2001 SUZUKI GRAND VITARA Operation

0A-4 GENERAL INFORMATION
WARNING:
SDM
 During service procedures, be very careful when handling a Sensing and Diagnostic Module (SDM).
Never strike or jar the SDM.
Never power up the air bag system when the SDM is not rigidly attached to the vehicle. All SDM and
mounting bracket fasteners must be carefully torqued and the arrow must be pointing toward the
front of the vehicle to ensure proper operation of the air bag system.
The SDM could be activated when powered while not rigidly attached to the vehicle which could
cause deployment and result in personal injury.
WARNING:
Driver and Passenger Seat Belt Pretensioners
 For handling and storage of a live seat belt preten-
sioner, select a place where the ambient temperature
below 65°C (150°F), without high humidity and away
from electric noise.
 Never carry seat belt pretensioner by wire or connec-
tor of pretensioner. When placing a live seat belt pre-
tensioner on the workbench or some place like that, be
sure not to lay it with its exhaust hole (1) provided side
facing down. It is also prohibited to put something on
its face with an exhaust hole or to put a seat belt pre-
tensioner on top of another. Otherwise, personal injury
may result.
 Never dispose of live (inactivated) seat belt pretension-
ers (drive and passenger). If disposal is necessary, be
sure to activate them according to activation proce-
dures described in SECTION 10B before disposal.
 The seat belt pretensioner immediately after activation
is very hot. Wait for at least half an hour to cool it off
before proceeding the work.
 With many service procedures, gloves and safety
glasses should be worn to prevent any possible irrita-
tion of the skin or eyes.

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 CFC-12 (R-12) and the other using refrigerant HFC-134a (R-134a).
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 the descriptions (items) not found in this section, refer to the same section of the Service Man-
ual mentioned in FOREWORD of this manual.
 For basic servicing method of the air conditioning system that is not described in this section, refer
to “AIR CONDITIONING BASIC MANUAL (99520-02130)”.

AIR CONDITIONING (OPTIONAL) 1B-9
Quickly Checking of Refrigerant Charge (If
Equipped with Sight Glass)
The following procedure can be used for quickly checking whether
the A/C system has a proper charge of refrigerant or not.
1) Run engine at fast idle.
2) Operate A/C at the following conditions for a few minutes.
Main (front) A/C switch at ON position.
Rear A/C main switch at ON position (if equipped).
Front blower motor switch at max position.
Rear blower motor switch at max position (if equipped).
Air outlet control button at face position.
Temperature control lever at max cool position.
Vehicle door at all open.
Air inlet door at recirculation position.
3) Look at the sight glass (1) and compare what is observed
with the symptoms listed in the table given below.

Refrigerant Recovery, Evacuation and Charging
Operation Procedure for Charging A/C with Refrigerant
WARNING:
Your eyes should not be exposed to refrigerant (liquid).
Any liquid Refrigerant-134a escaping by accident shows a temperature as low as approx. –6 °C
(21.2 °F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a
serious injury. To protect your eyes against such accident, it is necessary to always wear goggles.
Should it occur that HFC-134a (R-134a) strikes your eye(s), consult a doctor immediately.
–Do not use your hand to rub the affected eye(s). Instead, use quantities of fresh cold water to
splash it over the affected area to gradually raise temperature of such area above freezing point.
–Obtain proper treatment as soon as possible from a doctor or eye specialist.
Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.
Refrigerant must not be handled near where welding or steam cleaning is performed.
Refrigerant should be kept at a cold and dark place. It should never be stored where a high temper-
ature is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).
Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.

Compressor Assembly
INSPECTION
1) Install manifold gauge set (1) as shown in the figure.
2) Close Hi (4) and Lo (5) side valves.
3) Run engine at fast idle.
4) Check compressor for the following items.
If any of the above checks indicated a defect, repair com-
pressor.
High pressure gauge reading is not low and low pressure
gauge reading is not higher than normal.
Metallic sound.
Leakage from compressor. CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
For identification between these two types, refer to page 66.
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 refrigerant or compressor oil will result in leakage of refrigerant, damage in parts or
other faulty condition.
When servicing the compressor, keep dirt or foreign material away from getting on or into the com-
pressor parts and system. Clean tools and a clean work area are important for proper service.
The compressor connection and the outside of the compressor should be cleaned before any “On-
vehicle” repair or before removal of the compressor. The parts must be kept clean at all times and any
parts to be reassembled should be cleaned with Trichloromethane, naphtha, kerosene or equivalent
solvent and dried with dry air. Use only lint free cloths to wipe parts.
The operations described are based on bench overhaul with compressor removed from the vehicle,
except as noted. They have been prepared in order of accessibility of the components.
When compressor is removed from the vehicle for servicing, the oil remaining in the compressor
should be discarded and new refrigerant oil added to the compressor.
Minor repair procedures may be done on the vehicle without discharging the system. Major repair pro-
cedures require that the system be discharged of refrigerant.
