OPERATION 143
MOVING THE VEHICLE — GENERAL
INFORMATION
Braking
Avoid sudden stops. Constant sudden stops may negatively affect braking
performance and driving parts. When slowing, leave the clutch (if equipped)
engaged as long as possible to use the braking effect of the engine.
CAUTION
When using the braking effect of the engine, final gear selection is critical. If gear
selection is too high, the vehicle will buck which could cause loss of control.
Engine Temperature
Before entering high-speed traffic conditions, allow the engine to reach normal
operating temperature. A normal operating range is between 77°C and 104°C
(170°F and 220°F) for stationary vehicles.
1. To move the vehicle, begin by starting the engine and waiting until it
reaches normal operating range (see Coolant Temperature Gauge in the
Instrument Panel section for the correct engine temperature).
2. Shift transmission into the desired gear. Refer to the Transmission Shifting
Instructions section for shifting instructions (including the proper starting gear).
3. Release the parking brake.
CAUTION
If the Parking Brake indicator light is on, do NOT attempt to move the vehicle or
driveline damage may result.
4. Apply the accelerator enough for the engine to move the load.
Right-Side Operation
Note:
Speed is restricted to second gear when operating the vehicle from the
right-hand side.
