2001 SUZUKI GRAND VITARA N at p switch

AIR CONDITIONING (OPTIONAL) 1B-25
On-Vehicle Service
Precaution
When servicing air conditioning system, the following rules must be observed.
Piping
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling
nuts and O-ring. WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
DO NOT USE YOUR HAND TO RUB AFFECTED EYE(S).
Instead, use quantities of fresh cold water to splash it over affected area to thus gradually raise its
temperature above the freezing point.
Obtain proper treatment as soon as possible from a doctor or eye specialist.
Should liquid refrigerant HFC-134a (R-134a) get on your skin, such affected part should be treated
in the same manner as when skin is frostbitten or frozen.
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 “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:
Single A/C model is the same as SQ625 (H25 engine) model. Refer to the same section of the Service
Manual mentioned in FOREWORD of this manual.

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).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Man-
ual mentioned in the FOREWORD of this manual.
Some parts in the Power Steering Gear Box cannot be disassembled or adjusted. For detailed infor-
mation, refer to the description of “POWER STEERING GEAR BOX ASSEMBLY”.
All steering gear fasteners are important attaching parts in that they could affect the performance of
vital parts and systems, and/or could result in major repair expense. They must be replaced with
one of the same part number or with an equivalent part if replacement becomes necessary. Do not
use a replacement part of lesser quality or substitute design. Torque values must be used as speci-
fied during reassembly to assure proper retention of these parts.

3C1-2 AIR BAG STEERING WHEEL AND COLUMN
General Description
This double tube type steering column has the following three important features in addition to the steering func-
tion:
The column is energy absorbing, designed to compress in a front-end collision.
The ignition switch and lock are mounted conveniently on this column.
With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehi-
cle.
To insure the energy absorbing action, it is important that only the specified screws, bolts, and nuts be used as
designated and that they are tightened to the specified torque. When the column assembly is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller other than the one recom-
mended in this manual or a sharp blow on the end of the steering shaft, leaning on the assembly, or dropping
the assembly could shear the plastic shear pins which maintain column length and position.
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is
mounted to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the
restraint of the driver’s and passenger’s seat belts by deploying the air bags. The air bag (inflator) module
should be handled with care to prevent accidental deployment. When servicing, be sure to observe all WARN-
INGS in this section. Refer to “SERVICE PRECAUTIONS” in Section 10B.

3C1-4 AIR BAG STEERING WHEEL AND COLUMN
Steering Column
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Disable air bag system. Refer to “DISABLING AIR BAG SYSTEM” under “SERVICE PRECAUTIONS” in
Section 10B.
3) Remove steering wheel and contact coil and combination switch assembly, if necessary. Refer to “STEER-
ING WHEEL” and “CONTACT COIL AND COMBINATION SWITCH ASSEMBLY” in this section.
Perform the following procedure if not removing steering wheel and/or combination switch.
a) Turn steering wheel so that vehicle’s front tires are at straight-ahead position.
b) Turn ignition switch to “LOCK” position and remove key.
4) Remove steering column hole cover (1).
5) Disconnect all connectors for the following parts.
Contact coil and combination switch
Ignition switch CAUTION:
Once the steering column is removed from the vehicle, the column is extremely susceptible to dam-
age.
Dropping the column assembly on its end could collapse the steering shaft or loosen the plastic
shear pins which maintain column length leaning on the column assembly could cause it to bend or
deform.
Any of the above damage could impair the column’s collapsible design.
When loosening steering column mounting bolts and nuts, make sure that steering column assembly
and steering upper shaft assembly have been separated. Loosening them with steering column
assembly and steering upper shaft assembly assembled could cause damage to upper joint and
mounting bracket in steering upper shaft assembly.
NOTE:
When servicing steering column or any column-mounted component, remove steering wheel. But
when removing steering column simply to gain access to instrument panel components, leave steer-
ing wheel installed on steering column.
WARNING:
Never rest a steering column assembly on the steering wheel with air bag (inflator) module face down
and column vertical. Otherwise personal injury may result.
CAUTION:
Never turn steering wheel while steering column with steering wheel is removed. Turning steering
wheel more than about two and a half turns will break contact coil.

INSPECTION
Check steering column for damage and operation referring to
CHECKING STEERING COLUMN AND STEERING UPPER
SHAFT FOR ACCIDENT DAMAGE later in this section.
INSTALLATION
1) Be sure that front wheels and steering wheel are in straight-
ahead position.
2) If equipped with shift (key) interlock cable (1), install shift
(key) interlock cable (1) to ignition switch.
