“95 OIL LIFE INDEX,” for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The
“OIL LIFE INDEX’ may say to change the oil sooner than your
maintenance schedule. This can happen
if driving conditions, such as
short trips in cold weather, cause shorter oil life. Always keep a written
record
of the mileage and date when you last changed your oil. For more
information on
when to change your oil, see the “Maintenance
Schedule.”
If you see “CHANGE OIL
SOON,” it means that you have less than 10%
of your oil life left, and you should consider changing your engine oi\
l.
If you see
“CHANGE ENGINE OIL,” it means the oil life is gone and
you should change the oil right away (certainly within
200 more miles
[320 km]).
The system probably will say to change the oil between 3000 miles (5000
km) and 7500 miles (12500 km), but it may even say to change it before
3000 under very severe conditions. It all depends on your driving
patterns. If it’s been
7500 miles (12500 km) it will say to change oil.
There are
two things the system doesn’t do:
It can’t sense heavy dust in the places where you drive. If you drive in
a dusty area, you should change your oil every 3000 miles (5000 km)
or
3 months (whichever comes first), unless the display says to change
it even sooner than that.
It doesn’t check how much oil you have, so you’ll still have to check
Also, for the system to work right, it is important that you use SG oil, as
discussed earlier. for that.
To see how,
see Index under “Engine Oil.”
when You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do it, display
the “OIL LIFE INDEX’ by pressing the “Information” button. Then
press and hold the “STORE/RECALC’ buttons
until the display shows
“100.”

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:
0
0

a
“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 traffic.
If you suspect that the driver of the vehicle you want
to pass isn’t
aware
of your presence, tap the horn a couple of times before passing.
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.
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.
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

If the vehicle approaching you has its high beams on, signal by flicking
yours to high and

A Few More Night Driving Suggestions
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. Tobacco smoke also
makes inside glass surfaces
very filmy and can be a vision hazard if it's left
there.
Dirty glass makes lights dazzle and flash more than clean glass would,
making the pupils
of your eyes contract repeatedly. You might even want
to keep a cloth and some glass cleaner
in your vehicle if you need to clean
your glass frequently.
Remember that your headlights 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 headlights 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,

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.
Here are ways to increase your safety
in city driving:
a

0
Know the best way to get to where you are going. Try not to drive
around trying to pick out a familiar street or landmark. 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 section, “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.

Downloaded from www.Manualslib.com manuals search engine Obey all posted speed limits. But remember that they are for ideal
road, weather and visibility conditions.
You may need to drive below
the posted limit in bad weather or when visibility
is especially poor.
Pull to the right (with care) and stop clear of intersections when you
see or hear emergency vehicles.
FREEWAY DMNG
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.
Entering the Freeway
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. If traffic is light, you may have no problem. But if it is
heavy, find
a gap as you move along the entering lane and time your
approach.
Try to merge into the gap at close to the prevailing speed.
Switch on your turn signal, check your rearview mirrors as you move
