Haval H6 HEV: No start with dim lights or a weak horn
Symptoms

Possible causes

Checks
- Have a qualified technician check the 12V (low-voltage) battery and power supply condition; follow this vehicle's low-voltage emergency assistance requirements. [1]
What to do
- Repeated discharge requires investigation of the cause; do not substitute temporary charging for diagnosis or directly conclude that the traction battery is damaged. [1]
Applicability and limits
- Only applies to the corresponding H6 HEV configuration in the official Malaysian English-language manual; the manual date is not treated as an applicable model year. No actual vehicle model has been linked. Do not extend to vehicles with the same model name, other powertrains or other markets. Scope: unknown [1]
- Only applies to the specific configuration in the cited manual; do not assume applicability to all vehicles with the same model name.
