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.

WARNING:
For vehicles equipped with Supplement Restraint (Air Bag) System
 Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in Section 10B in order to confirm whether you are performing service on or
near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in Section 10B before performing service on or around the air
bag system components or wiring. Failure to follow WARNINGS could result in unintentional activa-
tion of the system or could render the system inoperative. Either or these two conditions may result
in severe injury.
 Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
The link mechanism of the heater varies depending on the specifications.

For vehicles equipped with Supplemental Restraint (Air Bag) System :
 Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
 Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
CAUTION:
The air conditioning system of this vehicle uses refrigerant HFC-134a (R-134a).
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C : one using refrigerant HFC-134a (R-134a) and the other using refrigerant CFC-12 (R-12).
Be sure to check which refrigerant is used before any service work including inspection and mainte-
nance. For identification between these two types, refer to “REFRIGERANT TYPE” in this section.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.
NOTE:
For basic servicing method of the air conditioning system that is not described in this section, refer to
“AIR CONDITIONING BASIC MANUAL (Part number : 99520-02130)”.
