Renault, which returned to profit in 2021 after two years of losses, is among Western companies most exposed to Russia, where it makes 8 percent of its core earnings, according to Citibank.
In a statement, the French automaker's Russian unit said its Moscow production would stop from Feb. 28-March 5 amid "some interruptions in supplies of components."
"Interruptions are primarily caused by tighter border controls in transit countries and the forced need to change a number of established logistics routes," the unit said, without naming any countries.
Separately, a car plant in Togliatti, central Russia, may stop some assembly lines on Monday, Russia's top carmaker AvtoVAZ, which is controlled by Renault, said, citing persisting global shortage of electronic components. It said the plant should be fully operational on Tuesday.
The United States announced sweeping export restrictions against Russia on Thursday, hammering its access to global exports of goods from commercial electronics and computers to semiconductors and aircraft parts.
U.S. sanctions do not cover Renault or AvtoVAZ and target supplies of specific components.
AvtoVAZ CEO Nicolas Maure said this week his firm would seek alternative supplies of electronic chips in case U.S. sanctions curb deliveries.
Neither Renault's unit nor AvtoVAZ mentioned the invasion of Ukraine in their statements.
Even without the sanctions, sales of new cars in Russia are forecast to slow to 3.3 percent this year from 4.3 percent in 2021, because of the shortage of electronic components, logistics challenges and higher costs, according to the Association of European Business.
Russia is the Renault Group's second-largest market after France.
Any sanctions imposed by the U.S. and its allies on Russia for its actions in Ukraine could affect Renault Group, Volkswagen Group and Stellantis. All three have significant operations in Russia.
