| Type | Improvement Campaign (manufacturer improvement measure / 改善対策) |
| Date filed | February 27, 2009 |

Issue
The material used in the check valve that maintains vacuum in the brake booster is inappropriate, causing the valve to stick in the closed position while the vehicle is parked or stopped after engine shutdown. If the brake pedal is applied during low-speed operation immediately after a cold start—without first pressing the accelerator pedal—the stuck check valve fails to open, resulting in insufficient vacuum in the brake booster during the first brake application. This increases the pedal effort required to achieve braking.
Corrective action
Replace the check valve on all vehicles with a corrected part.

状況
制動倍力装置の負圧を保持するチェックバルブの材料が不適切なため、エンジン停止後の駐停車中に当該バルブが閉じた状態で貼り付くことがある。そのため、始動直後のアクセルペダルを踏まない状態での低速走行中にブレーキペダルを踏んでも、チェックバルブが開かず、最初の制動時に制動倍力装置の負圧が不足し、ブレーキペダルの操作力が増大するおそれがある。
改善措置
全車両、チェックバルブを対策品と交換する。
