General information
1. Steering setup and suspension geometry are determined by four base angles. All angles are expressed in degrees. The wheel pivot axis is defined as an imaginary line passing through the suspension strut axis and, if necessary, extended to contact with the road surface.
2. Camber is the angle between each wheel and a vertical line drawn through its center and the tire's contact patch when viewed from the front or rear of the vehicle. Positive camber is when the wheel is tilted outward from the vertical at the top; negative camber - when the top of the wheel is tilted inward. The camber is not adjustable.
3. Wheel yaw angle is the angle between the wheel yaw axis and a vertical line drawn through the wheel center and the tire contact area when viewed from the side of the vehicle. The inclination is considered positive when the axis of rotation of the wheel is inclined so that its imaginary extension intersects the road surface in front of the vertical; and negative when the intersection occurs behind the vertical. This angle is not adjustable.
4. Toe is a measurement that measures the difference in distance between the front and rear inner edges of the wheels when viewed from above. If the distance in the front is less than the distance in the rear, the wheels are considered to have "positive toe-in" (or simply "toe-in"). If the distance in the front is greater than the distance in the rear, the wheels are considered to have "negative toe-in" (or simply "toe-out").
5. The toe-in of the front wheels is adjusted by changing the effective length of the steering rods by screwing the rods into the ends or, conversely, unscrewing them.
6. Rear wheel alignment is not adjustable.
Checking and adjusting
7. Due to the fact that checking wheel alignment angles requires special equipment and its correct use requires the appropriate qualifications, it is recommended that checking and adjusting these parameters be entrusted to a Peugeot/Citroen dealer or other specialist. Keep in mind that similar equipment is now available at many service stations.
