Turbocharger Engine Starting in General The turbocharged engine should be started in a way which ensures the bearings supporting the rotating parts of the turbocharger are sufficiently lubricated.
  • Page 73 2-45 IMPORTANT INFORMATION Particulate Matter (PM) Catalytic Converter The PM catalytic converter uses an oxidation catalyst to reduce the unburnt portion of the exhaust particulate matter to water and carbon dioxide. Generally speaking, the temperature of the exhaust from diesel engines is low when the engine is idling, and as the oxidation catalyst is not activated in this condition, various types of emissions accumulate within the catalyst.
  • Page 74 2-46 IMPORTANT INFORMATION NOTE • If the engine is revved up or the vehicle is accelerated from a standstill after a period of continuous idling, a large amount of white smoke may be emitted from the exhaust pipe. This is normal and not indicative of a vehicle malfunction. •...

  • Page 578 8-68 IN CASE OF EMERGENCY When Towing To move a disabled vehicle, it is best to rely on someone in the wrecker or tow truck business. If that is not possible, follow these procedures. When towing, use appropriate equipment and comply with local legal requirements. Do not try to start the engine by towing or pushing the vehicle.
  • Page 579 8-69 IN CASE OF EMERGENCY When it is possible to operate the steering wheel, the vehicle can be towed with all wheels on the ground. However, the power steering will not be able to provide any power assist when the engine cannot be started.
  • Page 580 8-70 IN CASE OF EMERGENCY Front 1. If the vehicle is towing or being towed, firmly attach a rope to the front or rear towing hook on the same side. 2. During towing, carefully watch the stop lights of the towing vehicle in order to prevent the rope from becoming slack.

NOTE •...
  • Page 601 9-21 MAIN DATA 3. The installation shall comply with national legal requirements for the installation and use of RF-transmitting equipment in vehicles. 4. Full consideration shall be given to the positioning of RF-transmitting equipment such that electromagnetic interference (EMI) and radio frequency interference (RFI) is minimized between the RF-transmitting equipment being installed and the vehicle electrical and electronic systems.
  • Page 602 9-22 MAIN DATA Antenna 1. For RF-transmitting equipments with output power levels above 100mW (peak), an external antenna is strongly recommended. 2. The external antenna and feeder cable shall be impedance matched with a VSWR < 2.0. 3. The antenna should be a permanent-mount type located in the roof or the rear trunk lid.
  • Page 603 9-23 MAIN DATA [Ground-plane provision] When the antenna installation is to be carried out on a non-metallic surface • a ground-plane-independent antenna can be fitted directly to any surface (glass- fiber etc.) or onto a mounting bracket which may be supplied by the manufacturer, •...
  • Page 604 9-24 MAIN DATA Antenna Cable 1. Use a high quality, one piece coaxial cable (at least 95% shield coverage) that is impedance matched for the RF-transmitting equipment (VSWR < 2.0). 2. Excess coaxial cable shall not be coiled, as this may affect the tuning of the antenna as well as producing electrical interference.
  • Page 605 9-25 MAIN DATA RF-transmitting Equipment [Mounting of RF-transmitting equipment] 1. Location of a RF-transmitting equipment should be selected that provides a solid mounting point which does not interfere with the vehicle operator controls and provides adequate ventilation. 2. RF-transmitting equipment shall not be able to be damaged or its ventilation restricted.
  • Page 606 9-26 MAIN DATA Power Supply for RF-transmitting Equipment [General] 1. A dedicated supply cable should be used for the RF-transmitting equipment installation which should be as short as possible to the battery positive and negative connections. Do not connect directly to the battery pillars, but use the battery terminals provided.
  • Page 607 9-27 MAIN DATA [Supply cable and routing] 1. Heavy-duty cable of a low electrical resistance should be used on long cable runs to minimize voltage drop. 2. The cable shall be of a higher current capacity than the protection fuse, and the correct fuse shall be fitted.
  • Page 608 1. A 12 V tap shall not be taken from 24 V vehicle batteries. NOTE • Most mobile RF-transmitting equipment operates from a 12 V supply. ISUZU NMR85/NPR85/NQR75/NQR90/NLR71/NMR71 have a 24 V, so it is essential that a suitable regulator or converter be used which will provide the nominal supply voltage and current for which the RF-transmitting equipment is designed.
