Powertrain Management: Service Precautions

1. Always wear appropriate eye protection.
2. Use caution when working near the exhaust to prevent the possibility of burns.
3. When servicing the fuel system use the following cautions:
a. Put a "CAUTION: FLAMMABLE" sign in the workshop.
b. Ensure the shop is equipped with a proper fire extinguisher.
c. Be sure to disconnect battery ground cable before any service work is done.
d. Exercise extreme care around the fuel systems. If a fuel leak is suspected do not use your hand to verify (Use a piece of absorbant paper), as the fuel system pressures can exceed 3,500 psi and a fuel stream of this pressure could cause serious injury.
e. Place a suitable container under the connection to be opened and wrap the connection with a rag.
f. Slowly open connection, allow pressure to escape, and catch any spilled fuel in an appropriate container.
NOTE: If available, use system bleed valve (schrader) to relieve pressure.
g. Disconnect line or hose, then plug all fittings.
h. Put any drained fuel in a non-breakable, fuel resistant container and put the lid on securely.
4. Never operate the engine with the air intake hose disconnected from the turbocharger. If the air intake hose is disconnected from the turbocharger while the engine is running, and a fluorescent light happens to be shining into the turbocharger housing, it may appear that the turbine is not spinning. The appearance that the turbine is not moving is an optical illusion created by the frequency of the fluorescent light in relation to the rpm of the turbine (similar to the effect a timing light has on a serpentine drive belt. Do not attempt to touch the turbine, as serious personal injury could result.

General Safety Precautions
- Always wear appropriate eye protection.
- Block the drive wheels before beginning any service with the vehicle on the ground.
- Never work under a vehicle supported only by a jack. Use jackstands, on a flat and level hard surface, for safe support.
- Exercise care when working with spring or tension loaded fasteners such as E-clips, or snap rings, careless removal can cause personal injury.


Supplemental Restraint System (SRS) Safety Precautions

NOTE: The following information applies only to vehicles equipped with airbag(s).

WARNING: Unintentional activation of an airbag due to improper removal, handling or installation of airbag, can lead to personal injury.

- Do not use electrical test equipment on SRS circuits. (All SRS wiring harnesses have yellow outer insulation. SRS related components are located in the steering column, center console, dash, and front fenders.)

- Disassembling or replacing airbags and related components requires special cautions and tools. SEE BODY ELECTRICAL SAFETY AND ENTERTAINMENT/PASSIVE RESTRAINS, AIR BAG.
