Seat and steering wheel adjustments 3 Seat belt safety Children and infants • When carrying children or infants, restrain them properly. This will minimize the risk of injury in the event of a sudden stop or accident. Never allow children to stand or kneel on the seats. For maximum safety, we recommend fitting and using a restraint system that complies with Fed- eral Motor Vehicle Safety Standards.
Steering wheel WARNING • After every adjustment, try to move the steering wheel back and forth to make sure that it is securely locked. Unless the adjusting lever returns to its original locked position, the steering wheel may move while the vehicle is in motion. This could cause an accident.
Ignition switch WARNING Never turn the ignition switch to any position other than “ON” while driving the vehicle. Turning the ignition switch to the “ACC” position would create the following prob- lems: • The engine would shut down. • Braking force would be greatly reduced. •...

5-11 NOTE: Idling the engine for a long time wastes fuel. It wastes natural resources and causes air pollution. Shut down the engine whenever you leave the vehi- cle, even for a short period. If the engine has been idling for a relatively long time, the muffler may give off white smoke during acceleration.
5-12 Switches and controls Shutting down the engine WARNING • Never allow the vehicle to coast with the engine shut down. This could cause dam- age to the fuel injection system, diminish braking efficiency, and make steering extremely difficult. This could cause an injury accident or loss of life.
Page 46
If the warning light illuminates while the vehicle is being driven, the disc brake pads may need replacement. Have the disc brake pads inspected at an authorized Sterling service facil- ity. • As a bulb check, the warning light illumi- nates when the ignition switch is turned on and goes off approximately three seconds later.

5-21 Full exhaust brake function will return as soon as the original conditions have been restored. Wiper/ washer switch WARNING In cold weather, use the heater to warm the windshield before operating the washers. Washer fluid could freeze on the windshield, obstruct your vision, and cause an accident.
5-22 Switches and controls Hazard flashers CAUTION If the hazard flashers are operated for an extended period of time, this can discharge the battery and make the engine impossible to start. The hazard flashers are used to warn other traffic if you find it necessary to stop your vehicle in an emergency.

If the light stays off, there is no problem. If the light illuminates again, bring the vehicle to an authorized Sterling service facility as soon as possible. Check engine warning (red) The red check engine warning illuminates when there is a serious malfunction in the electronic con- trol circuitry of the fuel injection system.
If the fault does not clear, or the light soon comes back on, have the vehicle checked by an authorized Sterling service facility. Even with a fault in the electronic control system, the vehicle can still be driven in a “derate” mode.
Starting and driving Vehicle start-up • Do not carry containers of fuel or spray cans in the cab. WARNING Z11316 Do not carry fuel in the cab. An increase in cab temperature could cause the fuel vapor to catch fire, with risk of personal injury or loss of life.
P. 6-5 • If you are unable to identify the cause of the problem, contact an authorized Sterling service facility. • Be especially careful during high-speed driving. Avoid sharp turns and hard braking except in emergencies.
Page 72
Starting and driving • While driving, keep your eyes moving. Keep a clear view ahead, behind, and to both sides of the vehicle. • Do not keep the steering wheel turned all the way to either side for more than 10 seconds. This could cause the power steering system to malfunction.
Page 73
• Do not release the clutch pedal suddenly. This places undue stress on the vehicle and shortens the service life of the clutch. • Do not operate the vehicle with the clutch disen- gaged or the gearshift lever in neutral. This makes the exhaust brake ineffective.
Starting and driving Improving fuel economy Observe the following precautions to achieve maxi- mum fuel economy and to extend tire life. • When the needle on the coolant temperature gauge begins to move upward, the engine is warm enough. Further warming wastes fuel. •...
Braking On downhill grades, use the engine brake and the exhaust brake to slow the vehicle, before using the service brakes to stop the vehicle. Do not rely exclusively on the service brakes. P. 7-9 Z01416 WARNING • If any of the brake warning lights illumi- nate, there is a possibility of brake failure.
Page 76
Starting and driving NOTE: On slippery surfaces, the wheels could lock when the brakes are applied. This could cause a skid. ABS controls the braking force applied to each wheel in order to minimize skids. • If the warning light illuminates during driv- ing, it indicates an ABS fault.
• Before you install radio transmitter/receiver equipment or tires of a size different from the original ones, be sure to consult an authorized Sterling service facility. • Even if the ABS system fails and the warn- ing light illuminates, the service brakes can still stop the vehicle, although brake performance may be reduced under certain conditions.
Page 78
7-10 Starting and driving • Never coast downhill with the shift lever in neu- tral <manual transmission vehicles> or the shift selector in “N” (neutral) <automatic transmission vehicles>. This eliminates the effect of both the engine brake and the exhaust brake. This causes the service brakes to overheat and the brake linings to wear prematurely.
If water has entered the high-amp fuse box, remove the water and have the vehicle inspected by an authorized Sterling service facil- ity. Water in the high-amp fuse box could cause a short circuit that results in a fire.
7-12 Starting and driving Parking WARNING • Park the vehicle on a level surface, if avail- ble. Avoid parking on slopes. The vehicle could roll and cause an injury accident. • engine exhaust pipe extremely hot immediately after the vehi- cle has been driven.
Page 81
7-13 WARNING Brake faults that would cause the warn- ing light to illuminate have no effect on the parking brake. If the warning light illumi- nates, the parking brake will stop the vehicle if necessary and prevent an injury accident. 2.
7-14 Starting and driving Limited-slip differential A limited-slip differential performs a special func- tion. When one wheel begins to spin on a slippery surface, a limited-slip differential diverts torque to the wheel which is not spinning, providing more traction to the vehicle. This function is effective when driving on bumpy or Z09030 snow-laden roads, and useful when moving the...

11-2 Pretrip inspection and maintenance General service precautions WARNING • Never run the engine in a poorly ventilated area. Diesel exhaust will replace the breathable air within an enclosed space, possibly resulting in unconsciousness or death. • Batteries release a gas mixture that is explosive.
Page 111
Replace filters and filter elements regularly. Blocked or damaged filters can reduce the engine’s power and impair its operation. Always use genuine Sterling parts for replacements. Use the service products rec- ommended in this manual. Use of any other parts or service products may lead to com- ponent failure.
11-4 Pretrip inspection and maintenance Tilting the cab 1 Preparation WARNING • Never tilt the cab when the vehicle is on any kind of slope. The cab will move too quickly under the effect of inertia if it is tilted on a slope, possibly causing compo- nent damage and personal injury.
Page 113
11-5 2 Raising the cab CAUTION Raise the cab slowly and gradually. Raising it quickly and using too much force could damage the cab tilt mechanism. 1. Pull out the primary release (lever A) . While holding lever A, lift the secondary release (lever Z10672 2.

11-18 Pretrip inspection and maintenance Level checking using the low oil level switch (simplified method) 1. Press the switch before starting the engine. Esti- mate the oil level from the color of the engine oil level light that comes on when the engine is started.
Page 127
11-19 CAUTION • Add oil of the same grade and viscosity as the original engine oil fill. Mixing oil can damage the engine. • Do not add more than the necessary quantity of oil. The engine can be severely damaged if the correct oil level is not maintained.
11-20 Pretrip inspection and maintenance CAUTION • Do not add more than the necessary quantity of oil. The engine can be severely damaged if the correct oil level is not maintained. • If the engine is frequently run at high speed or under heavy load, the engine oil will suffer viscosity breakdown and must be replaced sooner than scheduled.
