Haval JOLION: Weak starter and engine will not start

Symptoms

• The starter only makes a sound or turns weakly, the headlamps dim and the horn weakens. ^[1]

Possible causes

• The manual lists this combination as signs of low battery charge. ^[1]

Checks

• Have a qualified technician check the condition and connections of the 12V (low-voltage) battery, following the vehicle's assistance requirements. ^[1]

What to do

• Repeated discharge requires inspection and repair; do not equate a successful jump start with a need to replace the battery. ^[1]

Applicability and limits

• Only applies to the corresponding JOLION configuration in the official Russian-language manual for Russia; the official website catalogue explicitly associates this manual with 2021–2024. No actual vehicle model has been linked. Do not extend to models with the same 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
