5. Operating Instructions
5.1. Pedaling and Steering
To move the pedal car forward, the rider must pedal using the oversized anti-slip pedals. Steer the pedal car by turning the steering wheel left or right. Encourage smooth and controlled movements.
5.2. Braking
The pedal car is equipped with a dual rear wheel hand brake. To slow down or stop, squeeze the hand brake lever located near the steering wheel. Practice braking in a safe, open area until the rider is comfortable with its operation.
5.3. Coasting Shifter

Image 2: Detail of the coasting shifter. This lever allows the rider to switch between pedaling and freewheeling modes.
The coasting shifter allows the rider to switch between two modes:
- Drive Mode: In this mode, pedaling directly propels the pedal car forward.
- Freewheeling/Coasting Mode: When engaged, the pedals remain stationary while the pedal car continues to move, allowing for coasting without pedaling. This is useful for downhill sections or when being pushed.
To switch modes, move the shifter lever to the desired position. Ensure the pedal car is stationary or moving slowly when changing modes.
5.4. Seat Adjustment

Image 3: Adjusting the seat position. The lever mechanism allows for quick and easy seat adjustments.
The high-back racing seat features a 3-position easy adjust mechanism to accommodate different rider heights. To adjust the seat:
- Locate the seat adjustment lever, typically underneath the seat.
- Pull the lever to release the seat locking mechanism.
- Slide the seat forward or backward to the desired position.
- Release the lever, ensuring the seat locks securely into one of the three positions. The rider's knees should be slightly bent when the pedals are at their furthest point.
6. Maintenance
Regular maintenance will ensure the longevity and safe operation of your Kettler Kiddi-o Aero Racer Pedal Car.
- Cleaning: Clean the pedal car with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners. Rinse thoroughly and dry.
- Tire Pressure: The pneumatic air tires require regular pressure checks. Maintain the recommended tire pressure (usually indicated on the tire sidewall) for optimal performance and safety.
- Chain Guard: The chain is protected by a fully enclosed chain guard. Periodically inspect the guard for damage. While the chain is enclosed, occasional lubrication with a light bicycle chain oil may be beneficial if any squeaking or stiffness is observed.
- Fasteners: Routinely inspect all nuts, bolts, and screws. Tighten any loose fasteners to prevent parts from detaching during use.
- Storage: Store the pedal car in a dry, covered area to protect it from weather elements, which can cause rust or material degradation.
7. Troubleshooting
