*11 Although surface layer materials of rubber hoses have excellent weathering resistance, heat resistance and resistance for
low temperature brittleness, they are likely to be damaged chemically by brake fluid, battery electrolyte, engine oil and
automatic transmission fluid and their service lives are to be very shortened. It is very important to keep the hoses free
from before mentioned fluids and to wipe out immediately when the hoses are adhered with the fluids.
Since resistances for heat or low temperature brittleness are gradually declining according to time accumulation of hot or
cold conditions for the hoses and their service lives are shortening accordingly, it is necessary to perform careful inspec-
tion frequently when the vehicle is used in hot weather areas, cold weather area and/or a driving condition in which many
steering operations are required in short time. Particularly continuous work of relief valve over 5 seconds causes to reduce
service lives of the hoses, the oil pump, the fluid, etc. due to over heat.
So, avoid to keep this kind of condition when servicing as well as driving.

5) Perform these steps for the brakes connecting to the
secondary chamber of master cylinder, first, and then for
the ones connecting to primary chamber. With all proce-
dures completed, fully depress the brake pedal and keep
it in that position for approximately 20 seconds to make
sure that there is no leak evident in the entire system.

6) Perform sequence control. (With ABS model) 4-4 [W15C1].>
7) Check the pedal stroke.
While the engine is idling, depress the brake pedal with a
490 N (50 kg, 110 lb) load and measure the distance
between the brake pedal and steering wheel. With the
brake pedal released, measure the distance between the
pedal and steering wheel again. The difference between
the two measurements must be more than specified.
Specified pedal stroke:
Without ABS
90 mm (3.54 in)
With ABS
95 mm (3.74 in)
When depressing brake pedal with a 490 N (50 kg,
110 lb) load.
(1) Models without ABS
If the distance is more than specifications, there is a
possibility that air is in the brake line. Bleed air from the
brake line.
(2) Models with ABS
If the distance is more than specifications, there is a
possibility air is in the inside of the hydraulic unit.
Therefore, air must be bled from the inside of the
hydraulic unit to the brake pipes in accordance with the
bleeding sequence control.
8) Add brake fluid to the required level (MAX. level) of
reserve tank.
9) As a final step, test run the vehicle at low speed and
apply brakes relatively hard 2 to 3 times to ensure that
brakes provide normal braking action on all four wheels
without dragging and uneven braking.

16) Check the pedal stroke.
While the engine is idling, depress the brake pedal with a
490 N (50 kg, 110 lb) load and measure the distance
between the brake pedal and steering wheel. With the
brake pedal released, measure the distance between the
pedal and steering wheel again. The difference between
the two measurements must be less than specified.

If the distance is more than specifications, there is a
possibility that air is in the brake line. Bleed air from the
brake line.
17) Turn ignition switch OFF.
18) Disconnect select monitor or diagnosis terminal.
19) Add brake fluid to the required level (MAX. level) of
reserve tank.
20) As a final step, test run the vehicle at low speed and
apply brakes relatively hard 2 to 3 times to ensure that
brakes provide normal braking action on all four wheels
without dragging and uneven braking.

1. Supplemental Restraint System
“Airbag”
Airbag system wiring harness is routed near the instrument
panel, heater unit, blower motor and control unit.
CAUTION:

All Airbag system wiring harness and connectors
are colored yellow. Do not use electrical test equip-
ment on these circuit.

Be careful not to damage Airbag system wiring har-
ness when servicing the instrument panel, heater unit,
blower motor and control unit.
2. Heater Unit
A: REMOVAL AND INSTALLATION
1) Disconnect GND cable from battery.
2) Remove heater hoses (inlet, outlet) in engine compart-
ment.
NOTE:
Drain as much coolant from heater unit as possible, and
plug disconnected hose with cloth.

3) Remove instrument panel.

4) Remove steering support beam.

5) Remove evaporator. (With A/C model)
