116 Driving and Operating
Danger (Continued)
have to park on a hill, also turn your
front wheels so the vehicle will roll away
from traffic.
You and others could be seriously injured
or killed.
1. Hold the regular brake pedal down with
your right foot and apply the parking
brake all the way before shifting the
transmission. Follow the Parking Brake
instructions in this manual for your
vehicle.
2. If the vehicle is equipped with a selector
lever with P-range, hold in the button on
the selector lever and push the lever all
the way toward the front of the vehicle
to move the lever to "P" (Park). If the
vehicle is equipped with a selector lever
without P-range, move the selector lever
into N (Neutral).
3. Turn the key to "LOCK".
4. Remove the key and take it with you.
5. Before leaving the driver's seat, be sure
the vehicle is not moving. If the vehicle
is equipped with a selector lever with
P-range, confirm the vehicle is in P
(Park) by pulling the selector lever
toward you without pushing the button.
If you can do this, it means that the
selector lever was not fully locked into
"P" (Park).
Driving Down a Long Slope
When driving down a long slope, use the
exhaust brake together with the foot brakes.
Using the exhaust brake and low-gears
reduces the work load on the foot brakes
and yields greater braking force. Even so,
use the foot brakes appropriately to prevent
the engine over-revving.
Frequent use of the foot brakes can cause
brake fade, resulting in reduced brake
effectiveness.
Brake Fade : Frequent use of the brakes can
cause the brakes to overheat so that the
frictional force of the brake linings decreases
and the brakes become less effective than
normal. This phenomenon is called
brake fade.
Even so, you should be very careful
when using engine braking in a low gear
because the engine is likely to over-rev.
See Exhaust Brake 0 178 and
Selector Lever 0 170.
Do not adjust the exhaust brake valve.
The engine should never be allowed to
exceed the governed speed. Supplement the
exhaust brake with vehicle service brakes
intermittently and/or shift to higher
transmission gear to prevent engine
overspeed. A rule of thumb for gear
selection is that the vehicle should be driven
down a grade in the same gear that would
be used to climb that grade.
Warning
To reduce the risk of personal injury,
before going down a steep or long grade,
reduce speed, turn on the exhaust brake
and shift the transmission to the next
lower gear. This will help control your
speed. Do not hold the brake pedal down
too long or too often while going down a
steep or long grade. This could cause the
brakes to get hot and not to work as
well. As a result, the truck will not slow
down at the usual rate. Failure to take
these steps could result in loss of vehicle
control.
You and others could be seriously injured.
