torque OLDSMOBILE BRAVADA 1994 Owners Manual

Torque Lock
If you are parking on a hill and you
don’t shift your transmission into
P
(Park) properly, the weight of the
vehicle may put too much force on the
parking pawl in the transmission. You
may find it difficult
to pull the shift
lever out of
P (Park). This is called
“torque lock.”
To prevent torque lock,
set the parking brake and then shift into
P (Park) properly before you leave the
driver’s seat.
To find out how, see
Shifting Into P (Park) in the Index.
When you are ready to drive, move the
shift lever out of
P (Park) BEFORE you
release the parking brake.
If “torque lock” does occur, you may
need to have another vehicle push yours
a little uphill to take some
of the
pressure from the transmission,
so you
can pull the
shift lever out of P (Park).

all conditions-both on and off paved
surfaces, no matter
if the weather is fair
or foul.
The heart of the AWD system is the
transfer case. Here, engine power is
divided by an interaxle differential.
Under normal conditions,
it sends 65
percent of the torque to the rear axle and
the other 35 percent to the front axle.
But on a slippery surface, a viscous
clutch in the transfer case adjusts the
65/35 proportion according to need,
sending more power to the axle with
traction.
Another feature of the AWD system
that helps Bravada keep its grip is the
limited-slip rear axle. In conditions
where one rear wheel
loses traction but
the other still has some-as when one
wheel hits an icy patch or slips onto a
muddy road shoulder-this design
provides power to the wheel with
traction. And AWD is simple. It’s
always there-working.
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 foot
and do it. That’s
reaction time.
Average reaction time is about 3/4 of a
second. But that’s only an average. It
might be less with one driver and as
long as two or three seconds or more
with another. Age, physical condition,
alertness, coordination, and eyesight all
play a part.
So do alcohol, drugs and
frustration. But even in
3/4 of a second,
a vehicle moving at 60 mph
(100 km/h)
travels 66 feet
(20 m). That could be a
lot
of distance in an emergency, so
keeping enough space between your
vehicle and others is important.
And, of course, actual stopping
distances vary greatly with the surface
of the road (whether it’s pavement or
gravel); the condition of the road (wet,
dry, icy); tire tread; and the condition of
your brakes. 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.

16. Replace the wheel nut cover on the
spare wheel. Be sure to insert the
pin on the wheel cover into the hole
in the wheel. Screw the cover in
place using the TorxB head wrench.
17. Lower the jack head completely by
rotating the jack handle
counterclockwise. If you have an
inside-mounted spare tire, return
the jack and wheel wrench to their
storage compartment and secure
them with the wing nut. Replace the
jack storage compartment cover.
18. Fasten the flat tire where the spare
was stored. If you have a tailgate-
mounted spare tire carrier, tighten
firmly. Push and pull to make sure it
is not loose.
As soon as possible,
tighten the nuts to 22-32 pound-feet
(30-40
Nom) torque.
I If You’re Stuck: In Sand,
Mud, Ice or Snow
19. If you have a tailgate-mounted spare
tire, return the jack and wheel
wrench to their storage
compartment and replace the jack
storage compartment cover. Insert
the cover tabs into the trim panel,
align the cover and fasten the latch. What
you
don’t want to do when your
vehicle is stuck is to spin your wheels.
The method known as “rocking” can
help you get out when you’re stuck, but
you must use caution.
