 
a  car  wash,  apply your brake  pedal lightly  until 
your brakes  work  normally.

Hydroplaning 
Hydroplaning is dangerous. So much  water  can build up 
under your tires  that they can actually ride  on  the  water. 
This  can happen 
if the road  is  wet  enough  and you’re 
going  fast  enough.  When your vehicle  is hydroplaning, 
it  has little  or no contact 
with the road. 
Hydroplaning doesn’t happen  often. 
But it can if your 
tires  do not  have  much  tread or 
if the pressure in one or 
more  is  low.  It  can happen  if 
a lot of water is standing  on 
the road. 
If you  can see reflections from trees, telephone 
poles  or other vehicles,  and raindrops “dimple” the 
water’s surface, there could  be hydroplaning. 
Hydroplaning  usually happens  at higher speeds.  There 
just  isn’t  a hard  and  fast rule  about hydroplaning.  The 
best  advice  is to slow down  when 
it is raining. 
Driving  Through Deep Standing  Water 
NOTICE: 
If you drive too  quickly through deep puddles or 
standing  water,  water  can come in through your 
engine’s air intake and  badly damage your 
engine. Never drive  through  water that is slightly 
lower than  the  underbody 
of your vehicle. If you 
can’t avoid deep puddles or standing  water, drive 
through  them  very  slowly. 
Some  Other  Rainy  Weather Tips 
0 Besides slowing down, allow some  extra following 
distance.  And  be especially careful  when  you pass 
another vehicle.  Allow yourself more clear  room 
ahead,  and 
be prepared to have your  view restricted 
by  road  spray. 
0 Have good tires with proper tread  depth.  (See 
“Tires“ 
in the Index.)

City Driving Here are ways to increase your safety in city  driving: 
0 
0 
One  of the biggest problems  with city  streets is  the 
amount  of traffic on  them. 
You’ll want to watch out  for 
what  the other  drivers  are doing  and  pay  attention to 
traffic  signals. 
e 
Know  the best  way  to get to where  you are 
going.  Get 
a city  map  and plan your trip into an 
unknown part  of the city  just 
as you would for  a 
cross-country  trip. 
Try  to use 
the freeways  that rim  and  crisscross  most 
large cities.  You’ll save time and energy.  (See the 
next part, “Freeway  Driving.”) 
Treat  a green light as 
a warning  signal. A traffic light 
is  there because  the corner  is  busy  enough 
to need it. 
When a light turns green,  and just  before you start to 
move,  check both ways  for vehicles that have  not 
cleared  the intersection  or may  be  running  the 
red  light.

Freeway Driving 
Mile  for mile, freeways (also  called thruways, parkways, 
expressways, turnpikes or superhighways) are the safest 
of all roads. But they have their  own special rules.  The 
most important advice  on freeway driving 
is: Keep 
up  with traffic and  keep  to the right. Drive  at the same 
speed most 
of the other drivers are driving.  Too-fast  or 
too-slow  driving breaks a smooth traffic  flow. Treat  the 
left  lane  on a freeway  as a passing  lane. 
At  the  entrance,  there is usually a ramp that leads 
to the 
freeway.  If  you have a clear view 
of the freeway  as you 
drive along  the entrance ramp,  you should begin 
to 
check  traffic.  Try to determine  where you expect  to 
blend  with the flow. 
Try to merge  into the gap  at close  to 
the  prevailing speed. Switch  on your turn signal,  check 
your mirrors and glance over your shoulder  as often  as 
necessary,  Try to blend smoothly with the traffic flow. 
Once  you are on the freeway,  adjust your speed 
to the 
posted  limit  or  to  the prevailing  rate if it’s  slower. Stay 
in  the right  lane unless  you want  to pass. 
Before changing lanes, check your mirrors.  Then  use 
your turn signal. 
Just  before  you leave the  lane, glance quickly over your 
shoulder 
to make sure there isn’t another vehicle  in your 
“blind” spot.

Once you are moving on the freeway, make  certain you 
allow  a reasonable  following  distance.  Expect to move 
slightly  slower at night. 
When  you  want  to  leave the freeway,  nwve  to the proper 
lane  well 
in advance. If you miss your  exit, do not, 
under any  circumstances,  stop  and back  up. Drive  on to 
the  next  exit. 
The  exit ramp  can be curved,  sometimes  quite sharply. 
The  exit speed  is usually posted. 
Reduce your  speed  according to your speedometer,  not 
to your sense 
of motion. After  driving  for any distance 
at  higher  speeds,  you  may  tend to 
think you are going 
slower than  you actually  are. 
Before  Leaving on a Long  Trip 
Make sure  you're  ready. Try to be well rested. lf you 
must  start when  you're  not fresh 
-- such as  after a day's 
work 
-- don't  plan to make  too many  miles that first  part 
of the journey.  Wear comfortable  clothing  and shoes  you 
can easily drive 
in. 
Is your vehicle  ready for a long trip'! If you keep it 
serviced and maintained,  it's  ready to go. If it needs 
service,  have 
it done before starting out. Of course, 
you'll  find experienced  and able  service  experts 
in 
Oldsmobile  retailers  all across  North America.  They'll 
be  ready  and 
willing to help if you  need  it.

Highway  Hypnosis 
Is there  actually  such a condition as “highway  hypnosis”‘? 
Or  is 
it just  plain  falling  asleep  at  the  wheel?  Call it 
highway  hypnosis,  lack  of awareness,  or whatever. 
There  is something about  an easy stretch  of road  with 
the same scenery, along  with the 
hum of  the  tires on the 
road,  the drone 
of the engine,  and the  rush of the wind 
against the vehicle  that can make  you  sleepy.  Don’t let it 
happen  to you! 
If it does, your vehicle can leave  the 
road 
in less than a second, and  you  could crash and 
be  injured. 
What  can  you do about highway hypnosis?  Erst, be 
aware  that 
it can happen. 
Then here are some tips: 
0 Make sure your vehicle is well ventilated,  with a 
comfortably cool interior. 
0 Keep  your  eyes moving.  Scan the  road  ahead and 
to  the  sides. Check  your mirrors  and your 
instruments frequently. 
If you  get sleepy,  pull off the  road into  a rest, service 
or parking area  and take  a nap, get some  exercise, or 
both. For safety, treat  drowsiness on the  highway 
as 
an emergency. 
Hill and  Mountain  Roads 
Driving on steep hills  or mountains  is different from 
driving 
in flat  or rolling terrain. 
4-36 
ProCarManuals.com 
Page 169 of 358
If you drive  regularly in steep country,  or if you’re 
planning 
to visit  there,  here are  some tips that can  make 
your trips safer and  more  enjoyable. (See “Off-Road 
Driving” 
in the  Index  for information  about  driving 
off-road.) 
Keep your vehicle in good  shape.  Check all  fl~lid 
levels and also  the brakes,  tires.  cooling system and 
transmission.  These  parts can work hard on 
mountain roads. 
Know  how  to go down hills.  The most  important 
thing to know  is this:  let  your  engine do some 
of the 
slowing  down. Shift to  a lower  gear 
when you go 
down  a  steep  or long hill. 
A CAUTION: 
If you  don’t  shift  down,  your  brakes  could  get 
so hot  that  they  wouldn’t  work  well. You would 
then  have  poor  braking  or  even  none  going 
down 
a hill.  You  could  crash.  Shift  down  to  let 
your  engine  assist  your  brakes  on 
a steep 
downhill  slope.  Coasting 
downhill in  NEUTRAL 
(N) or with  the 
ignition 
off is dangerous.  Your brakes  will have to 
do all  the  work of slowing  down. They could  get so 
hot that  they  wouldn’t  work well.  You  would then 
have  poor  braking  or even  none  going down 
a hill. 
You  could  crash. 
Always have  your  engine running 
and  your  vehicle  in gear  when  you  go  downhill. 
Know how  to go uphill.  You  may  want  to  shift  down  to  a 
lower  gear.  The  lower  gears  help  cool  your  engine  and 
transmission,  and  you  can climb the 
hill better. 
Stay in your own  lane  when driving on two-lane 
roads 
in hills or  mountains.  Don*t swing wide  or  cut 
across  the center  of the road. Drive  at speeds that  let 
you  stay 
in your  own lane. 
As you go over the  top of a hill, be alert.  There  could  be 
something 
in your  lane,  like  a stalled car or  an  accident. 
You  may  see  highway  signs on mountains  that  warn of 
special  problems.  Examples  are  long  grades,  passing or 
no-passing  zones, a falling rocks area or winding 
roads.  Be  alert  to  these  and  take  appropriate  action.

Winter  Driving 
Here are some tips for winter driving: 
0 Have your Oldsmobile in good shape for  winter. 
0 You may  want  to put  winter emergency supplies in 
your vehicle.  Include 
an  ice scraper,  a small brush  or broom, 
a supply 
of  windshield washer  fluid,  a rag, 
some winter outer 
clothing,  a small  shovel,  a  flashlight, 
a red cloth  and 
reflective warning triangles.  And, 
if you  will  be driving 
under  severe  conditions, include 
a small bag of sand, a 
piece of old carpet  or a couple of burlap  bags to help 
provide traction.  Be sure  you properly  secure these 
items 
in your  vehicle. 
Driving on Snow  or Ice 
Most of  the  time, those places where  your tires meet  the 
road  probably  have good traction. 
However, 
if there is snow  or ice  between  your tires and 
the  road,  you can have 
a very  slippery situation.  You’ll 
have 
a lot  less  traction or “grip” and will need  to  be 
very  careful.
