Chevrolet Tahoe 1995 - BATTERY SPECIFICATIONS


CAUTION: When battery is disconnected, vehicles equipped with computers may lose memory data. When battery power is restored, driveability problems may exist on some vehicles. These vehicles may require a relearn procedure. See COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section.

Chevrolet Tahoe 1995 - CAUTIONS & WARNINGS SUPPLEMENTAL RESTRAINT SYSTEM (AIR BAG)


NOTE: See the AIR BAGS article in the ACCESSORIES/SAFETY EQUIPMENT Section.

Modifications or improper maintenance, including incorrect removal and installation of the Supplemental Restraint System (SRS), can adversely affect system performance. DO NOT cover, obstruct or change the steering wheel horn pad in any way, as such action could cause improper function of the system. Use only plain water when cleaning the horn pad. Solvents or cleaners could adversely affect the air bag cover and cause improper deployment of the system.

WARNING: To avoid injury from accidental air bag deployment, read and carefully follow all warnings and service precautions. See appropriate AIR BAGS article in ACCESSORIES/SAFETY EQUIPMENT.

Modification to the air bag system component or wiring can adversely affect system performance and possibly cause injury.

CAUTION: The Diagnostic Energy Reserve Module (DERM) can maintain enough voltage to cause a deployment of the inflator module for up to 10 minutes after the ignition switch is turned off and the battery is disconnected. Many of the service procedures require disconnection of the inflator module to avoid an accidental deployment.

CAUTION: Disconnect negative battery cable before servicing any air bag system, steering column or passenger side dash component. After any repair, turn ignition key to the ON position from passenger's side of vehicle in case of accidental air bag inflation


Chevrolet Tahoe 1995 - AIR CONDITIONING SERVICING


CAUTION: Avoid breathing R-134a refrigerant and PAG lubricant vapors, exposure may irritate eyes, nose and throat. To remove R-134a from system use R-134a recycling equipment that meets SAE J2210 specifications. If accidental system discharge occurs, ventilate work area before resuming service.

WARNING: R-134a service equipment or vehicle A/C systems SHOULD NOT be pressure tested or leak tested with compressed air. Some mixtures of air/R134a have shown to be combustible at elevated pressures. These mixtures are dangerous and may cause fire and/or explosions. See AIR CONDITIONING SERVICE article in GENERAL INFORMATION section.


Chevrolet Tahoe 1995 - ANTI-LOCK BRAKE SYSTEM


The anti-lock brake system contains electronic equipment that can be susceptible to interference caused by improperly installed or high output radio transmitting equipment. Since this interference could cause the possible loss of the anti-lock braking capability, such equipment should be installed by qualified professionals.

On models equipped with anti-lock brake systems, ALWAYS observe the following cautions:

  • DO NOT attempt to bleed hydraulic system without first referring to the appropriate ANTI-LOCK BRAKE SYSTEM article in the BRAKES Section.
  • DO NOT mix tire sizes. As long as tires remain close to the original diameter, increasing the width is acceptable. Rolling diameter must be identical for all 4 tires. Some manufacturers recommend tires of the same brand, style and type. Failure to follow this precaution may cause inaccurate wheel speed readings.
  • Use ONLY recommended brake fluids. DO NOT use silicone brake fluids in an ABS-equipped vehicle.

Chevrolet Tahoe 1995 - REPLACING BLOWN FUSES


Before replacing a blown fuse, remove ignition key, turn off all lights and accessories to avoid damaging the electrical system. Be sure to use fuse with the correct indicated amperage rating. The use of an incorrect amperage rating fuse may result in a dangerous electrical system overload.


Chevrolet Tahoe 1995 - BATTERY WARNING


WARNING: When battery is disconnected, vehicles equipped with computers may lose memory data. When battery power is restored, driveability problems may exist on some vehicles. These vehicles may require a relearn procedure. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION section.


Chevrolet Tahoe 1995 - BRAKE PAD WEAR INDICATOR


Indicator will cause a squealing or scraping noise, warning that brake pads need replacement.


Chevrolet Tahoe 1995 - CATALYTIC CONVERTER


To prevent catalytic converter overheating, DO NOT allow engine to idle for more than 20 minutes.


Chevrolet Tahoe 1995 - DIESEL FUEL ANTI-FUNGAL ADDITIVES


CAUTION: If fuel contamination due to fungi or other microorganisms is suspected a fuel additive with a biocide may be used. Follow the manufacturers dosage as recommended on product label. Use biocides ONLY when necessary, excessive use can may cause other fuel system problems.


Chevrolet Tahoe 1995 - DIESEL FUEL CONTAMINATION


WARNING: Diesel fuel system may be contaminated with fungi or other microorganisms. Keep contaminated fuel away from open skin cuts or sores to prevent skin irritation or infection.


Chevrolet Tahoe 1995 - DIESEL FUEL REQUIREMENTS


CAUTION: All diesel engines are to use Diesel Fuel #2 when the outside temperature is above 20?F (-7?C). In temperatures that are below 20?F (-7?C) use Diesel Fuel #1, this will reduce the chance of the fuel thickening and forming wax.

NOTE: A Diesel Fuel #1 & #2 combination (Blended Fuel) may be used, and is recommended for mild winter driving.


Chevrolet Tahoe 1995 - ELECTROSTATIC DISCHARGE SENSITIVE (ESD) PARTS


WARNING: Many solid state electrical components can be damaged by static electricity (ESD). Some will display a warning label, but many will not. Discharge personal static electricity by touching a metal ground point on the vehicle prior to servicing any ESD sensitive component.


Chevrolet Tahoe 1995 - FUEL SYSTEM SERVICE


WARNING: Relieve fuel system pressure prior to servicing any fuel system component (fuel injection models).


Chevrolet Tahoe 1995 - HALOGEN BULBS


Halogen bulbs contain pressurized gas which may explode if overheated. DO NOT touch glass portion of bulb with bare hands. Eye protection should be worn when handling or working around halogen bulbs.


Chevrolet Tahoe 1995 - RADIATOR FAN


WARNING: Keep hands away from radiator fan. Fan is controlled by a thermostatic switch which may come on or run for up to 15 minutes even after engine is turned off.
