AV-158
< SYMPTOM DIAGNOSIS >[AUDIO SYSTEM]
NORMAL OPERATING CONDITION
PlaceIn a parking lot
When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.
If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.
Turntable
When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be eas-
ily returned to after rotating the vehicle on a
turntable with the ignition OFF.
Slippery roads On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.
Slopes When parking in sloped garages, when
travelling on banked roads, or in other cas-
es where the vehicle turns when tilted, an
error in the turning angle will occur, and the
vehicle mark may deviate from the road.
Map data Road not displayed on the map screen
When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.
Different road pattern
(Changed due to repair) If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the cor-
rect road.
Vehicle Use of tire chains When tire chains are used, the mileage is
not correctly detected, and the vehicle mark
may deviate from the correct road.Drive the vehicle for a while. If
the distance still deviates, ad-
just it by using the distance ad-
justment function. (If the tire
chain is removed, recover the
original value.)

PRECAUTIONS
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of a ll control units using CONSULT-III.
Precaution for Brake SystemINFOID:0000000001604475
• Always use recommended brake fluid. Refer to MA-12, "Fluids and Lubricants".
• Do not reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas.
• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.
• Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
• Use flare nut wrench when removing and installing brake tube.
• Always check tightening torque when installing brake lines.
• Before working, turn ignition switch to OFF and disconnect con- nectors for ABS actuator and electric unit (control unit) or battery
terminals.
• Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer to BR-35, "
Brake Burnishing
Procedure".
WARNING:
• Clean brake pads and shoes wi th a waste cloth, then wipe
with a dust collector.

WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air borne
particles or other materials.
CAUTION:
• While removing cylinder bod y, do not depress brake pedal because piston will pop out.
• It is not necessary to remove bolts on torque member and brake hose except for disassembly or replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch
brake hose.
• Do not damage piston boot.
• If any shim is subject to serious corrosion, replace it with a new one.
• Always replace shim and shim cover as a set when replacing brake pads.
• Keep rotor free from brake fluid.
• Burnish the brake pads and disc rotor mutually contacting surfaces, after refinishing or replacing rotors, after replacing pads, or if a so ft pedal occurs at very low mileage.
REMOVAL
1. Partially drain brake fluid.
2. Remove front wheel and tires. Refer to WT-48, "
Rotation".
3. Remove sliding pin bolts.

4. Hang cylinder body with a wire, and remove pads, pad retainers,shims, and shim cover from torque member.
CAUTION:
When removing the pad retainer from the torque member,
lift it in the direction indi cated by the arrow as shown so
that it does not deform.
INSTALLATION
1. Push piston in using suitable tool.
CAUTION:
In the case of replacing a pad with new one, ch eck the brake fluid level in the reservoir tank
because brake fluid returns to reservoir tank when pressing piston in.
NOTE:
Use a suitable tool to easily press in piston.
2. Apply Molykote AS-880N grease or equivalent to between shim cover and shim. Install inner shim, inner shim cover to inner pad, and install outer shim, outer shim cover to outer pad.
3. Install pad retainers and pads to torque member. CAUTION:
• Securely assemble pad retainers so that they ar e not being lifted up from torque member.
• Both inner and outer pads have a pad return system on the pad retainer. Install pad return lever
securely to pad wear sensor.
4. Install cylinder body to torque member.
5. Install sliding pin bolts, and tighten to specified torque. Refer to BR-31, "
Exploded View of Brake Caliper".
6. Check front disc brake for drag and correct as necessary.
7. Install front wheel and tire. Refer to WT-48, "
Rotation".
8. Check brake fluid level. Refer to BR-17, "
On Board Inspection".
Brake Burnishing ProcedureINFOID:0000000004894515
Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or
replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
• Be careful of vehicle speed because the brake does not operate easily until pad and disc rotor are securely seated.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool the brake.
4. Repeat steps 1 through 3 until pad and disc rotor are securely seated.
