Just had wheel alignment on your Swift, Vitara or S-Cross, and a lane assist warning came on shortly after, or the car's pulling slightly with lane keep active? The alignment shifted the centreline the forward camera was calibrated to. Most alignment garages don't carry the ADAS target boards needed to follow it with a recalibration. Here's what's happened and what the calibration costs.
You can drive the car. Suzuki Safety Support, Lane Keep Assist, Radar Brake Support and adaptive cruise stay limited until the camera is recalibrated to the new alignment. Normal brakes, steering and conventional cruise still work. The car is mechanically fine, the alignment was done correctly. What's left is the ADAS step.
Suzuki Safety Support reads the road through a forward camera at the top of the windscreen. The camera is calibrated to the car's geometry at the factory. Wheel alignment changes that geometry, even slightly, and the camera's reference is off. Here's what we see.
An alignment correction moves the wheels relative to the chassis. The camera at the top of the windscreen doesn't move with them, so its calibration reference now points slightly off the direction the car is travelling. Lane Keep Assist starts misreading the lane lines and either flags a fault or steers the car towards one side.
This is the central catch we hear about. Most alignment shops do tracking and toe to a high standard but don't carry the manufacturer-spec ADAS target boards required to recalibrate the camera afterwards. The wheels are correct; the ADAS step is missing. Customers find out on the drive home.
If you switch Lane Keep on after collecting the car, you'll often feel the car pull gently to one side as the system tries to centre itself against a reference that no longer matches reality. That pull is the camera asking for recalibration. Switching the system off masks it but doesn't fix it.
Suzuki Safety Support packages Lane Keep Assist with Radar Brake Support (RBS) and adaptive cruise. The camera and the radar both read from the same calibrated geometry. When one's off, several warnings can flag together on the same drive.
If suspension components were replaced or refitted as part of the work (lower arms, drop links, shock absorbers), the alignment correction often goes further. The bigger the alignment change, the more out-of-spec the ADAS calibration becomes. Worth flagging the scope of the work when you book the calibration.
The Suzuki Across is a rebadged Toyota RAV4 PHEV, so its ADAS calibration follows Toyota Safety Sense procedure with Techstream-compatible equipment, not a generic Suzuki tool. If you have an Across, mention that when you book so the workshop preps the right kit.
Less common after just an alignment, but worth ruling out. If the warning was already showing before the alignment was done, or if other repairs were carried out at the same time, the camera bracket or unit itself may be cracked. A diagnostic scan tells you which case you're in before any calibration is booked.
Worth checking first: confirm whether the warning was on before the alignment or only appeared after, and note whether the car pulls to one side with lane keep active. If Suzuki Safety Support is still showing a fault, the camera needs recalibrating to the new alignment.
On a Suzuki that means a static procedure: the workshop sets a manufacturer-spec target board at the correct distance in front of the windscreen, runs the alignment routine through Suzuki-compatible diagnostic equipment, and clears the fault codes. On the Across (rebadged Toyota RAV4 PHEV) the procedure follows Toyota Safety Sense with Techstream tooling.
It's a fixed £349 through our network: scan, calibration, certificate. The job runs inside 2 hours typically. There's no charge for the diagnostic if you decide not to go ahead. The full procedure is in our ADAS calibration guide.
Pricing is fixed across our network. Same price wherever you are in the UK. Your tier is set by what work has been done, not by your postcode or your car's make.
All prices include the diagnostic scan, the calibration procedure (static, dynamic, or both as required), a post-calibration check, and a calibration certificate. No charge for diagnostic if you decide not to proceed.

Because the alignment and the ADAS calibration are two different jobs. The alignment garage got the wheels pointing straight relative to the chassis, which is what makes the car drive properly. But the forward camera at the top of the windscreen is calibrated to the car's previous geometry.
A small change to that geometry, which is what a wheel alignment does, moves the camera's reference. The car drives fine, but Suzuki Safety Support reads the road through that camera and now its reference doesn't match reality. The calibration step is what brings the two back into agreement.
Camera and radar calibration sits in our £349 tier, which covers up to three Suzuki Safety Support modules in one visit (Lane Keep Assist, Radar Brake Support, adaptive cruise). That's the same price wherever you are in the UK. Includes the diagnostic scan, the calibration itself, and a calibration certificate.
The Across is a rebadged Toyota RAV4 PHEV, so its ADAS calibration follows Toyota Safety Sense procedure rather than Suzuki Safety Support. The job needs Techstream-compatible equipment and runs through Toyota's target board specification. The price tier is the same (£349), the procedure runs the same way as any Toyota PCS calibration. Mention it's an Across when you book so the workshop preps the right tooling.
No. Any workshop with Suzuki-compatible diagnostic equipment (or Toyota Techstream for the Across) and a calibration bay can do it, and our accredited network is set up for that. The dealer will charge their own labour rate for the same procedure. The certificate we issue is accepted by insurers and sits on the car's service history.
