To reboot a frozen SX4 S-Cross SLDA touchscreen, press and hold the power/volume knob until the unit powers off and restarts. For a full wipe, go to Settings → General (or Other) → Factory data reset (Restore factory settings) and confirm. The SLDA touchscreen is fitted to higher trims (SZ-T, SZ5); base SZ3/SZ4 cars have a simpler radio without this menu.
Overview
The SX4 S-Cross uses Suzuki's SLDA (Smartphone Linkage Display Audio) Bosch touchscreen on its higher trims. A soft reboot clears most freezes, black screens, reversing-camera faults and Bluetooth problems without losing anything; a factory reset is the step for a system that keeps playing up or before selling the car.
Applies to
2013–2021 Suzuki SX4 S-Cross Mk1 with the SLDA touchscreen (SZ-T, SZ5 trims). Base SZ3/SZ4 cars have a non-SLDA radio without the touchscreen reset menu. Exact submenu labels vary by software version.
What you’ll need
- No tools required
Step-by-step
- Park with the ignition on — Keep the car stationary and powered so the head unit stays on during the restart.
- Press and hold the power/volume knob — Hold the power/volume knob until the screen powers off and the unit restarts. Keep holding through the power-off; it typically takes several seconds.
- Let it reboot — Release once it restarts. A soft reboot keeps your settings and pairings.
- For a full factory reset instead — Go to Settings → General or Other → Factory data reset (Restore factory settings) and confirm. This erases settings and paired devices, so use it only if a reboot did not fix the fault.
Important
- A factory reset erases settings and paired devices — try a reboot first.
- Do resets with the car parked.

Will rebooting delete my Bluetooth pairings?
