Door SUZUKI SWIFT 2000 1.G RG413 Service Workshop Manual

0A-6 GENERAL INFORMATION
 Air bag wire harness can be identified easily as it is covered with a yellow protection tube. Be very
careful when handling it.
 When an open in air bag wire harness, damaged wire harness, connector or terminal is found,
replace wire harness, connectors and terminals as an assembly.
 Do not apply power to the air bag system unless all components are connected or a diagnostic chart
requests it, as this will set a diagnostic trouble code.
 Never use air bag system component parts from another vehicle.
 When using electric welding, be sure to temporarily disable air bag system referring to “DISABLING
AIR BAG SYSTEM” in Section 10B.
 Never expose air bag system component parts directly to hot air (drying or baking the vehicle after
painting) or flames.
 WARNING/CAUTION labels are attached on each part of air bag system components. Be sure to fol-
low the instructions.
 After vehicle is completely repaired, perform “AIR BAG DIAGNOSTIC SYSTEM CHECK” in SECTION
10B.
GENERAL PRECAUTIONS
The WARNING and CAUTION below describe some general precautions that you should observe when servic-
ing a vehicle. These general precautions apply to many of the service procedures described in this manual, and
they will not necessarily be repeated with each procedure to which they apply.
WARNING:
 Whenever raising a vehicle for service, be sure to follow the instructions under “VEHICLE LIFTING
POINTS” in this section.
 When it is necessary to do service work with the engine running, make sure that the parking brake
is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for auto-
matic transmission vehicles), Keep hands, hair, clothing, tools, etc. away from the fan and belts
when the engine is running.
 When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.
 Do not perform service work in areas where combustible materials can come in contact with a hot
exhaust system. When working with toxic or flammable materials (such as gasoline and refriger-
ant), make sure that the area you work in is well-ventilated.
 To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold, tail
pipe, muffler, etc.
 New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new or
used oil. Keep new and used oil and used engine oil filters away from children and pets.
Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory ani-
mals. Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil,
wear a long-sleeve shirt and moisture-proof gloves (such as dish washing gloves) when changing
engine oil. If engine oil contacts your skin, wash thoroughly with soap and water. Launder any
clothing or rags if wet with oil, recycle or properly dispose of used oil and filters.
 Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpect-
edly during driving, obstructing your view and resulting in an accident.

MAINTENANCE AND LUBRICATION 0B-19
ALL LATCHES, HINGES AND LOCKS
INSPECTION
DOORS
Check that each door of front, rear and back doors opens and
closes smoothly and locks securely when closed.
If any malfunction is found, lubricate hinge and latch or repair
door lock system.
ENGINE HOOD
Check that secondary latch operates properly (check that sec-
ondary latch keeps hood from opening all the way even when
pulling hood release handle inside vehicle.) Also check that hood
opens and closes smoothly and properly and hood locks securely
when closed.
If any malfunction is found, lubricate hinge and latch, or repair
hood lock system.
FINAL INSPECTION
SEATS
Check that seat slides smoothly and locks securely at any position. Also check that reclining mechanism of front
seat back allows it to be locked at any angle.
SEAT BELT
Inspect belt system including webbing, buckles, latch plates, retractors and anchors for damage or wear.
Check that seat belt is securely locked. If “REPLACE BELT” label on front seat belt is visible, replace belt.
BATTERY ELECTROLYTE LEVEL CHECK
Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case. If bat-
tery is equipped with built-in indicator, check battery condition by the indicator.
ACCELERATOR PEDAL OPERATION
Check that pedal operates smoothly without getting caught or interfered by any other part.
WARNING:
When carrying out road tests, select a safe place where no man or no running vehicle is seen so as to
prevent any accident.

MAINTENANCE AND LUBRICATION 0B-21
STEERING
Check to ensure that steering wheel is free from instability, or abnormally heavy feeling.
Check that the vehicle does not wander or pull to one side.
ENGINE
Check that engine responds readily at all speeds.
Check that engine is free from abnormal noise and abnormal vibration.
BODY, WHEELS AND POWER TRANSMITTING SYSTEM
Check that body, wheels and power transmitting system are free from abnormal noise and abnormal vibration or
any other abnormal condition.
METERS AND GAUGE
Check that speedometer, odometer, fuel meter, temperature gauge, etc. are operating accurately.
LIGHTS
Check that all lights operate properly.
WINDSHIELD DEFROSTER
Periodically check that air comes out from defroster outlet when operating heater or air conditioning.
Set mode control lever to defroster position and fan switch lever to “HI” position for this check.
RECOMMENDED FLUIDS AND LUBRICANTS
Engine oil SE, SF, SG, SH or SJ grade (Refer to “ENGINE OIL AND OIL FILTER”
in this section for engine oil viscosity.)
Engine coolant
(Ethylene glycol base coolant)“Antifreeze/Anticorrosion coolant”
Brake fluid DOT 3
Manual transmission oil Refer to “M/T OIL CHANGE” in Section 7A.

PERFORMANCE DIAGNOSIS
1) Confirm that vehicle and environmental conditions are as fol-
lows.
Vehicle is not exposed to direct sun.
Ambient temperature is within 15 – 35°C (59 – 95°F).

service valve (5), and connect low pressure charging hose
(6) to low pressure service valve (7).
4) Bleed the air in charging hoses (4), (6) by loosening their
respective nuts on manifold gauge set (3), utilizing the refrig-
erant pressure. When a hissing sound is heard, immediately
tighten nut.
5) Warm up engine to normal operating temperature (engine
coolant temperature at 80 – 90°C (176 – 194°F)) and keep it
at specified idle speed. (Radiator cooling fan should not be
working when checking pressure and temperature.)

“H” (4th position), temperature dial at “COOL”, air outlet con-
trol dial at “FACE” and fresh/recirculation control dial at
“RECIRCULATION”. (Confirm that A/C compressor and radi-
ator/condenser cooling fan are working.)
Keep all windows, doors and engine food open.
