tion at speeds less than 15 mph (25 km/h), 2nd gear is

When descending a hill, be very careful to downshift
one gear at a time to prevent overspeeding the
engine which can cause valve damage.

Equipped
NOTE: The parking brake should be engaged before
leaving the vehicle, especially on an incline.
Truck models with manual transmission are equipped
with a clutch interlocking ignition system. The clutch
pedal must be fully depressed to start the vehicle.
Fully depress the clutch pedal before shifting gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal. When launching a stationary vehicle, keep the
engine speed low until the clutch is fully engaged.
Damage to the clutch can re-
sult from starting in 2nd or
3rd gear with a loaded ve-
hicle. Use each gear in nu-
merical order – do not skip a
gear.

middle gears (2nd, 3rd and 4th) have ratios that are closer
