Torque Lock
Torque lock is when the weight of
the vehicle puts too much force
on the parking pawl in the
transmission. This happens when
parking on a hill and shifting
the transmission into P (Park) is
not done properly and then it
is difficult to shift out of P (Park).
To prevent torque lock, set the
parking brake and then shift into
P (Park). To nd out how, see
“Shifting Into Park” listed previously.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so
you can shift out of P (Park).
Shifting Out of Park
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal
unless the shift lever is in P (Park)
with the shift lever button fully
released, and
Prevent movement of the shift
lever out of P (Park), unless
the ignition is in ON/RUN or
ACC/ACCESSORY and the
regular brake pedal is applied.
The shift lock release is always
functional except in the case of
an uncharged or low voltage
(less than 9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. SeeJump Starting on
page 5-28for more information.To shift out of P (Park) use the
following:
1. Apply the brake pedal.
2. Press the shift lever button.
3. Move the shift lever to the
desired position.
If you still are unable to shift out
of P (Park):
1. Fully release the shift lever
button.
2. While holding down the brake
pedal, press the shift lever
button again.
3. Move the shift lever to the
desired position.
If you still cannot move the shift
lever from P (Park), consult
your dealer/retailer.

And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry, or
icy; tire tread; the condition of
the brakes; the weight of the vehicle;
and the amount of brake force
applied.
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. The brakes might
not have time to cool between
hard stops. The brakes will wear out
much faster with a lot of heavy
braking. Keeping pace with
the traffic and allowing realistic
following distances eliminates a lot
of unnecessary braking. That
means better braking and longer
brake life.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,the pedal could get harder to push
down. If the engine stops, there
will still be some power brake assist
but it will be used when the brake
is applied. Once the power assist is
used up, it can take longer to
stop and the brake pedal will be
harder to push.
Adding non-dealer/non-retailer
accessories can affect vehicle’
performance. SeeAccessories and
Modifications on page 5-3.
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that will
help prevent a braking skid.
When the engine is started and the
vehicle begins to drive away,
ABS checks itself. A momentary
motor or clicking noise might
be heard while this test is going on,
and it might even be noticed that
the brake pedal moves a little. This
is normal.If there is a problem with ABS, this
warning light stays on. See
Antilock Brake System (ABS)
Warning Light on page 3-34.
Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you. You
slam on the brakes and continue
braking. Here is what happens
with ABS:
A computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work
the brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the
obstacle while braking hard.
