turn signal BUICK TERRAZA 2007 Owner's Guide

Driving in Rain and on Wet RoadsRain and wet roads can mean driving trouble. On
a wet road, you cannot stop, accelerate, or
turn as well because your tire-to-road traction is
not as good as on dry roads. And, if your tires do
not have much tread left, you will get even less
traction. It is 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 reexes 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.

City Driving
One of the biggest problems with city streets is
the amount of traffic on them. You will 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:
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 will save time and
energy. SeeFreeway Driving on page 369.
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
ow. 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 ow. 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 ow.
Once you are on the freeway, adjust your speed
to the posted limit or to the prevailing rate if it
is 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 is not
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.

Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could be
damaged. Avoid making very sharp turns
while trailering.
When you are turning with a trailer, make wider
turns than normal. Do this so your trailer will
not strike soft shoulders, curbs, road signs, trees,
or other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring.
The arrows on your instrument panel will ash
whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also
ash, telling other drivers you are about to turn,
change lanes, or stop.When towing a trailer, the arrows on your
instrument panel will ash for turns even if the
bulbs on the trailer are burned out. Thus, you may
think drivers behind you are seeing your signal
when they are not. It is important to check
occasionally to be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower gear before
you start down a long or steep downgrade. If you
do not shift down, you might have to use your
brakes so much that they would get hot and
no longer work well.
If you are towing a trailer that weighs more than
1,000 lbs (450 kg), you may prefer to drive in
THIRD (3) instead of DRIVE (D) or, as you need
to, a lower gear. This will minimize heat build-up
and extend the life of your transaxle.
