2026 EX5 EM-i CMSF and CMSR: keep them distinct from RCTB

A collision-assistance screen message can become a generic parts request for a “rear cross-traffic radar”. For the Mexican 2026 EX5 EM-i GF, retaining the original CMSF, CMSR or RCTB abbreviation helps the repairer identify the relevant function.

Front and rear collision mitigation are listed separately from RCTB

Page 2 lists front collision mitigation CMSF and rear collision mitigation CMSR for GF, alongside a separate rear cross-traffic braking RCTB entry. CMSR and RCTB are absent on GL, while CMSF is common to both trims.[Factory equipment][S10] This article discusses only the GF functions and does not merge them into a single sensor or control module.

The different function names do not explain in this table which hardware each uses, when it activates or how it is calibrated. [To be verified]

Original messages are more specific than a radar assumption

Retain the original vehicle message, actual circumstances and changes before and after repair. Explain whether there was a message, a change in function behaviour or an existing inspection finding. If the relevant function is still unclear, retain that unresolved status and mark it [To be verified] rather than creating a fault order for a particular radar.

This article provides no activation test. Subsequent parts supply should follow the repairer's confirmed component, original identity and trim. Use the original abbreviation to locate the issue, rather than as a part number.

Scope and verification

This article covers only Mexico, MY26, Geely STARRAY/EX5 EM-i, GF; excluding GL.[Model year and equipment][S10] Factory equipment information identifies functions and parts; it is not a fault or replacement criterion.

No public data was available in the reviewed material for operating and exit conditions of these functions, sensing and controller responsibilities, calibration or service parameters; OE numbers, service parameters, separate parts availability or compatibility and interchangeability. [To be verified] Verify compatibility or interchangeability using the VIN and local Mexican manufacturer parts catalogue.

For the parts discussed here, use the parts enquiry page.
