BRAKE PEDAL

BRAKE PEDALPFP:46501
Inspection and AdjustmentBFS000BG
Play and clearance inspection between brake pedal and floor panel with pedal depressed.

Check brake pedal height from dash lower panel (1).

Adjust height referring to the following specifications.
ADJUSTMENT
1. Loosen stop lamp switch, brake switch and/or ASCD cancel
switch by turning it counterclockwise by 45°.
2. Loosen lock nut “A” on input rod, then rotate input rod to set,
brake pedal to the specified height, and tighten lock nut “A”.
Refer to BR-22, "
COMPONENTS" .
CAUTION:
Make sure the threaded end of input rod stays inside clevis.
3. With pedal pulled and held by hand, press stop lamp switch,
brake switch and/or ASCD cancel switch until its threaded end
contacts bracket.
4. With threaded end of stop lamp switch, brake switch and/or
ASCD cancel switch contacting bracket, rotate switch clockwise
by 45° to secure.
CAUTION:

Make sure that the clearance “C” between bracket and
end of stop lamp switch, brake switch and/or ASCD can-
cel switch is within the standard.

When locking stop lamp switch and ASCD cancel switch,
pull brake pedal to avoid moving toward the direction
where switches are being pressed.
5. Check the pedal play.
CAUTION:
Make sure that stop lamps goes off when pedal is released.
6. Start engine to check brake pedal depressed height.

PRECAUTIONS

size), components related to brake (Pad, Rotor, Caliper, etc.), Components related to engine (Muffler,
ECM, etc.), Components related to body reinforcement (Roll bar, Tower bar, etc.).

Driving in the condition of breakage or excessive wear of the suspension, tires or components related to
the brakes may cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC
system may not operate properly.

When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.

When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or the VDC OFF indicator lamp and the
SLIP indicator lamp may turn on. However, this is not a incident if normal operation can be resumed after
restarting the engine.

Sudden turns (such as spin turns, acceleration turns), drifting, etc; when VDC function is OFF (VDC OFF
switch ON), may cause that the yaw rate/side/decel G sensor system indicate a incident. However this is
not a incident if normal operation can be resumed after restarting the engine.

Checking of CVT PositionBCS001MO
1. Place selector lever in “P” position, and turn ignition switch ON. (Do not start engine.)
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transaxle body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps do not illuminate
when the selector lever is pushed toward the “R” position side
with the gear position remained in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions.
8. Make sure transaxle is locked completely in “P” position.
9. When selector lever is set to manual shift gate, make sure man-
ual mode is displayed on combination meter.
Shift selector lever to “+” and “-” sides, and make sure set shift position changes.

Is the vehicle parked on an incline?
YES >> Check the fuel level indication with vehicle on a level surface.
NO >> GO TO 4.
4. QUESTION 4
During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES >> Check the fuel level sensor unit and fuel pump. Refer to DI-24, "CHECK FUEL LEVEL SENSOR
